1. Which of the following is part of the treatment and management of chronic bronchitis?
A. Chemotherapy
B. Pulmonary hygiene therapy
C. Dialysis
D. Hemodialysis
Correct Answer: B. Pulmonary hygiene therapy
Rationale: Pulmonary hygiene therapy helps clear mucus and secretions, improving ventilation
in patients with chronic bronchitis.
2. Which aerosolized medication is commonly used for chronic bronchitis?
A. Anticoagulants
B. Antihistamines
C. Short-acting Beta2 agonists
D. Sedatives
Correct Answer: C. Short-acting Beta2 agonists
Rationale: Short-acting Beta2 agonists help relieve bronchospasm and improve airflow in
chronic bronchitis.
3. Bronchiectasis is best described as:
A. Collapse of alveoli
B. Chronic dilation and distortion of bronchi
C. Pulmonary embolism
D. Fibrosis of the pleura
,4
Correct Answer: B. Chronic dilation and distortion of bronchi
Rationale: Bronchiectasis involves permanent dilation and destruction of bronchial walls due to
chronic inflammation.
4. Which sputum characteristic is commonly associated with bronchiectasis?
A. Dry cough only
B. Pink frothy sputum
C. Purulent foul-smelling sputum
D. Clear watery sputum
Correct Answer: C. Purulent foul-smelling sputum
Rationale: Patients with bronchiectasis commonly produce copious purulent, foul-smelling
sputum.
5. A CT scan showing a “tree in winter” pattern is associated with:
A. Asthma
B. Pneumothorax
C. Bronchiectasis
D. Pulmonary edema
Correct Answer: C. Bronchiectasis
Rationale: The “tree in winter” appearance is a classic CT finding in bronchiectasis.
6. Mild to moderate bronchiectasis usually produces which ABG finding?
A. Metabolic alkalosis
B. Acute alveolar hyperventilation with hypoxemia
C. Respiratory acidosis without hypoxemia
D. Normal ABGs
Correct Answer: B. Acute alveolar hyperventilation with hypoxemia
Rationale: Patients often hyperventilate initially, causing low PaCO2 with associated hypoxemia.

7. Sleep apnea is defined as cessation of breathing lasting:
A. 3 seconds
B. 5 seconds
C. 10 seconds or longer
D. 30 seconds only
Correct Answer: C. 10 seconds or longer
Rationale: Sleep apnea episodes are defined as pauses in breathing lasting at least 10 seconds.
8. Central sleep apnea occurs because of:
A. Upper airway obstruction
B. Bronchoconstriction
C. Failure of the brain respiratory center
D. Pulmonary edema
Correct Answer: C. Failure of the brain respiratory center
Rationale: Central sleep apnea results from failure of the CNS to stimulate respiratory muscles.
9. Obstructive sleep apnea is caused by:
A. Lack of surfactant
B. Anatomic upper airway obstruction
C. Respiratory muscle paralysis
D. Pleural effusion
Correct Answer: B. Anatomic upper airway obstruction
Rationale: Obstructive sleep apnea occurs when airflow is blocked despite continued
respiratory effort.
10. Which physical characteristic is commonly seen in patients with obstructive sleep apnea?
A. Tall thin body habitus
B. Barrel chest
C. Short stocky neck and large tongue
D. Cyanotic nail beds only
, 4
Correct Answer: C. Short stocky neck and large tongue
Rationale: Obesity, a short thick neck, and enlarged tongue increase upper airway obstruction
risk.
11. Which diagnostic test is considered the gold standard for sleep apnea?
A. ECG
B. Pulmonary angiography
C. Sleep study (polysomnography)
D. CBC
Correct Answer: C. Sleep study (polysomnography)
Rationale: Polysomnography evaluates airflow, respiratory effort, oxygen saturation, and sleep
stages.
12. Which therapy is commonly used to manage obstructive sleep apnea?
A. Nasal CPAP
B. Antibiotics
C. Chemotherapy
D. Bronchodilator only
Correct Answer: A. Nasal CPAP
Rationale: CPAP maintains airway patency during sleep and is a primary treatment for OSA.
13. Asthma is classified as:
A. Restrictive lung disease only
B. Chronic inflammatory obstructive airway disease
C. Infectious lung disease
D. Pleural disease
Correct Answer: B. Chronic inflammatory obstructive airway disease
Rationale: Asthma is a chronic inflammatory disease characterized by reversible airway
obstruction.
