When a client experiences an adverse reaction during a service, stopping the service immediately and providing assistance is the most appropriate response. This prioritizes the client's health and safety by allowing for an assessment of the reaction and necessary first aid measures.

Continuing the service could exacerbate the situation, potentially leading to further discomfort or harm. Applying soothing lotion and proceeding might not address the underlying cause of the reaction and could also worsen the client's condition. Notifying a co-worker while assuming the service can continue does not focus adequately on the immediate needs of the client, which may lead to neglecting their well-being.

The correct approach ensures that the client is attended to promptly and appropriately, allowing for proper handling of any adverse effects they may be experiencing.
