If a person has been struck on the head and shows confusion and a headache, what is the most appropriate action to take?

The most appropriate action when a person exhibits confusion and a headache following a head injury is to recommend that they be evaluated by a healthcare provider. This is crucial because confusion and headache can be indicative of a serious condition, such as a concussion or other traumatic brain injury. A healthcare provider has the expertise to assess the individual’s symptoms properly, conduct any necessary imaging studies, and determine the appropriate care based on medical standards and protocols.

Prompt evaluation by a healthcare professional is necessary to prevent complications that may arise from undiagnosed injuries. While providing water and snacks might help in general situations of minor fatigue or dehydration, it's not suitable here due to the potential for serious consequences from a head injury. Similarly, sending someone back to work or delaying action until they feel better could lead to further injury or deterioration of their condition. Therefore, an immediate referral to a healthcare provider ensures safety and proper management of the injury.
