Which of the patient's senses is last lost before unconsciousness from anesthesia is assumed?
a. Taste
b. Sight
c. Hearing
d. Touch
ANS: C
Hearing is the last sense lost when becoming unconscious. It is not known at precisely what moment a person can no longer hear and interpret what is said, but it is known that patients remain aware of their environment much longer than their seemingly unconscious state would indicate. Therefore, team members should think before speaking and should not converse near the patient while excluding him or her from the conversation. Sedation does not imply exclusion. The patient may be aware of conversation, even if he or she appears to be asleep! Out of the patient's hearing, conversation should pertain only to the work at hand.
