calibrated to a PaO2 of 150 mmHg. Most acceptable action? - - ANS✔️--Recalibrate the analyzer
to accommodate this unusual value
An adult pt is orally intubated and receiving continuous MV. While performing a routine cuff
pressure measurement, the RT observes that the cuff pressure monometer's indicator needle
continuously reads zero. No vent alarms are activated and the pt appears to be resting. The RT
should do: - - ANS✔️--Replace cuff manometer

which of the following would be most appropriate to evaluate the effectiveness of therapy? - -

cmH2O was recorded at the time of initial assessment. The most likely finding of this cuff
pressure is: - - ANS✔️--The pt is at high risk for aspiration

therapist consider first before recommending aggressive care for this pt? - - ANS✔️--DNR/DNI
status
An RT is asked to assess a COPD pt is in a pulmonary rehab program. During the interview, the
pt tells the therapist that he has been working with a resistive training device for 2 weeks and that
he is able to tolerate the device for 15 mins. What should the therapist do? - - ANS✔️--Insert a
smaller restrictive orifice in the device
A physician has requested that the RT instruct an outpatient who is enrolled in a pulmonary
rehab program on the proper cleaning and disinfection of his RT equipment. The therapist should
explain to the pt that the primary purpose for - - ANS✔️--Reduce the spread of infection
