A patient receiving oxygen at 2 L/min through a transtracheal catheter complains that
the supply tubing keeps popping off of the catheter. To correct this problem, a
,respiratory therapist should
A.decrease the flow of oxygen.
B.check the catheter for obstruction.
C.perform endotracheal suctioning.
D.tape the connection securely.
Give this one a try later!
B.√check the catheter for obstruction.
(c) B. The description suggests obstruction of the catheter due to kinking or
mucous, resulting in significant back pressure causing the supply tube to
pop off.

whether any respiratory care is indicated in the home. Which of the following suggests
the need for home apnea monitoring?

D.oxygen by cannula at 0.25 L/min
Give this one a try later!
B.√caffeine citrate daily
(c) B. Caffeine citrate is used to treat apneic conditions and indicates the
need for home apnea monitoring.

Give this one a try later!

(c) D. The integrity of the gas analysis system and its ability to return
expected results are critical elements in DLCO measurement.
A respiratory therapist is called to the bedside of an adult patient in respiratory
distress. The patient is receiving VC, A/C ventilation and the following volume-

capacity and maximally exhale to residual volume.
When extubating an adult patient, which of the following should a respiratory
therapist do FIRST?
