SECTION 1: RESPIRATORY DISORDERS (Questions 1–200)
Pulmonary Fibrosis (Questions 1–20)
1. A nursing student is teaching a client about their new diagnosis of
pulmonary fibrosis. The student would include which of the following in their
teaching?
A. A sputum culture may show the presence of mycobacterium
B. This is an incurable, autosomal recessive genetic disease that affects many
organs.
C. Inflammation of the mucous membranes in the airways can trigger an
attack.
D. Most clients have progressive disease with a life expectancy of less than 5
years.
Answer: C
Rationale: Pulmonary fibrosis involves chronic inflammation and scarring of
lung tissue. While the exact cause is often idiopathic, inflammation of the
mucous membranes and airways can trigger exacerbations. Option A refers to
tuberculosis. Option B describes cystic fibrosis. Option D is not universally
accurate as life expectancy varies.

2. A client with pulmonary fibrosis is experiencing increasing dyspnea at rest.
Which intervention is the priority?
A. Administer a bronchodilator
B. Provide supplemental oxygen
C. Encourage coughing and deep breathing
D. Position the client in a supine position
Answer: B
Rationale: Pulmonary fibrosis causes impaired gas exchange due to scarring
and decreased lung compliance. Supplemental oxygen is the priority to
maintain adequate oxygenation and prevent hypoxia-related complications.
3. A client with pulmonary fibrosis is prescribed pirfenidone. What is the
mechanism of action of this medication?
A. Bronchodilation
B. Antifibrotic and anti-inflammatory effects
C. Mucolytic action
D. Antibiotic prophylaxis
Answer: B
Rationale: Pirfenidone is an antifibrotic agent that slows disease progression
by reducing fibroblast proliferation and collagen deposition.

4. A client with pulmonary fibrosis is being discharged. Which instruction
should the nurse include?
A. "You should avoid all physical activity."
B. "Use supplemental oxygen as prescribed."
C. "Take antibiotics daily to prevent infection."
D. "Sleep in a supine position."
Answer: B
Rationale: Supplemental oxygen is essential to maintain oxygenation. Activity
should be balanced with rest, not eliminated.
5. A client with pulmonary fibrosis has a dry, hacking cough. What is the most
appropriate nursing intervention?
A. Administer an expectorant
B. Provide humidified oxygen
C. Administer a cough suppressant as ordered
D. Encourage deep breathing exercises
Answer: C
Rationale: A dry, non-productive cough in pulmonary fibrosis can be
distressing and exhausting. Cough suppressants may be prescribed for
comfort.

6. Which finding indicates worsening pulmonary fibrosis?
A. Improved oxygen saturation
B. Decreased dyspnea
C. Increased respiratory rate at rest
D. Weight gain
Answer: C
Rationale: An increased respiratory rate at rest indicates worsening gas
exchange and respiratory distress.
7. A client with pulmonary fibrosis is prescribed prednisone. What side effect
should the nurse monitor for?
A. Hypoglycemia
B. Weight loss
C. Hyperglycemia
D. Bradycardia
Answer: C
Rationale: Corticosteroids like prednisone can cause hyperglycemia, weight
gain, immunosuppression, osteoporosis, and insomnia.
