It also discusses how the kidneys regulate water and electrolyte balance, as well as pH balance, through processes like selective reabsorption and secretion and hormones like antidiuretic hormone and aldosterone. The kidneys play an important role in maintaining homeostasis by precisely regulating the composition and volume of urine.
Here are the key steps in approaching hypokalemia:
1. Determine if the hypokalemia is caused by redistribution or depletion. Redistribution occurs with insulin, beta-agonists, alkalosis etc. and replacement may cause overshoot hyperkalemia. Depletion is more common, due to GI losses, diuretics, medications etc.
2. Estimate the potassium deficit based on how low the serum potassium is. A deficit of 100-250 mEq is suggested for levels of 3.5-3 mEq/L.
3. Choose oral replacement whenever possible over IV, as oral is safer and better tolerated. Only use IV if patient cannot take oral or deficit is severe.

Fluids and electrolytes are essential for normal body function. Electrolytes like sodium, potassium, chloride, and bicarbonate help regulate fluid balance and pH. There are three main fluid compartments - intracellular, interstitial, and intravascular. Fluids can shift between compartments through processes like diffusion, osmosis, and active transport. Imbalances can cause edema. Monitoring for edema, vital signs, and lab values is important to assess fluid status and guide treatment like fluid resuscitation.
The document summarizes key concepts about fluid, electrolyte, and acid-base homeostasis. It discusses how the kidneys regulate water and salt composition between body compartments. Three hormones - aldosterone, atrial natriuretic peptide, and angiotensin II - regulate sodium and chloride balance. The kidneys and lungs work to maintain acid-base balance in the blood through buffering, ventilation, and excretion of acids and bases. Imbalances like respiratory acidosis and metabolic alkalosis can occur if these regulatory mechanisms are disrupted.

This document describes the structure and function of the renal and urologic systems. It details the structures of the kidney including the nephron, which is the functional unit. It explains glomerular filtration and the countercurrent exchange system which allows concentration of urine. Renal blood flow, hormone production, and tests of renal function such as clearance tests and urinalysis are also summarized. The effects of aging on renal function are described.
The document discusses excretion in animals and plants. It describes the process of excretion and the major waste products excreted, such as carbon dioxide, urea, and bile pigments. It also outlines the key excretory organs in mammals, including the lungs, kidneys, skin, and liver. The kidneys play an important role in homeostasis by removing nitrogenous wastes like urea from the blood and regulating water and salt concentrations. The basic unit of the kidney is the nephron, where blood is filtered to form urine and allow for reabsorption of useful substances and removal of wastes.

1 - look at pH\n2 - look at pCO2. (see it as bicarb on chem 7) See if it is metabolic or respiratory. If outside of normal, than it is not \nthe lung’s fault.\n3 - Ex:(Acid)If pCO2 is normal, then it is acute metab. If decreased, then chronic. \n4 - Look at ion gap: Na - (CO2 + Cl) = ion gap. 10-12 = normal. \n Normal, means loss. \n Gap = DKA, LA, ingestion of antifreeze, methanol, aspirin OD, RF, \n If pCO2 elevated, its the lung. Then look at bicarb, see if acute or chronic, see if the kidneys have kicked in.\n*** do the same on the basic side. \n
