C
Feedback:
Stage 3 is surgical anesthesia, which involves relaxation of skeletal muscles and return of regular respirations. During this stage, eye reflexes and pupil dilation are progressively lost. Surgery can be safely performed in this stage. Stage 1 refers to the loss of pain sensation; stage 2 involves a period of excitement with sympathetic stimulation (e.g., tachycardia, increased respirations, blood pressure changes); and stage 4 involves deep central nervous system depression with loss of respiratory and vasomotor center stimuli. Death can occur rapidly at this stage if adequate support is not supplied.
