The nurse caring for a patient who is taking an anticoagulant should teach him to:
A) Report incidents of diarrhea.
B) Avoid foods high in vitamin K.
C) Use a straight razor when shaving.
D) Take aspirin for pain relief.
Ans: B
Feedback: The patient should avoid consuming large amounts of vitamin K because vitamin K can interfere with anticoagulation. The patient may need to report diarrhea, but this isn't an effect of taking an anticoagulant. An electric razor, not a straight razor, should be used to prevent cuts that cause bleeding. Aspirin may increase the risk of bleeding, so acetaminophen should be used for pain relief.
