The primary care NP is preparing to prescribe a diuretic for a patient who has heart failure. The patient reports having had an allergic reaction to sulfamethoxazole-trimethoprim (Bactrim) previously. The NP should prescribe

The primary care nurse practitioner (NP) should prescribe a diuretic that does not belong to the sulfonamide class, given the patient’s history of an allergic reaction to sulfamethoxazole-trimethoprim (Bactrim). A suitable option would be furosemide (Lasix), which is a loop diuretic.

Rationale:
Furosemide (Lasix): This is commonly used in patients with heart failure to manage fluid overload and is not a sulfonamide.
Other alternatives, such as bumetanide or torsemide, can also be considered as they are loop diuretics and are effective in managing heart failure.
Key Points:
Always assess the patient’s allergy history before prescribing medications.
Monitor the patient for any potential adverse effects related to diuretic therapy, such as electrolyte imbalances, especially hypokalemia.
Educate the patient about the importance of adherence to the medication regimen and monitoring their symptoms of heart failure.
