, A patient on VC ventilation demonstrates auto-PEEP on ventilator graphics. Which of the
following controls, when adjusted independently, would increase expiratory time?
1. Tidal volume
2. Respiratory Rate
3. Inspiratory flow
4. Sensitivity
1, 2, and 3
Which of the following would be the most appropriate therapy for a dyspneic patient who has
crepitus with tracheal deviation to the left and absent breath sounds on the right?
insert a chest tube
Following cardiac surgery, a 55 year-old patient has the following ABG results:
pH 7.50, PaCO2 30 torr, PaO2 62 torr, HCO3 25 mEq/L, SaO2 92%, HB 14 g/dL, BE +2.
Venous blood gas results are pH 7.39, PvCO2 43 torr, PvO2 37 torr, and SvO2 66%.
Calculate the patient's C(a-v)O2.

A patient on VC, SIMV with a VT of 500 mL has a PIP of 25 cm H2O, Pplat of 15 cm H2O
and PEEP of 5 cm H2O. What is the patient's static lung compliance?
VT/Plat-PEEP
Immediately after extubation of a patient in the ICU, the respiratory therapist observes
increasing respiratory distress with intercostal retractions and marked stridor. The SpO2 on
40% oxygen is noted to be 76%. Which of the following would be most appropriate at this
time?
Reintubation
Which of the following patients would most likely benefit from pressure support ventilation?
A. An intubated patient with an absent respiratory drive.
B. A patient on SIMV with a mandatory rate of 12/min and total rate of 24/min.
C. A patient with acute lung injury.
, D. A patient who requires short-term post-operative ventilatory support.
B. A patient on SIMV with a mandatory rate of 12/min and total rate of 24/min.
A patient receiving mechanical ventilation has developed a temperature of 99.9° F with
purulent secretions over the last 12 hours. The respiratory therapist has also noted a steady
increase in peak inspiratory pressure. What initial recommendation should be made to
address these changes?
Obtain a sputum gram stain
Which of the following information may be obtained from a FVC maneuver during bedside
pulmonary function testing?
1. FEV1
2. PEFR
3. FRC
4. RV
1 and 2
The respiratory therapist provides education for a patient who is being discharged home on
aerosol therapy. The most important reason for the patient to follow the recommended
cleaning procedures using a vinegar/water solution is that this solution will
Slow the growth of bacteria
A patient who complains of dyspnea is noted to have a dry, non-productive cough. On
physical examination, breath sounds are diminished on the right, tactile fremitus is decreased
and there is dullness to percussion over the right lower lobe. The respiratory therapist should
suspect that the patient is suffering from
Pleural Effusion
Which of the following suction catheters would be appropriate to use for a patient with a size
8.0 mm ID endotracheal tube?
12Fr
8/2(x3)=12
A patient who is receiving continuous mechanical ventilation is fighting the ventilator. His
breath sounds are markedly diminished on the left, there is dullness to percussion on the left,
and the trachea is shifted to the left. The most likely explanation for the problem is that
the endotracheal tube has slipped into the right main stem bronchus.
, The respiratory therapist notes a developing hematoma after an arterial blood gas was drawn
from the right radial artery. The immediate response is to
apply pressure to the site
A patient's breathing pattern irregularly increases and decreases and is interspersed with
periods of apnea up to 1 minute. Which of the following conditions is the most likely cause of
this problem?
Elevated intracranial pressure
What is normal urine output in an adult patient?
40 mL/hr
A spontaneous breathing term-71trial is initiated on an intubated, awake, and alert 70 kg (154
lb) patient.
After 40 minutes on an FIO2 of 0.30, ABG results are as follows:
pH 7.39
PaCO2 44 torr
PaO2 85 torr
HCO3- 24 mEq/L.
The patient's vital signs remained stable throughout the trial. Which of the following is the
most appropriate recommendation?
Extubate
After assisting with bronchoalveolar lavage and lung biopsy on a mechanically ventilated
patient, the respiratory therapist notes the activation of a high pressure alarm. Peak
inspiratory pressure has increased from 32 cm H2O before the procedure to 45 cm H2O after
the procedure. Possible causes for the increased pressure include
1. bronchospasm.
2. pneumothorax.
3. pulmonary hemorrhage.
