NBRC EXAM, Part I Questions with Verified
Correct 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
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
d. Administration of epinephrine
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 .
What is the normal range for the mean pulmonary artery pressure in an adult
a. 2-6 mm Hg
b. 4-12 mmHg
c. 9-18 mmHg
d. 21-28 mmHg
Mean pulmonary artery pressure in an adult should be in the teens
so best ANSWER is C
A patient in the emergency dept has frothy secretions, moist crackles, and tachypnea.
The patient has marked dyspnea and a history of heart disease. Which of the following
should the respiratory therapist recommend.
1.suction immediately
2.administer 100% oxygen
3.place in Fowlers position
4.administer furosemide
This is an emergency, they are having heart problems, dyspnea, frothy secretions indicating
severe pulmonary edema, etc. so 100% oxygen immediately, having the patient in the
Fowlers position (an upright position) will help pull fluid down away from the lungs,
