Sample NBRC TMC practice questions

These sample items mirror the domains in the timed NBRC TMC mock. Correct answers and explanations unlock inside the practice session.

  1. Sample 1

    When titrating O2 in a patient at risk for hypercapnic respiratory failure, best practice is to?

    • A. Always give FiO2 1.0 without monitoring
    • B. Target appropriate SpO2 goals and monitor ventilation/ABG as clinically indicated
    • C. Withhold all oxygen despite SpO2 70%
    • D. Ignore rising PaCO2 and somnolence

  2. Sample 2

    A sudden drop in SpO2 with unilateral absence of breath sounds after central line placement suggests

    • A. Improved lung recruitment
    • B. Normal finding after all line placements
    • C. Need to increase tidal volume blindly without assessment
    • D. Possible pneumothorax—assess and notify the team urgently

  3. Sample 3

    Post-intubation deterioration with asymmetric chest rise after clavicle line placement suggests

    • A. Normal equal ventilation
    • B. Need to add a bite block only
    • C. Immediate oral diet
    • D. Mainstem intubation or pneumothorax—assess, auscultate, adjust tube depth, image/decompress as indicated

  4. Sample 4

    A pulse oximeter probe reading poorly on a cold, vasoconstricted finger may improve by:

    • A. Clamping the probe harder until pain guarantees accuracy
    • B. Trusting a flat SpO2 of 50% without clinical correlation
    • C. Painting nails with opaque polish and ignoring artifacts
    • D. Warming the site or using an alternate site/probe designed for low perfusion

  5. Sample 5

    Foreign-body airway obstruction with severe signs in a conscious adult is treated with:

    • A. Offering water and leaving the patient alone
    • B. Blind finger sweeps in all conscious adults routinely
    • C. Abdominal thrusts (Heimlich) or approved protocol until expulsion/unresponsiveness pathways
    • D. Peak flow measurement first
