1. A patient with asthma experiences bronchoconstriction primarily due to which pathophysiologic
mechanism?
A. Destruction of alveolar walls
B. Chronic neutrophilic inflammation of the airways
C. IgE-mediated mast cell degranulation and smooth muscle contraction
D. Fibrotic remodeling of the pleural space
Correct Answer: C
Rationale: Asthma is characterized by reversible airway obstruction driven by type I hypersensitivity. IgE
binding to mast cells triggers degranulation and release of histamine, leukotrienes, and prostaglandins, causing
bronchial smooth muscle contraction, mucus secretion, and edema .
2. Which medication is considered the most effective long-term controller therapy for persistent asthma?
A. Albuterol
B. Inhaled corticosteroids
C. Ipratropium bromide
D. Oral prednisone
,Correct Answer: B
Rationale: Inhaled corticosteroids suppress airway inflammation, the underlying pathology of asthma. They are
first-line controller therapy for persistent asthma and reduce exacerbation frequency and severity.
3. A patient presents with acute severe asthma exacerbation. Which finding indicates impending respiratory
failure?
A. Oxygen saturation of 94% on room air
B. Respiratory rate of 24 breaths/min
C. Silent chest on auscultation
D. Use of accessory muscles
Correct Answer: C
Rationale: A silent chest indicates minimal air movement due to severe bronchospasm, a critical sign of
impending respiratory failure requiring immediate intervention.
4. Albuterol acts primarily through which mechanism?
A. Beta-2 adrenergic receptor agonism causing bronchodilation
B. Muscarinic receptor blockade
C. Leukotriene receptor antagonism
D. Mast cell stabilization
Correct Answer: A
, Rationale: Albuterol is a short-acting beta-2 agonist that relaxes bronchial smooth muscle, providing rapid
symptom relief.
5. A patient using inhaled corticosteroids should be instructed to do which of the following to prevent local
adverse effects?
A. Take the medication immediately after meals
B. Rinse the mouth after each use
C. Inhale rapidly and forcefully
D. Use a spacer only with rescue inhalers
Correct Answer: B
Rationale: Rinsing after ICS use prevents oropharyngeal candidiasis (thrush) and reduces systemic absorption
from the oral mucosa.
6. A child with asthma is prescribed montelukast. The nurse should teach the parent that this medication:
A. Provides immediate relief of acute bronchospasm
B. Blocks leukotriene-mediated inflammation and bronchoconstriction
C. Replaces the need for inhaled corticosteroids
D. Should be used only during exacerbations
Correct Answer: B
Rationale: Montelukast is a leukotriene receptor antagonist used for long-term control. It does not relieve
acute symptoms.
