A stable 6-day-old infant requires a temperature-controlled environment. Which method is most appropriate?

• A. Oxyhood
• B. Radiant warmer
• C. Isolette
• D. Oxygen tent

Answer: (C)

Maintaining a stable thermal environment is essential for newborn thermoregulation. An isolette provides an enclosed, temperature- and humidity-controlled chamber that preserves a neutral thermal environment, helps prevent hypothermia, and protects the infant from drafts while allowing caregivers to monitor and care for the baby.

The other options are less suited for ongoing temperature control: an oxyhood delivers oxygen and some warmth but is primarily for short-term oxygen therapy and is not a sealed, long-term temperature-maintenance solution; a radiant warmer offers quick, localized warming for procedures or resuscitation but does not provide the stable, enclosed environment needed for several days; an oxygen tent is an open system with less reliable temperature control and stability, making it inferior for sustained temperature management.
