Warfarin sodium (Coumadin) is ordered for a client.
The client asks the nurse about dietary restrictions while taking this medication. Which of the following foods should be limited?
Wheat bread and butter.
Mangoes and tomatoes.
Spinach and salads.
Aged cheeses and wine.
The Correct Answer is C
This is because spinach and salads contain a lot of vitamin K, which can make warfarin less effective at preventing blood clots.
Vitamin K helps the blood to clot, so eating foods high in vitamin K can counteract the effect of warfarin.
Choice A is wrong because wheat bread and butter do not contain a lot of vitamin K and do not affect warfarin.
Choice B is wrong because mangoes and tomatoes do not contain a lot of vitamin K and do not affect warfarin.
Choice D is wrong because aged cheeses and wine do not contain a lot of vitamin K and do not affect warfarin.
It is important to keep a stable diet while taking warfarin and avoid sudden changes in the amount of vitamin K intake. Foods that are high in vitamin K include green leafy vegetables, chickpeas, liver, egg yolks, avocado, and olive oil.
These foods should be limited but not eliminated from the diet. Do not drink cranberry or grapefruit juice while taking warfarin as they can increase the risk of bleeding.

Correct Answer is C
Explanation
Orient the client to the arrangement of the room to promote independence. This strategy helps the client who is blind to navigate the environment safely and confidently. It also shows respect for the client’s autonomy and dignity.
Choice A is wrong because speaking loudly is not necessary for a client who is blind, unless they also have hearing impairment. Speaking loudly may imply that the client is less intelligent or capable, which is not true.
Choice B is wrong because touching the client prior to speaking may startle or frighten them. It is better to identify oneself verbally and ask for permission before touching the client.
Choice D is wrong because keeping the bed in the highest position may increase the risk of injury if the client tries to get out of bed alone. It also restricts the client’s mobility and independence, which may affect their self-esteem and quality of life.
Correct Answer is A
Explanation
This is the most therapeutic response because it shows respect for the client’s autonomy and allows the nurse to explore the client’s concerns and feelings about the medication.
It also helps to establish trust and rapport with the client. Choice B. Report refusal to the charge nurse.
This is wrong because it does not address the client’s immediate needs and may make the client feel ignored or dismissed.
Choice C. Explain the purpose of the medication.
This is wrong because it may sound like lecturing or persuading the client, which can increase resistance and hostility.
Choice D. Encourage the client to take the medication.
This is wrong because it does not acknowledge the client’s right to refuse treatment and may imply that the nurse knows better than the client what is best for them.
