This document provides an overview of a lecture on the renal system. It discusses renal anatomy and physiology, assessment of renal health, interpretation of kidney function labs, acute and chronic kidney disease, dialysis options, and kidney transplantation. The objectives are to understand renal structures and functions, diseases of the kidney like pyelonephritis and glomerulonephritis, compare acute and chronic kidney disease, interpret kidney labs, explain nursing care of renal patients, and discuss dialysis and transplantation. Fun facts, diseases statistics, and the functions of kidney structures like the nephron are also reviewed.
Sinus tachycardia is characterized by a heart rate over 100 beats per minute originating from the sinus node. It can be a normal response to exercise or stress or indicate underlying conditions like heart failure. Symptoms may occur if the heart rate is very fast or the patient has heart disease. Treatment involves addressing the underlying cause and reducing stress or anxiety.
Cardiac tamponade occurs when fluid accumulates in the pericardium and compresses the heart, restricting blood flow. It has an incidence of about 2 in 10,000 people. Causes include aortic aneurysm, cancer, heart attack, infection, and other conditions. Symptoms include low blood pressure, distended neck veins, muffled heart sounds (Beck's triad). Diagnosis involves echocardiogram, x-rays, and other imaging tests. Treatment focuses on draining fluid via pericardiocentesis and supporting blood pressure/heart function. Nursing care monitors symptoms, vital signs, and educates the patient.
This presentation discusses the use of the drug Topiramate in treating alcohol withdrawal and dependence. It provides background on alcohol dependence syndrome and current treatment methods. The presentation summarizes evidence from one randomized controlled trial that found Topiramate effective in reducing drinking and promoting abstinence compared to placebo. It concludes that Topiramate may be an effective treatment for both alcohol withdrawal and preventing relapse, but that further research is still needed.
This document discusses bradycardia, including its definition, causes, signs and symptoms, and treatment. Bradycardia is defined as a resting heart rate below 60 beats per minute. It can be caused by physiological factors like athletic training or pathological factors like drugs, metabolic disorders, or cardiac issues. Symptomatic bradycardia requires three criteria: a slow heart rate, symptoms, and symptoms caused by the slow heart rate. Common symptoms include chest pain, shortness of breath, weakness, and syncope. The bradycardia algorithm outlines assessing perfusion and treating with atropine, pacing, or vasopressors like dopamine or epinephrine depending on the situation.
This document provides information on ischemic heart disease (IHD), also known as coronary artery disease (CAD). It defines IHD as a condition caused by atherosclerosis of the coronary arteries, leading to inadequate blood flow to the heart muscle. Risk factors include dyslipidemia, family history, smoking, hypertension, diabetes, age, and obesity. The management of IHD involves identifying risk factors, lifestyle modifications, medical treatments like nitrates, beta-blockers, and calcium channel blockers, and possible revascularization procedures.
Renal replacement therapy replaces the normal filtering function of the kidneys using modalities like hemodialysis, peritoneal dialysis, or renal transplantation. Peritoneal dialysis uses the peritoneal membrane for diffusion and ultrafiltration of solutes and fluid, while hemodialysis uses an external dialyzer to filter the blood via diffusion and convection. Both therapies aim to control uremia, electrolyte abnormalities, and fluid balance. Choice of modality depends on factors like age, cardiovascular status, and expertise available. Continuous renal replacement therapy is preferred for critically ill patients who are hemodynamically unstable.

There are two main types of renal failure - acute and chronic. Acute renal failure is a sudden onset condition characterized by oliguria/anuria and a rapid rise in BUN and creatinine levels. Chronic renal failure is a long-term condition that impairs homeostasis due to structural kidney damage and leads to metabolic complications like acidosis, hypocalcemia, and hyperphosphatemia. The causes and stages of both acute and chronic renal failure are described.
The document provides an overview of cardiac anatomy, including the layers of the heart muscle (endocardium, myocardium, epicardium), the four chambers (two atria and two ventricles), and the valves (atrioventricular and semilunar). It describes the cardiac cycle of blood flow from the veins to the lungs and throughout the body, powered by the muscular contraction of the myocardium under control of the heart's electrical conduction system.
Psychogenic polydipsia is excessive thirst and compulsive water drinking occurring in patients with psychiatric disorders. It may result in hyponatremia due to low plasma osmolality. Treatment involves correcting any hyponatremia, fluid restriction, and treating the underlying psychiatric illness. Behavioral therapy focuses on restricting water intake through stimulus control and coping skills. Pharmacological treatments include atypical antipsychotics or lithium.
Cardiac failure, also known as heart failure, is a disorder where the heart loses its ability to pump blood efficiently. It occurs when the heart's output is inadequate to supply oxygen to the body. There are two main types: diastolic dysfunction, where the heart cannot fill with enough blood, and systolic dysfunction, where it cannot pump with enough force. Treatment depends on the severity and includes drugs like ACE inhibitors, ARBs, diuretics, vasodilators, and inotropic agents.
Angina pectoris, or angina, is a type of chest pain caused by reduced blood flow to the heart. There are different types of angina that vary based on factors like when the pain occurs and how long it lasts. Risk factors include obesity, high cholesterol, smoking, and diabetes. Treatment involves medications like nitroglycerin to relieve symptoms as well as procedures like CABG to restore blood flow if needed. Nurses manage angina by addressing pain, activity tolerance, and providing patient education.
