A neonate with cold feet, excessive sleepiness, and sunken fontanelles may be experiencing what condition?

  1. Hyperthermia

  2. Dehydration

  3. Malnutrition

  4. Hypoglycemia

The correct answer is: Dehydration

The symptoms described—cold feet, excessive sleepiness, and sunken fontanelles—are indicative of dehydration in a neonate. Cold extremities can occur due to poor circulation, which may be a result of a reduced blood volume associated with dehydration. Excessive sleepiness suggests decreased activity or responsiveness, which can be a sign of inadequate fluid intake or significant fluid loss. Sunken fontanelles, or the soft spots on a baby's head, are a classic clinical sign of dehydration, as this indicates a loss of the normal intracranial pressure that keeps these areas taut. Together, these signs strongly point towards dehydration as the underlying issue affecting this neonate. Understanding dehydration in neonates is crucial because timely recognition and intervention are essential to prevent complications. Hydration status in infants can change rapidly, and neonates have a higher metabolic rate and fluid turnover than older children or adults, making them more susceptible to dehydration.
