NBRC EXAM, Part I Exam 2026
Questions and Answers
PATIENT ASSESSMENT:
All the following could cause capnography to go from 3 6 to 30 EXCEPT:
A. Endotracheal tube positioned in the right mainstream bronchus
B. Hyperventilation
C. pulmonary emboli
D. Hypovolemia - Correct answer-Endotracheal tube positioned in right mainstem
bronchus is a problem but the co2 reading would not change, so
ANSWER is A.
What is the target Vt for individual on mechanical ventilation - Correct answer-6-8
ml/kg (of ideal body weight) This is new strategy as of January 2015
Is the following Static OR Dynamic Compliance:
©COPYRIGHT 2025, ALL RIGHTS RESERVED 1
,Means flow throughout the respiratory system has stopped and all ventilatory
muscle activity is absent. _______ conditions can be imposed with an inspiratory
pause when a patient is sedated and mechanically ventilated. - Correct answer-
Static Compliance
Is the following Static OR Dynamic Compliance:
Flow at airway opening is zero. Mechanics are evaluated under ______ conditions,
when non-intubated patient breathes spontaneously. - Correct answer-Dynamic
Compliance
A balloon tipped flow directed catheter is positioned in the pulmonary artery with
the balloon deflated. Which of the following pressures will be measured by the
proximal lumen:
a. Cvp
b. Pap
c. Pwp
d. Map - Correct answer-ANSWER is A. Cvp = deflated/proximal lumen
Pap = deflated/distal

,Pwp = inflated/wedged
All of the following will affect the accuracy of a capnography EXCEPT
a. Long sampling line
b. Low sampling flow
c. Condensation in the tubing
d. Use of desiccant - Correct answer-Gas will pass through and out of a long
sampling line before reaching analyzer so, low sampling flow will not give you
enough information for a good reading, and condensation as a rule is always a
problem especially in analyzers. Dessicant removes moisture from the gas, which
is a good thing, so
ANSWER is D
A 1000 g neonate (normal baby is 3000 g) is stable in nicu. Which of the following
should the respiratory therapist use to monitor the neonates overall
cardiopulmonary status.
a. TcPCO2 and TcPO2 monitor
b. Arterial blood gas analysis Q4
c. SpO2 monitor
©COPYRIGHT 2025, ALL RIGHTS RESERVED 3
, d. Capillary gas analysis Q8 - Correct answer-Since the baby is stable, go less
invasive, also go continuous monitoring (not 4 hour or 8 hour), Transcutaneous
(Tc) continuous monitoring of CO2 and O2 is the best. Answer is A
A unilateral wheeze would most likely indicate which of the following.
a. Asthma
b. Atelectasis
c. Foreign body aspiration
d. Epiglottitis - Correct answer-You wouldn't have asthma on just one side
(unilateral), atelectasis would cause diminished breath sounds, with epiglottitis you
would get stridor, since you are only hearing wheezing on one side, you are
hearing it on the side where you aspirated something,
so ANSWER is C
All of the following would be associated with the presence of a pneumothorax
EXCEPT
a. Tracheal deviation
b. Dull percussion
c. Absent breath sounds
