crackles, more than the right. Which of the following would
be most appropriate at this time? ...... ANSWER .......
Suction the airway
A physician has prescribed PEP therapy for his patient who
has a problem with mucus plugs. While instructing the

A physician requests the assistance of the respiratory
therapist in determining the appropriate therapy for his
postoperative patient. After assessing the patient, the
therapist records the following data: Tidal volume: 350 mL
Respirations: 24/min Vital capacity: 2.1 L On the basis of this
information, it would be appropriate for the therapist to
recommend which of the following? ...... ANSWER .......
Incentive spirometry
Several interventions have been shown to be effective in
reducing the incidence of ventilator-associated pneumonia
(VAP). Which of the following would NOT be an appropriate
intervention? ...... ANSWER ....... Routine saline lavage
through the endotracheal tube during suctioning
An orally intubated comatose patient who is being
mechanically ventilated with a volume ventilator frequently
bites the endotracheal tube. During these times, the high
pressure and the low exhaled tidal volume alarms activate.
Which of the following actions would correct the problem?
...... ANSWER ....... -Reintubate the patient with a
nasotracheal tube

A physician requests the respiratory therapist to assess the
upper airway function of a patient with a fenestrated
tracheostomy tube. The therapist should: ...... ANSWER
....... -Remove the inner cannula-deflate the cuff-plug
the outer cannula
The respiratory therapist is called to assess a 58-year-old
female who is being mechanically ventilated via volume
ventilator. Upon entering the room, the therapist finds an
extremely agitated patient in obvious respiratory distress.
The high pressure limit alarm is sounding with each breath.
The therapist begins manual ventilation and finds the
resistance to bag compression is increased. Chest
auscultation reveals absent breath sounds in the left lower
lung fields and absent breath sounds in the right middle lung
field. The therapist should now do which of the following?
...... ANSWER ....... -Withdraw the endotracheal tube
until bilateral breath sounds are heard
Physical and diagnostic findings of a trauma patient involved
in a motor vehicle accident include multiple facial and scalp
lacerations with possible head injury. The most recent chest
