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 B
Explanation
This is because the nurse’s reply does not address the client’s fear of radiation therapy, but rather provides factual information that may not be relevant or helpful to the client.
The nurse is not using a therapeutic communication technique, such as reflecting, exploring, or validating the client’s feelings.
Instead, the nurse is shutting down the communication and missing an opportunity to learn more about the client’s concerns and needs.
Choice A is wrong because the nurse is not confronting a painful subject, but rather avoiding it.
The nurse is not acknowledging the client’s fear or inviting the client to talk more about it.
Choice C is wrong because the nurse is not recognizing that the client needs information, but rather assuming that the client does.
The nurse is not asking the client what he or she wants to know about radiation therapy, but rather telling the client what he or she should know.
Choice D is wrong because the nurse is not perceiving that the client is ready to hear more about the treatment, but rather imposing information on the client.
The nurse is not assessing the client’s readiness to learn, but rather giving unsolicited advice.
Correct Answer is B
Explanation
This is because itching is a subjective assessment finding, which means it is based on the personal experience, view or feeling of the
patient. The other choices are objective assessment findings, which means they are based on observable or measurable data that the nurse can collect.
For example:
Choice A is wrong because hives are a visible skin reaction that can be seen and measured by the nurse.
Choice C is wrong because vomiting is an observable action that can be verified and recorded by the nurse.
Choice D is wrong because abdominal distension is a measurable change in the size or shape of the abdomen that can be assessed by the nurse.
Normal ranges for objective assessment findings may vary depending on the source and context, but some possible examples are:
- Hives: No hives or rashes on the skin are normal.
- Vomiting: No vomiting or nausea are normal.
- Abdominal distension: Normal abdominal girth for adults ranges from 68 to 100 cm (27 to 40 inches).
