Study Notes
Electrolytes in Extracellular Fluid
- Major cation in extracellular fluid: Sodium (Na⁺)
- Major anion in extracellular fluid: Chloride (Cl⁻)
Hormones and Fluid Regulation
- Aldosterone excess can cause hypernatremia (high sodium) and hypokalemia (low potassium).
- Antidiuretic hormone (ADH) regulates water reabsorption in kidneys, promoting water retention.
Sodium Levels and Hyponatremia
- Normal serum sodium concentration in adults: 135-145 mEq/L.
- Hyponatremia (low sodium) can occur in conditions such as congestive heart failure or excessive water intake.
Potassium Levels and Acidosis
- Common cause of hyperkalemia (high potassium): Kidney failure or excess potassium intake.
- Metabolic acidosis leads to increased potassium levels in the blood due to cellular shifts.
Intracellular Cations
- Major intracellular cation: Potassium (K⁺)
- Distinct from extracellular fluid, where sodium predominates.
Fluid Imbalance Conditions
- Conditions characterized by excess isotonic fluid in extracellular compartment: Hypervolemia or fluid overload.
- Decreased total body water may occur in dehydration or insufficient fluid intake.
