NBRC EXAM, PART I 2026 ACTUAL
QUESTIONS WITH VERIFIED
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 - 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 -
ANSWER-6-8 ml/kg (of ideal body weight) This is new strategy
as of January 2015
Is the following Static OR Dynamic Compliance:
,2 | Page
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. - 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. - 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 - 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 - 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
d. Capillary gas analysis Q8 - 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
, 4 | Page
A unilateral wheeze would most likely indicate which of the
following.
a. Asthma
b. Atelectasis
c. Foreign body aspiration
d. Epiglottitis - 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
d. Respiratory distress - ANSWER-With pneumothorax you
would hear a high pitch hyperresonnance, breath sounds would
be absent, and respiratory distress could be present. Dull
percussion would NOT be present,
so ANSWER is B.
