Q

Metered dose inhaler (MDI) administration?

A

use spacer between MDI and mouth, exhale, squeeze just after slow inspiration starts, inhale completely, hold breath 3-5 sec, repeat x 3 with 15-30sec pause between puffs

Q

side effects of Albuterol?

A

anxiety, nervousness, headache, insomnia, dizziness, temor, palpitations, irritability

17
Q

What are three well known methylzanthines?

A

caffeine
theophylline
theobromine

18
Q

All three classes of bronchodilators have influence on which system?

A

ANS

19
Q

Atrovent (ipratroprium bromide) is in which class? What is the effect?

A

anti-cholinergic: blocks Ach receptors resulting in bronchial smooth muscle relaxation

20
Q

What are the 3 umbrellas of treatment for COPD?

A

Bronchodilators
mucolytics
antiinflammatories

21
Q

What do Mucolytics do?

A

decrease viscosity of mucous and enhance its clearance from the lung

22
Q

What is the mechanism of mucolytics?

A

break disulfide bonds of glycoprotein (mucus)

23
Q

What types of patients often use mucolytics?

A

CF

COPD accompanied by thick secretions

24
Q

Mechanism of action for Beconase/Beclomethasone? (4 elements that DJ really wants us to know!)

A

dec # of inflammatory cells moving into bronchial structures, inhibits bronchoconstriction, produces smooth muscle relaxation, dec mucus secretions.
Is an anti-inflammatory medication

25
Q

Cromolyn-sodium is effective for what?

A

prophylactic management, is an anti-inflammatory medication
