Question 1 of 5

The nurse is preparing to administer warfarin (Coumadin), an oral anticoagulant, to a client diagnosed with a pulmonary embolus. Which data would cause the nurse to question administering the medication?

Correct Answer: B

Rationale: An INR of 5 (
B) is above the therapeutic range (2–3 for pulmonary embolus), indicating excessive anticoagulation and bleeding risk, so warfarin should be questioned. PTT (
A) is for heparin, not warfarin. PT (
C) alone is not standardized. ESR (
