During a newborn's oral examination, which of the following findings would be considered abnormal?

In the context of a newborn's oral examination, an arched palate is considered a normal finding. An arched palate indicates that the hard palate has developed adequately and is functioning as designed. However, options that describe anomalies must reflect a deviation from expected findings.

The presence of an abnormal finding in a newborn's oral cavity would typically relate to potential issues that require further evaluation. In this case, an arched palate does not indicate any problem and instead represents normal anatomical structure. Abnormal findings might include things like a cleft palate, which would be indicated by a lack of proper arching or additional structural concerns.

The findings of the mouth being midline on the face and a strong sucking reflex further indicate normal developmental characteristics in newborns. A palate with no arching could signal a potential issue and would typically be considered abnormal, leading to closer examination and follow-up.

Thus, identifying the arched palate as a normal measurement, while recognizing that alternatives like a flat or non-arched palate would raise concern, clarifies the understanding of expected findings in neonatal assessments.
