A patient who is taking clopidogrel (Plavix) calls the nurse to report black, tarry stools and coffee-ground emesis. The nurse will tell the patient to:
a. ask the provider about using aspirin instead of clopidogrel.
b. consume a diet high in vitamin K.
c. continue taking the clopidogrel until talking to the provider.
d. stop taking the clopidogrel immediately.
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.
