What should a nurse assess for prior to administering furosemide?

Assessing for allergies to sulfonamides is crucial prior to administering furosemide, particularly for patients who may have a known allergy to sulfa drugs. Furosemide, a loop diuretic, is a sulfonamide derivative, and patients with a sulfonamide allergy may be at risk for adverse reactions if furosemide is administered. Identifying this allergy can prevent potentially serious allergic reactions, which may include skin rash, hives, or more severe responses like anaphylaxis.

While evaluating current blood pressure status, history of kidney disease, and signs of dehydration are also important considerations when administering furosemide, the presence of a sulfonamide allergy directly pertains to the safety and tolerance of the medication for the individual patient. Prioritizing the assessment of allergies helps ensure patient safety and proper efficacy of treatment.
