What is the proper response if a patient shows signs of a brain injury?

Monitoring vital signs closely is the correct response if a patient shows signs of a brain injury because it allows for the detection of any changes in the patient's condition that may indicate deterioration. Vital signs, including heart rate, blood pressure, respiratory rate, and consciousness level, provide crucial information about the patient’s status. Changes in these signs can suggest increased intracranial pressure, the need for urgent medical intervention, or other complications associated with brain injuries.

While using a nasopharyngeal airway may be appropriate in certain situations to maintain airway patency, it is not a universal requirement for all brain injury cases. Surgery is typically not an immediate course of action without further evaluation and is usually reserved for situations that are life-threatening or require surgical intervention after assessment by qualified medical personnel. Placing the patient in a sitting position is not generally advised as it may exacerbate certain types of brain injuries by increasing intracranial pressure and impacting blood flow.
