Cardiovascular System Exam Questions And Answers Questions
Question 1 of 5
What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?
Correct Answer: A
Rationale: The correct answer is A: Chronic bronchitis. Chronic bronchitis is characterized by inflammation and narrowing of the bronchial tubes, often caused by smoking. This condition leads to persistent coughing and mucus production. Emphysema (B) is a separate condition where the air sacs in the lungs are damaged, causing shortness of breath. Asthma (C) is a chronic respiratory condition characterized by airway inflammation and bronchospasms, triggered by various factors. Tuberculosis (D) is a bacterial infection that primarily affects the lungs, causing symptoms like coughing up blood and weight loss. Chronic bronchitis specifically relates to the inflammation and narrowing of the bronchial tubes due to smoking.
Question 2 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 3 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 4 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.
Question 5 of 5
What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?
Correct Answer: A
Rationale: The correct answer is A: Pneumonia. Pneumonia is characterized by inflammation and fluid or pus accumulation in the lung's air sacs. This leads to symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (B) is a bacterial infection affecting the lungs but does not always involve fluid accumulation. Asthma (C) is a chronic respiratory condition characterized by airway inflammation and bronchospasms, not fluid-filled air sacs. Bronchitis (D) is inflammation of the bronchial tubes, not the air sacs in the lungs.