This document discusses hyponatremia (low sodium levels in blood). It begins by defining hyponatremia as a sodium level below 135 meq/L. It then describes the causes and symptoms of hyponatremia, which can include headache, vomiting, seizures and coma depending on severity.

This document provides an overview of chronic kidney disease and end-stage renal disease. It describes how chronic kidney disease develops through a vicious cycle where initial kidney injury leads to adaptive changes in the remaining nephrons that then cause further injury. As kidney function declines below 10-15% of normal, the condition progresses to end-stage renal disease where dialysis or transplantation is needed to survive. The document outlines the pathophysiological changes that occur as kidney function deteriorates, including impaired concentration and dilution of urine, fluid and electrolyte imbalances, and accumulation of waste products that can damage organs if kidney function is not replaced.
Mitral valve prolapse (MVP) is a condition where the mitral valve leaflets bulge into the left atrium during systole. It is usually a benign condition but can sometimes lead to complications. The document discusses the anatomy, classification, pathology, clinical presentation, diagnosis and management of MVP. Echocardiography plays a key role in diagnosis by visualizing the prolapsed mitral valve leaflets. Treatment involves medication for symptoms and mitral valve surgery if MVP causes significant mitral regurgitation.
Cardiac tamponade is a serious medical condition where blood or fluid fills the space between the sac surrounding the heart (pericardium), putting extreme pressure on the heart and preventing it from filling with blood properly. This can lead to organ failure, shock, and even death if not treated. Causes include infectious diseases, malignancies, anticoagulation medications, and connective tissue diseases. Symptoms include chest pain, difficulty breathing, fainting, and pale/gray skin color. Diagnosis involves physical exam, imaging like echocardiograms, and lab tests. Treatment consists of oxygen, fluids, medications, and procedures to drain excess fluid from the pericardial space.

Exercise testing is used to detect cardiovascular disease, reproduce symptoms, screen for exercise programs, and monitor therapeutic responses.
Anatomy and physiology of renal system.pptRakshatNayak1
The kidneys are paired organs located in the posterior abdominal cavity that filter blood to remove waste and regulate fluid balance. Each kidney contains approximately 1-3 million functional filtration units called nephrons. Nephrons are composed of a glomerulus for blood filtration and a tubule for reabsorption and secretion. Filtration in the glomerulus is selectively permeable based on size and charge. Tubular reabsorption and secretion help regulate water, electrolyte and acid-base balance. The countercurrent mechanism in the loop of Henle and vasa recta help concentrate urine by creating a hypertonic medullary environment.
The document provides information on inferior wall myocardial infarction (MI), including:
1. Definitions, epidemiology, etiology, clinical features, diagnosis, treatment and complications of inferior wall MI are discussed. Worldwide over 7 million people experience STEMIs or NSTEMIs annually.
2. Diagnosis involves ECG, cardiac imaging, cardiac biomarkers like troponin and CK-MB. Reperfusion therapy within 6 hours includes PCI or thrombolysis. General treatment measures include aspirin, clopidogrel, anticoagulants, analgesics, beta-blockers, nitrates and oxygen.
3. The history of pioneers in cardiology and development of techniques like echocardi
Polyuria is defined as excessive urine production of more than 3 liters per day in adults. It can be caused by either water diuresis or solute diuresis. Water diuresis is characterized by dilute urine of less than 250 mosmol/L and is caused by problems with antidiuretic hormone production or kidney response. Solute diuresis produces urine of more than 300 mosmol/L and is caused by increased glucose, urea, or other solutes. Polyuria can be pathological due to diseases like diabetes, pharmacological due to medications or fluids, or physiological for compensatory reasons.

The goals of treatment are to delay disease progression, manage complications, and improve quality of life.
Chronic kidney disease (CKD) consists of a spectrum of different pathophysiologic processes associated with abnormal kidney function, and a progressive decline in glomerular filtration rate (GFR).
This document provides information about chronic kidney disease including:
1. Chronic kidney disease is the slow loss of kidney function over time that can be caused by conditions like diabetes or high blood pressure.
2. As kidney function declines, waste builds up in the body and patients may experience symptoms like fatigue or swelling.
3. When kidney function drops below 10%, the final stage of kidney disease called end-stage renal disease is reached requiring dialysis or transplant.
Tubulointerstitial nephropathy can be acute or chronic and is characterized by inflammation and scarring of the kidney tubules and surrounding tissue. Acute causes are often toxins or ischemia while chronic causes include obstructive uropathy, vesicoureteral reflux, analgesics, and heavy metals. Polycystic kidney disease is a common hereditary condition where numerous cysts develop in the kidneys, often leading to end-stage renal disease. Medullary sponge kidney is a benign condition present from birth that causes kidney cysts and issues like hematuria, urinary tract infections, and kidney stones.
The kidneys play an important role in removing waste and regulating various functions in the body. Chronic kidney disease occurs when the kidneys become damaged and can no longer filter blood properly. It has stages from mild to severe and can progress to end-stage renal disease where dialysis or transplant is needed to survive. Treatment focuses on managing symptoms, slowing progression, and replacing kidney function through dialysis or transplant for end-stage disease.

</SUMMARY>
1) Acute renal failure is a sudden reduction in kidney function that results in waste accumulating in the blood and is categorized as pre-renal, renal, or post-renal based on the underlying cause.
