What treatment is recommended for hypothermia in newborns?

The correct treatment for hypothermia in newborns involves active rewarming methods rather than the use of medications such as diazepam, which is primarily a sedative and anticonvulsant. In this context, the most appropriate measure is to provide controlled warming strategies, including skin-to-skin contact, warm blankets, or an incubator to raise the newborn's body temperature safely and effectively.

Lactated Ringer's solution, while useful for fluid resuscitation in various clinical scenarios, is not directly indicated for treating hypothermia. Similarly, phenobarbital is used in the management of seizures and not as a treatment for low body temperature. Acetaminophen is an analgesic and antipyretic medication, which does not address the underlying issue of hypothermia and could potentially be harmful if used to artificially raise body temperature.

Since the recommended treatment for hypothermia in newborns centers around methods of rewarming, it is essential to focus on those appropriate techniques rather than medications that do not serve that purpose.
