the tracheal mucosa EXCEPT Correct Answer: using a low residual volume, low
compliance cuff

more coarse upon completion of postural drainage with percussion. The
respiratory therapist should recommend Correct Answer: deep breathing &
coughing to clear secretions

to follow the recommended cleaning procedures using a vinegar/water
solution is that this solution will Correct Answer: retard bacterial growth
A patient who complains of dyspnea is noted to have a dry, non-productive
cough. On physical examination, breath sounds are diminished on the right,

lower lobe. The respiratory therapist should suspect that the patient is suffering
from Correct Answer: pleural effusion