2) Pre-renal acute renal failure is caused by problems affecting blood flow to the kidneys such as dehydration, blood loss, or heart issues. Renal acute renal failure involves direct damage to the kidney itself from issues like acute tubular necrosis. Post-renal acute renal failure is caused by problems blocking urine flow out of the kidneys.
3) Symptoms can include weakness, fatigue, edema, and electrolyte imbalances. Treatment involves addressing the underlying cause, maintaining
Cirrhosis is scarring of the liver caused by injury and repair over time. Portal hypertension occurs when blood pressure increases in the portal vein system that drains the gastrointestinal tract into the liver. Complications of portal hypertension include variceal bleeding, ascites, and hepatic encephalopathy. Treatment involves controlling the underlying cause, lowering portal pressure through medications or procedures like TIPS, and managing complications such as bleeding varices through endoscopic therapy.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
low birth weight presentation. Low birth weight (LBW) infant is defined as the one whose birth weight is less than 2500g irrespective of their gestational age. Premature birth and low birth weight(LBW) is still a serious problem in newborn. Causing high morbidity and mortality rate worldwide. The nursing care provide to low birth weight babies is crucial in promoting their overall health and development. Through careful assessment, diagnosis,, planning, and evaluation plays a vital role in ensuring these vulnerable infants receive the specialize care they need. In India every third of the infant weight less than 2500g.
Birth period, socioeconomical status, nutritional and intrauterine environment are the factors influencing low birth weight
Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.
8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Kidney transplant
3. Objectives
Identify and define the anatomic
structures and physiological functions
of the kidney.
Understand specific diseases of the
kidney including pyelonephritis,
glomerulonephritis, and polycystic
kidney disease.
Compare and contrast acute and
chronic kidney disease, including
causes, classification, treatment,
management, and prognosis.

health, prevention of renal
complications, and management of
patients with kidney disease.
Compare and contrast hemodialysis
and peritoneal dialysis, the mechanism
and rationale of each.

process, maintenance, prognosis, and
ethics surrounding transplantation.
4. Some “fun” facts
What percentage of your kidney function can you lose before you might
need dialysis?
Chronic kidney disease is more common in men or women?
Your entire volume of blood and fluids will circulate how many times
in an hour? (approximately)
How much of that blood and circulated fluids becomes urine?
____% of your blood supply is in your kidneys at any given time.
5. Some “not so fun” facts
African Americans are 4x more likely to develop chronic kidney disease
(CKD) than Caucasian Americans are. Hispanic Americans are 1.5x
more likely to develop CKD than non-Hispanic whites.
Of all adults with hypertension, about 20% have CKD.
Of all adults with diabetes, about 35% have CKD.
Of all adults older than age 65, about 40% have CKD.
6. Functions of the Kidney
Big picture function: maintain homeostasis in the body
Major functions: filtration and collection
Other functions: helps regulate blood pressure, osmolarity and
electrolyte concentrations in the blood, helps regulates pH, stimulates
red blood cell production, helps regulate calcium and vitamin D levels.
10. A musical number to help remember!
https://www.youtube.com/watch?v=kVF65d1X8SU
11. Follow the blood and
filtrate/urine through
the kidney:
Where does the blood enter the
kidney?
What happens when it enters the
glomerulus?
Where does the filtrate go?
PCT... What’s reabsorbed?
How DOES the Loop of Henle
work?
DCT… now what’s reabsorbed?
Collecting duct is fed by what?
Collecting duct empties where?
Ok, back to the vasculature, how
and where does blood exit the
kidney?
12. GFR
The afferent and efferent
arterioles, renal artery
and renal vein, all need to
be the right size with no
obstructions to keep the
glomeruli filtering at a
steady rate.
What happens if there is
obstruction or if the size
of the lumen is changed?
13. Nursing Assessment
Many of the same questions as urinary assessment
Medications
Recent infections
Edema

17. Pharmacology: Antihypertensives
ACE inhibitors
Angiotensin I cannot convert to
angiotensin II. Less angio II means
more vasodilation, and less
constriction of the efferent
arteriole in the kidney
Generally well tolerated and
inexpensive
Captopril is recommended
specifically for nephropathy, but
any ACE will work
Nursing considerations: BP
assessment, ensuring daily doses
ARBs
Blocks Angiotensin II receptors on
the blood vessel walls
Lower risk of cough and
hyperkalemia
Newer, more expensive
Preferred for patients who cannot
tolerate ACE inhibitors
Cozaar (losartan) and Avapro
(irbesartan) are preferred ARBs for
nephropathy, but again, any ARB
will work
Nursing considerations: same as
ACE inhibitors
18.
19. Pharmacology: Diuretics
Basic mechanism of diuretics: prevent sodium and chloride from being
reabsorbed, thereby preventing the passive reabsorption of water.
Loop Diuretics (Lasix [Furosemide])
Act on the ascending Loop of Henle
where a substantial amount of all NaCl
is reabsorbed (about 20%) producing
profound diuresis
IV or oral
Serious side effects:
Hyponatremia, hypochloremia,
dehydration, hypotension, hypokalemia
Nursing considerations: you tell me-
critical thinking time!
