Cardiovascular System Exam Questions And Answers

1. The client on warfarin has an INR of 1.2. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to increase the dose of warfarin. An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating that the dose is subtherapeutic. The priority action in this situation is to adjust the dose to achieve the target therapeutic INR range (usually 2-3) to prevent thromboembolic events. Administering vitamin K is not necessary as the INR is low, and there are no signs of bleeding. Monitoring for signs of bleeding is important but not the priority in this case since the INR is subtherapeutic. Holding the next dose and notifying the healthcare provider would delay the intervention needed to adjust the dose and achieve the therapeutic range.

2. Which condition is characterized by the narrowing or blockage of arteries that supply blood to the heart by plaque?

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD specifically refers to the condition where the arteries supplying blood to the heart become narrowed or blocked by plaque buildup. Choice B, Atherosclerosis, is a general term for the hardening and narrowing of arteries due to plaque buildup but does not specifically mention the heart. Choice C, Peripheral artery disease, involves narrowing of arteries that supply blood to areas other than the heart. Choice D, Congestive heart failure, is a condition where the heart is unable to pump blood effectively but is not primarily caused by narrowed or blocked arteries.

3. What is a condition where the airways become inflamed and narrow, making breathing difficult?

Correct answer: A

Rationale: Asthma is the correct answer. It is a condition characterized by inflammation, narrowing, and swelling of the airways, leading to symptoms like wheezing, shortness of breath, and coughing. Bronchitis is the inflammation of the bronchial tubes; Pleurisy is inflammation of the tissues that line the lungs and chest cavity; Tuberculosis is a bacterial infection that mainly affects the lungs.

4. This is a procedure where a small mesh tube is inserted into an artery to keep it open and improve blood flow.

Correct answer: A

Rationale: Stent placement is a procedure where a small mesh tube (stent) is inserted into an artery to keep it open and improve blood flow, often following angioplasty.

5. Which heart chamber ejects blood into the lungs via the pulmonary artery?

Correct answer: C

Rationale: The correct answer is C, the right ventricle. The right ventricle is responsible for pumping deoxygenated blood into the lungs through the pulmonary artery for oxygenation. Choices A, B, and D are incorrect because the right atrium receives deoxygenated blood from the body, the left atrium receives oxygenated blood from the lungs, and the left ventricle pumps oxygenated blood to the body, respectively.
