Question 1

A patient under general anesthesia with succinylcholine and a volatile anesthetic develops sudden tachycardia, masseter muscle rigidity, and a sharp increase in end-tidal CO2. What is the perioperative nurse's priority action?

Apply cooling blankets and prepare chilled IV fluids. Notify the anesthesia professional and prepare to stop the triggering agents. Draw blood for an arterial blood gas (ABG) and electrolyte panel. Prepare for immediate administration of intravenous dantrolene.

Correct Answer:

Notify the anesthesia professional and prepare to stop the triggering agents.

Question 2

Which of the following best describes the emergence phase of general anesthesia?

The period when anesthetic agents are discontinued and the patient begins to awaken, continuing until airway reflexes return. The period from the administration of induction agents to the loss of consciousness. The period starting from when the patient begins to awaken until they are safely discharged from the post-anesthesia care unit (PACU). The period from the surgical incision until near the completion of the procedure.

Question 3

An anesthesia professional must be present and prepared to convert to general anesthesia if needed.
