A nurse in a clinic is caring for a client who has recently begun taking warfarin. The nurse is reviewing potential drug and food interaction risks and should instruct the client to avoid which of the following?

Cabbage

Green beans

White beans

Cantaloupe

Answer and Explanation

The Correct Answer is A

A. Cabbage: This is the correct answer. Cabbage is a food high in vitamin K, which can antagonize the effects of warfarin. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-rich foods, such as cabbage, can affect the stability of the client's international normalized ratio (INR).

B. Green beans: Green beans are not particularly high in vitamin K, and their consumption is not usually restricted for clients taking warfarin.

C. White beans: White beans are not particularly high in vitamin K, and their consumption is not usually restricted for clients taking warfarin.

D. Cantaloupe: Cantaloupe is not high in vitamin K, and its consumption is not usually restricted for clients taking warfarin.

Correct Answer is C

Explanation

A. The pain persists with rest and organic nitrates: This statement is incorrect. Anginal pain typically improves with rest and can be relieved by the administration of organic nitrates.

B. The pain usually lasts longer than 20 min: This statement is incorrect. Anginal pain is often brief and lasts for a few minutes, typically less than 20 minutes.

C. Exertion and anxiety can trigger the pain: This is the correct answer. Anginal pain is often triggered by activities that increase the workload of the heart, such as exertion or emotional stress (anxiety). These triggers lead to an increased demand for oxygen by the heart muscle, which may exceed the compromised blood supply, resulting in angina.

D. The pain often radiates to the jaw or the back: This statement is correct. Anginal pain may radiate to the jaw, back, shoulder, arm, or neck. The radiation of pain is a characteristic feature of angina.

A. It requires lying quietly on one side." B. It might cause slight discomfort in the chest area." C. "It is best to have no food or beverages the day of the test." D. "It takes about 5 or 10 minutes."

Correct Answer is A

Explanation

A. "It requires lying quietly on one side": This is the correct answer. During an echocardiogram, the client is typically asked to lie on their left side to obtain clear images of the heart. The test is non-invasive and involves using ultrasound waves to create images of the heart's structures.

B. "It might cause slight discomfort in the chest area": Echocardiograms are generally painless and do not cause discomfort. They are a non-invasive imaging technique that uses sound waves.

C. "It is best to have no food or beverages the day of the test": While the client may be instructed to avoid eating or drinking shortly before the test, this statement is too restrictive. The specific fasting instructions will be provided by the healthcare provider or facility.

D. "It takes about 5 or 10 minutes": The duration of an echocardiogram can vary, but it typically takes longer than 5 or 10 minutes. The test duration depends on various factors, including the complexity of the study and the information needed.
