What position should a client be in to obtain a rectal temperature?

To obtain a rectal temperature, the ideal positions are side-lying or prone. These positions provide the best access for safely and comfortably inserting the thermometer. In the side-lying position, the child can be positioned on their left side, which is often preferable as it allows for better visualization and ease of access to the rectal area.

The prone position can also be used, particularly in older children or when a caregiver is holding the child, but it may be less common. The side-lying option is generally recommended for infants and toddlers because it enhances comfort and safety during this procedure.

In contrast, the supine position places the child on their back, potentially making it more difficult to adequately access the rectum without discomfort, while the sitting or standing positions are inappropriate and unsafe for this method of temperature measurement. Therefore, the choice of side-lying or prone positions aligns with best practices in pediatric care for rectal temperature measurement.
