A female client who is a vegetarian has a new prescription for warfarin. The client states she eats leafy green vegetables every day. How should the nurse respond?
Correct answer
C
Rationale
Leafy greens, high in vitamin K, reduce warfarinÔÇÖs anticoagulant effect (C) (matches 55-Q46). Informing the provider ensures dose adjustment. Substituting vegetables (A) is unnecessary. Praising (B) or claiming enhanced efficacy (D) ignores the interaction.
