Which of the following is defined as a state of unconsciousness in which there is loss of sensation throughout the body?

• A. Local anesthesia
• B. General anesthesia
• C. Topical anesthesia
• D. Ophthalmic anesthesia

Answer: (B)

General anesthesia is a state of unconsciousness in which the patient has no awareness and there is loss of sensation throughout the body. It achieves overall insensibility by depressing the central nervous system, allowing surgery with analgesia, amnesia, and muscle relaxation. Because it affects the entire body, it requires airway management and continuous monitoring of breathing and circulation. Local anesthesia numbs only a small, specific area; topical anesthesia affects surface tissues; ophthalmic anesthesia is limited to the eye area. So, the description fits general anesthesia, which produces unconsciousness and widespread loss of sensation.
