Cardiovascular System Exam Questions

1. What is a condition where blood clots form in the deep veins, usually in the legs, and can travel to the lungs, causing serious complications?

Correct answer: A

Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when blood clots form in the deep veins, usually in the legs, and these clots can potentially travel to the lungs, leading to a pulmonary embolism. Pulmonary embolism (choice B) is a serious complication that can result from untreated DVT. Varicose veins (choice C) and peripheral artery disease (choice D) are not directly related to the formation of blood clots in deep veins that can lead to pulmonary embolism.

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

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.

3. What type of therapy delivers high concentrations of oxygen to the lungs?

Correct answer: A

Rationale: Oxygen therapy is the correct answer because it specifically refers to a treatment that delivers high concentrations of oxygen to the lungs. This therapy is used for patients who require additional oxygen due to conditions affecting their breathing. Ventilator therapy (B), mechanical ventilation (C), and CPAP therapy (D) involve different mechanisms and purposes than delivering high concentrations of oxygen to the lungs.

4. The client on amiodarone develops symptoms of hypothyroidism. What is the nurse’s best response?

Correct answer: C

Rationale: When a client on amiodarone develops symptoms of hypothyroidism, the nurse's best response is to monitor the client's thyroid function tests regularly. Amiodarone can affect thyroid function, so monitoring is essential to assess the impact and adjust treatment if necessary. Notifying the healthcare provider immediately (Choice A) may be necessary in some cases but the priority is to monitor first. Reassuring the client (Choice B) is not sufficient as monitoring is crucial. Discontinuing amiodarone (Choice D) abruptly without healthcare provider guidance can lead to serious consequences.

5. The client asks about side effects of taking digoxin. How does the nurse respond?

Correct answer: A

Rationale: The correct answer is A: 'Anorexia can be a side effect of digoxin.' Anorexia, nausea, vomiting, and diarrhea are commonly known side effects of digoxin. Choice B, 'Tachycardia can be a side effect of digoxin,' is incorrect as digoxin is used to treat tachycardia, not cause it. Choice C, 'Constipation can be a side effect of digoxin,' is incorrect as constipation is not a typical side effect of digoxin. Choice D, 'Urinary retention can be a side effect of digoxin,' is also incorrect as urinary retention is not a common side effect associated with digoxin use.
