Final answer:
C-Spine precautions should be taken for a patient in this scenario, even if the patient claims to be uninjured and not under the influence of alcohol.
Step-by-step explanation:
C-Spine precautions should be taken for a patient in this scenario. The patient is showing signs of potential head and neck injury, such as confusion and the inability to remember certain details. Even if the patient claims to be uninjured, it is important to err on the side of caution and protect the cervical spine. This can be done by placing the patient on a backboard and applying a cervical collar. The patient should not be assumed to be under the influence of alcohol or in police custody, as these factors do not negate the need for C-Spine precautions.
