The patient is scheduled for a surgical procedure. The nurse plans to teach the patient about anesthesia. Which statement would be included in the best plan of the nurse?
1. "An inhaled agent needs to be followed by an intravenous (IV) agent if it is ineffective."
2. "An inhaled agent is used to induce sleep, followed by an intravenous (IV) agent for relaxation."
3. "An intravenous (IV) agent to induce sleep is usually all that is required."
4. "An intravenous (IV) agent will be used first to induce sleep; then, an inhaled agent will be used."
Correct Answer: 4
Rationale: Intravenous agents are usually administered first because they act within a few seconds. After the patient loses consciousness, inhaled agents are used to maintain the anesthesia. Patients require more anesthesia than just intravenous (IV) anesthesia. An intravenous (IV) agent, not an inhaled agent, is used to induce sleep. Inhaled agents are given after intravenous (IV) agents to maintain anesthesia, not if the intravenous (IV) agent is ineffective.
