Q

what are the 3 causes of air trapping?

A

(1) loss of elastic recoil in the alveolar walls
(2) overstretching and enlargement of the alveoli into air-filled spaces (bullae)
(3) collapse of small bronchioles

if SpO2 is 80%, nurse should ____

A

raise HOB and give O2 to get them to 88-92%

18
Q

why is hydration important in COPD?

27
Q

what is the action of an inhaled corticosteroid?

reduce airway inflammation

28

(4) hold breath for 10 seconds
(5) wait 5 minutes between medications
(6) rinse mouth (especially after corticosteroids)

35
Q

which meds should be administered first

A

bronchodilators before corticosteroids
