  1. The Larson maneuver (bilateral laryngospasm notch pressure) is used to treat:

    Answer: Laryngospasm by stimulating a cranial nerve reflex to break the glottic closure

    Firm bilateral pressure in the laryngospasm notch (behind the ear lobe, anterior to the mastoid) stimulates a pain response that reflexively relaxes the laryngeal spasm.

  2. Succinylcholine (suxamethonium) is used to break refractory laryngospasm because it is:

    Answer: A depolarizing neuromuscular blocking agent that produces rapid, brief paralysis

    Succinylcholine causes rapid depolarization and complete muscle relaxation within 60 seconds, opening the glottis to allow ventilation and intubation if needed.

  3. What is the recommended treatment for a hypertensive urgency (SBP 180 to 220 mmHg, no target organ damage) discovered before a dental sedation procedure?

    Answer: Postpone elective sedation and refer to physician for blood pressure management

    Hypertensive urgency without target organ damage warrants postponement of elective sedation and medical referral rather than emergent in-office antihypertensive treatment.

  4. A diabetic patient receiving IV sedation becomes diaphoretic with a blood glucose of 48 mg/dL and is conscious. The appropriate immediate action is:

    Answer: Give 15 to 20 g oral glucose (juice, glucose tablets) and recheck glucose in 15 minutes

    For mild hypoglycemia in a conscious patient able to swallow, oral glucose (15-15 rule) is the preferred initial treatment.

  5. Which sign differentiates malignant hyperthermia (MH) from anesthetic overdose as the cause of a sedation complication?

    Answer: Rapid rise in temperature, muscle rigidity, and masseter spasm with metabolic acidosis

    MH is characterized by rising temperature, generalized muscle rigidity, masseter spasm, tachycardia, hypercarbia, and metabolic acidosis - a hypermetabolic crisis, not typical of overdose.

  6. During a dental emergency involving total airway obstruction, if BVM ventilation and repositioning fail, the next definitive airway rescue technique is:

    Answer: Supraglottic airway (e.g., LMA) or endotracheal intubation

    If basic airway maneuvers fail to restore ventilation, a supraglottic airway (LMA) or endotracheal intubation provides a definitive secure airway.
