Explanation

A radiant warmer or incubator provides a controlled, thermoneutral environment, which is the most effective method for managing temperature in a sick neonate who cannot self-regulate.
These devices use active heating, often with a servo-control mechanism that adjusts heat output based on the infant's skin temperature to maintain it within a precise, normal range (36.5°C to 37.2°C).
This active intervention is critical for preventing the severe consequences of hypothermia, such as hypoglycemia, metabolic acidosis, and respiratory distress.
Unlike passive measures, incubators and warmers can overcome significant heat loss and provide consistent, reliable warmth required for a compromised infant.

Option A: Placing a newborn near an open window exposes them to drafts, which causes significant heat loss through convection, directly contradicting the goal of preventing hypothermia.
Option B: Bathing causes rapid heat loss through evaporation. Frequent bathing would severely increase the risk of hypothermia in a sick newborn.
Option C: Swaddling with a thin blanket is a passive warming measure. It relies on the baby's ability to generate heat, which the stem explicitly states the 'sick newborn' is unable to do effectively. It is insufficient for active rewarming or maintenance.

Clinical Relevance

Nursing practice connection: Knowing Neonatal thermoregulation and prevention of hypothermia in sick newborns helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Maintaining the 'warm chain' is a series of essential steps to keep a newborn warm from birth. A break in this chain can quickly lead to life-threatening hypothermia.
Hypothermia in a newborn is a medical emergency. It can cause a cascade of problems including hypoglycemia, metabolic acidosis, increased oxygen consumption, respiratory distress, and increased mortality.
Nurses must be able to differentiate between the needs of a healthy term infant and a sick or preterm infant. While skin-to-skin contact is excellent for stable babies, sick infants require the controlled environment of an incubator or warmer.

How to Approach the Question

First, identify the patient's status from the question stem. The key descriptors are 'sick newborn' and 'unable to maintain body temperature'.
This immediately tells you that the baby's own thermoregulatory system is failing and passive measures will not be enough.
Next, evaluate each option in terms of heat gain versus heat loss.
Eliminate options that cause heat loss: 'Placing near open window' (convection) and 'Bathing frequently' (evaporation) are clearly incorrect and harmful.
Compare the remaining two options: 'Swaddling' (passive warming) and 'Radiant warmer/incubator' (active warming).
For a sick infant who cannot generate sufficient heat, an active warming method is required. Therefore, the use of a radiant warmer or incubator is the most effective and appropriate intervention.

Concept Tested & Keywords

Concept Tested: Neonatal thermoregulation and prevention of hypothermia in sick newborns.
Stem keywords: sick newborn, unable to maintain body temperature, prevent hypothermia
Lead-in keywords: most effective
Clinical cues: The phrase 'sick newborn' indicates a compromised state requiring active medical intervention, not just basic comfort measures.
Clinical cues: The phrase 'unable to maintain body temperature' signifies a failure of the neonate's own thermoregulatory mechanisms.
