Cardiovascular System Practice Exam

1. The client is receiving digoxin and complains of nausea. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to check the client’s digoxin level (Choice A). Nausea can be a sign of digoxin toxicity, so assessing the digoxin level is crucial to determine if the medication dosage needs adjustment. Continuing the current dose of digoxin (Choice B) may worsen the symptoms if toxicity is present. Administering an antiemetic (Choice C) may provide temporary relief but does not address the underlying issue of digoxin toxicity. Discontinuing digoxin immediately (Choice D) without assessing the digoxin level can be harmful if the medication is within the therapeutic range.

2. 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?

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.

3. What is the ability of cardiac cells to generate an electrical impulse without being stimulated by an external source?

Correct answer: A

Rationale: Automaticity is the correct answer because it refers to the inherent ability of cardiac cells to generate electrical impulses without the need for external stimulation. Contractility (Choice B) is the ability of the heart muscle to contract and generate force, not related to electrical impulse generation. Conductivity (Choice C) refers to the ability of cardiac cells to transmit electrical impulses from cell to cell, not the spontaneous generation of impulses. Refractoriness (Choice D) is the period during which the cardiac cells are recovering and not able to respond to a new stimulus, not the spontaneous generation of impulses.

4. What condition is characterized by the inflammation of the heart's outer lining, often causing chest pain and other symptoms?

Correct answer: A

Rationale: Pericarditis is the correct answer because it is the inflammation of the pericardium, the outer lining of the heart. This condition commonly presents with symptoms like chest pain. Endocarditis (choice B) is the inflammation of the inner lining of the heart chambers and valves. Myocarditis (choice C) is the inflammation of the heart muscle itself. Valvular heart disease (choice D) refers to various conditions affecting the heart valves, not specifically the outer lining of the heart.

5. What is the condition where the walls of the heart's ventricles become thickened, reducing the heart's ability to pump blood effectively?

Correct answer: A

Rationale: Ventricular hypertrophy is the correct answer. In ventricular hypertrophy, the walls of the heart's ventricles become thickened, which decreases the heart's efficiency in pumping blood. Atrial fibrillation (choice B) is an irregular and often rapid heart rate that can lead to poor blood flow. While restrictive cardiomyopathy (choice C) involves the heart muscle becoming rigid and less compliant, it is not specifically characterized by thickening of the ventricular walls. Cardiomyopathy (choice D) is a general term for diseases of the heart muscle, which can present with various symptoms and causes.
