1. What is a procedure to remove fluid or air from the pleural space to help a patient breathe easier?

• A. Thoracentesis
• B. Bronchoscopy
• C. Chest X-ray
• D. CT scan

Correct answer: A

Rationale: Correct! Thoracentesis is the correct answer. It is a procedure where fluid or air is removed from the pleural space in the chest to help the patient breathe more easily. Bronchoscopy (choice B) is a procedure to visualize the airways, while Chest X-ray (choice C) and CT scan (choice D) are imaging tests and do not involve the removal of fluid or air from the pleural space.

2. What is this surgical procedure that restores blood flow to the heart by diverting blood around a blocked artery?

• A. Coronary artery bypass graft (CABG)
• B. Angioplasty
• C. Stent placement
• D. Valve replacement

Correct answer: A

Rationale: The correct answer is A, Coronary artery bypass graft (CABG), which is a surgical procedure to improve blood flow to the heart by redirecting blood around blocked or narrowed arteries. This procedure is specifically designed to bypass blocked coronary arteries, allowing blood to flow more freely to the heart muscle. Choices B, C, and D are incorrect because angioplasty involves opening up narrowed or blocked blood vessels, stent placement involves inserting a mesh tube to keep arteries open, and valve replacement involves replacing a damaged heart valve - none of which directly address diverting blood flow around a blocked artery.

3. 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.

4. Which valves close during ventricular systole and open during ventricular diastole?

• A. Semilunar valves
• B. Atrioventricular Valves
• C. Mitral valve
• D. Tricuspid valve

Correct answer: B

Rationale: The correct answer is B: Atrioventricular Valves. The atrioventricular (AV) valves, including the mitral valve and tricuspid valve, close during ventricular systole to prevent backflow of blood from the ventricles into the atria. They open during ventricular diastole to allow blood flow from the atria into the ventricles. Semilunar valves, choice A, are located at the exits of the ventricles and prevent backflow into the ventricles. The mitral valve and tricuspid valve, choices C and D, are specific types of AV valves.

5. What is the condition where a blood clot blocks an artery in the lungs, causing shortness of breath, chest pain, and other symptoms?

• A. Pulmonary embolism
• B. Pneumothorax
• C. Pleural effusion
• D. Aneurysm

Correct answer: A

Rationale: The correct answer is Pulmonary embolism. Pulmonary embolism occurs when a blood clot blocks an artery in the lungs, leading to symptoms like shortness of breath and chest pain. This condition is life-threatening and requires prompt treatment. Choices B, C, and D are incorrect as they refer to different medical conditions: Pneumothorax is a collapsed lung, Pleural effusion is an abnormal accumulation of fluid around the lungs, and an Aneurysm is a bulge in a blood vessel.
