Which finding would suggest that a newborn may require further assessment after a circumcision?

A fever greater than 100.4°F in a newborn after circumcision is a significant finding that warrants further assessment. Elevated temperatures can indicate infection or other complications following the procedure. After circumcision, it is essential for healthcare providers to monitor the newborn for any signs of abnormal responses, and a fever is one of the primary indicators that something may not be right.

Fever can suggest several issues, including possible infection of the surgical site, which can lead to more serious health concerns if left unaddressed. Therefore, a temperature above the normal range is a clear signal for further evaluation to ensure the safety and well-being of the newborn post-procedure.

In contrast, changes such as decreased appetite, a furrowed brow, or a calm demeanor might not necessarily indicate an immediate complication and could be part of the normal healing or adjustment process for a newborn after circumcision. These findings alone do not typically warrant the same level of concern as a high fever does.
