Sample item

Why is forced-air warming commonly used during major abdominal surgery?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. To reduce inadvertent hypothermia and its complications

General and neuraxial anesthesia impair thermoregulation, while exposure and cool fluids increase heat loss. Active warming reduces inadvertent perioperative hypothermia, which is associated with coagulopathy, discomfort, and delayed recovery.

Option by option

  • A. To replace antibiotic prophylaxis

    Warming does not substitute for infection prophylaxis.

  • B. To deliberately increase blood loss

    Hypothermia can worsen coagulation and bleeding rather than protect against it.

  • C. To reduce inadvertent hypothermia and its complications (correct)

    Correct. Active warming helps preserve core temperature and reduce hypothermia-related harm.

  • D. To deepen neuromuscular blockade

    Temperature management does not deepen paralysis.
