Question

A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following lab tests should the nurse review prior to adjusting the client's heparin?

A. Prothrombin time (PT)
B. Activated partial thromboplastin time (aPTT)
C. International normalized ratio (INR)
D. Platelet count

Answer 1

The nurse should review the Activated Partial Thromboplastin Time (aPTT) lab test.

Step-by-step explanation:

Prior to adjusting a client's heparin infusion, the nurse should review the Activated Partial Thromboplastin Time (aPTT) lab test. The aPTT measures the time it takes for blood to clot and is used to monitor the effectiveness of heparin therapy. By reviewing the aPTT, the nurse can determine if the client's heparin dosage needs to be adjusted to maintain therapeutic levels.
