A 35-year-old client is admitted for elective tubal ligation. During the preoperative teaching, the client states, 'The anesthesiologist said she was going to give me balanced anesthesia. What exactly is that?' The best explanation by the nurse is that balanced anesthesia:
- A. is a type of regional anesthesia.
- B. uses equal amounts of inhalation agents and liquid agents.
- C. does not depress the central nervous system.
- D. is a combination of several anesthetic agents or drugs, which produce a smooth induction with minimal complications.
Correct Answer: D
Rationale: A regional anesthesia does not produce loss of consciousness and is indicated for excision of moles, cysts, and endoscopic surgeries. Varying amounts of anesthetic agents are used when employing balanced anesthesia. The amounts used depend on the age, weight, condition of the client and the surgical procedure.
