Question 1 of 5

The nurse is monitoring the aPTT level for an assigned client. Which of the following medications requires this type of laboratory monitoring?

Correct Answer: D

Rationale: The correct answer is D: Heparin. Heparin is an anticoagulant medication that works by inhibiting thrombin and factor Xa. Monitoring aPTT levels is crucial to assess the effectiveness and safety of heparin therapy. The aPTT measures the intrinsic pathway of coagulation, which heparin affects. Clopidogrel (
A) and Warfarin (
B) are not monitored by aPTT; they are monitored by platelet function tests and INR respectively. Enoxaparin (
C) is monitored by anti-Xa levels, not aPTT.
Therefore, the correct choice is heparin due to its mechanism of action and the need for aPTT monitoring.
