Final answer:
The mask correctly placed on a newborn's face must be designed for neonatal use, fitting snugly over the nose and mouth without obstructing the eyes or pressing on soft spots such as the occipital fontanel.
Step-by-step explanation:
When placing a mask on a newborn's face, care must be taken to ensure no obstruction occurs to the newborn's breathing. Considering the neonate's anatomy, such as the occipital fontanel, it's important to avoid applying pressure to any soft spots on the head. The mask must be sized and shaped appropriately for a newborn's small face, respecting the unique proportions and sensitive areas like the fontanels and the still-coating vernix.
A mask for clinical use on a newborn's face, such as for administering oxygen or protection, must be specifically designed for newborns. It should fit snugly but comfortably over the nose and mouth without pressing on the infant's eyes or obstructing their vision. Since newborns prefer to look at faces, particularly their mother's face, the mask should not hinder this important aspect of bonding and development.
