What action should be taken if a client exhibits signs of infection?

The most appropriate action when a client shows signs of infection is to advise them to see a physician. This is crucial as infections can pose serious health risks and may require medical treatment that exceeds the scope of practice for manicurists. By referring the client to a healthcare professional, you prioritize their health and safety, ensuring they receive the necessary care for their condition.

Continuing the service, as suggested by another option, could exacerbate the infection, leading to further complications and also poses a risk of spreading pathogens to other clients. Ignoring the signs dismisses a potential health issue that needs attention and can damage the trust between you and your client, as well as violate health and safety regulations. Documenting the incident, while important for your records, is not a proactive response and does not address the immediate need for medical care that the client may require. Therefore, advising the client to seek medical attention is the most responsible course of action.
