Q

pathophys of asthma (4)

A
  • bronchial inflammation and bronchoconstriction that affects all levels of the airway
  • increases mucus secretion
  • loss of barrier increases susceptibility to eosinophils, etc
  • loss of enzymes that typicaly breakdown inflammatory mediators

16
Q

what is the pulmonary index score (PIS)?

A

assessment tool for kids with acute asthma exacerbation

17
Q
  • Used w/ MDI to minimize systemic absorption and limit local SE
  • all ICS MDI should be used w/ this device in all patients

what device does this describe?

A

holding chambers

18
Q

what three medications can be a trigger for asthma

A

NSAIDs
BB
Aspirin

19
Q

decreases cellular migration and inhibits fluid release and accumulation of leukocytes –> reduction of inflammatory cells

what medications

A

inhaled ICS

20
Q

inhibits the action of leukotrienes, which are a family of products generated from the metabolism of arachidonic acid in leukocytes

A

leukotriene antagonists (montelukast, zafirlukast)

21
Q

stimulate B-2 receptors in airway cells to produce smooth muscle relaxation and bronchodilation caused by adenylyl cyclase activation to produce cyclic 3’5’ AMP

what medication

A

SABA

22
Q

if you see patient presenting with asthma sx and they also have a nasal polyp, what should you be suspecting

aka Sampters triad?

A

aspirin induced asthma

23
Q

how fast do SABAs work

A

5-10 minutes

24
Q

if a patient with asthma develops influenza A, which flu medication would you want to avoid giving them? why?

A

Zanamivir bc increases risk of bronchospasm

25
Q

green zone corresponds with ____ % of the best peak flow

A

80%

26
Q

yellow zone corresponds with ____ % of the best peak flow

A

50-79%

27
Q

bronchodilator that prevents sx (esp. Nocturnal asthma)

A

LABA (salmeterol, formoterol)

28
Q

anti-inflammatory; All but the mildest exacerbations should be discharged on a short course of this

A

oral steroids

29
Q

Hits B1 and B2→ long term use increases risk of cardiomyopathies!!!!

A

EPI

30
Q

which class is always used in combo with ICS, only if persistent asthma is not controlled w/ ICS

A

LABA

31
Q

Meds for pt w/ asthma + allergic rhinitis. Prophylaxis only

A

leukotriene antagonists

32
Q

side effects of this class includes

  • HA
  • Mild-flu sx
  • Aggressive behav., agitation
  • hepatic issues (which specific med?)
A

Leukotriene antagonist
hepatic– zafirlukast

33
Q

these are SE for?

  • Euphoria, energetic
  • Insomnia
  • hunger
  • cataracts
  • moon face
A

first 3 are short term SE of Oral steroids

34
Q

which med requires serum monitoring to avoid toxicities (5-15 mcg/ml) and multiple drug interactions

A

theophylline

35
Q
  • bronchodilator that improves resp. muscle endurance, PPD inhibitor which inhibits lekotriene synthesis and inflammation
  • nonselective adenosine receptor antagonist
  • requires higher doses in smokers
  • used as long-term prophylaxis in select ppl
A

theophylline
