Question 1 of 5
A nurse is caring for a client who has an infection and a prescription for gentamicin Intermittent IV bolus every 8 hr. A peak and trough are required with the next dose. Which of the following actions should the nurse take to obtain an accurate gentamicin serum level?
Correct Answer: B
Rationale: The correct answer is B. Drawing a trough level immediately before administering the medication ensures the lowest concentration of the drug in the client's bloodstream, providing an accurate baseline. Drawing a peak level 30 minutes after the dose allows the nurse to measure the highest concentration of the drug, which indicates how well the body metabolizes and eliminates the medication. This timing ensures accurate assessment of both peak and trough levels for monitoring gentamicin therapeutic levels. Option A is incorrect because drawing a peak level before the medication administration can result in a falsely elevated level due to the drug being freshly administered. Option C is incorrect as the timing is not aligned with the medication administration schedule, leading to inaccurate results.
