The nurse is preparing materials to instruct a pregnant patient about the use of a local anesthetic to block specific nerve pathways. About which type of pain reduction technique will the nurse instruct the patient?
A) General anesthesia
B) Pressure anesthesia
C) Regional anesthesia
D) Pudendal nerve block
C
Feedback:
Regional anesthesia is the injection of a local anesthetic to block specific nerve pathways. This achieves pain relief by blocking sodium and potassium transport in the nerve membrane so the nerve is unable to conduct sensations. General anesthesia is rarely used and is not referred to as being general anesthesia. Pressure anesthesia results from the fetal head pressing against the stretched perineum. A pudendal nerve block is the injection of a local anesthetic through the vagina to anesthetize the pudendal nerve.
