Cardiovascular System Exam Questions And Answers Questions
Question 1 of 5
What procedure uses a balloon to open narrowed or blocked blood vessels in the heart?
Correct Answer: A
Rationale: The correct answer is A: Angioplasty. This procedure uses a balloon to open narrowed or blocked blood vessels in the heart. First, a catheter with a deflated balloon is inserted into the blocked artery. Then, the balloon is inflated to widen the artery and improve blood flow. This is a minimally invasive procedure commonly used to treat coronary artery disease. Choice B: Coronary artery bypass graft involves using blood vessels from another part of the body to bypass blocked arteries, not using a balloon. Choice C: Stent placement involves inserting a mesh tube to keep the artery open, but it does not use a balloon to open the vessel. Choice D: Valve replacement is a procedure to replace damaged heart valves and does not involve using a balloon to open narrowed arteries.
Question 2 of 5
What procedure uses a catheter to open up a blocked or narrowed coronary artery, often involving the placement of a stent?
Correct Answer: A
Rationale: The correct answer is A: Angioplasty. During angioplasty, a catheter with a balloon at its tip is inserted into the blocked or narrowed coronary artery to widen the artery and improve blood flow. This procedure often involves the placement of a stent to help keep the artery open. Angioplasty is a minimally invasive procedure compared to a coronary artery bypass graft (CABG), which requires open-heart surgery. Echocardiogram and CT angiography are diagnostic imaging tests and do not involve the insertion of a catheter to treat a blocked or narrowed coronary artery.
Question 3 of 5
What is the procedure where a small mesh tube is inserted into an artery to keep it open after angioplasty?
Correct Answer: A
Rationale: The correct answer is A: Stent placement. After angioplasty, a stent is inserted into the artery to prevent it from collapsing and keep it open. This procedure helps maintain blood flow and reduces the risk of blockages. Bypass surgery involves redirecting blood flow using a graft, not inserting a tube. Angioplasty is the initial procedure to open the blocked artery, not to keep it open. Valve replacement is a procedure for replacing damaged heart valves, not for arteries.
Question 4 of 5
What is the procedure where a device is used to shock the heart back into a normal rhythm during a life-threatening arrhythmia?
Correct Answer: A
Rationale: Defibrillation is the correct answer as it is the procedure where an electrical device delivers a shock to the heart to restore normal rhythm during a life-threatening arrhythmia. This shock helps reset the heart's electrical activity. Cardioversion (B) is similar but used for less severe arrhythmias. Echocardiogram (C) is an imaging test to assess heart function, not a treatment. Ablation (D) is a procedure to destroy abnormal heart tissue causing arrhythmias but not used for immediate life-threatening situations like defibrillation.
Question 5 of 5
Which test measures how well the lungs work by assessing the amount of air the lungs can hold and how quickly air can be exhaled?
Correct Answer: A
Rationale: The correct answer is A: Spirometry. Spirometry measures lung function by evaluating lung capacity and airflow. It assesses vital parameters like Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1), providing valuable insights into lung health. Pulse oximetry (B) measures oxygen saturation, not lung function. Arterial blood gas (C) evaluates blood oxygen and carbon dioxide levels, not lung capacity. Chest X-ray (D) shows lung structure, not lung function. Therefore, Spirometry is the most appropriate test for assessing lung function.