Potassium Sparing Diuretics
(Spironolactone or triamterene)
Acts on the distal nephron, most
reabsorption has already occurred
Blocks the action of aldosterone, thus
retaining potassium and excreting sodium
Scant diuresis, takes 1-2 days to start
taking effect
Side effects: hyperkalemia, endocrine
effects
Nursing considerations: avoid salt
substitutes which often contain potassium
23. Polycystic Kidney Disease
Most common life-threatening inherited disease in the world
Autosomal dominant, if 1 parent has disease, 50% chance of passing it to
child
Accounts for 10-15% of CKD patients in the US
Presents either in childhood or is latent until age 30s-40s
Fluid-filled cysts form in the cortex and medulla, compressing the nearby
tissues. Most are several mm to several cm in size
Asymptomatic in early stages, presents with HTN or hematuria
Sometimes diagnosed incidentally because of UTI or kidney stone
No treatment other than symptomatic- managing pain and infections, kidney
diet, fluid restriction, antihypertensive drugs, etc. Eventually may progress
ESRD and need dialysis or a transplant
24. Pyelonephritis, Etiology
Almost always an ascending bacterial infection- a UTI gone really bad!
Occasionally a descending bacterial infection, endocarditis or sepsis
Rarely caused by a virus, fungus, or protozoa
Inflammation starts in the cortex then spreads to the medulla
Prompt treatment is required, 15% of cases of urosepsis will lead to
death via septic shock if untreated
Can cause abscesses
Pregnancy, pre-existing vesicoureteral reflux or obstruction are risk
factors
25. Pyelonephritis, Clinical Manifestations
Range of symptoms, from mild fatigue to chills/fever, vomiting, flank
pain, malaise, and urinary complaints such as dysuria, frequency, and
sudden urge to urinate
CVA tenderness usually present
Fever may be present, with related tachycardia and tachypnea
U/A shows pyuria, bacteriuria, and hematuria, possibly casts
CBC shows leukocytosis
Ultrasound may identify anatomic abnormalities, abscess, or calculi
26. Pyelonephritis, Nursing Interventions
History and assessment
Vital signs
Obtain urine culture and sensitivities
Goals
Normal renal function
Normal body temperature
No complications
Relief of pain
No recurrence of symptoms
27. Pyelonephritis, Nursing Interventions
Teaching
Encourage adequate fluid intake
Encourage rest
UTI prevention/recurrence prevention
Rationale of therapy
Medications
Antibiotics
Pain/antipyretics
Follow up care and repeat UA/UC
28. Chronic Pyelonephritis
Kidneys become atrophic and lose function due to fibrosis/scar tissue
formations, an inflammatory response, usually in response to multiple
infections of the upper urinary system
Presents as decreasing kidney function, elevated Cr
Diagnosed by imaging- ultrasound or CT
Biopsy done to determine extent of damage, how deep inflammation has
intruded, and which structures are affected
Treatment starts with eradicating the underlying cause, but the damage is
usually permanent
Prognosis: one or both kidneys affected? Extent of damage? Most patients
with chronic pyelonephritis will progress to End Stage Kidney/Renal Disease.
(ESKD, ESRD)
29. Case Study 1
See Handout 1
Any questions about s/s or abbreviations?
Discuss which clinical manifestations cause you to suspect
pyelonephritis. Where there any other conditions that you considered?
What risk factors does she have for UTI? Pyelonephritis?
Acute or Chronic?
What’s the appropriate treatment?
Specific teaching?
Follow up needed?
30. Glomerulonephritis, Etiology
3rd leading cause of ESRD in US
Acute (also known as Rapidly Progressive GN, or RPGN) or Chronic
Immunologic process that can either swiftly or slowly cause progressive
damage to the glomeruli
Most commonly seen form of acute GN is Acute Poststreptococcal
Glomerulonephritis (APSGN). Exact etiology is unknown
Chronic GN has a more insidious onset, can be caused by many types of
immune or vascular conditions, or co-morbidities that can cause scarring of
the glomeruli: lupus, vasculitis, diabetic neuropathy, HTN…
Often diagnosed incidentally, can be confirmed by CT, ultrasound, or biopsy
31. Glomerulonephritis, Clinical Manifestations
Generalized edema
Tends to start in “leakier” vessels like capillaries around the eyes-
periorbital edema often seen first, but eventually progresses to whole body
edema, including ascites
Hypertension
Oliguria, or hematuria with a smoky/rusty appearance, proteinuria
Abdominal or flank pain
32. Glomerulonephritis, Nursing Assessment
Renal assessment
Health history
How is urination?
Smoky urine is a sign of bleeding in the upper urinary system
Edema/weight gain
CVA tenderness
Recent infections
Vital signs- BP and temp… why?
Labs- what should be ordered?
Large numbers of erythrocytes and erythrocyte casts in urine are a
hallmark of glomerulonephritis
33. Glomerulonephritis, Management
Antibiotics only if acute infection (i.e. strep throat) is still present
About 95% of APSGN patient recover or improve with conservative
management. About 5-15% of patient will develop chronic GN and about 1%
will progress to full renal failure
Supportive treatments
Rest is indicated until kidney is recovered (in acute GN)
Pain management
Hypertension is managed with ACEIs or ARBs
Edema is managed with fluid and sodium restriction and diuretics
Low protein diet may be recommended if BUN is high or if there is high
proteinuria
Support for CKD management if needed
34. Glomerulonephritis, Nursing Interventions
Frequent vitals, especially blood pressure as this will be indicative of
kidney function
I/Os
Daily weights
Repositioning/preventing injury to edematous skin
Teaching
Diet: low sodium, low protein, fluid restriction
Worsening of symptoms
35. A Note About Nephrosis (aka Nephrotic Syndrome)
Similar s/s and outcomes to glomerulonephritis, but not caused by
inflammation of the glomeruli. Exact etiology unknown, but there appears to
be either idiopathic or acquired injury to the basement cells and/or podo cells
that make up the junction of the glomerulus and Bowman’s capsule, allowing
proteins to enter the capsule and be excreted.
