Question 1 of 5

A nurse is caring for a patient who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse monitor? Which lab test should the nurse monitor for heparin?

Correct Answer: B

Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). aPTT is the most appropriate lab test to monitor for patients receiving heparin therapy because it reflects the drug's anticoagulant effect. Heparin works by inhibiting thrombin and factor Xa, which can be measured effectively by monitoring aPTT levels. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to monitor for potential heparin-induced thrombocytopenia, but aPTT is more directly related to heparin's anticoagulant effect.
