1100

1000

1030

Answer and Explanation

The Correct Answer is D

A. Incorrect: 1130 is too late for an accurate peak level.

B. Incorrect: 1100 is later than necessary for a peak level.

C. Incorrect: 1000 is when the infusion ends, but the drug has not yet reached peak levels in the blood.

D. Correct: Gentamicin peak levels are typically measured 30 minutes after the infusion is completed. Since the infusion starts at 0900 and runs for 60 minutes (until 1000), the peak level should be drawn at 1030.