Key differences: no blood in urine, usually very high proteinuria.
Eventually, the loss of the proteins leads to hyperalbuminemia, increased
triglycerides, anorexia/malnourishment, hypercoagulability, decreased immune
response, and decreased calcium absorption leading to skeletal deformities and
hypoparathyroidism.
Treatment is essential the same as GN, management of underlying disease,
management of symptoms, balancing fluid, sodium, and proteins. However, also
should consider risk of infection and thrombus formation.
36. AKI vs CKD
Acute kidney injury is a catch-all term for loss of kidney function (from
slight deterioration to severe) that happens in a rapid period of time
(hours to days)
Chronic kidney disease is another catch-all term for loss of kidney
function that happens over a longer period of time, usually years
AKI has the potential for recovery, CKD is progressive and irreversible
AKI is usually seen in patients who have other life-threatening
conditions, and affects about 5% of hospitalized patients. CKD is
usually seen in patients who have other chronic illnesses/diseases that
are not immediately life threatening. 1 in every 9 Americans has CKD
37. AKI Etiology
Can be caused by numerous conditions, classified by where the problem
originates:
Pre-renal causes are independent of the actual kidney, caused by things further
upstream i.e. hypovolemia, decreased cardiac output, and decreased renal blood
flow. Essentially, they all lead to low perfusion/ischemia of the renal organ
Intrarenal (or intrinsic) causes are etiologies that cause harm to the renal tissue,
affecting the nephron function. Common causes are nephrotoxic injury, interstitial
nephritis, prolonged ischemia, and other renal disorders such as
glomerulonephritis. The tissue most likely to be damaged is the epithelium of the
tubules, causing Acute Tubular Necrosis
Post-renal causes are related to obstruction of urine out of the kidney, or urinary
reflux. Examples are BPH, bladder cancer, calculi, strictures, or trauma

41. Oliguric Phase
Oliguric phase begins within 1-7 days of injury, if due to ischemia it starts within 24
hours. Nephrotoxic drug response, though, may be delayed up to a week
About 50% of AKI patients will not be oliguric, delaying diagnosis. Generally,
patients are anuric if post-renal, oliguric if pre-renal, and non-oliguric if intrarenal
If AKI is mild, and especially in pre-renal hypovolemia, fluids can correct AKI
In more severe injuries, patients will have fluid retention, requiring careful
regulation of sodium and fluids. Edema, pulmonary edema, and pleural and cardiac
effusions become a concern
Hyperkalemia, especially in trauma/burn patients and those already in metabolic
acidosis. Can cause cardiac dysrhythmias.
Heme/Infectious disorders: at higher risk for eosinophilia, leukocytosis, often seen in
multi-system organ failure, low protection against urinary/lung infections
Waste product accumulation: creatinine and BUN will rise, neurological
disturbances such as fatigue, seizures, and coma are possible
42. Diuretic Phase
Kidneys recover the ability to excrete urine, but not to concentrate it.
Patients pass between 1-5 liters of urine per day
At risk for hypovolemia, hypotension, hyponatremia, and hypokalemia
Lasts 1-3 weeks, labs should begin normalizing toward the end of this
phase
43. Recovery Phase
Kidneys resuming their usual functions, GFR increases, creatinine and
BUN are decreasing toward normal values
Greatest improvements are seen in the first 1-2 weeks, but may take up
to 12 months for full recovery
Outcome is determined by patient’s overall health, severity of the
kidney failure, and complications. Older adults do not recover as much
function as younger adults. Some patients never recover function and
progress to ESKD. However, most patients recover to the point of being
clinically asymptomatic, although there is scar tissue and an
insignificant loss of kidney function.
44. AKI Management
Fluid volume management: make sure there is enough volume to have
adequate cardiac output to perfuse the kidneys (and rest of the body).
Administer diuretics in low doses. Fluid restriction- can have
600mL+all losses in previous 24 hours
Hyperkalemia: lower potassium by administering IV insulin to move
potassium into cells, sodium bicarb to correct acidosis and shift
potassium into cells, calcium gluconate to prevent cardiac
dysrhythmias, Kayexalate to exchange potassium for sodium in the
bowel and excrete the potassium, or hemodialysis to remove
potassium. When less critical, restrict dietary potassium to 40mEq/day
Continuous Renal Replacement Therapy
45. AKI Nursing Assessment
Monitor vitals
I/O, measure, calculate daily total, fluid replace/restrict, examine urine
color, follow labs such as urine protein, blood, and sediment
Assess oral mucosa for dryness, inflammation
Good oral care to prevent stomatitis, caused by ammonia in saliva
Auscultate lungs for crackles, rhonchi, or diminished breath sounds
Auscultate heart for murmurs, pericardial friction rub, assess EKG
Review lab data, especially CBC, BMP, Creatinine, BUN
Daily weight, at same time with same scale
46. AKI Nursing Planning
Diagnoses
Excess fluid volume related to kidney failure and fluid retention
Risk for infection related to invasive lines, uremic toxins, and altered immune
responses secondary to kidney failure
Fatigue related to anemia, metabolic acidosis, and uremic toxins
Anxiety related to disease processes, therapeutic interventions, and uncertainty of
prognosis
Potential complication: dysrhythmias related to electrolyte imbalance
Goals
Completely recover without any loss of kidney function
Maintain normal fluid and electrolyte balance
Decrease anxiety
Adhere to and understand the need for careful follow-up care
47. Case Study
Handout 2
What are you thinking for a diagnosis?
