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. The nurse is giving the client digoxin for heart failure and recognizes that the drug has what type of effect on the heart?

• A. Negative inotropic, negative chronotropic effect
• B. Positive inotropic, negative chronotropic effect
• C. Negative inotropic, positive chronotropic effect
• D. Positive inotropic, positive chronotropic effect

Correct answer: B

Rationale: The correct answer is B: Positive inotropic, negative chronotropic effect. Digoxin strengthens the heart muscle, providing a positive inotropic effect, which increases the force of contraction. It also decreases the heart rate, having a negative chronotropic effect. Choice A is incorrect because digoxin has a positive inotropic effect, not a negative inotropic effect. Choice C is incorrect as digoxin does not have a positive chronotropic effect but a negative one. Choice D is incorrect because while digoxin has a positive inotropic effect, it does not have a positive chronotropic effect.

3. Which of the following is a genetic disorder that causes thick, sticky mucus to build up in the lungs and digestive system, leading to severe respiratory and digestive problems?

• A. Cystic fibrosis
• B. Pulmonary fibrosis
• C. Pulmonary edema
• D. Bronchiectasis

Correct answer: A

Rationale: The correct answer is A, cystic fibrosis. Cystic fibrosis is a genetic disorder characterized by the buildup of thick, sticky mucus in the lungs and digestive system, resulting in severe respiratory and digestive issues. Choice B, pulmonary fibrosis, involves scarring and thickening of lung tissue, not excessive mucus production. Choice C, pulmonary edema, refers to fluid accumulation in the lungs, not mucus buildup. Choice D, bronchiectasis, is a condition where the airways in the lungs are damaged and widened, leading to chronic cough and sputum production, but it does not specifically involve the thick, sticky mucus characteristic of cystic fibrosis.

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. What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?

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

Correct answer: A

Rationale: Chronic bronchitis is the correct answer because it is a long-term condition characterized by inflammation and narrowing of the bronchial tubes in the lungs, commonly triggered by smoking. Emphysema involves damage to the air sacs in the lungs, not specifically the bronchial tubes. Asthma is a condition of reversible airway obstruction usually due to allergies or other triggers, not solely smoking. Tuberculosis is a bacterial infection that primarily affects the lungs but is not directly related to inflammation and narrowing of the bronchial tubes.
