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
Prior 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 airentrainment ports-NO Altering the size of the jet orifice-YES - 4 Increasing the flow settingNO 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 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

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

failure who is receiving inadequate mechanical ventilation? - -metabolic
acidosis/respiratory acidosis
