  1. Which scenario represents the correct use of flumazenil in the dental office?

    Answer: Reversal of benzodiazepine sedation with respiratory compromise

    Flumazenil is a benzodiazepine antagonist used to reverse excessive CNS and respiratory depression from benzodiazepine sedation.

  2. A patient becomes hypertensive with a blood pressure of 185/110 mmHg mid-procedure. The patient has no symptoms. What is the appropriate action?

    Answer: Discontinue the procedure, allow rest, and recheck BP in 5 minutes

    Asymptomatic hypertension in the dental chair warrants stopping treatment, calming the patient, and rechecking blood pressure before proceeding.

  3. The MOST common cause of medical emergencies in the dental office is:

    Answer: Vasovagal syncope

    Vasovagal syncope is the most frequently encountered medical emergency in dental practice, typically triggered by anxiety, pain, or the sight of blood.

  4. A patient wearing nitroglycerin patches presents for an appointment. The dental team should be aware that combining nitrates with which drug class can cause severe hypotension?

    Answer: Phosphodiesterase-5 inhibitors (e.g., sildenafil)

    Combining nitrates with PDE-5 inhibitors (sildenafil/Viagra) causes profound, potentially fatal hypotension due to synergistic vasodilation.

  5. During a dental emergency involving cardiac arrest, chest compressions should be performed at a depth of:

    Answer: At least 2 inches (5 cm)

    Current AHA guidelines recommend chest compressions of at least 2 inches (5 cm) but not more than 2.4 inches for adults.

  6. A child patient ingests a large dose of acetaminophen from the dental medicine cabinet. The most appropriate immediate action is:

    Answer: Activate Poison Control (1-800-222-1222) and EMS

    Contacting Poison Control and activating EMS ensures expert guidance and rapid transport for acetaminophen overdose management.

  7. Which of the following is the recommended site for IM epinephrine injection during anaphylaxis?

    Answer: Anterolateral thigh (vastus lateralis)

    The anterolateral thigh provides faster and more reliable absorption of epinephrine during anaphylaxis than any other IM site.
