Which adverse effects associated with furosemide should the nurse be aware of?

Furosemide, a loop diuretic, is commonly prescribed to reduce fluid overload in various conditions such as heart failure or renal impairment. Understanding the potential adverse effects of this medication is crucial for effective patient monitoring and care.

The correct choice highlights tinnitus, hypotension, and hypokalemia as significant adverse effects associated with furosemide use. Tinnitus can occur due to the ototoxicity associated with high doses or rapid intravenous administration; this is particularly important in vulnerable populations, such as those also taking aminoglycosides. Hypotension may result from the diuretic's effectiveness in reducing blood volume, which lowers blood pressure. Hypokalemia, or low potassium levels, is a particularly critical consideration because furosemide increases potassium excretion through the kidneys, potentially leading to dangerous cardiac issues if not managed appropriately.

Knowing these risks allows a nurse to monitor the patient's blood pressure and electrolyte levels vigilantly, ensuring timely interventions if adverse effects arise. Overall, being aware of these potential complications enhances patient safety and the effectiveness of the treatment plan.
