Run 1 7.33 83
Run 2 7.25 86
Run 3 7.29 80
Which quality control runs indicate the machine is out of control?
A. 2 and 3
B. 1, 2, and 3
C. 1 and 2
D. 1 and 3 - ANSWER-The correct answer is : A
,Quality control data for an arterial blood gas analyzer is plotted on
a graph that has a range of 4 standard deviations (2 SD up and 2
SD down). Points on the graph show a gradual rise from below
the mean to above the mean. All points are within 2 SD of the
mean. The respiratory supervisor should
A. remove this machine from service
B. call the medical director for direction
C. monitor this machine closely
D. replace the electrodes - ANSWER-The correct answer is : C
The sudden sounding of a high-pressure ventilator alarm is noted
on a patient receiving volume controlled mechanical ventilation.
The respiratory therapist notes the endotracheal tube is at 27 cm
at the teeth and that breath sounds are absent when auscultating
the left hemithorax. The therapist should immediately
A. withdraw the endotracheal tube until breath sounds are
bilateral
B. advance the endotracheal tube until breath sounds can be
auscultated over the left chest
C. prepare for insertion of chest tubes in the left thorax
D. check the air pressure of the tube cuff - ANSWER-The correct
answer is : A

ventilation?
A. tidal volume, weight, respiratory rate
B. C(a-v)O2 and VT
C. PAO2 and tidal volume
D. VD/VT and PAO2 - ANSWER-The correct answer is : A
A female patient who is morbidly obese has an 8.0 mm
tracheostomy tube. She has been placed on an ulcer prevention
mattress in the Intensive Care Unit. Following transport to the new
bed, the nurse calls a respiratory therapist to assess her because
she is complaining of air hunger. Diffuse dry crackles are
auscultated with crepitus noted upon palpation. These findings
are most closely associated with
