Which of the following actions is a proper response if a person appears to be infected?

When a person appears to be infected, consulting a healthcare provider is the most appropriate response. This action is essential because healthcare providers are trained to assess illnesses and determine the necessary treatment based on a professional evaluation of the patient's symptoms. An infection may require medical intervention, such as prescription medications or specific treatments, which only a qualified healthcare professional can provide.

Providing additional fluids may be helpful if the person is dehydrated, but it does not address the underlying infection itself. Ignoring symptoms can lead to worsening of the condition, as infections can progress quickly if not treated properly. Offering solid food may also not be advisable, especially if the person is experiencing symptoms like nausea, vomiting, or lack of appetite, which could complicate their recovery. Therefore, seeking professional medical advice is the most effective and responsible action to ensure the person receives the appropriate care for their infection.
