AND CORRECT DETAILED ANSWERS
the RT, when reviewing a flow time wave form of a patient receiving volume control ventilation, notices
the expiratory flow does not return to baseline following each mechanical breath. which of the following
actions would be appropriate? - CORRECT ANSWER-decrease mandatory rate
an intubated patient who had an abdominal surgery has been transferred to the ICU. the RT suspects the
endotracheal tube was an inadvertently repositioned during the transport. The patient is currently
receiving volume controlled mechanical ventilation. which of the following should the therapist do first
to determine the appropriateness of the position of the endotracheal tube? - CORRECT ANSWER-assess
and evaluate chest rise
The RT is performing a nasotracheal suctioning of a 45-year-old conscious male patient. during the
procedure, the patient's SpO2 falls from 95% to 89% and his heart rate rises from 82 to 118 /min. The
therapist should alter the: - CORRECT ANSWER-suction duration
the RT is assessing the pain level of a 6-year-old patient. which of the following would be most effective?
- CORRECT ANSWER-use pictograms
a 74-year-old male is admitted to the ICU after undergoing a surgery to repair a right femur fracture that
occurred during a motor vehicle accident. he experiences a sudden onset of shortness of breath and
becomes cyanotic from the waist up. the RT should recommend which diagnostic procedure? - CORRECT
ANSWER-pulmonary angiogram
a patient receiving volume controlled mechanical ventilation has blood gas data as follows:
pH - 7.28
PaCO2 - 51 torr
PaO2 - 60 torr
which of the following should the RT conclude? - CORRECT ANSWER-minute ventilation should be
increased
A patient in the ICU is connected to a chest tube drainage system when the low return volume alarm
sounds on the ventilator. significant bubbling is noted in the water seal chamber. The RT should suspect:

, a physician is examining the blood gas data on a 32-year-old patient with sepsis. Sinse sepsis leads to an
increase in O2 consumption, she asks the RT to determine the amount of oxygen being consumed by the
tissues. Which of the following calculated values should the therapist employ to determine O2
consumption by the tissues? - CORRECT ANSWER-C(a-v)O2

Vt - 600ml
The physician is worried about the adequacy of ventilation & would like to determine the dead
space/tidal volume ratio. in addition to the results of a blood gas, to what other sources should the
therapist look to provide a physician with appropriate data? - CORRECT ANSWER-capnography
