1. The client on spironolactone should avoid which of the following?

• A. Foods high in potassium
• B. Foods high in sodium
• C. Foods high in calcium
• D. Foods high in chloride

Correct answer: A

Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and excrete sodium. Consuming foods high in potassium while on spironolactone can lead to an excess of potassium in the body, potentially causing hyperkalemia. Choices B, C, and D are incorrect because spironolactone does not directly interact with sodium, calcium, or chloride in a way that would require specific dietary restrictions related to these minerals.

2. What procedure is used to visualize the airways and diagnose lung disease?

• A. Bronchoscopy
• B. Thoracentesis
• C. Pulmonary function test
• D. Chest X-ray

Correct answer: A

Rationale: Bronchoscopy is the correct answer because it is a procedure specifically designed to visualize the airways and diagnose lung diseases by allowing doctors to examine the inside of the airways. Thoracentesis involves the removal of fluid from the pleural space around the lungs, not the airways. Pulmonary function tests assess how well the lungs work but do not visualize the airways directly. A chest X-ray provides an image of the lungs and surrounding structures but does not involve direct visualization of the airways.

3. Which type of lung cancer begins in the cells lining the bronchi and bronchioles?

• A. Adenocarcinoma
• B. Small cell lung cancer
• C. Squamous cell carcinoma
• D. Mesothelioma

Correct answer: A

Rationale: Adenocarcinoma is the correct answer because it is a type of lung cancer that originates in the cells lining the bronchi and bronchioles. Adenocarcinoma is one of the most common types of lung cancer, often found in non-smokers and more frequently in women. Small cell lung cancer (Choice B) typically starts in the bronchi, but it is characterized by its rapid growth and tendency to spread quickly. Squamous cell carcinoma (Choice C) usually begins in the squamous cells lining the bronchi and is strongly associated with smoking. Mesothelioma (Choice D) is a cancer that affects the lining of certain organs like the lungs, often caused by asbestos exposure, but it does not specifically start in the cells lining the bronchi and bronchioles.

4. Which of the following is a chronic condition where the heart muscle is weakened and unable to pump blood effectively, often leading to heart failure?

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

Correct answer: A

Rationale: Dilated cardiomyopathy is characterized by the heart muscle being weakened and unable to pump blood effectively, ultimately resulting in heart failure. Choice B, Hypertrophic cardiomyopathy, involves the heart muscle becoming abnormally thick, reducing the heart's efficiency. Choice C, Restrictive cardiomyopathy, refers to the heart becoming rigid and less able to fill with blood properly. Myocarditis, as in Choice D, is inflammation of the heart muscle usually caused by a viral infection and is different from the chronic weakening seen in dilated cardiomyopathy.

5. Which of the following is a type of heart valve disease where the aortic valve becomes narrowed, restricting blood flow from the heart to the rest of the body?

• A. Aortic stenosis
• B. Mitral stenosis
• C. Tricuspid regurgitation
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is Aortic stenosis. In aortic stenosis, the aortic valve becomes narrowed, which obstructs the blood flow from the heart to the rest of the body. This condition can lead to symptoms like chest pain, shortness of breath, and fainting. Mitral stenosis (choice B) involves narrowing of the mitral valve, not the aortic valve. Tricuspid regurgitation (choice C) is a condition where the tricuspid valve leaks, causing blood to flow backward in the heart. Pulmonary hypertension (choice D) is high blood pressure in the arteries of the lungs.
