,A 42 year-old trauma patient in the ED has been intubated with a 6.5 mm oral endotracheal
tube equipped with a high-residual-volume, low-pressure cuff. The respiratory therapist
notes that a cuff pressure of 42 cm H2O is necessary to achieve a minimal occluding volume.
This would indicate that the
A. tube is not of the appropriate size.
B. pilot balloon and line are obstructed.
C. pressure manometer is defective.
D. cuff has herniated over the tip of the tube. -correct answer-tube is not of the appropriate
size.
A 44 year-old patient who suffered a cerebral vascular accident has been moved from
Neuro-ICU to the step-down unit. He becomes diaphoretic and his SpO2 suddenly drops
from 95% to 88% on a 32% tracheostomy collar. His heart rate is 115/min, respiratory rate is
42/min and his breath sounds are very diminished. The respiratory therapist is unsuccessful
in attempting to pass a 12 Fr suction catheter. The therapist should
A. increase the suction pressure to 120 mm Hg.
B. change to a 10 Fr suction catheter.
C. replace the tracheostomy tube.
D. orally intubate the patient. -correct answer-Replace the tracheostomy tube.
A 48 year-old female is admitted to the ED with diaphoresis, jugular venous distension, and

C. heart failure.
D. electrolyte imbalances -correct answer-Heart failure
A 50 kg (110 lb) patient is being mechanically ventilated with the following settings: VC, A/C,
VT 400 mL, respiratory rate 14/min, FIO2 0.60 and 10 cm H2O PEEP. The chest radiograph
demonstrates diffuse bilateral radiopacity. ABG results are: pH 7.36, PaCO2 47 torr, PaO2 50
torr, and HCO3- 28 mEq/L. The respiratory therapist should increase the
, A. PEEP.
B. FIO2.
C. expiratory time.
D. respiratory rate. -correct answer-PEEP
A 52 year-old post-operative cholecystectomy patient's breath sounds become more coarse
upon completion of postural drainage with percussion. The respiratory therapist should
recommend
A. continuing the therapy until breath sounds improve.
B. administering dornase alpha.
C. administering albuterol therapy.
D. deep breathing and coughing to clear secretions. -correct answer-deep breathing and
coughing to clear secretions.

ergometer cardiopulmonary stress procedure, the patient has a heart rate of 100/min and a
respiratory rate of 20/min. He suddenly begins to complain of chest pain and severe
shortness of breath. The respiratory therapist should
A. reduce the speed of the bike.
