1. 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?

• A. Pneumonia
• B. Tuberculosis
• C. Asthma
• D. Bronchitis

Correct answer: A

Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.

2. What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?

• A. Hypertension
• B. Hypotension
• C. Hyperlipidemia
• D. Hyperglycemia

Correct answer: A

Rationale: Hypertension, also known as high blood pressure, is a chronic condition characterized by persistently elevated pressure in the arteries. This condition increases the risk of heart disease, stroke, and other health issues. Hypotension (choice B) refers to low blood pressure and is not the correct answer. Hyperlipidemia (choice C) is high levels of fats in the blood, not related to blood pressure. Hyperglycemia (choice D) is high blood sugar levels, not directly related to elevated blood pressure.

3. Which medication relaxes the muscles around the airways, making it easier to breathe?

• A. Bronchodilator
• B. Corticosteroid
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.

4. What is the approximate stroke volume of the heart?

• A. Approximately 60 mL of blood per beat
• B. Approximately 70 mL of blood per beat
• C. Approximately 80 mL of blood per beat
• D. Approximately 90 mL of blood per beat

Correct answer: B

Rationale: The correct answer is B: Approximately 70 mL of blood per beat. The stroke volume of the heart is typically around 70 mL, indicating the volume of blood ejected from the left ventricle with each contraction. Choices A, C, and D are incorrect as they do not represent the standard approximate stroke volume of the heart, which is around 70 mL per beat.

5. What procedure is used to visualize the airways and diagnose lung disease?

• A. Bronchoscopy
• B. Thoracentesis
• C. Pulmonary function test
• D. Chest X-ray

Correct answer: A

Rationale: Bronchoscopy is the correct answer because it is a procedure specifically designed to visualize the airways and diagnose lung diseases by allowing doctors to examine the inside of the airways. Thoracentesis involves the removal of fluid from the pleural space around the lungs, not the airways. Pulmonary function tests assess how well the lungs work but do not visualize the airways directly. A chest X-ray provides an image of the lungs and surrounding structures but does not involve direct visualization of the airways.
