High-Risk Pregnancy and Newborn Adaptation · NCLEX Exam

Why is thermoregulation critical in the adaptation of high-risk newborns?

  1. Excess subcutaneous fat insulating preterm infants
  2. Cold stress raises oxygen use, causing hypoxia and acidosis
  3. Thermoregulation becomes relevant only after discharge
  4. Term infants reliably self-maintain a normal temperature
Show answer and explanation

Correct answer: Cold stress raises oxygen use, causing hypoxia and acidosis

Cold stress can lead to increased oxygen demand, hypoxia, and metabolic acidosis, especially in high-risk or premature infants.
