==================================
1-The symptoms of allergen-mediated asthma result from which

of the following ?

A-Increased release of mediators from mast cells .
B-Increased adrenergic responsiveness of the airways.
C-Increased vascular permeability of bronchial tissue.
D-Decreased calcium influx into the mast cells.
_______________________________________________
2-Acute exacerbations of asthma can be triggered by all of

the following except :

A-Bacterial or viral pneumonia.
B-Hypersensitivity reaction to penicillin.
C-Discontinuation of asthma medication .
D-Hot , dry weather.
_______________________________________________
3-A 15-year-old female is brought to the emergency department

She is breathing 30 times per minute,is unable to speak in

full sentences, and has a peak expiratory flow rate (PEFR)

<50% predicted.The preferred first-line therapy for her

asthma exacerbation is :

A-Theophylline.
B-b-agonist.
C-Corticosteroid.
D-B and c.
____________________________
4-The primary goals of asthma therapy in an adult patient

include all of the following except :

A-Maintain normal activity levels.
B-Avoid adverse effects of asthma medications.
C-prevent acute exacerbations and chronic symptoms.
D-prevent destruction of lung tissue.
_____________________________
5-Which of the following tests is used at home to assess
therapy and determine
if a patient with asthma should seek emergency care ?

A-Forced expiratory volume is one second (FEV1).
B-Forced vital capacity (FVC).
C-Total lung capacity (TLC).
D-Peak expiratory flow rate (PEFR).
________________________________
6-Chronic bronchitis is characterized by excessive mucus

production by the tracheobronchial tree,which results in

airway obstruction as a result of edema and bronchial

inflammation.

A-True
B-False
___________________
7-Airway inflammation is not crucial to development of asthma

and contributes to airway hyperresponsiveness , air flow

obstruction respiratory symptoms, and disease chronicty.
A-True
B-False
__________________________________
8-Short-acting B-agonists

(albuterol,levalbuterol,pirbuterol,metaproterenol)are best

reserved for worsening symptoms of asthma.

A-True
B-False
____________________________
9-B-Adrenergic blockers (espacially nonselective agents as

propranolol) preciptate bronchospasm and increase the dose of

B-agonist necessary to achieve bronchodilation.

A-True
B-False
____________________________
10-Corticosteroids suppress the inflammatory response and

increase airway hyperresponsiveness.

A-True
B-False
