QUESTION
Ketamine hydrochloride is a/an?
OPTIONS
(A) Inhalant anaesthesia
(B) Intravenous anaesthesia
(C) Dissociative anaesthesia
(D) Local anaesthesia
ANSWER
(C) Dissociative anaesthesia
EXPLANATION
Ketamine produces dissociative anesthesia by disrupting integrated sensory perception and acting chiefly through NMDA receptor antagonism. It can be administered intravenously but its pharmacologic class is dissociative, not inhalant or local anesthesia; the route in option B is less specific than the correct classification.
