C&S TMC EXAM TWO QUESTIONS WITHCORRECT DETAILED ANSWERS
jPrior to taking a pulmonary artery wedge pressure (PCWP) reading, the RT ensure that: - -the
transducer is properly leveled and zeroed
The fiberoptic bronchoscope is usually preferred device during bronchoscopy b/c its: - -flexibility
The capnograph tracing above was obtained from a mechanically ventilated pt. On the basis of this
tracing, the RT should: - -check the exhalation valve
A RT is performing nasotracheal suctioning. During the procedure, the therapist occludes the catheter's
thumb port; there is no vacuum. The therapist could do all of the following EXCEPT - -use a longer
suction catheter
The primary hazard of an oropharyngeal airway device is: - -the ot may gag or fight the device
While manually ventilating a pt with a bag-valve resuscitator during cardiopulmonary resuscitation (CPR),
the RT notices that the oxygen reservoir is missing. The therapist should conclude that: - -the FiO2 will
most likely be less than 1.0
A pt with a tracheostomy tube is producing moderate amounts of thick, tenacious sputum. The best
device for this pt would be: - -a heated large reservoir air-entrainment jet nebulizer
Which of the following humidity devices is the most economical choice for use in an intubated,
mechanically ventilated pt who only needs short-term ventilation? - -heat moisture exchanger
The RT noticed that the CPAP pressure indicated on the low pressure monitor is consistently less than
the preset CPAP of an infant's nasal CPAP system. Which of the following should the therapist do FIRST to
correct this problem? - -tighten all connections
While the RT is checking the oxygen setup of a pt on a 2L/min nasal cannula, the pt complains of not
being able to detect any oxygen flow from the cannula. Which of the following actions would be
appropriate? - -tighten all connections
Which of the following will alter the oxygen concentration of an air-entrainment mask? 1 Increasing the
flow setting-YES Occluding the air-entrainment ports-YES Altering the size of the jet orifice-YES 2
Increasing the flow setting-NO Occluding the air-entrainment ports-YES Altering the size of the jet orifice-
NO 3 Increasing the flow setting-YES Occluding the air-entrainment ports-NO Altering the size of the jet
orifice-YES - 4 Increasing the flow setting-NO Occluding the air-entrainment ports-YES Altering the size of
the jet orifice-YES
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? - -
reposition the catheter
, A 65-year old asian female has just been admitted to the ED. Through an interpreter, it is learned that
the pt is complaining of palpitations and chest discomfort. What would be indicated? - -12-lead ECG
A critically ill pt with hypovolemic shock is being monitored in the ICU. Measurement of which of the
following would indicate if tissue hypoxia is present? - -SVO2
A 27 year old male has been admitted to the ED after he was found unconscious in the bedroom closet
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? - -analyze the blood sample using a CO-oximeter
Which of the following would be most helpful to evaluate the effectiveness of secretion clearance
therapy? - -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? - -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: - -small airway obstruction
A spontaneous breathing trial (SBT) should be terminated and the pt re-evaluated if: - -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? - -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? - hypovolemia
If the PETCO2 is 22 mm Hg and the dead space to tidal volume ratio (VD/VT) is , the resulting PaCO2 is
approximately : - -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? - -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
3 Idiopathic Pulmonary Fibrosis- NO COPD-YES Anemia-NO Pulmonary Vascular disease-YES
4 Idiopathic Pulmonary Fibrosis-YES COPD-YES Anemia-YES Pulmonary Vascular disease-NO - 1 Idiopathic
Pulmonary Fibrosis- YES COPD-YES Anemia-YES Pulmonary Vascular disease-YES
