The nurse would evaluate a female patient, age 68, as understanding teaching on the purpose of coronary artery bypass graft surgery if she made which of the following statements?

“It is done to increase blood flow to the myocardium.”

“It will decrease blood flow to the coronary arteries.”

“It cures coronary artery disease.”

“It prevents spasms of the coronary arteries.”

Answer and Explanation

The Correct Answer is A

Choice A Reason:Coronary artery bypass graft surgery (CABG) is not primarily performed to increase blood flow to the myocardium. Instead, it aims to restore blood flow to areas of the heart affected by blockages.

Choice B Reason:CABG does not intentionally decrease blood flow to the coronary arteries. On the contrary, it creates a new pathway to bypass blocked or partially blocked coronary arteries, improving blood flow to the heart muscle.

Choice C Reason:The primary purpose of CABG is to treat coronary artery disease by restoring blood flow to areas of the heart that aren't receiving enough blood. It involves using healthy blood vessels (usually from the chest or leg) to create a detour around blockages. By doing so, CABG improves heart function and reduces symptoms related to ischemia.

Choice D Reason:While CABG can indirectly prevent spasms of the coronary arteries by improving blood flow, it is not its primary purpose.

Correct Answer is C

Explanation

Choice A reason: Ensuring safety is important, but it does not directly address the immediate risk of suicide as effectively as understanding the client's intentions.

Choice B reason: Informing the provider is a critical step, but it should follow after assessing the immediate risk to the client's safety.

Choice C reason: Questioning the client about a suicide plan and method is the most immediate and direct way to assess the risk of suicide and take appropriate safety measures.

Choice D reason: Administering medication is important for managing anxiety but does not take precedence over assessing the risk of suicide in a client expressing such thoughts.

A. No gluten. B. No extra salt. C. No processed lunch meat. D. No caffeine.

Correct Answer is C

Explanation

Choice A reason: Gluten is not typically restricted for patients taking MAOIs unless they have a separate condition that requires this diet.

Choice B reason: Extra salt does not interact with MAOIs, so it is not necessary to avoid it unless the patient has other health concerns that require a low-sodium diet.

Choice C reason: Processed lunch meats are high in tyramine, which can cause dangerous interactions with MAOIs, leading to hypertensive crises.

Choice D reason: While caffeine may need to be limited, it is not as critical as avoiding high-tyramine foods like processed lunch meats when taking MAOIs.
