A poststroke client is going home on oral warfarin (Coumadin). During discharge teaching, which statement by the client would reflect an understanding of the effects of this medication?
1. "I don't like green vegetables, so not eating them will be a pleasure.".
2. "I will stop taking this medicine if I notice any bruising.".
3. "It will be OK for me to eat anything, as long as it is low-fat.".
4. "I'll check my blood pressure frequently while taking this medication.".
"I don't like green vegetables, so not eating them will be a pleasure.".
Rationale: Warfarin is a vitamin K antagonist. Green, leafy vegetables contain vitamin K, and will therefore interfere with the therapeutic effects of the drug. Bruising is a common side effect, and the drug should not be stopped unless by prescriber order. Low-fat foods do not interfere with warfarin therapy. Warfarin is not prescribed to affect the blood pressure.
