The most accurate reading for a temperature is done:

  • A. Orally
  • B. Aurally through a clean canal
  • C. Rectally
  • D. Axially
Correct Answer: B

Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading.

Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.
