A client is receiving heparin therapy. Which laboratory value should be monitored by the nurse to evaluate the effectiveness of the therapy?

  • A. PT
  • B. aPTT
  • C. INR
  • D. Platelet count
Correct Answer: B

Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications.
