What is the most accurate way to get a temperature on an infant?

Rectal Skin Oral Axillary

Correct Answer:

Skin

Explanation:

Infants need a temperature reading that best reflects core body temperature. Rectal thermometry provides the closest estimate of core temperature in this age group because the rectal area mirrors internal temperature more reliably than surface measurements, which are easily influenced by ambient conditions, movement, or recent feeding. Use a lubricated digital thermometer and insert just a small amount into the rectum with care to avoid injury, following safety guidelines. Axillary temperatures can be affected by room temperature and perspiration, making them less reliable for diagnosing fever in infants. Oral temperatures aren’t appropriate for infants due to cooperation and accuracy issues, and skin temperatures are too variable to reflect true core temperature.
