A 50-year-old woman with ventilatory failure due to polymyositis has been on a
ventilator for 5 days when the physicians noted increasing endotracheal secretions and
decreased oximetry. A bronchoscopy showed abundant mucus plugs filling the bronchial

to improve mucociliary clearance. Which of the following drugs was most likely
administered?
A. 
B. 
C. 
D. 
E. 
F. 
6.
A 44-year old man presented to his physician complaining of an increasing cough
productive of yellow sputum and of a moderate some short of breath on exertion. The
man had a long history of heavy cigarette smoking, and suffered from an episode of
sustained ventricular tachycardia one year ago. Physical examination showed a patient
with shallow breathing and a barrel chest. Auscultation demonstrated wheezing and
distant heart sounds. An inhalatory therapy was ordered. A drug with which of the
following mechanism of action was most likely prescribed?
A. 
Activation of adenosine receptors
B. 
Inhibition of phospholipase A2
C. 
Activation of beta-2 receptors
D. 
Blockade of Nn and M3 receptors
E. 
Blockade of a delayed chloride channel
7.
A 46-year-old woman complained to her physician of dry mouth. The woman, recently
diagnosed with chronic obstructive pulmonary disease, started an appropriate treatment
one week previously. Which of the following drugs most likely caused the patient’s
symptom?
A. 
B. 
C. 
D. 
E. 
F. 
8.
A 43-year old woman complained to her physician of recurrent wheezing and frequent
nocturnal awakening. She also noted that wheezing was most frequent when she was
anxious and tense. The woman had been suffering from allergic rhinitis for four years and
from hyperthyroidism for one year. A diagnosis of mild allergic asthma was made. Which
of the following drug treatments would be most appropriate for a relief of her
bronchospasm?
A. 
B. 
C. 
D. 
E. 
F. 
9.
A 10-year-old girl, who has been suffering from seasonal allergic rhinitis for 3 years,
presented to the family physician with nasal itching, sneezing and running nose. The

Which of the following drugs was most likely prescribed?
A. 
B. 
C. 
D. 
E. 
10.
A15-year-old boy complained to his family physician of pain on swallowing. Physical
examination revealed white patches in the oropharynx and subsequent histology
confirmed the diagnosis of oral candidiasis. The boy, recently diagnosed with mild
persistent asthma, had started an inhalatory therapy two weeks previously. Which of the
following drugs most likely caused the patient’s candidiasis?
A. 
B. 
C. 
D.

11.
A 9-year-old boy with moderate persistent asthma was in the chest clinic for follow up
of his disease. He had been only moderately well controlled on oral sustained-release
theophylline and inhaled cromolyn daily, and inhaled albuterol “as needed”. Physical
examination showed diffuse expiratory wheezes and pulmonary function testing revealed
a peak expiratory flow rate 60% of predicted. Which of the following would be an
appropriate therapeutic conduct for this patient?
A. 
Substitute albuterol with ipratropium
B. 
Add inhaled beclomethasone to the present regimen

another drug to the present treatment. Which of the following drugs was most likely
prescribed?
A. 
B. 
C. 
D. 
E. 
13.
A 44-year-old asthmatic man was brought to the emergency room with a severe
asthma exacerbation. The patient’s FEV1 did not improve upon administration of inhaled
