NBRC EXAM, Part I Questions and
Answers Already Passed
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 ✔✔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 ✔✔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. ✔✔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. ✔✔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 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 ✔✔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 ✔✔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 ✔✔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 ✔✔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
