ATI Pharmacology Exam Final Questions

Extract:


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 is required with the next dose. Which of the following actions should the nurse take to obtain an accurate gentamicin serum level?

Correct Answer: A

Rationale: The correct answer is A. Drawing a trough level immediately before administration ensures the lowest concentration of the medication, providing an accurate baseline. Drawing a peak level 30 minutes after the dose allows for the measurement of the highest concentration reached, which is important for evaluating the drug's effectiveness and potential toxicity.


Choice B is incorrect because the timing does not align with the dosing schedule.
Choice C is incorrect as drawing the peak level before administration would not reflect the peak concentration post-administration.
Choice D is incorrect as the trough level should be drawn before administration, not after.
