Free AMLS Respiratory Disorders Question and Answers — Questions and Answers
Question 1: Which of the following is a common symptom of chronic obstructive pulmonary disease (COPD)?
- Chest pain
- Difficulty breathing (dyspnea) (Correct answer)
- Sudden weight gain
- Muscle weakness
Correct answer: Difficulty breathing (dyspnea)
Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that makes breathing difficult. The most common and hallmark symptom of COPD is dyspnea, or shortness of breath, which often worsens with activity and over time. Other symptoms include chronic cough and wheezing, all stemming from airflow obstruction and lung damage.
Question 2: What is the primary cause of emphysema, a type of COPD?
- Viral infection
- Long-term smoking (Correct answer)
- Air pollution
- Bacterial infection
Correct answer: Long-term smoking
Long-term smoking is overwhelmingly the primary cause of emphysema, a major component of COPD. The harmful chemicals in cigarette smoke damage the alveoli (air sacs) in the lungs, leading to their destruction and loss of elasticity. This damage impairs oxygen exchange and makes breathing progressively harder, leading to chronic respiratory distress.
Question 3: What is the main treatment option for patients with asthma?
- Beta-blockers
- Inhaled corticosteroids (Correct answer)
- Antibiotics
- Chemotherapy
Correct answer: Inhaled corticosteroids
Inhaled corticosteroids are the cornerstone of long-term control treatment for persistent asthma. They work by reducing inflammation in the airways, which is a key underlying factor in asthma, thereby preventing symptoms and exacerbations. While bronchodilators provide quick relief, corticosteroids are essential for managing the chronic inflammatory process.
Question 4: Which of the following respiratory conditions is characterized by a “barrel chest”?
- Asthma
- Emphysema (Correct answer)
- Pneumonia
- Bronchitis
Correct answer: Emphysema
A 'barrel chest' is a classic physical finding often associated with advanced emphysema. It occurs due to hyperinflation of the lungs, where air becomes trapped, causing the chest wall to expand and become more rounded. This change in chest shape reflects the chronic air trapping and loss of lung elasticity characteristic of the disease.
Question 5: Which of the following conditions is caused by inflammation of the bronchi?
- Bronchitis (Correct answer)
- Pneumonia
- Tuberculosis
- Pleurisy
Correct answer: Bronchitis
Bronchitis is an inflammation of the lining of the bronchial tubes, which carry air to and from the lungs. This inflammation causes symptoms such as coughing, mucus production, and shortness of breath. It can be acute, often following a viral infection, or chronic, commonly linked to smoking and exposure to irritants.
