SECTION 1: RESPIRATORY PHARMACOLOGY - Questions 1-10
Q1: Albuterol Mechanism
The student is reviewing bronchodilators. What is the mechanism of action of albuterol?
A. Beta-2 adrenergic agonist causing bronchodilation
B. Muscarinic antagonist causing bronchodilation
C. Corticosteroid reducing inflammation
D. Leukotriene receptor antagonist
Correct Answer: A
Rationale: Albuterol is a short-acting beta-2 adrenergic agonist that relaxes bronchial smooth
muscle, causing bronchodilation. It is used as a rescue medication for acute asthma symptoms.
Ipratropium is a muscarinic antagonist. Inhaled corticosteroids reduce inflammation. Montelukast is
a leukotriene receptor antagonist. [100% CORRECT]
Q2: Ipratropium Mechanism
The student is reviewing bronchodilators. What is the mechanism of action of ipratropium?
A. Beta-2 adrenergic agonist
B. Muscarinic receptor antagonist
C. Corticosteroid
D. Leukotriene modifier
Correct Answer: B
Rationale: Ipratropium is an anticholinergic bronchodilator that blocks muscarinic receptors in the
airways, reducing bronchoconstriction and mucus secretion. It is used for COPD and asthma. [100%
CORRECT]
Q3: Inhaled Corticosteroid Adverse Effect
The student is reviewing inhaled corticosteroids. Which adverse effect is associated with fluticasone
inhaler?
,2
A. Oral thrush
B. Hypertension
C. Bradycardia
D. Hyperglycemia
Correct Answer: A
Rationale: Inhaled corticosteroids can cause oral thrush (candidiasis). Patients should rinse their
mouth with water after each use to prevent this. [100% CORRECT]
Q4: Montelukast Adverse Effect
The student is reviewing leukotriene modifiers. Which adverse effect is associated with
montelukast?
A. Neuropsychiatric effects
B. Tachycardia
C. Hypertension
D. Diarrhea
Correct Answer: A
Rationale: Montelukast can cause neuropsychiatric effects, including agitation, depression, sleep
disturbances, and suicidal thoughts. These should be reported immediately. [100% CORRECT]
Q5: Theophylline Therapeutic Range
The student is reviewing theophylline. What is the therapeutic serum range for theophylline?
A. 10-20 mcg/mL
B. 0.6-1.2 mEq/L
C. 0.5-2.0 ng/mL
D. 5-10 mg/dL
Correct Answer: A
Rationale: The therapeutic serum range for theophylline is 10-20 mcg/mL. Levels above 20 mcg/mL
can cause toxicity (tachycardia, arrhythmias, seizures). [100% CORRECT]
Q6: Omalizumab Mechanism
The student is reviewing asthma biologics. What is the mechanism of action of omalizumab?
A. Monoclonal antibody against IgE
B. Monoclonal antibody against IL-5
C. Monoclonal antibody against IL-4
D. Monoclonal antibody against IL-13
Correct Answer: A
, 3
Rationale: Omalizumab is a monoclonal antibody that binds to IgE, preventing it from binding to
mast cells and basophils. It is used for severe allergic asthma. [100% CORRECT]
Q7: Mepolizumab Mechanism
The student is reviewing asthma biologics. What is the mechanism of action of mepolizumab?
A. Monoclonal antibody against IL-5
B. Monoclonal antibody against IgE
C. Monoclonal antibody against IL-4
D. Monoclonal antibody against IL-13
Correct Answer: A
Rationale: Mepolizumab is a monoclonal antibody that binds to IL-5, reducing eosinophil production
and survival. It is used for severe eosinophilic asthma. [100% CORRECT]
Q8: Tiotropium Use
The student is reviewing COPD medications. What is the primary use of tiotropium?
A. Maintenance therapy for COPD
B. Acute asthma rescue
C. Allergic rhinitis
D. Sinusitis
Correct Answer: A
Rationale: Tiotropium is a long-acting muscarinic antagonist (LAMA) used for maintenance therapy
in COPD. It is not a rescue medication. [100% CORRECT]
Q9: Roflumilast Mechanism
The student is reviewing COPD medications. What is the mechanism of action of roflumilast?
A. Phosphodiesterase-4 inhibitor
B. Beta-2 agonist
C. Muscarinic antagonist
D. Leukotriene modifier
Correct Answer: A
Rationale: Roflumilast is a phosphodiesterase-4 (PDE4) inhibitor that reduces inflammation in COPD.
It is used to reduce exacerbations in patients with severe COPD. [100% CORRECT]
Q10: Zafirlukast Mechanism
The student is reviewing leukotriene modifiers. What is the mechanism of action of zafirlukast?
