1. gas exchange - ANSWER ✓ process by which O2 and CO2 are exchanged
and transported at the cellular and tissue level
2. SABAs are (PRN/scheduled) - ANSWER ✓ PRN
3. LABAs are (PRN/scheduled) - ANSWER ✓ scheduled
4. who may have an issue on Albuterol - ANSWER ✓ tachycardia or on beta
antagonist
5. why does a LABA need to be paired with a glucocorticoid - ANSWER ✓
open airways and decrease inflammation
6. how long should the patient wait between puffs of the inhaler - ANSWER ✓
one minute
7. why might a dry powder inhaler be hard for an older adult - ANSWER ✓ not
enough force to inhale
8. process of gas exchange for O2 - ANSWER ✓ atmosphere- medulla- thorax
intact, diaphragm contracts- nose- trachea- bronchi- alveoli- pulmonary
capillaries with Hgb to carry O2- perfusion to transport Hgb to cells-
metabolism
, 9. process of gas exchange for CO2 - ANSWER ✓ perfusion to transport Hgb
from cells- pulmonary capillaries with Hgb carrying CO2- alveoli- bronchi-
trachea- nose- thorax intact, diaphragm relaxes- atmosphere
10.what can cause ineffective ventilation and impair gas exchange - ANSWER
✓ broken ribs, structural defect, SCI
11.what can cause reduced capacity for gas transporation and impair gas
exchange - ANSWER ✓ reduced Hgb or RBCs
12.what can cause a diffusion limitation and impair gas exchange - ANSWER
✓ mucus, cell changes, infection
13.why can kyphosis or scoliosis cause gas exchange issues - ANSWER ✓
deceased inflation and ventilation
14.risk factors for impaired gas exchange - ANSWER ✓ age, smoking, chronic
disease, immunosuppression, reduced cognition, brain injury, immobility
15.limited oxygen reaching the alveoli is a __________ problem - ANSWER ✓
ventilation
16.limited blood flow participating in exchange is a __________ problem -
ANSWER ✓ perfusion
17.if you can get air down airways but it cannot get into the alveoli due to
secretions and mucus you have a ___________ problem - ANSWER ✓
ventilation
18.a narrowing in the trachea that limits air to the alveoli is a ___________
problem - ANSWER ✓ ventilation
19.if you can get air down into the alveoli but cannot get O2 into the blood at
the capillaries there is a ____________ problem - ANSWER ✓ perfusion
20.a pulmonary embolism is a _____________ problem - ANSWER ✓
perfusion
