Following abdominal surgery, a 70 year-old patient receives mechanical
ventilation in the ICU at the following settings: VC, A/C; VT 550 mL,
respiratory rate 14/min, FIO2 0.50 and 10 cm H2O PEEP. Bedside
monitoring results demonstrate that the PvO2 is 35 torr and the SpO2 is
90%. The patient is alert and oriented with stable vital signs. Which of the
following should the respiratory therapist recommend? - ANS ✓increase the
FiO2
The primary source of infection in the health care setting is - ANS ✓poor
handwashing techniques of personnel
A 36 year-old patient is admitted to the ED with a temperature of 38.5° C
and suspected pneumonia. The patient has no history of pulmonary
disease. Auscultation reveal medium crackles throughout both lungs.
Which of the following should be recommended for management of this
patient? - ANS ✓regular coughing and deep breathing
The respiratory therapist obtains a blood gas sample from the patient's
radial artery and applies pressure to the site for 10 minutes. After
removing any excess air from the syringe, the next step for proper handling
of the blood sample is - ANS ✓placing the syringe in an ice bath
Which of the following findings is LEAST compatible with hyperlucency as
seen on a chest x-ray? - ANS ✓increased fremitus
A spontaneous breathing trial 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, and HCO3- 24 mEq/L. The
patient's vital signs remained stable throughout the trial. Which of the

following is the most appropriate recommendation? - ANS ✓extubate the
patient
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. - ANS ✓1, 2 and 3
A 52 year-old post-operative patient's chest radiograph demonstrates
infiltrates in the posterior basal segments of the lower lobes. Which of the
following is the appropriate postural drainage position? - ANS ✓Head down,
patient prone with a pillow under hips
A 72 year-old female post stem cell transplant patient in the ICU complains
of difficulty breathing and is noted to have diffuse fluffy infiltrates on chest
X-ray. The B-type Natriuretic Peptide (BNP) test result demonstrates 700
pg/mL. What is the patient's possible condition? - ANS ✓moderate heart
failure
Following blunt chest trauma, a 35-year-old male is orally intubated and
continuous mechanical ventilation is initiated. Physical assessment of the
neck and chest reveal a midline trachea and significant reduction in
thoracic expansion of the left chest. There are diminished breath sounds in
the left lung compared to the right lung. These findings most likely indicate
which of the following? - ANS ✓Endobronchial intubation
The respiratory therapist performs the quality control procedures for the
blood gas analyzer in the NICU and notices a single data point that is 3
standard deviations from the mean value for the pH electrode. The
therapist should - ANS ✓perform another control run

A patient receiving pressure-controlled ventilation has acute
hypoventilation with an ETCO2 of 70 torr. His vital signs include: heart rate
90/min, respiratory rate 18/min, SpO2 94%. Which of the following
change(s) will address the situation?
1. Increase the pressure limit
2. Increase the sensitivity
3. Increase the mandatory rate
4. Decrease the inspiratory time - ANS ✓1 and 3 only
A 60 year-old male has just been extubated following coronary artery
bypass grafting. His chest X-ray demonstrates platelike infiltrates with
scattered densities and he is noted to have decreased chest expansion with
an increased respiratory rate. Which of the following treatments should be
recommended for this patient? - ANS ✓lung expansion therapy
A 42 year-old trauma patient in the ED has been intubated with a 6.5 mm
oral endotracheal tube equipped with a high-residual-volume, low-
pressure cuff. The respiratory therapist notes that a cuff pressure of 42 cm
H2O is necessary to achieve a minimal occluding volume. This would
indicate that the - ANS ✓tube is not of the appropriate size
A patient receives oxygen via nasal cannula at 2 L/min and has the
following ABG results: pH 7.37, PaCO2 42 torr, PaO2 80 torr, HCO3 38
mEq/L. The most likely explanation for these results is that - ANS ✓the
numbers were not reported correctly
The respiratory therapist completes oxygen rounds and checking oxygen
saturations on a number of patients. What solution would be most
appropriate for disinfecting the surface of the pulse oximeter between
patients? - ANS ✓Ethyl alchohol
Evaluation of a spontaneously breathing patient reveals tachypnea,
tracheal deviation to the right and an absence of breath sounds on the left.
The most likely etiology would be - ANS ✓left tension pneumothorax
