Which of the following effects is NOT a side effect of Furosemide?

Furosemide, a loop diuretic, is known for its ability to remove excess fluid from the body by inhibiting sodium and chloride reabsorption in the kidneys. One of the key aspects of furosemide's pharmacological profile is its impact on potassium levels.

The correct answer indicates that hyperkalemia, which refers to elevated potassium levels in the blood, is not a side effect of furosemide. In fact, furosemide typically causes the opposite effect, leading to hypokalemia, or low potassium levels. This is because the increased excretion of sodium and water through the urine can also lead to a corresponding loss of potassium.

In contrast, ototoxicity and nephrotoxicity are recognized side effects of furosemide. Ototoxicity may manifest as hearing issues due to the drug's effects on the inner ear, especially when administered in high doses or combined with other ototoxic agents. Nephrotoxicity can occur in certain circumstances, particularly if furosemide is used inappropriately or in patients with pre-existing kidney issues.

Understanding these effects is crucial when administering furosemide, particularly in monitoring for signs of electrolyte imbalances and ensuring patient safety. Thus
