Why should clients who take warfarin (Coumadin) refrain from food items such as green leafy vegetables and soybeans?

  • A. Because the foods contain Vitamin K, which reduces the anti coagulant effect of the medication
  • B. Because the foods contain Vitamin K, which increases the anti coagulant effect of the medication
  • C. Because the foods help stimulate salivation
  • D. Because the foods minimize the volume of food consumption
Correct Answer: A

Rationale: The correct answer is A because green leafy vegetables and soybeans are high in Vitamin K, which counteracts the anticoagulant effect of warfarin. Warfarin works by inhibiting Vitamin K-dependent clotting factors in the liver. By consuming Vitamin K-rich foods, the medication's effectiveness is reduced, leading to an increased risk of blood clot formation. Choices B, C, and D are incorrect because they do not address the specific interaction between Vitamin K and warfarin in affecting coagulation. Choice B suggests the opposite effect of what actually occurs. Choices C and D are irrelevant to the pharmacological mechanism of warfarin.
