    Study Notes

    Electrolyte Imbalances

    • Dehydration leads to increased osmolality affecting intracellular phosphate levels.
    • Low sodium (Na) intake or loss results in symptoms such as thirst and weight gain.
    • Increased blood pressure (BP) and cerebral edema are common in dehydration.
    • Hyperactive reflexes and bounding pulse coupled with confusion can indicate severe electrolyte fluctuations.

    Potassium (K) Levels

    • Normal potassium levels range from 3.7 to 5.0 mmol/L.
    • Skeletal muscle weakness and neuromuscular excitability decrease in cases of hypokalemia.
    • Hyperkalemia, characterized by rare renal excretion, can lead to muscle weakness, nausea, and impaired renal function.

    Calcium (Ca²⁺) Levels

    • Normal calcium levels range from 8.4 to 10.6 mg/dL.
    • Low parathyroid hormone (PTH) and vitamin D can lead to hypocalcemia, increasing neuromuscular excitability.
    • Symptoms of hypocalcemia include fatigue, spasms, cramping, tingling, and potential cardiac issues.

    Fluid Accumulation

    • Localized or generalized edema may occur due to increased capillary permeability, infections, or injuries.
    • Conditions causing edema include heart failure and kidney disease affecting fluid retention and distribution.

    Respiratory Regulation of pH

    • Conditions like COPD and pneumonia can lead to respiratory acidosis, indicated by a pH less than 7.35.
    • In respiratory alkalosis, the pH is greater than 7.45, affecting the body's acid-base balance.
    • Increased ventilation helps remove CO2 thus correcting low pH by reducing acidity.

    Urine pH Regulation

    • Urine acidity or alkalinity is controlled through the secretion of H⁺ or reabsorption of bicarbonate.
    • Acidic urine leads to the excretion of H⁺ ions, while alkaline urine involves the retention of CO2 to increase acid levels.
