I am providing you the sample Questions of RRT Exam of National Board for Respiratory Care NBRC

NBRC RRT Exam sample Questions

1. An oropharyngeal airway is placed in a lethargic patient to maintain a patent airway. The patient begins to cough and gag. The respiratory therapist should?
A. Reassure the patient
B. Continue to monitor the patient
C. Remove the oropharyngeal airway
D. Intubate the patient

A. Incorrect. Reassuring the patient will have no effect on the patient’s gag reflex.
B. Incorrect. The oropharyngeal airway must be removed before the patient gags, vomits, and aspirates.
C. Correct. Oropharyngeal airways should only be placed in unconscious or heavily sedated patients.
D. Incorrect. Intubation is not indicated.

2. Immediately following endotracheal intubation a disposable calorimetric CO2 detector changes color from purple to yellow. This color change most likely indicates the ETT is?
A. In the esophagus
B. In the right mainstem bronchus
C. In the airway
D. Kinked

A. Incorrect. Esophageal intubation would reveal a purple color, indicating 0% CO2.
B. Incorrect. Disposable calorimetric CO2 detectors cannot distinguish right or left mainstem intubation.
C. Correct. A yellow appearance indicates the presence of approximately 5% carbon dioxide.
D. Incorrect. A kinked ETT would not allow any ventilation or gas exchange. As a result, the ETCO2 detector would remain purple.

3. Which of the following devices maintains patency of the stoma following decanulation?
A. Nasopharyngeal airway
B. Oropharyngeal airway
C. Trachesotomy button
D. Trans tracheal catheter

A. Incorrect
B. Incorrect
C. Correct. A tracheostomy button is often used to maintain the potency of the stoma after a patient has been decannulated.
D. Incorrect

4. Which of the following steps during manual bag mask ventilation will help ensure the highest delivered oxygen level?
A. Use a flow rate of 10 to 15 LPM
B. Deliver breath over 1 second
C. Use bag with an oxygen reservoir
D. All of the above

The correct answer is D. all of the above. All of these steps will help ensure the highest delivered oxygen level.

5. Contraindications to LMA insertion include?

A. Conscious or semi-conscious patients
B. Patients with a risk of aspiration
C. Patients who are spontaneously breathing
D. Both A and B

The correct answer is D.

Practice Question
What is the estimated heart rate of this ECG?
75
60
50
100

The correct answer is 75. In the example above, there are about 4 large boxes between each R wave. To estimate the heart rate divide 300 by 4 to get the answer 75 beats per minute.

Practice Question
Spiked or peaked T waves on an ECG may be due to?
Hyperkalemia
Hypokalemia
Metabolic alkalosis
Normal finding
The Correct answer is: Hyperkalemia

Practice Question
A patient’s bed in the ICU is raised to provide routine care. The patient has a pulmonary artery catheter (PAC) in place and the transducer is attached to an IV pole next to the bed. What effect will this have on the patients CVP?

No effect
It will cause a false high reading
It will cause a false low reading
It will cause PVC’s
The correct answer is: It will cause a false low reading.

Practice Question
A patient in the cardiac ICU has a pulmonary artery catheter in place. The patient is edematous and has a CVP reading of 12. The patient most likely has?
Shock
Hypovolemia
Hypervolemia
This CVP is normal

The correct answer is: Hypervolemia.