Risk factors of kidney failure?
Significance of poor skin turgor?
Significance of S₃ heart sound?
Looking at the labs, how would you classify the injury?
Why not glomerular disease?
Calculate the BUN: Cr ratio. Does this confirm suspicions about etiology?
First intervention?
Then what?
Prognosis?
48. CKD Basics
Defined as either the presence of kidney damage or a GFR
< 60mL/Min/1.73m² for longer than 3 months
Classified by stages, Stages 1-5, normal GFR to ESRD
Can be asymptomatic, underdiagnosed, and undertreated. May not be
treated until there has been a significant loss of nephron function
Prognosis is variable, some people live long, normal, active lives, others
progress to ESRD rapidly
Leading causes are diabetes (50% of CKD patients) and HTN (25%)
As kidney function declines, every system in the body is affected
51. CKD Management
Similar to the other kidney diseases we’ve discussed: treat underlying
cause if possible, manage symptoms, and prevent worsening of
condition when possible
What are some treatments/drugs you might expect to see in a patient with
CKD? (Refer to previous slide for ideas.)
52. CKD Nursing Assessment
Obtain thorough health history, including any existing kidney disease or family
history of kidney disease
Ask about the use of medications, including OTC and herbal supplements, to
determine if any nephrotoxic agents are present, or if anything might be contributing
to hypertension (exacerbating CKD)
Decongestants such as Sudafed cause vasoconstriction
Antacids can contain high levels of salt contributing to HTN, and also can interfere with
the absorption of some medications
NSAIDs are known to contribute to AKI and the progression of CKD, especially when
taken frequently at high doses
Assess dietary habits, weight trends, are there any problems with intake or
fluctuating weight?
Remember that CKD is a chronic illness that has no cure, only progression toward
ESRD, and it affects every part of the patient’s life. Questions about coping,
adherence to treatment, support, etc. are all appropriate
53. CKD Nursing Diagnosis and Goals
Excess fluid volume related to impaired kidney function
Risk for electrolyte imbalance related to impaired kidney function resulting in
hyperkalemia, hypocalcemia, hyperphosphatemia, and altered vitamin D
absorption
Imbalanced nutrition: less than body requirements related to restricted intake
of nutrients (especially protein), nausea, vomiting, anorexia, and stomatitis
Many additional depending on current complications and presentation
Goals:
That a patient with CKD will:
Demonstrate knowledge of and ability to comply with therapeutic regimen
Participate in decision making for plan of care and future treatment modality
Demonstrate effective coping strategies
Continue with activities of daily living within physiologic functions
54. CKD Nursing Implementation
Health promotion
Encourage on-time check ups, appropriate follow up care, frequent labs. Make a
plan with the patient for medication management. Encourage patient to meet
with dietitian
Teach patient to take daily BP and weight, identify signs of electrolyte
imbalance, fluid overload
Give practical tips about diet and fluids - simple charts with examples of
approved or discouraged foods. Measurement systems for fluid restrictions.
Use of gum or hard candy to moisten mouth
Encourage patient to find and use support. Talk about concerns regarding
lifestyle changes, living with a chronic illness, or big decisions such as
transplant
55. Caution foods:
High Sodium
Most sauces and gravies, including meat
tenderizer and soy sauce
Processed lunch meat
Smoked meats/fish (BACON!)
Pickled foods
High Potassium
Fruits such as apricots, avocado, bananas,
citrus, pears, nectarines…
Veggies such as celery, dry beans,
potatoes, leafy greens, tomatoes, squash…
Whole grains, especially those containing
bran
Peanuts (including PEANUT BUTTER)
Sardines and clams
Milk (and ice cream, pudding and yogurt)
High Phosphorus
Milk, cheese, custard, pudding, ice cream
Dried beans or peas
Nuts
CHOCOLATE!
Dark cola
Sausage and hot dogs.
High Protein
Meats and fish
Dairy
Eggs
Nuts
Soy/tofu
56. End Stage Renal Disease
Kidney function is at 10% or less, GFR is less than 15mL/min
Options are:
Dialysis
Hemodialysis
Peritoneal dialysis
Transplantation
Live donor organ
Deceased donor organ
Transplantation may not be an option for all patients because of lack of a suitable
donor kidney, patients may be physically or mentally unsuitable for the
transplantation process, some patients may be opposed to transplantation for
religious or ethical reasons
61. Complications of Dialysis
HD
Hypotension during tx, from rapid loss
of vascular fluid
Muscle cramps- unknown etiology,
usually seen/are worst in 1st month of
tx
Loss of blood can occur from operator
error, accidental rupture of dialysis
membrane, accidental disconnection of
tubing during tx, post-needle removal
Hepatitis B and C have outbreaks
among dialysis population, usually due
to breaks in infection control processes.
