Which statement regarding the treatment of a myocardial infarction is incorrect?

Thrombolytic agents can be used to dissolve a blood clot that is blocking coronary artery flow.

Patients are often kept on bedrest after initial diagnosis to reduce the workload of the heart.

Timely diagnosis of myocardial infarction is not a factor in the extent of muscle damage.

Percutaneous coronary intervention uses a stent to reopen the blocked coronary artery.

Answer and Explanation

The Correct Answer is C

Choice A Reason:Thrombolytic agents (clot-dissolving drugs) are indeed used to dissolve blood clots that block coronary artery flow during a heart attack. These medications help restore blood flow and prevent further damage to the heart muscle.

Choice B Reason:Bedrest is commonly recommended after a myocardial infarction (heart attack) to reduce the workload on the heart. It allows the heart to heal and minimizes strain during the recovery phase.

Choice C Reason:Timely diagnosis of myocardial infarction is crucial because early intervention can significantly impact the extent of muscle damage. Rapid treatment helps preserve heart tissue and prevent complications.

Choice D Reason:Percutaneous coronary intervention (PCI) involves using a stent to reopen a blocked coronary artery. This procedure restores blood flow and improves outcomes for patients with myocardial infarction.

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.

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.
