Which of the following is NOT a method to prevent heat loss in infants?

Placing an infant on a cold surface is indeed not a method for preventing heat loss. In fact, it can lead to increased heat loss in infants, who are particularly vulnerable to hypothermia due to their larger surface area relative to their body mass. Cold surfaces can draw body heat away from an infant, making them much colder and increasing the risk of adverse health effects.

In contrast, methods such as wrapping an infant in a blanket, using a humidifier, and keeping them in a warm room are effective strategies for maintaining their body temperature. Wrapping in a blanket creates insulation, helping to trap warmth. A humidifier can add moisture to the air, which can help maintain body temperature and prevent skin from drying out, while keeping the infant in a warm room ensures that their environment promotes heat retention. These methods effectively combat heat loss and are essential for keeping infants safe and comfortable.
