development of the pts immediate post-op treatemtn plan the sleep tech
should recommend:
a. continue current CPAP
,b. increasing CPAP
c. using supplemental O2
d. change to auto-PAP therapy - ANSWERS-a.
If a pt is nervous about CPAP therapy, it is best to recommend a:
a. anxiolytic
b. sedative - ANSWERS-a.
A sleep tech notes a. fib in a pt during bio cals. Which of the following is most
important to check in this pt:
a. resp rate
b. pulse
c. SpO2
d. mental status - ANSWERS-b.
(If the question asked which should the sleep tech check FIRST, it would be
responsiveness (mental status))
But since the question asks which is most IMPORTANT it would be pulse to
assess the need for compressions
