Furosemide (Lasix) is a loop diuretic that works by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased excretion of these electrolytes along with water. This diuretic can also lead to significant potassium loss, resulting in hypokalemia, which can cause muscle weakness, cramps, and cardiac arrhythmias. Monitoring potassium levels is crucial in patients on furosemide to prevent these complications. Hyperkalemia, hypernatremia, and hypocalcemia are less common concerns with this medication.

Study Tip:

For patients on diuretics, monitor potassium levels regularly to avoid hyperkalemia or hypokalemia, depending on whether the diuretic is potassium-sparing (e.g., spironolactone) or potassium-wasting (e.g., furosemide or hydrochlorothiazide).
