C&S TMC EXAM TWO(print)
Prior to taking a pulmonary artery wedge pressure (PCWP) reading, the RT ensure that: - ANS -the
transducer is properly leveled and zeroed
The fiberoptic bronchoscope is usually preferred device during bronchoscopy b/c its: - ANS -flexibility
The capnograph tracing above was obtained from a mechanically ventilated pt. On the basis of this
tracing, the RT should: - ANS -check the exhalation valve

thumb port; there is no vacuum. The therapist could do all of the following EXCEPT - ANS -use a longer
suction catheter

being able to detect any oxygen flow from the cannula. Which of the following actions would be
appropriate? - ANS -tighten all connections

While assessing a pt who is receiving oxygen via transtracheal catheter, the ot complains of a persistent,
nonproductive cough and tracheal irritation. The appropriate action at this time would be what? - ANS -
reposition the catheter

of his home following a house fire. He is currently receiving supplemental oxygen via a non rebreather
mask. An arterial blood gas sample is obtained. The values are as follows: pH 7.22 PaCO2 45 mm Hg
PaO2 345 mm Hg HCO3- 118 mEq/L SaO2 100% Which of the following would be most appropriate at
this time? - ANS -analyze the blood sample using a CO-oximeter
Which of the following would be most helpful to evaluate the effectiveness of secretion clearance
therapy? - ANS -chest x-ray
A 46 year old male is presented to the RT clinic with complaints of cough, night sweats, and loss of
appetite. The pt has a history of IV drug abuse and hep B. The therapist recommended? - ANS -tuberculin
skin test
, The PFT results of an adult female are as follows: Measured Predicted %Predicted FVC(L): 2.63 3.11 84
FEV1(L): 1.58 2.28 69 FEV1/FVC(%): 60 73 FEF25%-75%(L/Sec): 0.59 2.56 23 PEF (L/Sec): 4.90 5.78 85 On
the basis of these data, the correct interpretation is: - ANS -small airway obstruction
A spontaneous breathing trial (SBT) should be terminated and the pt re-evaluated if: - ANS -the SpO2
decreases by 5%
Shortly after administration of a sedative to a struggling and combative mechanically ventilated pt, the
RT noticed a significant decrease in pulmonary compliance. Which of the following could explain the
change? - ANS -a pneumothorax has occurred
Following the initiation of pulmonary artery pressure monitoring for an adult male being mechanically
ventilated, the following data is recorded: PAWP: 24 mm Hg C(a-v)O2: 2-4 vol% These results are most
likely associated with which of the following? - ANS hypovolemia
If the PETCO2 is 22 mm Hg and the dead space to tidal volume ratio (VD/VT) is , the resulting PaCO2 is
approximately : - ANS -45 mm Hg
Which of the following acid-base disorders would most likely be present in a pt with renal failure who is
receiving inadequate mechanical ventilation? - ANS -metabolic acidosis/respiratory acidosis
Pts with which of the following conditions are more likely to exhibit a lower than predicted carbon
monoxide diffusing capacity (DLCO)?
1 Idiopathic Pulmonary Fibrosis- YES COPD-YES Anemia-YES Pulmonary Vascular disease-YES
2 Idiopathic Pulmonary Fibrosis- YES COPD-NO Anemia-YES Pulmonary Vascular disease-NO
