it explain about definition of fluid and electrolyte disturbance, causes and different types of fluid disturbance. diagnostic evaluation and their emergent management along with supportive management.
2. GENERAL OBJECTIVE:
At the end of the presentation the group
will be able to know about the topic Fluid
and Electrolyte Imbalance and can utilize
that knowledge in clinical settings.
3. ELECTROLYTE
Electrolytes are minerals in blood and other body fluids that
carry an electric charge. Electrolytes affect the amount of water
in body, the acidity of blood (pH) muscle function, and other
important processes.
Common electrolytes include:
Chloride
Magnesium
Phosphorous
Potassium
Sodium
Electrolytes can be acids, bases, and salts.
4. MINERALS:
“A mineral is an element or chemical compound
that is normally crystalline and that has been
formed as a result of geological processes” (Nickel,
E. H., 1995).
“Minerals are naturally-occurring inorganic
substances with a definite and predictable chemical
composition and physical properties.” (O'
Donoghue, 1990).
5. Fluid Balance
Fluid balance is the concept of human homeostasis .
Body fluids are mainly located in two compartments of body
i.e. intracellular and extracellular spaces.
1 Intracellular spaces- ( Fluid within cells)
2 Extracellular spaces- ( fluid outside cells) It is further divided
into three-
Intravascular spaces- (fluid within blood vessels)
Interstitial spaces- (Fluid present in interstitial spaces that
surrounds the cell).
Transcellular spaces- It contains approximately 1L of fluid.eg.
CSF

8. FLUID VOLUME DEFICIT (HYPOVOLEMIA)
The state in which an individual experiences
vascular, cellular, or intracellular dehydration-
According to NANDA.
Fluid volume deficit or hypovolemia, occurs
from a loss of body fluid or the shift of fluids
into the third space or from a reduced fluid
intake.
9. FLUID VOLUME EXCESS
(HYPERVOLEMIA)
The state in which an individual experiences
increased fluid retention and edema -
According to NANDA
Fluid volume excess or hypervolemia, occurs
from an increase in total body sodium content
and an increase in total body fluid volume.
10. Fluid Volume Disturbances
1.Fluid Volume Deficit (Hypovolemia)- Fluid volume deficit(FVD)
occurs when loss of extracellular fluid volume exceeds the
intake of fluid.
Etiology-
decreased fluid intake.
vomiting, diarrhea
may occur after blood donation
Trauma
Risk factors include diabetes insipidus, adrenal insufficiency,
osmotic diuresis, hemorrhage and coma.
12. Moderate deficit Severe deficit
Skin Flushed, dry Cold, Clammy
Mouth Dry mucus membrane Dry, cracked tongue
Eyes Soft, sunken eyeballs
Cardiovascular Tachycardia, Hypotension
CNS Apprehension, restlessness Lethargy, coma
Blood Increased hematocrit, BUN
and electrolytes
Urine High specific gravity, Oliguria, concentrated
Scanty amount urine
Other Thirst, weight loss Thirst, weight loss and
fever
13. Assessment and Diagnostic Finding
History and physical examination
Laboratory tests include assessment of BUN and serum
creatinine concentration
Hematocrit levels
Serum electrolyte changes also occur-
Hypokalemia occurs with GI and renal losses.
Hyperkalemia occurs with adrenal insufficiency
Hyponatremia occurs with increased thirst and ADH release.
Hypernatremia results from increased insensible losses and
diabetes insipidus.
15. Medical Management
Oral fluids that include moderate sugars
and electrolytes are needed to replenish depleted
sodium ions.
Emergency oxygen should be immediately
employed to increase the efficiency of the patient's
remaining blood supply
Isotonic electrolyte solutions eg. Lactated Ringer’s
or 0.9 % sodium chloride) are frequently used to
treat the hypotensive patient
Blood transfusions
16. Nursing Management
Record intake and output
Monitor body weight
Monitor vital signs

Assess the cardiovascular functions
Preventing FVD
Correcting FVD
17. Fluid Volume Excess ( Hypervolemia)
It refers to an isotonic expansion of the ECF caused by
the abnormal retention of water and sodium in
approximately the same proportion in which they
normally exist in the ECF.
Etiology-
-heart failure, renal failure and cirrhosis of liver.
-excessive amount of table salt may lead to increase
in total body water
-Excessive intake of fluids
-Excessive administration of I.V. fluids.
-Long term use of corticosteroids.
19. Assessment and Diagnostic Findings
History and physical examination
Laboratory test include assessment of BUN and
hematocrit levels. Both of these values may be
decreased because of plasma dilution.
Chest X-rays can be done to reveal pulmonary
congestion
21. Medical Management
excessive administration of sodium containing fluids,
discontinue the infusion.
Pharmacologic therapy- Diuretics are prescribed
when dietary restriction of sodium alone is
insufficient to reduce edema
When pharmacological agents cannot act efficiently
in case of renal impairement, Hemodialysis or
peritoneal dialysis may be used to remove
nitrogenous wastes.
In diet, sodium restriction should be done.
22. Nursing Management
Record intake and output
Monitor body weight
Assess the breath sounds
Monitor the skin condition

