    Study Notes

    Causes of Hyperkalemia

    • ACE inhibitors, potassium-sparing diuretics, and NSAIDs can cause hyperkalemia
    • Adrenal insufficiency, rhabdomyolysis, and tumor lysis syndrome can also lead to hyperkalemia
    • Electrolyte imbalance, acid-base disorders, and red blood cell transfusions can cause hyperkalemia

    Treatment of Hyperkalemia

    • Calcium gluconate, insulin, and beta-adrenergic agonists are potential treatments for hyperkalemia
    • Hemodialysis or hemofiltration may be necessary in severe cases

    Causes of Hypokalemia

    • Diuretics, such as loop diuretics and thiazide diuretics, can cause hypokalemia
    • Vomiting, diarrhea, and malabsorption can lead to hypokalemia
    • Hormonal disorders, such as hyperaldosteronism, and certain medications can cause hypokalemia

    Consequences of Hypokalemia

    • Hypokalemia can increase the risk of digoxin toxicity in patients receiving digoxin therapy
    • Arrhythmias and cardiac arrest can occur due to hypokalemia

    Role of Potassium in the Body

    • Potassium is essential for maintaining normal muscle and nerve function
    • It helps regulate heart rhythm and blood pressure
    • Potassium plays a crucial role in maintaining electrolyte balance and acid-base balance
