A nurse is assessing a client who has hypermagnesemia.
Which of the following medications should the nurse prepare to administer?

This is because fever is a common sign of an acute infusion reaction that can occur when receiving IV amphotericin B. An acute infusion reaction is caused by the release of pro-inflammatory cytokines from the fungal cell wall disruption by amphotericin B. It usually occurs within the first hour of infusion and can be prevented by administering pre-medications such as antipyretics, antihistamines, or corticosteroids.

Choice A. Pedal edema is wrong because it is not a typical sign of an acute infusion reaction.

Pedal edema may indicate fluid overload, heart failure, or renal impairment, which are not directly related to amphotericin B infusion.

Choice C. Dry cough is wrong because it is not a typical sign of an acute infusion reaction.

Dry cough may indicate an allergic reaction, pulmonary infection, or interstitial lung disease, which are not directly related to amphotericin B infusion. Choice D. Hyperglycemia is wrong because it is not a typical sign of an acute infusion reaction.

Hyperglycemia may indicate diabetes mellitus, steroid use, or stress response, which are not directly related to amphotericin B infusion.

Furosemide is a diuretic that is used to treat heart failure by reducing fluid retention and lowering blood pressure. It can cause some side effects, such as increased urination, thirst, dry mouth, headache, dizziness, nausea, and electrolyte imbalance.

Choice A is wrong because BUN (blood urea nitrogen) is a measure of kidney function and a normal range is 7 to 20 mg/dL.

A BUN of 15 mg/dL is not a cause for concern and does not indicate any adverse effect of furosemide.

Choice C is wrong because potassium is an electrolyte that is important for nerve and muscle function and a normal range is 3.5 to 5.0 mEq/L.

Potassium of 3.8 mEq/L is within the normal range and does not indicate any adverse effect of furosemide. However, furosemide can cause low potassium levels (hypokalemia) in some cases, so the nurse should monitor the client’s potassium levels regularly and advise the client to eat foods rich in potassium, such as bananas, oranges, and potatoes.

Choice D is wrong because dizziness upon standing is a common side effect of furosemide and does not require immediate notification of the provider. However, the nurse should instruct the client to rise slowly from a sitting or lying position to prevent falls and to drink enough fluids to prevent dehydration.

Choice B is correct because difficulty hearing or hearing loss is a rare but serious side effect of furosemide that may indicate ototoxicity (damage to the inner ear). This can be irreversible if not treated promptly and may affect the client’s quality of life and safety. The nurse should notify the provider immediately if the client reports difficulty hearing or any other signs of ototoxicity, such as ringing in the ears (tinnitus) or vertigo (a sensation of spinning). The provider may need to adjust the dose of furosemide or switch to another diuretic that is less ototoxic.
