Answer to Question 1

ANS: C
Patients who experience bleeding should be warned not to stop taking the clopidogrel until the prescriber says they should, since abrupt withdrawal may precipitate a thrombotic event. Taking aspirin with an active GI bleed is contraindicated. Warfarin is a vitamin K inhibitor; consuming extra vitamin K will not reverse the effects of clopidogrel.

Answer to Question 2

ANS: D
This patient does not exhibit any signs of bleeding from a warfarin overdose. The vital signs are stable, there are no hematomas or petechiae, and the patient does not have pain. A PT and INR should be drawn to evaluate the anticoagulant effects. Vitamin K may be given if laboratory values indicate overdose. Protamine sulfate is given for heparin overdose. PTT evaluation is used to monitor heparin therapy.
