Final answer:
A bulb syringe is kept available when changing a newborn's diaper to clear any mucus or milk from the infant's mouth or nose after feeding, as they are prone to regurgitation and have immature reflexes, potentially leading to choking or aspiration.
Step-by-step explanation:
A bulb syringe is often kept available when changing a newborn's diaper to clear any mucus or milk that may have regurgitated into the infant's mouth or nose. Newborns have immature reflexes and may not clear these substances effectively on their own, which can pose a risk of choking or aspiration. This is particularly important shortly after feeding, when the likelihood of regurgitation is higher. In addition, due to their homeostatic imbalances and the fact that their kidneys are not yet fully mature, newborns are at a higher risk of dehydration. The use of breast milk or formula helps maintain homeostasis in the newborn, providing adequate fluids to compensate for their dilute urine and ensuring proper hydration.
The Apgar score is a method used to assess a newborn's wellbeing immediately after birth, taking into account factors such as heart rate, respiration, and other vital signs. This score assists healthcare providers in determining if medical interventions, like the bulb syringe, are necessary to support the infant's transition to life outside the womb.
