1. What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?

• A. Coronary artery disease
• B. Atherosclerosis
• C. Pulmonary embolism
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD occurs when the coronary arteries are narrowed or blocked, reducing blood flow to the heart muscle and increasing the risk of chest pain or heart attack. Choice B, Atherosclerosis, is a condition characterized by the hardening and narrowing of arteries due to the buildup of plaque. Choices C and D, Pulmonary embolism and Pulmonary hypertension, involve issues related to the lungs and not the coronary arteries.

2. What type of therapy delivers high concentrations of oxygen to the lungs?

• A. Oxygen therapy
• B. Ventilator therapy
• C. Mechanical ventilation
• D. CPAP therapy

Correct answer: A

Rationale: Oxygen therapy is the correct answer because it specifically refers to a treatment that delivers high concentrations of oxygen to the lungs. This therapy is used for patients who require additional oxygen due to conditions affecting their breathing. Ventilator therapy (B), mechanical ventilation (C), and CPAP therapy (D) involve different mechanisms and purposes than delivering high concentrations of oxygen to the lungs.

3. Which surgical procedure involves removing a portion of the lung?

• A. Lobectomy
• B. Pneumonectomy
• C. Tracheostomy
• D. Bronchoscopy

Correct answer: A

Rationale: A lobectomy is the surgical removal of a lobe of the lung. This procedure is commonly performed to treat conditions like lung cancer or severe lung diseases. Pneumonectomy involves removing an entire lung, making it incorrect. Tracheostomy is a surgical procedure to create an opening in the windpipe, not involving lung tissue removal. Bronchoscopy is a diagnostic procedure that allows visualization of the airways using a thin, flexible tube with a camera, not involving lung tissue removal.

4. What is the accumulation of fatty deposits along the walls of arteries, leading to reduced blood flow?

• A. Atherosclerosis
• B. Arteriosclerosis
• C. Aneurysm
• D. Thrombosis

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It refers to the buildup of fatty deposits (plaque) along the inner walls of arteries, narrowing the blood vessels and reducing blood flow. This condition can lead to serious complications such as heart attacks or strokes. Arteriosclerosis (choice B) is a broader term that refers to the thickening and hardening of the arterial walls. While related, it is not as specific as atherosclerosis in describing the fatty deposit accumulation. Aneurysm (choice C) is the abnormal bulging of an artery wall that can rupture and cause internal bleeding, not specifically related to fatty deposits. Thrombosis (choice D) is the formation of a blood clot within a blood vessel, which can obstruct blood flow, but it is not directly related to the accumulation of fatty deposits.

5. Which procedure is used to remove excess fluid or air from the pleural space, helping to relieve pressure on the lungs?

• A. Thoracentesis
• B. Bronchoscopy
• C. Chest X-ray
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: The correct answer is Thoracentesis. Thoracentesis is a procedure specifically designed to remove excess fluid or air from the pleural space in the chest. This process helps to relieve pressure on the lungs and improve breathing. Bronchoscopy (Choice B) is a procedure used to visualize the airways and diagnose lung conditions, not to remove fluid from the pleural space. Chest X-ray (Choice C) is an imaging test that provides a picture of the structures inside the chest, including the lungs, heart, and bones. Arterial blood gas (ABG) test (Choice D) is a blood test that measures the levels of oxygen and carbon dioxide in the blood, providing information about how well the lungs are working, but it does not involve removing excess fluid or air from the pleural space.
