Nursing Elites

1. What is a condition where the airways become swollen and produce extra mucus, making it difficult to breathe, often associated with COPD?

• A. Chronic bronchitis
• B. Pneumonia
• C. Emphysema
• D. Tuberculosis

Correct answer: A

Rationale: Chronic bronchitis is the correct answer. It is a long-term inflammation of the bronchi, leading to persistent cough and mucus production, commonly associated with chronic obstructive pulmonary disease (COPD). Pneumonia (Choice B) is an infection that inflames the air sacs in one or both lungs. Emphysema (Choice C) is a lung condition where the air sacs in the lungs are damaged, making it difficult to breathe. Tuberculosis (Choice D) is a bacterial infection that primarily affects the lungs.

2. The client on nitroglycerin complains of a headache. How does the nurse explain this?

• A. This is a normal side effect of nitroglycerin.
• B. This is an allergic reaction to nitroglycerin.
• C. This is an indication of overdose.
• D. This is a sign of heart failure.

Correct answer: A

Rationale: The correct answer is A: 'This is a normal side effect of nitroglycerin.' Headaches are a common side effect of nitroglycerin due to vasodilation. Choice B is incorrect because allergic reactions to nitroglycerin typically present with symptoms like rash, itching, or shortness of breath. Choice C is incorrect as an overdose of nitroglycerin would likely present with symptoms beyond just a headache. Choice D is incorrect because headaches related to nitroglycerin are not indicative of heart failure.

3. What is a condition where the right side of the heart fails due to increased pressure in the pulmonary arteries, often caused by chronic lung disease?

• A. Cor pulmonale
• B. Heart failure
• C. Pulmonary embolism
• D. Myocarditis

Correct answer: A

Rationale: Cor pulmonale is the correct answer. It is a condition where the right side of the heart fails due to increased pressure in the pulmonary arteries, often caused by chronic lung disease such as COPD. Pulmonary embolism (choice C) is a blockage in one of the pulmonary arteries in your lungs. Myocarditis (choice D) is inflammation of the heart muscle. While heart failure (choice B) is a broad term that can involve the failure of either the right or left side of the heart.

4. The nurse is administering a calcium channel blocker. What is the primary effect of this medication on the cardiovascular system?

• A. Decreases heart rate
• B. Increases heart rate
• C. Increases blood pressure
• D. Decreases blood pressure

Correct answer: D

Rationale: The correct answer is D: Decreases blood pressure. Calcium channel blockers primarily work by relaxing the blood vessels, leading to a decrease in blood pressure. Choice A, 'Decreases heart rate,' is incorrect because calcium channel blockers do not significantly affect heart rate. Choice B, 'Increases heart rate,' is incorrect as calcium channel blockers do not have a primary effect of increasing heart rate. Choice C, 'Increases blood pressure,' is incorrect as the primary effect of calcium channel blockers is to decrease blood pressure by vasodilation.

5. What is the primary effect of a calcium channel blocker on the heart?

• A. Decreases heart rate
• B. Increases heart rate
• C. Increases blood pressure
• D. Decreases blood pressure

Correct answer: D

Rationale: The correct answer is D: Decreases blood pressure. Calcium channel blockers primarily work by relaxing blood vessels, leading to a decrease in blood pressure. While these medications can have secondary effects on the heart, such as reducing the workload of the heart muscle, the primary effect related to blood pressure regulation. Therefore, choices A, B, and C are incorrect as they do not reflect the primary action of calcium channel blockers on the heart.
