What are the 3 characteristics of Asthma - CORRECT
ANSWER>>>>Bronchoconstriction
Airway Inflammation
Reversible airflow limitation
Which inhaled anticholinergic is best used for asthma pt. w/an intolerance to beta
agonist or w/ bronchospasms due to beta blocker meds? - CORRECT
ANSWER>>>>Ipratropium Bromide
What is the primary tx for pt. w/moderate to severe asthma exacerbations who do not
respond promptly and completely to SABA? - CORRECT ANSWER>>>>Systemic
Corticosteroids
Which bacterial infections predispose exacerbations of asthma - CORRECT
ANSWER>>>>M. Pneumoniae and C. Pneumoniae
Is routine use of antimicrobials recommended for acute exacerbations of asthma -
CORRECT ANSWER>>>>No, only use when likelihood of acute bacterial respiratory
tract infection
Name short acting beta agonist - CORRECT ANSWER>>>>albuterol, levalbuterol,
bitolerol, pirbuterol, terbutaline
What does a SABA do? - CORRECT ANSWER>>>>acts directly by relaxing bronchial
smooth muscles.
What do long-term pharmacologic agents accomplish for asthma pt. - CORRECT
ANSWER>>>>act primarily to attenuate airway inflammation.
Why take long-term pharmacologic agents for asthma daily? - CORRECT
ANSWER>>>>to achieve and maintain control of persistent asthma independent of
symptoms.
What does the NAEPP recommend as the cornerstone of daily treatment of persistent
asthma? - CORRECT ANSWER>>>>daily anti-inflammatory therapy with inhaled
corticosteroids
,Role of corticosteroids with asthma - CORRECT ANSWER>>>>Reduce inflammation
(acute and chronic) = improved airflow, decreased airway hyper-responsiveness and
fewer asthma exacerbations, and potentiate the action of beta-adrenergic agonist.
1st. line treatment agent for all pt w/persistent asthma (long term controller) -
CORRECT ANSWER>>>>Inhaled Corticosteroids
How often to most patient use inhaled corticosteroids? - CORRECT
ANSWER>>>>Twice daily to provide adequate control.
How long can it take to see maximum response of inhaled corticosterioids? - CORRECT
ANSWER>>>>Months

ANSWER>>>>1-2 mg/kg/day.
Can be either a single dose or divided BID.
MAX 60 mg/day
Dose of oral corticosteroids for adults during exacerbation of asthma - CORRECT
ANSWER>>>>40-60 mg/day
either as a single dose of divided BID
Duration of treatment of oral corticosteroids for asthma exacerbation - CORRECT
ANSWER>>>>3-10 days or until symptoms resolve
(no evidence that tapering dose of PO steroids prevents relapse)

CORRECT ANSWER>>>>Alternate days rather than daily treatment.
What additional medications are required to be given concurrent with systemic
corticosteroids to prevent corticosteroid induced bone mineral loss? - CORRECT
ANSWER>>>>Vitamin D and Calcium
Should systemic corticosteroids be rapidly discontinued? - CORRECT
ANSWER>>>>No, to prevent adrenal insufficiency
Name some mediator inhibitors to treat asthma - CORRECT ANSWER>>>>Cromolyn
sodium and nedocromil
, What is the mechanism of action of mediator inhibitors? - CORRECT
ANSWER>>>>prevent asthma symptoms, improve airway function in pt w/mild
persistent of exercise induce asthma
When are mediator inhibitors effective? - CORRECT ANSWER>>>>Before allergen
exposure or exercise
Do not relieve asthmatic symptoms once present.
Name the Long acting beta 2 agonist (LABA) for asthma - CORRECT
ANSWER>>>>Salmeterol and Formoteol
How are LABA's delivered? - CORRECT ANSWER>>>>dry powder
What are LABA's used for - CORRECT ANSWER>>>>Long term prevention of asthma
symptoms
Nocturnal symptoms
Prevention of exercise induced bronchospasm
Should LABA be used as monotherapy - CORRECT ANSWER>>>>NO
linked to fatal asthma when used alone
has no anti-inflammatory effects- so use w/a corticosteroid.
What does LABA + low or medium dose of corticosteroids given together provide for the
patient. - CORRECT ANSWER>>>>The equivalent to what would be if doubled the
inhaled corticosteroid.
Name the action of anticholinergic agents, short acting muscarinic agents (SAMA) and
long acting muscarinic agents (LAMA) - CORRECT ANSWER>>>>Reverse vagally
medicated bronchospasm but NOT allergen or exercise induced broncospasms
Is Ipratropium bromide (SAMA) as effect as a SABA for relief of acute bronchospasm -
CORRECT ANSWER>>>>No
What is the benefit to adding Tiotropium to therapy bronchodilator (salmeterol) or
inadequately controlled low-dose inhaler. - CORRECT ANSWER>>>>Improves lung
function and reduces frequency of asthma exacerbations.
Name the phosphodiesterase inhibitor used for asthma - CORRECT
ANSWER>>>>theophylline
What is theophylline used for in a pt w/ asthma? - CORRECT ANSWER>>>>mild
bronchodilation
What is the mechanism of action of theophylline for asthma - CORRECT
ANSWER>>>>anti-inflammatory and immunodilator properties which enhance
mucociliary clearance and strengthen diaphragmatic contractility.
