Final answer:
The professional should not perform the requested nail service if it could harm the client's nails, but instead offers an alternative service, devises a plan of action to improve nail health, and suggests beneficial products.
Step-by-step explanation:
When a professional encounters nails that are not in a condition to support the requested service, such as a manicure or pedicure, it is essential to prioritize the client’s nail health over the aesthetic desire. Performing the requested service on damaged or unhealthy nails can further weaken them and lead to more severe nail issues.
Therefore, the correct course of action includes discussing an alternative service that can be safely performed, creating a plan of action to help treat and improve the condition of the nails, and recommending products to improve nail health. An approach that does NOT constitute a recommended solution is to carry out the originally requested service when it is evident that the nails could be harmed.
