In a newborn diagnosed with hydrocephalus, which of the following physical findings should the nurse anticipate?

In a newborn diagnosed with hydrocephalus, one of the key physical findings to anticipate is dilated scalp veins. This occurs due to increased intracranial pressure, which can lead to the distension of veins on the scalp as the body attempts to accommodate and manage the excess cerebrospinal fluid within the cranial cavity. The pressure buildup influenced by hydrocephalus results in abnormal head growth and can impact blood flow in the area, hence the distension of the scalp veins.

Dilated scalp veins can also be seen in conjunction with an enlarged head circumference and a bulging fontanelle, which are hallmark signs of hydrocephalus. This observation is an important clinical indicator that aids healthcare providers in identifying and managing the condition effectively. In contrast, other physical findings such as low birth weight, excessive crying, and hypertonic muscle tone may not specifically correlate with hydrocephalus in the same direct manner as dilated scalp veins do.