23. ELECTROLYTES IN BODY FLUIDS
ELECTROLYTE: A substance that is dissolved in solution and
some of its molecules spilt or dissociate into electrically
charged atoms or ions. The ions formed when electrolytes
dissolve and dissociate serve four general functions in the
body.
control the osmosis of water between fluid compartments
maintain the acid base balance
production of action potentials and graded potentials
serve as cofactors needed for optimal activity of enzymes
24. 1.SODIUM
Sodium is the abundant electrolyte in the ECF,
accounting for 90% of the extracellular catoins. Its
normal blood Na+ concentration is 136 to 148 mEq/L.
Sodium has a major role in controlling water
distribution throughout the body
The most common sodium imbalances are
sodium deficit and sodium excess.
25. HYPONATERMIA
Hyponatremia is a sodium deficit or serum sodium level of less
than 135 mEq/L.
1. Increased sodium excretion
Excessive diaphoresis
Diuretics
Renal disease
2. Inadequate sodium intake

28. MEDICAL MANGEMENT
IV saline for patient who have hyponatremia without
fluid overload. Isotonic (0.9 percent), hypertonic (3
percent).
For fluid overload , diuretics restrictions to a total of
800ml in 24 hrs
Such as lithium and declomycin these are
antagonize anti diuretic hormone may be
administered
29. NURSING MANAGEMENT

