Cardiovascular System Exam Questions Pdf

1. The nurse is caring for a client on digoxin. What is the most important assessment before administering this medication?

Correct answer: A

Rationale: The correct answer is to check the client’s heart rate before administering digoxin because one of the side effects of digoxin is bradycardia. Monitoring the heart rate is crucial to assess whether the client's heart rate is within the acceptable range before giving the medication. Checking the blood pressure (Choice B), respiratory rate (Choice C), or oxygen saturation (Choice D) are important assessments in general patient care, but they are not specifically related to the administration of digoxin.

2. Which of the following is a type of heart attack that occurs when the blood supply to part of the heart muscle is severely reduced or stopped?

Correct answer: A

Rationale: The correct answer is A: Myocardial infarction. Myocardial infarction, commonly known as a heart attack, occurs when the blood supply to part of the heart muscle is severely reduced or stopped, leading to tissue damage or death. Angina (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood. Stroke (choice C) is a condition where the blood supply to the brain is interrupted or reduced. Congestive heart failure (choice D) is a chronic condition where the heart muscle doesn't pump blood as well as it should.

3. Which artery supplies the right atrium, right ventricle, a portion of the septum, SA node, AV node, and inferior portion of the left ventricle?

Correct answer: A

Rationale: The correct answer is the right coronary artery. It supplies essential areas of the heart, including the right atrium, right ventricle, a portion of the septum, SA node, AV node, and the inferior portion of the left ventricle. The left circumflex artery primarily supplies the left atrium and lateral wall of the left ventricle, not the mentioned areas. The posterior descending artery supplies the inferior wall of the left ventricle, not the right side. The aortic artery is a general term and does not specifically refer to an artery that supplies the mentioned areas.

4. What is a condition where the walls of the arteries in the lungs become thickened and stiff, leading to increased blood pressure in the pulmonary arteries?

Correct answer: A

Rationale: Pulmonary hypertension is a condition characterized by the thickening and stiffening of the arteries in the lungs, resulting in elevated blood pressure in the pulmonary arteries. This condition is distinct from the other choices provided. Pulmonary fibrosis involves scarring of lung tissue, pulmonary embolism is a blockage in the pulmonary artery, and pulmonary edema is the accumulation of fluid in the lungs.

5. Which type of medication helps to reduce the workload on the heart by slowing down the heart rate?

Correct answer: A

Rationale: Beta-blockers are medications that work by blocking the action of hormones like adrenaline, thereby reducing the heart rate and the workload on the heart. This makes them effective in managing high blood pressure and various heart conditions. Calcium channel blockers work by relaxing blood vessels and reducing the heart's workload, but they do not primarily slow down the heart rate. Diuretics help the body get rid of excess salt and water by increasing urine production, which can lower blood pressure but not by slowing down the heart rate. ACE inhibitors work by relaxing blood vessels, not by directly affecting heart rate.
