Cardiovascular System Exam Questions
1. What is a surgical procedure to create an opening in the windpipe to assist with breathing?
- A. Tracheostomy
- B. Lobectomy
- C. Thoracotomy
- D. Pleurodesis
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. Which of the following is a rare but serious condition where the pulmonary arteries become narrowed, increasing the blood pressure in the lungs?
- A. Pulmonary hypertension
- B. Pulmonary embolism
- C. Pulmonary fibrosis
- D. Aortic stenosis
Correct answer: A
Rationale: The correct answer is A, Pulmonary hypertension. Pulmonary hypertension is a rare but serious condition characterized by high blood pressure in the arteries of the lungs, which can lead to heart failure. Pulmonary embolism (choice B) involves a blockage in one of the pulmonary arteries in the lungs. Pulmonary fibrosis (choice C) is a lung disease that causes lung tissue scarring. Aortic stenosis (choice D) is a condition where the aortic valve narrows, affecting blood flow from the heart.
3. The nurse is administering a calcium channel blocker. What is the primary effect of this medication on the cardiovascular system?
- A. Decreases heart rate
- B. Increases heart rate
- C. Increases blood pressure
- D. Decreases blood pressure
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.
4. What is a blood clot that forms in a vein, often in the legs, and can cause serious complications if it travels to the lungs?
- A. Deep vein thrombosis (DVT)
- B. Pulmonary embolism
- C. Varicose veins
- D. Atherosclerosis
Correct answer: A
Rationale: The correct answer is Deep vein thrombosis (DVT). DVT is a blood clot that forms in a deep vein, typically in the legs, and can lead to serious complications if it breaks loose and travels to the lungs, causing a pulmonary embolism. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs but are not related to blood clots. Atherosclerosis (choice D) is a condition where arteries become narrowed and hardened due to a buildup of plaque, not directly related to blood clots.
5. What is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle?
- A. Coronary artery disease (CAD)
- B. Atherosclerosis
- C. Stroke
- D. Peripheral artery disease
Correct answer: A
Rationale: The correct answer is A, Coronary artery disease (CAD). CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle and an increased risk of heart attack. Choice B, Atherosclerosis, is a related condition involving the buildup of fats, cholesterol, and other substances in and on the artery walls, but it is not specific to the coronary arteries. Choices C and D, Stroke and Peripheral artery disease, respectively, involve different arteries and conditions, not directly related to the narrowing or blockage of the coronary arteries.