cerebral, renal and gastrointestinal status
Instruct the client to increase oral sodium intake
If the client is taking lithium monitor lithium level
maintain intake and output chart
assesses for signs of circulatory overload e.g. cough,
dyspnea, puffy eyelids, weight gain in 24hrs.
lungs should be auscultated for crackles
30. HYPERNATREMIA
Hypernatremia is excess sodium in ECF or
serum sodium of greater than 145 mEq/L.
because the osmotic pressure of extra cellular
fluid is increased.
31. CAUSES
Decreased sodium excretion
• Renal failure
• Corticosteroids
Increased sodium intake
• excessive oral sodium ingestion
• excessive administration of sodium containing IV fluids
Increased water loss
• excessive diaphoresis
• watery diarrhoea
34. MEDICAL MANAGEMENT
Infusion of a hypotonic electrolyte solution
e.g. 0.3% sodium chloride or dextrose 5% in
water in indicated when water needs to be
replaced without sodium
Diuretic- Lasix
If kidneys are not functioning then dialysis
should be performed
35. NURSING MANAGEMENT
Dietary history of
the patient
Physical
examination
Restrict sodium
intake
Daily weight should
be monitored
intake and out put
chart of the patient
monitor the
changes in behavior
36. 2.POTASSIUM
It is the major intracellular electrolyte, 98% of
the body’s potassium is inside the cell. The
remaining 2% in the ECF and is important in
neuromuscular functions. The normal serum
potassium concentration ranges from 3.5 to 5.0
mEq/L.
37. HYPOKALEMIA
HYPOKALEMIA is a potassium deficit or a serum
potassium level of less than 3.5mEq/L.
CAUSES
Actual total body potassium loss
Inadequate potassium intake
Dilution of serum potassium
Water intoxication
Intravenous therapy with potassium poor solution
40. MEDICAL MANAGEMENT
provide the food high in potassium
the adult recommended allowance for potassium is
1875 to 5625mg/day
oral potassium therapy for mild hypokalemia( 3.3 to
3.5mEq/l)
Severe hypokalemia require IV intervention. A
clients level with 3 and 3.4 mEq/l needs 100 to
200mEq of IV potassium for to increase 1mEq/l. if it
is less than 3 then client need 200 to 400 mEq/l
41. NURSING MANAGEMENT
history focus on dietary
intake, conditions for
potassium loss, use of
diuretics
Review the laboratory reports
physical examination
Check vital signs closely
check redial pulse
The nurse should assess renal
function before administering
potassium
Take the precautions with
intravenously administered
potassium
42. HYPERKALEMIA
Hyperkalemia is a serum potassium level that exceeds
5.1mEq/L. It can lead to cardiac arrest.
CAUSES
Excessive
potassium
intake
Decreased
sodium
excretions
Tissue
damage
Acidosis
44. Neuromuscular
• EARLY- muscles twitches, parenthesis
• LATE- Profound weakness, flaccid paralysis in
the arms and legs
Gastrointestinal
• Increased motility, hyperactive bowel sounds
• Diarrhoea
45. MEDICAL MANAGEMENT
If plasma potassium level is less than 5.5 mEq/l restrict the diet
that is rich in potassium
If level is higher the provide the potassium wasting diuretics to
improve urine output.
If hyperkalemia is severe then infusion of IV calcium gluconate
to decrease the effect of potassium excess on the myocardium.
As hyperkalemia increase then sodium polystyrene sulfonate
may be given orally.
In marked renal failure peritoneal dialysis or hemodialysis may
be needed.
46. NURSING MANAGEMENT
Take the dietary history of the patient.
Check the vital signs bowel functions, urine output, lung
sounds (crackles) and peripheral edema every 4 to 8 hours,
in severe hyperkalcemia performs hourly checks of vital signs
including apical pulse.
Nurse should monitor the cardiovascular, respiratory,
neuromuscular, renal and gastrointestinal status, place on a
cardiac monitor.
ECG changes should be monitored continuously.
Prepare for the IV administration of glucose with regular
insulin to move excess potassium into the cells.
Instruct the client to avoid the use of use salt substitutes or
other potassium containing substance.
47. 3.CALCIUM
99% of the calcium is found in the bones. Its normal
value 8.6 to 10.0mg/dl. The most important
regulator of calcium concentration in blood plasma
is parathyroid hormone (PTH). A low level of
calcium in blood plasma promotes release of more
PTH, which stimulates osteoclasts in bone tissue to
release calcium from bone extracellular matrix.
48. HYPOCALCEMIA
Inhibition of calcium absorption
from the gastrointestinal tract
Increased calcium excretion
Conditions that decrease the
ionized fraction of calcium
51. MEDICAL MANAGEMENT
Provide the calcium gluconate, calcium lactate or calcium
chloride.
Calcium supplement should be given with a glass of milk
with meals. Vitamin D in the milk promotes calcium
absorption.
Mild hypocalcemia can be treated to give the diet high in
calcium like dairy products- cheese, ice cream, milk
IV calcium chloride or calcium gluconate must be given
slowly to avoid hypotension and bradycardia.
Use D5 solutions when dilution is necessary; avoid saline
solutions because they promote calcium loss.
52. NURSING MANAGEMENT
Take the history of the client current and chronic illness, diet intake and
medications, identify the risks for calcium deficit
Monitor cardiovascular, respiratory, neuromuscular and gastrointestinal
status; place the client on cardiac table.
when administering calcium intravenously , warm injection to body
temperature before administering , administer slowly, monitor for
electrocardiogram changes, observe for infiltration monitor for
hypocalcemia
Move the client carefully and monitor for signs of a fracture.
Keep 10% calcium gluconate available for treatment of acute calcium
deficit.
Instruct the client to consume foods high in calcium like cheese, milk and
Soya milk, spinach, low fat etc
53. HYPERCALCEMIA
Hypercalcemia is a total serum calcium level
greater than 10.5 mg/dl, it most often occurs
when calcium is mobilized from the bony
skeleton. It may occur in any age group. It is a
common disorder that can have serious
physical complications.
57. MEDICAL MANAGEMENT
Administer the IV normal saline, rapidly with
furosemide to prevent fluid over load
Administer medications as prescribed that
inhibit calcium reabsorption from the bone
like aspirin, nonsteroidal anti-inflammatory
drugs.
Corticosteroids drugs decrease calcium level
58. NURSING MANAGEMENT
Take the history of the patient and identify the high risk patient.
Assess the vital signs, apical pulses, and ECG every 1 to 8 hours.
Check the bowel sounds, renal function and hydration status should be
assessed every 8 hours.
If flank pain arises, strain all urine to capture renal calculi for analysis.
Report urine output of less than 0.5ml/kg/hr for 2 hours.
Advise the patient to take sodium unless it is contraindicated to promote
calcium loss through the kidneys
Advise the patient to report the clinical manifestation of renal calculi such
as flank pain, hematuria or cardiacdysfunctions
Instruct the client to avoid foods high in calcium like cheese, milk and soy
milk Spinach, low fat.
59. 4.MAGNESIUM
It’s normal value 1.6 to 2.6mg/dl. In adults, about
54% of the total body magnesium is part of
bone matrix as magnesium salts. Magnesium is
a cofactor for certain enzymes needed for the
metabolism of carbohydrates and proteins and
for the sodium-potassium pump.
60. HYPOMAGNESEMIA
Hypomagnesemia Is a serum magnesium level less
than 1.6 mg/dl
CAUSES
Insufficient magnesium intake
Increased magnesium excretion
Intracellular movement of
magnesium
62. MANAGEMENT
Monitor the cardiovascular, gastrointestinal, respiratory, neuromuscular
and central nervous system, place the patient on cardiac monitor
Restore the calcium level because hypocalcemia frequently accompanies
hypomagnesemia
Administer magnesium sulfate by the IV route in severe cases(
intramuscular injections pain and tissue damage) monitor serum
magnesium levels frequently.
Oral preparations of magnesium may cause diarrhea and increase
magnesium loss
Instruct the client to increase the intake of foods that contain magnesium
like cauliflower, green leafy vegetable such as spinach, milk, potatoes
63. HYPERMAGNESEMIA
Hypermagnesemia is a serum magnesium level that
exceeds 2.6 mg/ dl.
CAUSES-
Increased magnesium intake
magnesium – containing antacids and laxatives
excessive administration of magnesium
intravenously
Decreased renal excretion of magnesium as a result
of renal insufficiency
65. MANAGEMENT
Monitor cardiovascular , respiratory, neuromuscular and
central nervous system status, place client on cardiac
monitor
Administer diuretic that are prescribed by physician to
increase renal excretion of magnesium
Intravenously administered calcium chloride or calcium
gluconate may be prescribed to reverse the effects of
magnesium on cardiac muscles
Instruct the client to restrict dietary intake of magnesium
containing foods like cauliflower, green leafy vegetables such
as spinash
Instruct the client to avoid the use of laxatives and antacids
containing magnesium.
66. 5.PHOSPHATE
About 85% of the phosphate in adults is present as
calcium phosphate salts, which are structural
components of bone and teeth. The normal blood
plasma concentration of ionized phosphate is only
1.7mEq/liter .Although some are free, most phosphate
ions are covalently bound to organic molecules such
as lipids, proteins, carbohydrates, nucleic acids, and
adenosine triphosphate(ATP).
67. HYPOPHOSPHATEMIA
The normal value of phosphorus is 2.7 to 4.5mg/dl, when
their amount is less than 2.7mg/dl is called
hypophosphatemia.
CAUSES
Insufficient
phosphorus
intake
Increased
phosphorus
excretion

