Question 1 of 5

A nurse is reviewing the laboratory results of a client who is receiving heparin by continuous IV infusion. Which of the following results indicates the nurse should decrease the infusion rate?

Correct Answer: B

Rationale: The correct answer is B: aPTT 90 seconds. The activated partial thromboplastin time (aPTT) measures the effectiveness of heparin therapy. A result of 90 seconds indicates the blood is taking longer to clot, suggesting the client may be at risk for bleeding.
Therefore, the nurse should decrease the heparin infusion rate to prevent excessive anticoagulation.

A: Erythrocyte sedimentation rate is a nonspecific marker of inflammation and does not directly relate to heparin therapy.
C: INR of 1.2 is within the therapeutic range for heparin, so no adjustment is needed.
D: Platelet count of 350,000/mm is within normal limits and does not necessitate a change in heparin infusion rate.
