Explanation

Drying the baby thoroughly immediately after birth.
This is the first and most crucial step to prevent hypothermia in a newborn.
Newborns are born wet with amniotic fluid, and the evaporation of this fluid from the skin is the primary and most rapid source of heat loss immediately after delivery.
Prompt and thorough drying, including the head, minimizes evaporative heat loss.
This action is the second step in the 'Warm Chain,' a sequence of procedures designed to prevent neonatal hypothermia, with the first step being a warm delivery room.

Option B: This action is incorrect because it unnecessarily delays drying. The most significant heat loss occurs in the first few minutes after birth, and waiting until the cord is cut exposes the newborn to a prolonged period of rapid cooling.
Option C: Covering a wet baby is counterproductive. The cloth will quickly become wet, and heat will be lost from the baby's body through evaporation from the wet cloth and conduction to the cold, damp surface.
Option D: Similar to the previous option, covering a wet baby, even with a warmed blanket, is incorrect. The baby must be dried first to prevent evaporative heat loss. Placing a warm blanket on a wet baby will lead to the blanket becoming damp and cold, increasing heat loss.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Newborn Thermal Protection and the Warm Chain as background academic context rather than a clinical decision trigger.
Preventing hypothermia is a critical nursing responsibility in the delivery room. A low body temperature (hypothermia) can lead to hypoglycemia, respiratory distress, and metabolic acidosis in a newborn.
Nurses must act quickly, drying the infant on the mother's abdomen while performing initial assessments, promoting skin-to-skin contact, and initiating breastfeeding.
What if the baby requires immediate resuscitation? Even in this emergency, thermal protection is vital. Resuscitation should be performed under a radiant warmer to provide heat while life-saving measures are underway. The baby should still be dried quickly to minimize heat loss.

How to Approach the Question

First, identify the core of the question: it asks for the 'first step' in a specific process (thermal protection for a newborn).
Analyze the options by considering the physics of heat loss in a newborn. A baby is born wet, so evaporation is the most immediate threat.
Evaluate each option based on this principle. Does the action prevent evaporative heat loss?
Option A (Drying) directly addresses evaporation. Options C and D (Covering) do not; they are subsequent steps.
Option B (Drying after cord cutting) introduces a delay. The 'first step' should be the most immediate action.
Conclude that immediate drying is the logical and evidence-based first step to counteract the most significant initial heat loss mechanism.