At this time, Hep C is more prevalent,
about 10% of HD patients are positive
PD
Exit site infection
Peritonitis. Tx can be oral, IV or
peritoneal abx. Repeated infections cause
adhesions, requiring cessation of PD
Hernias, from large volumes
Low back pain from increased pressure
Bleeding from catheter insertion
Atelectasis or PNA from displacement of
diaphragm
Protein loss during times of increased
peritoneal permeability
63. Nursing Considerations for Dialysis
Daily weights to track fluid status. Pt should know his “dry” weight
Be SURE patient had an AM weight on day of his run, and obtain a post weight
upon return
Vital signs- hyper/hypotension, fever indicating infection
Never take BP ______________!!
Assess lungs for crackles, heart for dysrhythmias
Assess access site. In PD, look for redness, swelling, and drainage. In HD,
look for redness, warmth, oozing. Listen to bruit, assess distal pulse, feel the
thrill. Patient should have no pain at access site
If your HD pt has an arterial access catheter instead of AV graft, assess site for
redness, swelling, drainage, pain. Do not use for giving meds/fluids, do not flush
with saline (unless your facility has a protocol that allows you to)
64. Nursing Considerations for Dialysis
Know pre-dialysis labs, anticipate which labs might be corrected by
dialysis and which won’t (i.e. dialysis will correct hyperK+ but not
anemia)
Make sure labs are NOT drawn from the arm with the AV fistula!
Scheduled medications: some may need to be held before HD
Antihypertensive meds should be held, as drop in BP is expected
Antiarrhythmics may be given
Drugs likely to be “eaten” by the dialysis process such as water soluble
vitamins should be held
Held drugs can be administered 2-4 hours after run is complete, if patient
is stable
65. Keep an Eye on Your Orders!
Practitioners will add labs all the
time
Then replacements
Then more labs
Then more replacements
Then….
67. Transplantation Basics
It works! 90-95% of all transplants have > 1 year survival rate
But, fewer than 4% of ESKD patients will receive a transplant. The wait for
a deceased donor (about 73% of all transplants) averages 2-5 years
Must be approved to become a recipient, and then get on the list.
Criteria vary by transplant center
Kidneys are matched by ABO group and HLA typing, age, length of
wait, number of antibodies, and location
The donor kidney may be removed laparoscopically or open surgery
Recipient will be opened from iliac crest to pubis symphysis. Usually,
old kidney is just left in place, with key vascularization transferred to
the new kidney
68. Post-op Care
Donor may have significant pain, emotional response. Can be
discharged 2-5 days post-op
Recipient may still need dialysis for a few days until new kidney
becomes functional
Careful fluid and electrolyte management, making sure kidney has
adequate perfusion and fluids
Foley catheter for accurate I/Os and to assess for clots in bladder. If
urine output drops suddenly, check Foley for a clot in tubing
ATN (a potentially reversible form of intrinsic renal failure) may
develop, dialysis will be needed for possibly a period of weeks
69. Post-transplant Care
Immunosuppressive therapy to decrease risk of rejection
Frequent monitoring for long-term risks/complication
Rejection
Infection
CV disease (Immunosuppressants can worsen HTN and dyslipidemia)
Cancers are more prevalent in transplant patients, likely because of the effects of
the immunosuppressants. Common types are basal and squamous cell carcinoma
of the skin, Hodgkin’s and non-Hodgkin’s lymphoma, and Kaposi sarcoma
Recurrence of original kidney disease
Corticosteroid related complications: necrosis of hip and knee joints, peptic ulcer
disease, glucose intolerance, cataracts, infections, and malignancies
70. Ethical Concerns with Transplant
Organ procurement
Coercion or payment of a familiar live donor.
Foreign travel to an unfamiliar live donor.
Black Market
Criteria for being on the list
No smoking/alcohol/drug abuse
Morbid obesity
Previous non-compliance with treatment plan
Principles of social justice and healthcare ethics:
Community and the common good (stewardship), human dignity
Autonomy, beneficence, justice, non-maleficence
71. Transplant Ethics Case Study
Handout 3
Discuss your initial reaction, did that change as you read the study?
What information causes indecisiveness for you?
Can an adolescent be held accountable for his own healthcare?
In this case, what principles does autonomy conflict with?
72. What the Author of the Case Study Concluded:
“It would be inappropriate to give a teenager a kidney if the odds of graft survival
were low. This would not only be a poor allocation of scarce resources, it would also
be dangerous for the teen, as noted above. It would be equally inappropriate to deny
a teenager access to a transplant simply because he was judged on the basis of age to
be at high risk for nonadherence.
The best approach in this situation is to make an individualized assessment of the
barriers to adherence, the likelihood of nonadherence, and the potential benefits of
interventions that might improve adherence. In this case, since the patient is already
on dialysis, his ability to adhere to the demands of that regimen might be considered
a “trial of therapy” that will give information about the likelihood that he would
adhere to posttransplant treatment. He should be given clear instructions about what
is expected of him, feedback whether or not he adheres to the demands of dialysis,
and an endpoint to this “trial of therapy.” If he is able take medication, manage his
diet and fluids, and keep his appointments in clinic and in dialysis, then he should
be eligible for a second transplant.”
Do you agree? Additional thoughts?
Can lose up to 90% renal function. More common in women.
12x per hour. (Assuming a blood volume of ~5L) Less than 1%, about 1-2 liters/day. 22%
Yes, medulla is misspelled here. But it was the prettiest image I found. So I went with it.
