Compared with axillary measurement, which method is generally more accurate for assessing fever in children?

• A. Rectal
• B. Tympanic
• C. Oral
• D. Axillary

Answer: (A)

Rectal temperature measurement closely reflects the body's core temperature in children, so it is typically the most accurate method for assessing fever. Measuring inside the rectum provides a reading that is less influenced by ambient conditions or external factors, giving a true sense of the child’s fever status. Axillary readings, by contrast, often underestimate fever because they’re more affected by ambient temperature, armpit moisture, and clothing. Tympanic readings can be convenient, but their accuracy varies with how well the probe is placed, ear anatomy, and wax or debris in the ear. Oral temperatures require the child’s cooperation and can be affected by recent meals, fluids, or mouth breathing, making them less reliable in younger children. For precise fever assessment in pediatric patients, the rectal method is generally preferred.
