Which of the following patients is at the highest risk for silent myocardial ischemia caused by dysfunction of the autonomic nerves?

A patient with Alzheimer's disease.

Diabetes mellitus.

Hypertension.

Emphysema.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

A patient with Alzheimer's disease is at risk for various health complications, but the question specifically asks about the risk of silent myocardial ischemia caused by dysfunction of the autonomic nerves. While Alzheimer's disease may lead to autonomic nervous system dysfunction, diabetes mellitus is a more well-established risk factor for autonomic neuropathy, which can result in silent myocardial ischemia.

Choice B rationale:

Diabetes mellitus is a known risk factor for autonomic neuropathy, which can result in silent myocardial ischemia. Autonomic neuropathy affects the nerves that control vital functions such as heart rate, blood pressure, and digestion. This can lead to silent myocardial ischemia, where the patient may not feel the typical chest pain (angina) associated with reduced blood flow to the heart. Therefore, patients with diabetes are at the highest risk for this complication.

Choice C rationale:

Hypertension, while a risk factor for heart disease, is not directly linked to autonomic neuropathy and silent myocardial ischemia. Hypertension can lead to other cardiovascular complications but is not the primary risk factor for this specific complication mentioned in the question.

Choice D rationale:

Emphysema is primarily a lung condition and is not directly related to autonomic neuropathy or the risk of silent myocardial ischemia. While patients with emphysema may have increased cardiovascular risk due to chronic hypoxia, diabetes mellitus is a more significant risk factor for autonomic neuropathy and its associated complications, such as silent myocardial ischemia.

Correct Answer is B

Explanation

Choice A rationale:

"Chorea" is not related to the pathophysiology of acute rheumatic fever. Chorea is a movement disorder, but it is not a term associated with the immune response to group A streptococcal cell membrane antigens.

Choice B rationale:

"M proteins" are the key component involved in the pathophysiology of acute rheumatic fever. Group A streptococcal M proteins trigger an abnormal immune response that can lead to acute rheumatic fever and its associated complications, including rheumatic heart disease.

Choice C rationale:

"C-reactive protein" is not the primary antigen or component involved in the pathophysiology of acute rheumatic fever. While C-reactive protein may increase in response to inflammation, it is not the main factor responsible for the development of this condition.

Choice D rationale:

"Streptolysin O" is not the primary antigen involved in the pathophysiology of acute rheumatic fever. Streptolysin O is a toxin produced by group A streptococci, but it is not the antigen responsible for the abnormal immune response leading to acute rheumatic fever. .

A. Blood clots in the coronary artery. B. Hypoxemia from respiratory disease. C. Vasospasm. D. Deep vein thromboses potension.

Correct Answer is C

Explanation

Choice A rationale:

Prinzmetal angina is not caused by blood clots in the coronary artery. It is primarily due to vasospasm of the coronary arteries.

Choice B rationale:

Prinzmetal angina is not caused by hypoxemia from respiratory disease. It is a vascular issue, not a respiratory one.

Choice C rationale:

Prinzmetal angina is caused by vasospasm of the coronary arteries. This constriction reduces blood flow to the heart muscle, leading to chest pain.

Choice D rationale:

Prinzmetal angina is not caused by deep vein thrombosis or hypotension. It is primarily related to vasospasm in the coronary arteries.
