A nurse at an urgent care clinic is caring for a child who hit her head on the playground at school 30 min ago. Which of the following findings is the nurse's priority?

A. Nasal discharge negative for glucose indicates that there is no cerebrospinal fluid (CSF) leakage, which is a positive sign. While it is important to note, it is not the priority in this situation. B. A negative Babinski reflex is a normal finding in children older than 2 years. It does not indicate an acute issue and is not the priority. C. Asymmetric pupils can be a sign of increased intracranial pressure or a serious brain injury, making this the priority finding. It requires immediate attention to prevent further complications. D. A 2 cm scalp laceration, while needing medical attention, is not life-threatening and is not the highest priority compared to potential brain injury indicated by asymmetric pupils.
