Final answer:
An anatomically shaped mask should be fitted with the rounded end covering the newborn's nose, considering the occipital fontanel and other physiological features of neonates.
Step-by-step explanation:
An anatomically shaped mask should be positioned with the rounded end over the newborn's nose. This design ensures that the mask fits properly over the face, taking into account the occipital fontanel located at the back of the newborn's head and other unique physiological features of a newborn, such as the openness of the fontanels and the large relative size of the head compared to the body. It's crucial for healthcare professionals to be aware of these characteristics when providing care to ensure the safety and comfort of the neonate.
