1. Which of the following is a chronic lung disease that includes conditions such as chronic bronchitis and emphysema, characterized by obstructed airflow from the lungs?

• A. Chronic obstructive pulmonary disease (COPD)
• B. Pulmonary fibrosis
• C. Asthma
• D. Pneumonia

Correct answer: A

Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic lung disease that encompasses conditions like chronic bronchitis and emphysema. These conditions lead to obstructed airflow from the lungs, causing symptoms such as cough, shortness of breath, and wheezing. Choice B, Pulmonary fibrosis, involves scarring of the lung tissue, leading to breathing difficulties but is not specifically characterized by obstructed airflow like COPD. Asthma (Choice C) is a chronic condition characterized by airway inflammation and bronchoconstriction, not always resulting in obstructed airflow. Pneumonia (Choice D) is an acute infection of the lung tissue, causing symptoms like fever, cough, and difficulty breathing, but is not a chronic condition like COPD.

2. What is a chronic lung disease that includes chronic bronchitis and emphysema?

• A. Chronic Obstructive Pulmonary Disease (COPD)
• B. Pneumonia
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: The correct answer is Chronic Obstructive Pulmonary Disease (COPD). COPD is a chronic lung condition that encompasses chronic bronchitis and emphysema, causing airflow obstruction from the lungs. Pneumonia (choice B) is an infection in the lungs, while asthma (choice C) is characterized by airway inflammation and constriction. Tuberculosis (choice D) is a bacterial infection that primarily affects the lungs but is distinct from COPD.

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 test measures the oxygen level in the blood, often used to monitor patients with respiratory or cardiovascular conditions?

• A. Pulse oximetry
• B. Arterial blood gas (ABG)
• C. Echocardiogram
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Pulse oximetry. Pulse oximetry is a non-invasive test that measures the oxygen saturation level in the blood, commonly used to monitor respiratory and cardiovascular health. Arterial blood gas (ABG) measures the levels of oxygen and carbon dioxide in the blood, providing more detailed information than pulse oximetry. Echocardiogram is an ultrasound test used to visualize the heart's structure and function, while a chest X-ray is used to visualize the structures in the chest, such as the heart, lungs, and bones.

5. What test measures the electrical activity of the heart over a 24- or 48-hour period?

• A. Holter monitor
• B. Electrocardiogram
• C. Stress test
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Holter monitor. A Holter monitor is a portable device that continuously records the heart's electrical activity over 24 to 48 hours, aiding in the diagnosis of arrhythmias and other heart conditions. Choice B, an Electrocardiogram, provides a snapshot of the heart's electrical activity at a specific point in time, not over an extended period like a Holter monitor. Choice C, a Stress test, measures how the heart responds to physical activity and is not used for continuous monitoring of electrical activity. Choice D, a Chest X-ray, is used to visualize the structures of the chest, not to measure the heart's electrical activity.
