A 36-year-old female patient who weighs is 159 cm (5 ft 2 in) tall
and weighs 136 kg (300 lb) has just undergone gastric bypass
surgery. She is brought to the PACU still intubated. The patient
has no history of pulmonary disease. A respiratory therapist
should recommend which of the following ventilator settings?
Tidal volume Mandatory rate
1. 300 mL 8
2. 400 mL 10
3. 600 mL 10
4. 500 mL 8
,Page 2 of 742
a. 1
b. 2
c. 3
d. 4 - ✔✔✔ Correct Answer > 2
Explain:
A. The resulting minute ventilation of 2.4 L/min is inadequate for
this patient.
B. Using the predicted or PBW formula for women (45.5 kg + 2.3
kg for each inch over 5 ft), the patient's PBW is 50 kg (110 lb).
Tidal volume is 8 mL/kg of PBW, which is appropriate.
C. This tidal volume is 12 mL/kg of PBW, which is too large.
D. This tidal volume is 10 mL/kg of PBW, which is too large.
While a respiratory therapist auscultates a patient's chest, the
patient repeats the words, "ninety-nine." Transmission of vocal
sounds is increased in the right lower lobe compared to the
other lung fields. Which of the following does this most likely
indicate?
A. Pleural effusion
B. Consolidation
C. Pneumothorax
,Page 3 of 742
D. Pulmonary edema - ✔✔✔ Correct Answer > Consolidation
Explain:
A. Vocal fremitus is transmission of the spoken voice to the chest
wall, detectable by auscultation or palpation. It is decreased with
pleural effusion.
B. Vocal fremitus is transmission of the spoken voice to the chest
wall, detectable by auscultation or palpation. It is increased with
lung consolidation.
C. Vocal fremitus is transmission of the spoken voice to the chest
wall, detectable by auscultation or palpation. It is decreased with
pneumothorax.
D. Vocal fremitus is transmission of the spoken voice to the chest
wall, detectable by auscultation or palpation. It is decreased with
pulmonary edema.
The polysomnography sleep laboratory is fully scheduled for
several weeks. The physician wants to know if there is another
option to determine if a patient has sleep apnea. What should be
recommended?
a. Overnight pulse oximetry
b. Nasal air flow monitoring
c. Holter monitoring for 48 hours
, Page 4 of 742
d. Chest-wall and abdominal-wall impedance comparison - ✔✔✔
Correct Answer > Overnight pulse oximetry
Explain:
A. Overnight pulse oximetry can be used to screen patients with
suspected obstructive sleep apnea. The patient's oxygen
saturation is found to decrease during apnea episodes.
B. Nasal airflow monitoring is done only during a full
polysomnography test.
C. Holter monitoring is done to evaluate a patient with cardiac
problems. A continuous electrocardiogram recording is made,
and the patient keeps an activity journal.
D. Chest-wall and abdominal-wall movement is done only during
a full polysomnography test.
A 27-year-old male patient has mild asthma. The patient's pulse
is 80/min before administration of an aerosolized bronchodilator.
The patient's pulse rises and stabilizes at 92/min during the
treatment. Which of the following should a respiratory therapist
do?
a. Terminate the treatment, and document the response in the
progress notes
b. Terminate the treatment, and notify the head nurse