This is why the nephron is so important.
Proximal/distal convoluted tubule
135-145
3.5-5
8.5-10.2
2.4-4.5
22-29
7.35-7.45
BUN- urea nitrogen is a waste product that is the end result of protein metabolism, but can be variable depending on diet, stress, inflammation, hydration levels, and is not specific for kidney function
Creatinine- the byproduct of normal muscle function and is produced at a fairly consistent rate in the body
Angiotensin-converting Enzyme inhibitors: Angiotensin II causes vasoconstriction. Less pressure on the glomeruli. SE are cough- related to accumulation of bradykinin (other name for ACE), hyperkalemia if on supplements or k+ sparing diuretic. Contraindicated in renal stenosis, as AngioII actually helps protect glomuli in that case by constricting the efferent arteriole. Angioedema- an acute reaction that causes capillary permeability and swelling of the tongue, glottis, lips, pharynx. Again, bradykinin.
Angiotensin II Receptor Blockers; SE: angioedema, contraindicated in renal stenosis patients.
Spironolactone can produce gynecomastia, menstrual irregularities, impotence, hirsutism, and deepening of the voice. Because similar structure to steroid hormones such as progesterone, estradiol, testosterone.
Furosemide- dehydration, hypotension, hypokalemia. Vitals, I/Os, assisting with getting up, not giving to a walkie-talkie late in the evening, safety concerns at home, do they take it or do they not like to pee?
Clumped together because they produce the same results- blood or urine can’t get where it needs to go.
Technically not obstructive or vascular, but hereditary kidney disease. On autopsy, it looks as though the kidney is filled with golf balls. Childhood CKD is usually rapidly progressing, 30-50% of newborns with PKD will die shortly after birth. If survives to 1st birthday, chances of survival increase, but about 1/3 will go on to need dialysis or transplant by age 10.
Moving onto infections/inflammatory disorders…
My friend went to Africa… so that was the only time I’ve ever had pyelo…Oops, I mean…. costovertebral angle
Note the two abbreviations, used interchangeably in texts..and probably even in this presentation, depending on which book I was looking at
Medications matter?
Acute or Chronic? Trick question- treating as acute, but will need follow up to make sure kidney health is retained. If concerned today, get labs- especially Cr and BUN to compare to later tests.
E. Coli sensitive to: Ciprofloxacin, fluoroquinolone.
Low dose continuous ABX, intermittent self-treatment- Macrobid- poorly metabolized/absorbed, so excreted in urine where it hangs out in the bladder to kill organisms before they become more complicated.
, Something with the product of the antibody-antigen process, these settle in the glomeruli.
Do we need a urine culture? Expect to see large numbers of erythrocytes and erythrocyte casts-
Lack of fever would make pyelo less likely
Why are both fluid and sodium restricted? If they are fluid up- why not give salt?
Decreased renal blood flow such as a thrombus in the renal artery
Nephrotoxic drugs: antibiotics (such as tetracycline, sulfa), CT contrast with iodine, heavy metals such as lead, barium, and iron. NSAIDs such as ASA, Ibup, indomethacin
Less than 400ml/day Trauma to cells pushes potassium out
This sounds like good news, but can be deadly if electrolytes are not carefully monitored/corrected
But you can lose up to 75% of your kidney without even knowing it!
CRRT differs from dialysis because is continuous, causes less hemodynamic instability, fluids and electrolytes can be changed/replaced/removed over days instead of hours.
Fluid restriction. Pts in oliguria void 400mL or less per day. So a max of 1000ml. Sounds like a lot? A standard bottle of Dasani you would get from a vending machine is 500mL. So two of those. In 24 hours.
Kidney not working efficiently because of low volume/low perfusion. No force to push filtrate through the glomeruli, not enough 02 for full kidney function. Still ok urine, labs aren’t too out of whack because there is nothing wrong with the nephron yet.
Non infectious because of CBC
BUN/Cr = ratio. 21.9 here. Indicative of pre-renal
Fluids! Management of fluid/electrolytes, reversal of causes, prevention of further damage. Admit him? Go through the process- be the house sup
ACE, ARB, Diuretics, Vitamin and mineral supplementation- use only kidney approved- Nephrocaps. Phosphate binding agents to reduce phosphate absorption from the colon. Calcitriol. Epogen, iron supplementation
A note about diet- most renal pts need low sodium low phos, and low potassium, and low protein. If diabetic- what’s left? No carbs!
Lean meats, used sparingly, other fruits and vegetables not on this list, rice, couscous, corn, tofu if not
Reminder to tell story about the one time I had to leave a pt’s room because of reflex vomiting. Peritoneal dialysis patient with infection.
Start at 0:38 YouTube user Nancy Cerda posted this because “I wanted to share this, because this is my every other day life. Having kidneys that don't work sucks. So spread awareness of kidney failure! You don't want to go threw this every other day. Also, be a kidney donor, because you don't know how bad we want our life back”
Acute tubular necrosis
Should this be illegal?
Black market- human trafficking, murders,
Beneficence. Is transplant the best option? If it fails, he’ll be worse than before. Dialysis would buy him more time to mature, but Non-malfiecence- it does harm him to stay on dialysis longer. Justice- is it just that he would get a 2nd chance where there thousands of others on the waiting list, where he will be given priority because of his age? The others may never get a kidney.
