The emergency room nurse is caring for an adolescent who briefly lost consciousness following a collision with another player on the soccer field. Which sign is concerning? Select all that apply.

A. Patient's pupillary reaction is sluggish: A delayed or unequal pupillary response to light suggests increasing intracranial pressure or damage to the cranial nerves. This is a critical indicator of potential cerebral edema or intracranial hemorrhage following a head injury. Normal pupils should be briskly reactive to light (PERRLA). B. Patient asks "Where am I?": Disorientation to place or time is a hallmark of a concussion or more severe traumatic brain injury. It indicates an impairment of cognitive processing and memory, which are vital parameters in neurological monitoring. Confusion following a loss of consciousness necessitates a higher level of clinical surveillance. C. Patient successfully performs the finger-nose-finger test: This result indicates intact cerebellar function and good coordination, which is a reassuring finding during a neurological exam. Successful completion of this test suggests that the motor pathways and cerebellum are currently functioning normally. It is not a concerning sign in the context of head trauma. D. Patient states "At least we won the game!": This statement demonstrates that the patient has retained recent memory and is capable of forming coherent sentences. It shows an awareness of the event's context and suggests that long-term and immediate recall may be intact. This is a positive sign of cognitive orientation. E. Patient has a positive Romberg test: A positive result, indicated by a loss of balance when the eyes are closed, suggests vestibular or proprioceptive dysfunction. This finding is highly concerning after a head collision, as it may indicate a concussion or injury to the equilibrium centers. It highlights a significant deficit in neurological stability.
