1.Prior to taking a pulmonary artery wedge pressure (PCWP) reading, the
RT ensure that
ANS -the transducer is properly leveled and zeroed
2.The fiberoptic bronchoscope is usually preferred device during
bron- choscopy b/c its
ANS -flexibility
3.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
4.A RT is performing nasotracheal suctioning. During the procedure, the
ther- apist occludes the catheter's thumb port; there is no vacuum. The
therapist could do all of the following EXCEPT
ANS -use a longer suction catheter
5.The primary hazard of an oropharyngeal airway device is
ANS -the ot may gag or fight the device
6.While manually ventilating a pt with a bag-valve resuscitator during car-
diopulmonary resuscitation (CPR), the RT notices that the oxygen reservoir
is missing. The therapist should conclude that
,ANS -the FiO2 will most likely be less than 1.0
7.A pt with a tracheostomy tube is producing moderate amounts of thick,
tena- cious sputum. The best device for this pt would be
ANS -a heated large reservoir air-entrainment jet nebulizer
8.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?
ANS -heat moisture exchanger
9.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?
ANS -tighten all connections
10.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?
ANS -tighten all connections
11.Which of the following will alter the oxygen concentration of an air-
entrain- ment 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 set- ting-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
ANS 4 Increasing the flow setting-NO Occluding the air-entrainment
ports-YES Altering the size of the jet orifice-YES
12.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
13.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?
ANS -12-lead ECG
14.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?
ANS -SVO2
15.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?
ANS -analyze the blood sample using a CO-oximeter
16.Which of the following would be most helpful to evaluate the
effectiveness of secretion clearance therapy?
ANS -chest x-ray
17.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
18.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
19.A spontaneous breathing trial (SBT) should be terminated and the pt
re-evaluated if
ANS -the SpO2 decreases by 5%
