Which of the following is NOT listed as a part of anesthesia?

• A. Induction
• B. Maintenance
• C. Emergence
• D. Sedation

Answer: (D)

Think of general anesthesia as a staged process: induction is how you start the anesthetic and achieve unconsciousness, maintenance keeps you in that anesthetized state during the procedure, and emergence is the wake-up phase as the anesthesia wears off and recovery begins. Sedation, while related and able to be used for procedures on a lighter scale, describes the depth of a sedative state rather than a phase of the general anesthesia plan itself. It’s a separate category that can range from minimal to deep and may accompany or precede different anesthesia approaches, but it isn’t one of the standard phases of general anesthesia. That’s why sedation isn’t listed as part of anesthesia in this context.
