Question

based on the blood culture and sensitivity results, the healthcare provider prescribes an iv aminoglycoside antibiotic and discontinues the current prescription for another broad - spectrum antibiotic. the medication administration record indicates that the client received the broad - spectrum antibiotic two hours ago. which action should the nurse implement?
obtain peak and trough serum levels so the aminoglycoside antibiotic can be initiated.
administer the initial dose of the aminoglycoside antibiotic as soon as possible.
withhold antibiotic administration until the healthcare provider clarifies the prescriptions.
schedule the initial dose of the aminoglycoside antibiotic for the following day.

Explanation:

Aminoglycoside antibiotics require peak and trough serum level monitoring to ensure therapeutic levels and avoid toxicity, especially when a previous antibiotic was given recently. Option A is correct as obtaining these levels is necessary before initiating the aminoglycoside. Option B is incorrect as starting the aminoglycoside without monitoring could be unsafe. Option C is unnecessary as the provider’s prescription is clear. Option D is incorrect as delaying the dose without reason isn’t appropriate.

Answer:

A. Obtain peak and trough serum levels so the aminoglycoside antibiotic can be initiated.
