1. Which of the following is the most common trigger for asthma
exacerbations in adults?
A. Dust mites
B. Respiratory viral infections
C. Pollen
D. Exercise
Respiratory viral infections, particularly rhinovirus, are the leading
triggers of asthma exacerbations in adults.
2. A 10-year-old child presents with wheezing episodes only during
exercise. What is the most likely diagnosis?
A. Chronic bronchitis
B. Exercise-induced bronchoconstriction
, C. COPD
D. Cystic fibrosis
Exercise-induced bronchoconstriction is characterized by transient
airway narrowing during or after exercise.
3. Which of the following is considered a hallmark feature of asthma on
spirometry?
A. Restrictive pattern
B. Normal FEV1/FVC ratio
C. Reversible airflow obstruction
D. Fixed obstruction
Asthma typically shows reversible obstruction, demonstrated by an
increase in FEV1 after bronchodilator administration.
4. According to GINA guidelines, what is the first-line treatment for
intermittent asthma in adults?
A. Daily inhaled corticosteroid
B. As-needed low-dose inhaled corticosteroid-formoterol
C. Leukotriene receptor antagonist
D. Long-acting beta-agonist only
GINA recommends as-needed ICS-formoterol for symptom relief in
intermittent asthma rather than SABA alone due to safety and
efficacy.
5. Which immunoglobulin is primarily involved in allergic asthma?
A. IgM
, B. IgA
C. IgE
D. IgG
IgE mediates allergic responses by binding to allergens and
triggering mast cell degranulation.
6. A patient’s peak expiratory flow varies more than 20% during the day.
This suggests:
A. COPD
B. Pulmonary fibrosis
C. Uncontrolled asthma
D. Normal variation
Significant diurnal variation in peak flow is characteristic of asthma
and indicates poor control.
7. Which of the following is a long-term controller medication for
asthma?
A. Albuterol
B. Inhaled corticosteroid
C. Epinephrine
D. Oxygen
Inhaled corticosteroids reduce airway inflammation and are the
mainstay for long-term asthma control.
8. A 35-year-old patient presents with chronic cough and normal
spirometry. What type of asthma should be considered?
, A. Exercise-induced asthma
B. Allergic asthma
C. Cough-variant asthma
D. Occupational asthma
Cough-variant asthma presents primarily with cough rather than
wheezing and may have normal baseline spirometry.
9. Which of the following statements about asthma in pregnancy is
correct?
A. Asthma always worsens during pregnancy
B. Most women remain stable, but uncontrolled asthma increases
maternal and fetal risks
C. Inhaled corticosteroids are contraindicated
D. Short-acting beta-agonists should be avoided
Maintaining asthma control with appropriate medications is crucial
to reduce maternal and fetal complications.
10. What is the primary mechanism of action of leukotriene
receptor antagonists in asthma?
A. Beta-2 adrenergic stimulation
B. Blocking leukotriene receptors to reduce inflammation and
bronchoconstriction
C. Corticosteroid receptor activation
D. Mast cell stabilization
