Nursing Elites

1. What is a chronic condition where the heart muscle becomes weakened and enlarged, reducing its ability to pump blood effectively?

• A. Dilated cardiomyopathy
• B. Hypertrophic cardiomyopathy
• C. Myocarditis
• D. Pericarditis

Correct answer: A

Rationale: Dilated cardiomyopathy is characterized by the weakening and enlargement of the heart muscle, leading to its reduced ability to pump blood effectively. This condition is different from hypertrophic cardiomyopathy, which involves abnormal thickening of the heart muscle, myocarditis, which is inflammation of the heart muscle, and pericarditis, which is inflammation of the pericardium. Therefore, the correct answer is Dilated cardiomyopathy.

2. What type of medication is used to relax the muscles around the airways and improve breathing in conditions like asthma and COPD?

• A. Bronchodilator
• B. Corticosteroid
• C. Mucolytic
• D. Antihistamine

Correct answer: A

Rationale: Bronchodilators are medications that relax the muscles around the airways, improving airflow and making breathing easier for patients with asthma or COPD. Corticosteroids are anti-inflammatory drugs used to reduce airway inflammation, while mucolytics help in thinning and clearing mucus. Antihistamines are used to treat allergies and not specifically to improve breathing in conditions like asthma or COPD.

3. Which condition involves the tearing of the aorta, leading to severe pain and internal bleeding?

• A. Aortic dissection
• B. Aneurysm
• C. Stroke
• D. Myocardial infarction

Correct answer: A

Rationale: The correct answer is Aortic dissection. Aortic dissection is a life-threatening condition where the inner layer of the aorta tears, causing severe chest or back pain and internal bleeding, requiring immediate medical attention. Choice B, aneurysm, involves a bulging or weakening of a blood vessel wall, which is different from a tear in the aorta. Choices C and D, stroke and myocardial infarction, do not directly involve the tearing of the aorta and are distinct conditions.

4. A client on a beta blocker has a blood pressure of 90/60 mm Hg. What is the nurse’s priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Administer a diuretic to reduce blood pressure.
• D. Continue to monitor the client and reassess in 30 minutes.

Correct answer: A

Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A blood pressure of 90/60 mm Hg is already low, and beta blockers can further decrease blood pressure. Administering the beta blocker can potentially worsen the situation, leading to complications. Administering a diuretic or continuing to monitor the client without taking immediate action could delay necessary intervention. Therefore, holding the beta blocker and involving the healthcare provider promptly is crucial in this scenario.

5. What is the buildup of plaque in the arteries that can lead to heart attack, stroke, and other cardiovascular diseases?

• A. Atherosclerosis
• B. Arteriosclerosis
• C. Hypertension
• D. Diabetes

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It is the buildup of plaque in the arteries, leading to the narrowing of blood vessels, reduced blood flow, and an increased risk of heart attacks, strokes, and other cardiovascular diseases. Arteriosclerosis (choice B) refers to the hardening and thickening of arterial walls, while hypertension (choice C) is high blood pressure, and diabetes (choice D) is a metabolic disorder characterized by high blood sugar levels. Therefore, choices B, C, and D are incorrect in the context of the question.
