A client admitted for an appendectomy receives methohexital as a general anesthetic. Which of the following would most likely occur as a result of this medication?
- A. Skeletal muscle relaxation
- B. Profound analgesia
- C. CNS depression
- D. Neuroleptanalgesia
Correct Answer: C
Rationale: Methohexital is an ultrashort-acting barbiturate that depresses the CNS to produce hypnosis and anesthesia, but it does not produce analgesia. Skeletal muscle relaxation is caused by skeletal muscle relaxants, halothane, and enflurane. An anesthetic state characterized by profound analgesia is produced by ketamine, which is a rapid-acting general anesthetic. Neuroleptanalgesia is caused by a combination of fentanyl and droperidol.
