Which combination represents the three parts of anesthesia?

• A. Induction, Maintenance, Emergence
• B. Induction, Emergence, Recovery
• C. Onset, Duration, Recovery
• D. Sedation, Anxiolysis, Analgesia

Answer: (A)

The concept being tested is the three phases of anesthesia: induction, maintenance, and emergence. Induction is the transition from waking to an anesthetized state, typically achieved with medications given to render the patient unconscious and insensate to pain. Maintenance is keeping the patient in that controlled, anesthetized condition throughout the surgery with ongoing administration of anesthetic agents and continuous monitoring. Emergence is the process of waking up and returning to spontaneous breathing and consciousness as the drugs wear off or are stopped, followed by recovery in the post-anesthesia period. Other options don’t fit as cleanly because onset/duration/recovery describe timing of effects or general recovery, not the distinct phases of the anesthetic plan. Sedation, anxiolysis, and analgesia refer to levels of calm, fear reduction, and pain control, which are components of perioperative care but do not map to the three standard phases of anesthesia.
