What should be done if a client shows signs of an allergic reaction?

In the event that a client exhibits signs of an allergic reaction, it is critical to prioritize their health and safety. Stopping the service immediately and seeking medical assistance is the appropriate course of action. This ensures that the client's needs are addressed promptly and that they receive the necessary medical evaluation and treatment if required. Allergic reactions can escalate quickly, potentially leading to severe consequences such as anaphylaxis, so taking immediate action can be life-saving.

Continuing the service disregards the client's well-being and could worsen their condition. Documenting the reaction is important for record-keeping but comes after ensuring the client receives appropriate care. Administering an over-the-counter remedy without professional guidance could also pose risks, especially if the client has not been evaluated by a healthcare provider. Therefore, stopping the service and seeking medical assistance is the most responsible response.
