Which stage involves the patient being put to sleep and may involve securing the airway and administering drugs to help the patient lose consciousness quickly and smoothly?

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

Answer: (A)

Induction is the phase where anesthesia starts. It involves taking the patient from waking to unconscious, often with an IV induction agent such as propofol that acts rapidly to render the patient asleep. Airway management is typically addressed during this phase, with securing the airway (for example, endotracheal intubation or a supraglottic airway) to protect ventilation and enable controlled breathing. Drugs given at this time are chosen to produce a quick, smooth loss of consciousness and amnesia, often alongside analgesics and sometimes a muscle relaxant to facilitate airway instrumentation.

Maintenance follows to keep the patient asleep and stable during the procedure, emergence is the process of waking up as the anesthetic effects wear off, and recovery refers to the post-anesthesia recovery period after leaving the operating room.
