NBRC EXAM, Part I 2025 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 - 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:

,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
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.
What should you recommend FIRST for a patient with multifocal pvc's
a. Administration of lidocaine
b. Administration of 100% oxygen
c. Administration of atropine
d. Administration of epinephrine - ANSWER✔✔-Multiple pvc's coming from multiple locations
(multifocal) is a real problem and you should administer oxygen FIRST, so ANSWER is B. lidocaine
will help reduce irritability of heart and help with pvc's but would not be first option, atropine is
used for bradycardia and cardiac irregularities but not pvc's, epinephrine is emergency drug not for
pvc's but more for pulseless ventricular tachycardia or ventricular fibrilation where heart is not
responding .
