What is the appropriate action if a client has a broken nail?

Using a nail glue or wrap to support a broken nail is the most appropriate action because it provides immediate reinforcement and helps prevent further damage. When a nail is broken, the structural integrity is compromised, and applying a nail glue or wrap can stabilize the area, allowing the client to continue with their daily activities without worsening the injury. This method is particularly effective as it can protect the nail from external elements that might aggravate the break, such as water and dirt.

Additionally, this option is proactive and demonstrates care for the client's well-being and appearance. It not only addresses the issue at hand but also offers a temporary solution until the nail can grow out or be professionally attended to in the future. This method encourages clients to maintain their nails’ health and aesthetic appeal by treating issues as they arise in a professional manner.
