Anaesthesia · Monitoring: core temperature

Sample item

Which site best reflects core temperature during general anaesthesia?

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

The answer and the reasoning

D. Lower oesophagus or nasopharynx

Distal oesophageal and nasopharyngeal probes lie close to the heart and the hypothalamus, and follow core changes quickly. Axillary and skin readings lag behind.

Option by option

  • A. Skin of the forehead

    Skin temperature varies with perfusion.

  • B. Axilla

    The axilla underestimates core temperature.

  • C. Great toe

    Peripheral sites lag behind core changes.

  • D. Lower oesophagus or nasopharynx (correct)

    Correct. These sites reflect core temperature.
