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.”
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: 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.
Correct Answer is C
Explanation
Choice A reason: Respiratory alkalosis is typically associated with hyperventilation, which is not common in acute pulmonary edema.
Choice B reason: Metabolic acidosis can occur in pulmonary edema due to tissue hypoxia and lactic acid production, but respiratory acidosis is more directly related to the primary problem of gas exchange.
Choice C reason: Respiratory acidosis is likely in acute pulmonary edema due to impaired gas exchange and CO2 retention.
Choice D reason: Metabolic alkalosis is not typically associated with acute pulmonary edema and is less likely than respiratory acidosis in this context.
