A nurse is administering gentamicin by intravenous (IV) route at 0900. The medication will take 60 minutes to infuse. When should the nurse obtain a blood sample for a peak blood level of gentamicin?
1130
1100
1000
1030
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.
