Question 1 of 5

A nurse is caring for a client who has a new prescription for heparin therapy. Which of the following laboratory tests should the nurse monitor?

Correct Answer: C

Rationale: The correct answer is C: Activated partial thromboplastin time (aPTT). When a client is on heparin therapy, aPTT is the most appropriate laboratory test to monitor because it assesses the effectiveness of heparin in preventing blood clot formation. A prolonged aPTT indicates that the heparin dose is within the therapeutic range. Platelet count (
A) assesses for heparin-induced thrombocytopenia, not the therapeutic effect of heparin. Prothrombin time (PT) (
B) and International normalized ratio (INR) (
D) are used to monitor warfarin therapy, not heparin.
