Which of the following is NOT a normal finding when examining a newborn's oral cavity?

The choice identifying "palate arched" as not a normal finding requires consideration of typical anatomical structures present in a newborn's oral cavity. An intact palate is essential for effective feeding and proper development, and an arched palate can be a common variant observed in many healthy newborns.

In clinical practice, a normal roof of the mouth can appear slightly arched, especially in newborns. Therefore, stating that an arched palate is not a normal finding may not align with prenatal anatomy and physiology concerning the developing infant. When examining newborns, it's important that health professionals understand the nuances of normal anatomy to distinguish between typical variations and potential concerns.

The other options reflect standard observations during newborn examinations, such as an intact palate, a midline mouth for proper symmetry and feeding abilities, and a present sucking reflex, which are crucial indicators of healthy oral and feeding function. Accordingly, recognizing these normal findings emphasizes the importance of functional oral capabilities and anatomical integrity in newborns.
