Questions And Answers
An infant with pneumonia is placed on CPAP with the initial level is
6 cm H20. After the patient is placed on the system, the respiratory
therapist notices that the pressure falls to 2 cm H20 with each
inspiration. What should be done to correct the problem?
a. Tell the patient to relax and breath more slowly
b. Give the patient diazepam (Valium)
c. Increase the CPAP level to 8 cm H20
d. Increase the flow through the system - - -
correct answer ✅Increase the flow through the system
Explain: Decreasing pressure with inspiration indicates inadequate
gas flow. Increasing the flow should meet the patient's inspiratory
flow needs and stabilize the CPAP pressure.
A respiratory therapist is called to the ED for a 1-year-old with
difficulty breathing. Severe suprasternal, subcostal and substernal
retraction are observed. The child has a harsh, barking cough.
Stridor is present. The therapist should anticipate treatment for

Questions And Answers
a. Cystic Fibrosis
b. Pneumonia
c. Croup
d. Asthma - - -
correct answer ✅Croup
Explain: The patient has some degree of upper airway obstruction
caused by some viral illness. The barky cough is a classic finding for
patients experiencing croup.
The polysomnography sleep laboratory is full 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
d. Chest-wall and abdominal-wall impedance comparison - - -
correct answer ✅Overnight pulse oximetry
,NBRC TMC Practice with rationales
Questions And Answers
Explain: 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.
A respiratory therapist is assessing a 168-cm (5-ft 6-in), 73-kg (161-
lb), a 41-year-old female who was admitted 12 hours ago for an
aspirin overdose. The following information is obtained as the
patient breathes air:
HR 89/min
RR 15/min
BP 110/70 mm Hg
Sp02 86%
A respiratory therapist should do first.
a. Initiate oxygen at 4L/min by cannula
b. Record the results in the medical record
c. Obtain an arterial blood gas sample
d. Validate the Sp02 reading at a different site - - -
correct answer ✅Validate the Sp02 reading at a different site
, NBRC TMC Practice with rationales
Questions And Answers
Explain: The saturation may not be accurate and should be
measured at a different site.
A 47-year-old male with a BMI of 50 kg/m is undergoing a sleep
study with titration of CPAP. The patient's baseline AHI is 59. At a
CPAP level of 7 cm H20, the AHI is 9. A respiratory therapist should
recommend
a. Maintain the current level of CPAP
b. Decreasing the CPAP
c. Increasing the CPAP
d. Changing to bilevel PAP - - -
correct answer ✅Increasing the CPAP
Explain: The goal of CPAP intervention is to completely eliminate
apnea and hypopnea episodes, standard protocol is to
incrementally increase the CPAP level until this occurs.
An arterial puncture has been performed to obtain blood for
analysis of 02, C02, and pH. What is the best way to manage the
blood sample?
