A Preoperative Patient in the Holding Area Asks the Nurse

A preoperative patient in the holding area asks the nurse, "Will the doctor put me to sleep with a mask over my face?" The most appropriate response by the nurse is,

A) "A drug will be injected through your IV line, which will cause you to go to sleep almost immediately."
B) "Only your surgeon can tell you for sure what method of anesthesia will be used. Should I ask your surgeon?"
C) "Masks are not used anymore for anesthesia. A tube will be inserted into your throat to deliver a gas that will put you to sleep."
D) "General anesthesia is now given by injecting medication into your veins, so you will not need a mask over your face.
