What is the primary cation in extracellular fluid? Sodium
What is the primary anion in extracellular fluid? Chloride
What is the primary cation in intracellular fluid? Potassium
What is the primary anion in intracellular fluid? Phosphate
What is the relationship between sodium and potassium? They usually have an inverse relationship; when one increases, the other
decreases.
What is the role of sodium in the body? Maintains extracellular fluid concentration and volume, influences water
distribution, generates nerve impulses, and regulates muscle contractility and
acid-base balance.
What is the normal serum sodium level? 136-145 mEq/L.
, What is the role of potassium in the body? Essential for neuromuscular and cardiac function, glycogen deposition, and acid-
base balance.
What is the normal serum potassium level? 3.5-5.0 mEq/L.
What is the role of calcium in the body? Major cation in bones and teeth, involved in blood clotting, nerve impulse
transmission, and muscle contractions.
What regulates calcium levels in the body? Parathyroid hormone (PTH) and calcitonin.
What is the normal total serum calcium level? 9-10.5 mg/dL.
What is the role of magnesium in the body? Involved in carbohydrate metabolism, protein synthesis, blood glucose control,
muscle contraction and relaxation, and neurotransmitter release.
Where is most magnesium stored in the body? In muscle and bone, with only about 1% in the extracellular space.
What can excessive dietary sodium lead to? Increased risk for hypertension, heart disease, and stroke.
What can high urine output cause regarding potassium? Excessive potassium loss (hypokalemia)
What happens to potassium levels with impaired renal Potassium retention occurs.
function?
What is the relationship between calcium and They usually have an inverse relationship.
phosphate?
What is the relationship between calcium, potassium, and They usually have a similar relationship.
magnesium?
What regulates magnesium levels in the body? The kidneys and GI system
What is the normal serum magnesium level? 1.3-2.1 mEq/L.
