(165 lb) postoperative pneumonectomy pt:
Mode: A/C
FiO2: 0.40

✓ ~~~ Implement therapy as ordered
1. The data below are recorded for a pt being weaned from mechanical ventilation
via a 30% T-piece setup:
Prior to weaning 15 min. on T-piece
Pulse: 88/min 110/min
Respiration 16/min 27/min
pH 7.41 7.29
PaCO2 38 mmhg 56 mmhg
HCO3 25 meq/l 26 meq/l
PaO2 79 mmhg 68 mmhg
On the basis of the information, the RT should:
✓ ~~~ Reinstitute mechanical ventilation
1. Which of the following best explains the results of the chest x-ray shown to the
right?
(looking at the image the right side is fussy at the bottom)
:
✓ ~~~ There is fluid in the LEFT pleural cavity
, 2. A pt receiving 3 l/min nasal oxygen hs the following arterial blood gas results:
Ph 7.37
PaCO2 61 MMHG
HCO3 34 meq/l
PaO2 59 mmhg
The correct interpretation of these results is
✓ ~~~ Compensated respiratory acidosis with uncorrected hypoxemia
1. Which of the following should be evaluated prior to changing a pt from mechanical
ventilation to a T-piece?
✓ ~~~ Vital capacity
1. A neonate has an Apgar score of 3 and is experiencing periods of apnea. Which
of the following would be appropriate?
✓ ~~~ Perform orotracheal intubation
2. A comatose pt who needs frequent suctioning would benefit from which of the
following?
✓ ~~~ A nasopharyngeal airway

✓ ~~~ Activation of the I:E ratio alarm
1. A pt with end stage COPD has been admitted to the ED for acute exacerbation of
his condition. An arterial blood gas was drawn while the pt was breathing room air.
The pt was then placed on 3 L/min nasal oxygen and a repeat arterial blood gas was
drawn. Both sets of arterial blood gas results are as follows:
Room air 3 L/min nasal O2
Ph 7.27 7.35
PaCO2 82 mmhg 65 mmhg
HCO3 36 meq/l 35 meq/l
PaO2 42 mmhg 58 mmhg
The most appropriate change in this pt's therapy would be to:
✓ ~~~ Continue with the present therapy
2. The major goal of members participating in land/air pt transport from outlying
hospital to a tertiary care center is to:
Bring a distressed pt to a tertiary center in stable condition
✓ ~~~ Bring a distressed pt to a tertiary center in stable condition
3. A 46 year old pt has been admitted to the ED complaining of increasing
respiratory distress. An admission chest x-ray is shown to the right. On the basis of
this x-ray, which of the following therapeutic intervention would be most appropriate
at this time?
