four physiological features and individual may exhibit if having difficulty breathing - Answer
1. cyanosis
2. dyspnea
3. use of accessory muscles
4. nostril flaring
describe assessment findings with ineffective airway clearance - Answer -adventitious breath
sounds (wheezing, stridor, crackles)
-changes in HR and BP
-sputum
-altered rate and depth of respiration (apnea, Kussmauls, hyper/hypoventilation)
describe process of hyperinflation of a pt before suctioning - Answer involves use of Ambu
bag connected to oxygen
-squeeze bag to allow to oxygenation, giving a break between hyperinflations
hypoxia - Answer lack of oxygen in the body
symptoms of hypoxia - Answer -rapid pulse
-shallow RR
-dyspnea
-nostril flaring
-restlessness
-retractions
-cyanosis (late sign)
what laboratory values tell you the most information about effective gas exchange? - Answer
arterial blood gas
teaching steps for instructing a pt on the use of an incentive spirometer - Answer 1. sit
upright
2. put mouthpiece in mouth and close lips tightly around it
3. exhale completely
, 4. inhale as deeply as you can, watching piston rise up
5. hold breath for 10 sec, then exhale
6. repeat
purpose of turning, coughing, and deep breathing - Answer coughing loosens secretions and
