the home. Which of the following suggests the need for home
apnea monitoring?
A.albuterol aerosol every 4 hours prn
B.√caffeine citrate daily
C.APGAR scores of 3 and 4
D.oxygen by cannula at 0.25 L/min - ANSWER-B.√caffeine
citrate daily
Rationale; (c) B. Caffeine citrate is used to treat apneic
conditions and indicates the need for home apnea
monitoring.
A DLCO measuring device requires evaluation after being taken
out of service because of erroneous values. Which of the
following is critical to evaluate?
A.linearity of pressure drops
B.verification of shutter response
C.verification of He percentage
,3|Page
D.linearity of analyzed gas concentrations - ANSWER-
D.√linearity of analyzed gas concentrations
Rationale; (c) D. The integrity of the gas analysis system and
its ability to return expected results are critical elements in
DLCO measurement.
An adult patient is receiving PC, SIMV and the following data
are observed:
FIO2 0.80
Mandatory rate 15
Spontaneous rate 32
Set inspiratory pressure 20 cm H2O
PEEP 10 cm H2O
SpO2 92%
On inspection, the patient demonstrates suprasternal retractions
during spontaneous breaths. Which of the following should a
respiratory therapist do NEXT?
, 4|Page
A.Decrease the rise time setting.
B.Switch to A/C mode.
C.Increase the FIO2 to 0.90.
D.Change set inspiratory pressure to 25 cm H2O. - ANSWER-
B.√Switch to A/C mode.
Rationale; (c) B. The suprasternal retractions are indicative
of increased work of breathing and may be resolved by
changing the mode to A/C. The respiratory rate may also
come down.
Which of the following is the most significant factor leading to
the development of tracheomalacia?
A.cuff pressure
B.trauma during intubation
C. intracuff volume
D. tube length - ANSWER-A.√cuff pressure
