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 C

Explanation

Choice A rationale:

Aneurysms Aneurysms are not typically associated with chronic orthostatic hypotension. Aneurysms involve the weakening and ballooning of blood vessels, which can lead to life-threatening complications like rupture or dissection. However, they are not directly related to orthostatic hypotension.

Choice B rationale:

Heart failure Heart failure is a condition in which the heart cannot pump blood effectively, leading to symptoms like fluid retention, shortness of breath, and fatigue. While heart failure can cause orthostatic hypotension, it is not a complication that an older adult patient with chronic orthostatic hypotension should be primarily monitored for. Instead, the focus should be on addressing orthostatic intolerance and the risk of falls.

Choice C rationale:

Falls Chronic orthostatic hypotension is characterized by a drop in blood pressure upon standing, which can lead to dizziness, fainting, and falls. Monitoring for falls is crucial in older adults with this condition to prevent injuries and complications associated with falling. This is the correct choice because it directly addresses the potential risks associated with orthostatic hypotension.

Choice D rationale:

Atherosclerosis Atherosclerosis is a condition characterized by the buildup of fatty deposits in the arteries, which can lead to reduced blood flow to various organs. While atherosclerosis can contribute to cardiovascular issues, it is not the primary concern for an older adult with chronic orthostatic hypotension. The immediate concern is the risk of falls and related injuries.

A. Albumin and aldosterone. B. Sodium and potassium. C. Creatine phosphate (CK-MB) and troponin 1. D. Cholesterol and HDL.

Correct Answer is C

Explanation

Choice A rationale:

Albumin and aldosterone. Rationale: Albumin and aldosterone are not typically used to diagnose myocardial infarction. These are not specific markers for cardiac injury. Choice A is incorrect.

Choice B rationale:

Sodium and potassium. Rationale: Sodium and potassium levels are important for assessing electrolyte balance, but they are not specific indicators of myocardial infarction. Choice B is incorrect.

Choice C rationale:

Creatine phosphate (CK-MB) and troponin 1. Rationale: Creatine kinase-MB (CK-MB) and troponin 1 are specific cardiac markers that are elevated in the blood following a myocardial infarction. CK-MB is an isoenzyme of creatine kinase found primarily in the heart, and troponin is a protein released from damaged heart muscle cells. Elevated levels of these markers are indicative of myocardial infarction. Choice C is the correct answer.

Choice D rationale:

Cholesterol and HDL. Rationale: Cholesterol and HDL (High-Density Lipoprotein) levels are relevant for assessing cardiovascular risk but are not specific markers for myocardial infarction. Choice D is incorrect.
