THERAPIST MULTIPLE-CHOICE
EXAMINATION: PRACTICE TEST (PART
1) QUESTIONS AND ANSWERS
A 70-kg (154-Ib) male patient is receiving mechanical ventilation. The respiratory
therapist notes the patient'sSpO, drops from expanding more than the left, 97% to 86%.
The right luno is with clear breath Sounds on the right but absent breath sounds on the
left. The patient's ET tube is taped at the 29-m mark at the lip. Which of the following
should the respiratory therapist do at this time?
A. Withdraw the tube to the 24-cm mark
B. Recommend an immediate chest x-ray
C. Advance the ET tube 2 cm
D. Obtain immediate ABG levels A 70-kg - ANSWER-A
Which one of the following sets of ABG measure. ments would indicate compensated
respiratory acidosis?
A. pH 7.26, PCO, 60 torr, PO, 68 torr, HCO, 26 mEg/L, BE 0
B. pH 7.42, PCO, 39 torr, PO, 87 torr, HCO; 22 mEq/L, BE -1
C. pH 7.25, PCO, 61 torr, PO, 75 torr, HCO, 26 mEq/L, BE +1
D. pH 7.37, PCO, 58 torr, PO2 60 torr, HCO, 31 mEg/L, BE +8 - ANSWER-D
The following data have been collected on a 75-ko (165 Ib) male patient receiving
volume-controlled ventilation:
VT 600 mL pH 7.29
Mode SIMV PaCO2 50 torr
Ventilator rate 4/min PaO2 72 torr Spontaneous rate 20/min HCO3 26 mEg/L FIO2 0.35
BE +1
On the basis of these data, which of the following should the respiratory therapist
recommend?
A. Increase the Vr to 650 mL
B. Increase the FiO, to 0.40
C. Increase the ventilator rate to 8/min
D. Change to assist-control mode at a rate of 15/min - ANSWER-C
The following data have been collected on a patient receiving continuous mechanical
ventilation:
1:00 PM 3:00 PM
, Delivered Vt. 600 ml 600 ml
Peak airway 44 cm H2O 52 cm H20
pressure
Static airway 25 cm H20 33 cm H20
pressure
Inspiratory flow 40 L/min 40 L/min
PEEP 5 cm H20 5 cm H20
Which of the following is the best interpretation of these data?
A. The peak airway pressure increased as a result of increased airway resistance.
B. The peak airway pressure increased as a result of decreased lung compliance.
C. The patient's lung compliance is improving
D. The patient's dynamic compliance is increasing - ANSWER-B
Tracheal secretions tend to dry out in an intubated patient when inspired air has which
of the following characteristics?
A. A water vapor pressure of 47 mm Hg
B. 50 mg of particulate water/L of gas
C. An absolute humidity of 24 mg/L of gas
D. 44 mg of particulate water/L of gas - ANSWER-C
It is important to monitor plateau pressure in a patient receiving mechanical ventilation
because it best reflects
A. Lung compliance
B. PaO2
C. PaCO2
D. ICP - ANSWER-A
The respiratory therapist palpates no pulse on a patient, but the ECG monitor shows
QRS complexes on the tracing. The therapist should
A. Get a stat ABG
B. Recommend defibrillation at 250 J
C. Begin cardiac compressions
D. Recommend cardioversion at 120 J - ANSWER-C
A patient is receiving volume-controlled ventilation, and the low-pressure alarm
suddenly sounds. The corrective action is to
A. Suction the patient
B. Begin manual ventilation
C. Increase the flow
D. Determine whether the patient is disconnected from the ventilator - ANSWER-D
