Chapter 11 Questions
Question 1 of 5
During a fishing trip, a patient pierced his finger with a large fishhook. He is now in the emergency department to have it removed. The nurse anticipates that which type of anesthesia will be used for this procedure?
Correct Answer: D
Rationale: Infiltration anesthesia with lidocaine is appropriate for minor surgical procedures like fishhook removal, as it involves injecting anesthetic around the wound to block local nerves. No anesthesia is impractical due to pain, and topical agents like benzocaine or EMLA are less effective for deeper wounds.
Question 2 of 5
While monitoring a patient who had surgery under general anesthesia 1 hour ago, the nurse notes a sudden elevation in body temperature. This finding may be an indication of which problem?
Correct Answer: D
Rationale: Malignant hyperthermia is a life-threatening condition associated with general anesthesia, characterized by a sudden rise in body temperature. Tachyphylaxis refers to reduced drug response, postoperative infection develops more slowly, and malignant hypertension primarily involves blood pressure elevation.
Question 3 of 5
When assessing patients in the preoperative area, the nurse knows that which patient is at a higher risk for an altered response to anesthesia?
Correct Answer: D
Rationale: Elderly patients, like the 82-year-old, are at higher risk for altered anesthesia responses due to age-related declines in hepatic, cardiac, respiratory, and renal function. Younger patients or those with no significant comorbidities are less likely to have altered responses.
Question 4 of 5
The nurse is caring for a patient who is on a ventilator for respiratory arrest. Which parenteral anesthetic is also used for sedation during mechanical ventilation in ICU settings?
Correct Answer: C
Rationale: Propofol is used for both general anesthesia and sedation in ICU settings for mechanically ventilated patients due to its rapid onset and short duration. Ketamine is used for anesthesia and moderate sedation, midazolam for moderate sedation, and sevoflurane is an inhaled anesthetic not typically used for ICU sedation.
Question 5 of 5
When administering a neuromuscular blocking drug, the nurse needs to remember which principle?
Correct Answer: D
Rationale: Neuromuscular blocking drugs paralyze all skeletal muscles, including respiratory muscles, requiring mechanical ventilation. They do not provide sedation or pain relief and are used with, not instead of, general anesthesia.
