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. For what reason might the nurse be given an order to administer milrinone (Primacor)?

• A. For congestive heart failure
• B. For hypertension
• C. For cardiac arrhythmias
• D. For bradycardia

Correct answer: A

Rationale: Milrinone is commonly prescribed for congestive heart failure to help improve cardiac function and alleviate symptoms. Choices B, C, and D are incorrect as milrinone is not typically used for hypertension, cardiac arrhythmias, or bradycardia. It is specifically indicated for congestive heart failure for short-term management.

3. The client is on a nitrate for angina. What is the most common side effect the nurse should monitor for?

• A. Headache
• B. Flushing
• C. Dizziness
• D. Nausea

Correct answer: A

Rationale: The correct answer is A, Headache. Nitrates commonly cause headaches as a side effect due to vasodilation. Flushing, dizziness, and nausea are less common side effects associated with nitrates. Flushing is more related to the dilation of blood vessels closer to the skin's surface, dizziness could occur but is not as common as headaches, and nausea is a less typical side effect of nitrates.

4. What is a condition where the lung's air sacs (alveoli) are damaged and enlarged, leading to breathlessness?

• A. Emphysema
• B. Chronic bronchitis
• C. Asthma
• D. Pulmonary fibrosis

Correct answer: A

Rationale: Emphysema is the correct answer. It is a condition where the air sacs in the lungs are damaged and enlarged, leading to breathlessness. Chronic bronchitis is characterized by inflammation of the bronchial tubes, not the alveoli. Asthma involves airway inflammation and constriction, not alveolar damage. Pulmonary fibrosis is a condition where lung tissue becomes thickened and scarred, different from the alveolar damage seen in emphysema.

5. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?

• A. Peripheral artery disease
• B. Raynaud's disease
• C. Varicose veins
• D. Pulmonary embolism

Correct answer: A

Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.
