Induction: - ideally _____ - give ______ to effect - pre________

• A. IV, slowly, oxygenation
• B. IM, rapidly, preoxygenation
• C. Oral, quickly, ventilation
• D. IV, fast, preoxygenation

Answer: (A)

Induction is typically done with an IV anesthetic that is titrated to effect, after properly preoxygenating the patient. Using an IV route provides rapid and controllable onset, allowing the dose to be adjusted to achieve unconsciousness without overshooting. Giving the drug slowly to effect helps maintain hemodynamic stability, reducing the risk of abrupt hypotension or other instability that can occur with a large bolus. Preoxygenation fills the lungs with oxygen, extending the safe period of apnea during airway management. The prefix pre- combined with oxygenation forms preoxygenation, which is essential before induction. IM or oral routes and rushing to effect are less predictable and can compromise safety.
