Question

When using a rectal thermometer, how far should it be inserted into the rectum for an accurate reading?

a) 0.5 inches
b) 1 inch
c) 1.5 inches
d) 2 inches

Answer 1

A rectal thermometer should be inserted about 0.5 to 1 inch into the rectum for infants, and up to 1 inch for older children and adults for an accurate temperature reading.

Correct option is B

Step-by-step explanation:

When using a rectal thermometer for accurate temperature readings, it should generally be inserted into the rectum about 0.5 to 1 inch (1.25 to 2.5 cm) for infants and up to 1 inch (2.5 cm) for older children and adults. Gentle and secure insertion is essential to avoid causing discomfort. Ensuring accurate placement is crucial for reliable temperature measurements, particularly in clinical settings or when monitoring for fever at home.

This method is often preferred for infants and young children, as rectal temperatures closely reflect core body temperature. Following proper guidelines for insertion depth enhances the precision of temperature assessments, contributing to effective healthcare management and appropriate interventions when necessary.
