Correct Answer is C

Explanation

A. Valerian is an herbal supplement commonly used for its sedative effects. It does not have a significant interaction with warfarin and is not contraindicated for concurrent use.
B. Probiotics are generally safe to use with warfarin and do not have a significant impact on its anticoagulant effects. They are not contraindicated for concurrent use.
C. Ginkgo biloba is known to increase the risk of bleeding when taken with warfarin. It has antiplatelet effects that can enhance the anticoagulant effects of warfarin, leading to an increased risk of bleeding complications. Therefore, it is contraindicated for concurrent use with warfarin.
D. Coenzyme Q10 is structurally similar to vitamin K and can potentially reduce the effectiveness of warfarin. However, it is not as strongly contraindicated as ginkgo biloba, which has a more pronounced effect on bleeding risk.

A. Give diphenhydramine IM. B. Elevate the client’s legs and feet. C. Administer epinephrine IM. D. Replace the infusion with 0.9% sodium chloride.

Correct Answer is C

Explanation

A. Give diphenhydramine IM. This action is incorrect because while diphenhydramine can help manage allergic reactions, it is not the first-line treatment for anaphylaxis. Epinephrine is the priority medication for anaphylactic reactions.
B. Elevate the client’s legs and feet. This action is incorrect because while elevating the legs can help with shock, it is not the immediate priority in anaphylaxis. Administering epinephrine is the most critical step.
C. Administer epinephrine IM. This action is correct because epinephrine is the first-line treatment for anaphylaxis. It helps to reverse the severe symptoms of anaphylaxis, including airway constriction and low blood pressure.
D. Replace the infusion with 0.9% sodium chloride. This action is incorrect because while replacing the infusion can help maintain fluid balance, it is not the immediate priority. Administering epinephrine is the most critical step.