69. MANAGEMENT
Monitor cardiovascular, respiratory, neuromuscular, central
nervous and hematological status.
Administer phosphorus orally along with a vitamin D
supplement
Administer phosphorus intravenously only when serum
phosphorus level fall below 1 mg/dl and when the client
experience critical clinical manifestation.
Administer phosphorus intravenously slowly because of the
risks associated with hyerphosphatemia
Assess renal system before administering phosphorus
Instruct client to increase intake of phosphorus containing
foods while decreasing the intake of calcium containing
foods like fish, nuts, whole grain breads and cereals.
70. HYPERPHOSPHATEMIA
Hyperphosphatemia is a serum phosphorus level that
exceeds 4.5mg/dl, most body systems tolerating
elevated serum phosphorus level well. An increase in
the serum phosphorus level is accompanied by a
decrease in the serum calcium level.
CAUSES-
Decreased renal excretion resulting from renal insufficiency
Tumor lysis syndrome
Increased intake of phosphorus including dietary intake or
overuse of phosphate containing laxatives or enemas.

80. RESEARCH STUDY
AN EXPERIMENTAL STUDY ON FLUID AND ELECTROLYTE
IMBALANCE AND ITS CORRECTIVE MEASURES AMONG CHILDREN
ABSTRACT OF RESEARCH FINDINGS
Fluid and electrolyte imbalance is most commonly associated with
diarrhea among children (3-5 yr). Among all the disease conditions
encountered in children, diarrhea is the most common causing the
highest morbidity and mortality. Dehydration and acidosis are the
most common cause of death in diarrheic children. The present
study was carried out on 24 children including six clinically healthy
and 18 diarrheic children. Physiological, Hematological, blood
biochemical and electrocardiographic changes were monitored in
control as well as diarrheic children. Efficacy of fluid therapy regimen
i.e. ORS was evaluated in treating fluid and electrolyte imbalance in
diarrheic children during the period of study.
81. CONTI…
RESULTS:
Following the administration of fluid therapy regimen i.e.
ORS, the physiological, (HR, RR) hematological (Hb, PCV
and TEC), plasma biochemical (total protein, glucose,
sodium, potassium, chloride and phosphorus) and
electrocardiographic parameters exhibited a trend towards
restoration to normal by the 3rd to 5th day of treatment.
ORS was found to be more efficacious and rapid in
correcting fluid and electrolyte imbalance in the diarrheic
children.
82. CONCLUSION
The ORS used in the present study, may be recommended for
clinical and field trials for correcting fluid and electrolyte
imbalance in mildly to moderately dehydrated diarrheic
children. A further study needs to be undertaken, on the
combined use of oral and parenteral hypertonic solutions for
treating severe dehydration in children.
