A patient is admitted to the ED following a motor vehicle accident. On physical exam, the
respiratory therapist discovers that breath sounds are absent in the left chest with a
hyperresonant percussion note. The trachea is shifted to the right. The patient's heart rate is
45/min, respiratory rate is 30/min, and blood pressure is 60/40 mm Hg. What action should
the therapist recommend first?
Needle aspirate into the 2nd left intercostal space
All of the following strategies are likely to decrease the likelihood of damage to the tracheal
mucosa EXCEPT:
-maintaining cuff pressures between 20 and 25 mm Hg.
- using the minimal leak technique for inflation.
- using a low-residual-volume, low-compliance cuff.
- monitoring intracuff pressures.
using a low-residual-volume, low-compliance cuff.
A 52 year-old post-operative cholecystectomy patient's breath sounds become more coarse
upon completion of postural drainage with percussion. The respiratory therapist should
recommend
deep breathing and coughing to clear secretions.

A 65 kg spinal cord injured patient develops atelectasis. His inspiratory capacity is 30% of his
predicted value. What bronchial hygiene therapy would be most appropriate initially?
IPPB
A healthy adult female can exhale what portion of her forced vital capacity in the first
second?
70%
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.

A 48 year-old female is admitted to the ED with diaphoresis, jugular venous distension, and 3+
pitting edema in the ankles. These findings are consistent with
heart failure

What is normal urine output in an adult patient?

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.
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

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?

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
