In the context of radiation heat loss, which is an example of improper positioning of the infant?

The scenario that illustrates improper positioning related to radiation heat loss is one where the infant's bed is situated near a cold window. This specific placement creates a significant temperature gradient, as the cold surface of the window can lead to increased heat loss from the infant's body to the surrounding environment.

Radiation heat loss occurs when the infant's warm body radiates heat to cooler surfaces nearby, and having a cold window adjacent to the infant increases this heat loss, potentially leading to hypothermia. Positioning infants in such environments is particularly critical to avoid, especially in a neonatal intensive care setting where maintaining a stable body temperature is essential for health and development.

In contrast, placing an infant in an incubator or on warm sheets, or ensuring they wear a hat, are measures generally taken to trap heat and promote the infant's thermal stability, thus minimizing the risk of heat loss.
