A nurse is caring for a client who has a fungal infection and is given a new prescription for amphotericin B. Which of the following laboratory values should the nurse report to the provider before initiating the medication?

Potassium 5.0 mEq/L (3.5-5.0)

Glucose 120 mg/dL (70-110)

Sodium 140 mEq/L (135-145)

BUN 55 mg/dL (6-24)

Answer and Explanation

The Correct Answer is D

BUN stands for Blood Urea Nitrogen, and it is a laboratory test that measures the amount of nitrogen in the blood that comes from urea, which is a waste product of protein metabolism. Elevated BUN levels indicate impaired kidney function. Amphotericin B is known to be potentially nephrotoxic, which means that it can cause damage to the kidneys. Therefore, the nurse should report an elevated BUN level to the provider before initiating the medication to ensure the safety of the client. Potassium, glucose, and sodium levels are within normal range and do not require intervention in this scenario.

Correct Answer is B

Explanation

The correct answer is choiceb. Monitor the serum medication levels.

Choice A rationale:

Administering gentamicin with food is not necessary and does not minimize the risk of adverse effects. Gentamicin is typically given intravenously or intramuscularly, and food does not impact its administration or absorption.

Choice B rationale:

Monitoring the serum medication levels is crucial when administering gentamicin. Gentamicin has a narrow therapeutic index, meaning the difference between a therapeutic dose and a toxic dose is small. Regular monitoring helps ensure the drug remains within the safe and effective range, reducing the risk of nephrotoxicity and ototoxicity.

Choice C rationale:

Limiting the client’s fluid intake is not recommended. Adequate hydration is important to help prevent nephrotoxicity, a known adverse effect of gentamicin. Ensuring the client has sufficient fluid intake can help protect kidney function.

Choice D rationale:

Instructing the client to report agitation is not directly related to minimizing the risk of adverse effects of gentamicin. While it is important for clients to report any unusual symptoms, agitation is not a common adverse effect of gentamicin. Monitoring for signs of nephrotoxicity (e.g., decreased urine output) and ototoxicity (e.g., hearing loss, tinnitus) is more relevant.

A. Ask the client to look down when instilling the solution. B. Instil the drops into the superior canthus. C. Approach the client’s eye from below it. D. Hold the ophthalmic solution 2 cm (3/4 inch) above the lower conjunctival sac.

Correct Answer is D

Explanation

When administering ophthalmic drops, the nurse should hold the dropper 2 cm (3/4 inch) above the lower conjunctival sac and instill the prescribed number of drops into the sac. The client should be instructed to look up and away from the dropper while the drops are being instilled.
