Normal finding in a newborn ?
**Core Concept**
In newborns, a normal finding refers to a physiological characteristic or anatomical structure that is present and considered typical for the age group. This can include various aspects such as physical examination findings, laboratory results, or imaging features.
**Why the Correct Answer is Right**
The correct answer is related to the normal anatomical structure of a newborn's skull. Specifically, the anterior fontanelle, also known as the soft spot, is a normal finding in newborns. It is a diamond-shaped area on the top of the infant's skull where the bones have not yet fused together. This allows for growth and flexibility of the skull as the baby's brain develops.
**Why Each Wrong Option is Incorrect**
**Option A:** This option might refer to a congenital anomaly or an abnormal finding, which is not a normal finding in a newborn.
**Option B:** This option might refer to a condition that is not typically present at birth, such as a fracture or a degenerative disease.
**Option C:** This option might refer to a condition that is not a normal anatomical structure, such as an abnormality in the shape or size of the skull.
**Clinical Pearl / High-Yield Fact**
The anterior fontanelle typically closes between 12 to 18 months of age, and its closure is an important milestone in the development of a child's skull.
**Correct Answer:** C. Bony sutures are not yet closed.
