Cardiovascular System Exam Questions

1. What is a surgical procedure to create an opening in the windpipe to assist with breathing?

Correct answer: A

Rationale: Tracheostomy is the correct answer. It is a surgical procedure to create an opening in the windpipe (trachea) to assist with breathing. This procedure is commonly used for patients who require long-term ventilation support. Choice B, Lobectomy, involves the removal of a lobe of the lung and is not related to creating an opening in the windpipe. Choice C, Thoracotomy, is a surgical incision into the chest wall and is not specifically related to creating an opening in the windpipe. Choice D, Pleurodesis, is a procedure to treat recurrent pleural effusions by causing the pleural layers to stick together, and it is not related to creating an opening in the windpipe.

2. The client on nitroglycerin patches reports dizziness when standing up. What is the nurse’s best response?

Correct answer: A

Rationale: The correct answer is to advise the client to rise slowly to prevent dizziness. Dizziness when standing up can be a sign of orthostatic hypotension, a common side effect of nitroglycerin. Rising slowly can help minimize this symptom. Instructing the client to discontinue the nitroglycerin patches (Choice B) is not appropriate without consulting a healthcare provider as sudden discontinuation can lead to adverse effects. Encouraging the client to rest and avoid physical activity (Choice C) does not address the specific issue of orthostatic hypotension. Suggesting the client take an over-the-counter antiemetic (Choice D) is not indicated for dizziness related to orthostatic hypotension.

3. What term describes the phenomenon wherein decreased BP causes a reflex SNS response with increased pulse, increased contractility, and vasoconstriction; and increased BP causes reflex vagal responses resulting in decreased heart rate and passive vasodilation in the systemic arterioles?

Correct answer: A

Rationale: The correct answer is A: Baroreflex. The Baroreflex is a mechanism by which the body maintains blood pressure homeostasis through reflexive adjustments in heart rate and vascular tone. Choice B, Cheyne-Stokes breathing, is a pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing. Choices C and D, Frank-Starling Law and Starling reflex, are related to the intrinsic ability of the heart to adjust its output based on venous return, not specifically regulating blood pressure through reflex adjustments in heart rate and vascular tone as seen in the described phenomenon.

4. What is a condition where the heart's electrical impulses are delayed or blocked, leading to a slower or irregular heartbeat?

Correct answer: A

Rationale: Heart block is the correct answer because it specifically refers to a condition where the heart's electrical impulses are delayed or blocked, resulting in a slower or irregular heartbeat. Tachycardia (choice B) is a condition characterized by a fast heart rate, Bradycardia (choice C) is a slow heart rate, and Arrhythmia (choice D) is a general term used to describe any abnormal heart rhythm, which may or may not involve delays or blocks in electrical impulses.

5. The healthcare provider is monitoring a client on an ACE inhibitor. What lab value is most important to monitor?

Correct answer: A

Rationale: The correct answer is A: Potassium. When a client is on an ACE inhibitor, it is crucial to monitor potassium levels because ACE inhibitors can lead to an increase in potassium, potentially causing hyperkalemia. Monitoring sodium levels (Choice B) is not as critical in this scenario. Creatinine levels (Choice C) are important for assessing kidney function but are not the most crucial lab value to monitor with ACE inhibitors. Calcium levels (Choice D) are not directly affected by ACE inhibitors and are not the priority for monitoring in this case.
