NBRC TMC Practice Exam Questions
#1| 2024-2025 100% Accurate With
Correct Answers With Rationale


Multiple Choice
A Hospital Has An Extremely Low Incidence Of Ventilator-Associated Pneumonia.
To Which Of The Following Reasons May This Be Attributed?
A. Periodic Discontinuation Of Sedation
B. Use Of Respiratory Precautions With The Population
C. Diversion Of Infectious Patients To Other Facilities
D. Broad Use Of Prophylactic Antibiotics


ANS: A.
The Incidence Of Ventilator-Associated Pneumonia, Or VAP, Is Lowered By Using
A Closed System Suction Catheter, Periodically Discontinuing Sedation, Keeping The
Patient And Semi-Fowler's Position, And Proper Handwashing Among Caregivers.
All Are Correct.


A Pressure-Volume Loop Ventilator Graphic Shows No Rise In Pressure For The
First 200 Ml Of Delivered Volume. The Therapist Should
A. Increase Inspiratory Flow Rate
B. Increase PEEP
C. Decrease Tidal Volume
D. Decrease Inspiratory Flow Rate


ANS: B.
In This Question The Description Of The Pressure Volume Loop Would Indicate A
Flat Bottom As Manifested By No Rise In Pressure With The First 200 Ml Of
Delivered Volume. We Call This A "Flat Football". The Solution Is To Increase

,PEEP To A Level That The Pressure Begins To Rise Immediately As Volume Is
Introduced.


Which Of The Following Would Be The Most Effective, Appropriate Method For
Resolving Atelectasis In A Spontaneously Breathing, Post Operative Patient Who Is
Under The Influence Of Sedation And Will Not Respond To Verbal Stimuli?
A. IPPB
B. Sustained Maximal Inhalation (Incentive Spirometer)
C. Deep Breathing Coaching
D. Intubation And Mechanical Ventilation


ANS: A.
A Postoperative Patient Under Sedation, And Possibly In Pain, May Be Tempted To
Breathe Less, Causing Respiratory Acidosis And Atelectasis. To Correct This
Problem, IPPB Therapy Is Most Appropriate. Incentive Spirometry Would Also Help
But The Patient Is Unable To Respond To Verbal Stimuli. This Alone Is An
Indication For IPPB Therapy.


After Performing Minimum Occluding Volume Technique With A 65-Kg (143-Lb)
Patient Who Is Orally Intubated With A 7.0-Mm ET Tube, The Respiratory Therapist
Should NEXT
A. Check ET Tube Cuff Pressure
B. Perform Tracheal Palpation
C. Order A Chest Radiograph
D. Document ET Tube Markings At The Lips


ANS: A.
The ET Tube Cuff Pressure May Be Adjusted Correctly By Several Techniques
Including Minimum Leak Technique (Also Called Minimum Occluding Volume,
Minimal Seal Technique, And The Use Of A Pressure Manometer Called A
Cuffalator. If Minimum Seal Or Minimal Leak Technique Is Used, The Respiratory
Therapist Is Still Required To Monitor The Pressure After The Technique Is
Performed. Although This Is Often Not Done In Real Life, It Is Technically Part Of
The Procedure.

,The Respiratory Therapist Observes An ECG Wave Form On A Patient That Is
Consistent With Atrial Tachycardia. The Patient Is Complaining Of Chest Pain,
Dizziness, And Nausea. The Respiratory Therapist Should Recommend
A. Unsynchronized Defibrillation
B. Atropine Sulfate
C. Epinephrine
D. Cardioversion


ANS: D.
Non-Deadly Arrhythmias, Such As This One, May Be Addressed Through
Cardioversion. Cardioversion Is A Form Of Defibrillation With Low Wattage And
With The Synchronization Set To "Active". This Allows The Shock To Be
Synchronized To The R Wave.


A 38-Year-Old Male Presents In The Emergency Department (ED) Complaining Of
Frequent Vomiting. The Following Laboratory Data Is Available: Arterial Blood
Gases
Ph 7.55 Paco2 42 Torrpao2 85 Torrhco3- 31 Meq/LBE +7 Meq/LFIO2 0.21K+ 3.0
Meq/Lcl- 95 Meq/Lna+ 135 Meq/L
Which Of The Following Should The Respiratory Therapist Recommend?
A. Administer Nacl
B. Administer Nahco3-
C. Administer KCL
D. Administer Volume-Expanding Fluids


ANS: C.
This Patient Has A CO2 Of 42 Mmhg, Which Suggests Adequate Ventilation.
However, The High Ph Is Associated With Alkalosis. Because The CO2 Is Normal,
The Cause Of The Alkalosis Must Be Metabolic In Nature. One Treatment For
Metabolic Alkalosis Is To Administer Potassium Chloride Or Kcl.

, A Patient Is Receiving Volume-Controlled Ventilation Following Bariatric Surgery
For Obesity. Which Of The Following Medications Should The Respiratory Therapist
Recommend To Ensure The Patient's Comfort And Assist In Ventilator Management?
A. Pronestyl
B. Morphine Sulfate
C. Vecuronium Bromide (Norcuron)
D. Mestinon


ANS: B.
Morphine Sulfate Is One Of The Best Medications To Administer To Patients
Receiving Mechanical Ventilatory Support To Help The Patient Rest Pain-Free And
To Generally Sedate And Relax The Patient.


A Patient Has Idiopathic Pneumonia With Consolidation In The Right Lower Lobe.
The Physician Suspects A Bacterial Infection. Which Of The Following Will Provide
Conclusive Data To Rule Out The Physician's Suspicions?
A. WBC
B. Color Of Sputum
C. Sputum Acid-Fast Stain
D. Oral Temperature


ANS: A.
A Bacterial Infection Is Diagnosed Primarily By Examining The White Blood Cell
Count, Also Called The Leukocyte Count. An Elevated Temperature And Yellow
Sputum Indicate The Possibility Of An Infection But Are Not Confirming In Nature.


After Making The Universal Sign Of Choking, A Person Collapses. The Observer
Should FIRST
A. Check For A Pulse
B. Call For Help
C. Perform Abdominal Thrusts
