When obtaining a rectal temperature from an infant, how far should the probe be inserted?

When obtaining a rectal temperature from an infant, it is important to insert the probe the correct distance to ensure an accurate reading and to minimize the risk of injury. The recommended insertion for a rectal temperature in infants is approximately ½ inch. This depth is sufficient to obtain a reliable measurement while also being cautious enough to prevent excessive insertion, which could cause discomfort or injury.

Other options suggest either too little or too much insertion. A 1-inch insertion may pose more risk than what is necessary, while ¾ inch and 2 inches are inappropriate distances that could lead to complications. Proper technique is critical in pediatric care to ensure safety and accuracy.
