A nurse is caring for a client who is receiving an IV medication and has a prescription for peak and trough blood levels with the next dose scheduled for 1800. The nurse should expect the lab to draw blood samples at which of the following times?

1630 and 1930

1100 and 1700

1400 and 2200

1745 and 1830

Answer and Explanation

The Correct Answer is A

A. 1630 and 1930: Peak and trough levels are used to monitor drug effectiveness and prevent toxicity. Trough levels (lowest drug concentration) are drawn right before the next dose-1745 would be slightly too late. Peak levels (highest drug concentration) are drawn 30-60 minutes after administration (for IV drugs). Since the next dose is at 1800, the trough should be drawn just before the dose (1630) and the peak should be drawn 30-60 minutes after the dose (1930).

B. 1100 and 1700- Incorrect timing, not close to dose administration.

C. 1400 and 2200- Too far from the scheduled 1800 dose.

D. 1745 and 1830- Trough is too close to administration, peak is too early.
