Question 1 of 5
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?
Correct Answer: A
Rationale: The correct answer is A (1630 and 1930). Peak level is drawn 30 minutes after the medication is infused, which would be around 1630. Trough level is drawn just before the next dose, which is at 1930.
Choice B (1100 and 1700) is incorrect because 1100 is too early for peak level and 1700 is too early for trough level.
Choice C (1400 and 2200) is incorrect because the trough level should be drawn before the next dose at 1800, not at 2200.
Choice D (1745 and 1830) is incorrect because the trough level should be drawn just before the next dose, not 15 minutes before.
