A client has onychophagy and wants a pink and white overlay. How should the form fit?

When addressing onychophagy, which is the habit of biting one's nails, it is essential to provide a nail enhancement that fits securely and supports the nail bed while it grows back. A snug fit under the hyponychium—located at the end of the nail where it meets the fingertip—is crucial for ensuring that the overlay stays in place and provides structural integrity. This snugness helps prevent lifting and allows for a better bond with the natural nail.

Additionally, achieving a tight fit under the hyponychium can help protect the sensitive areas of the nail that may have been damaged due to biting, promoting healthier nail growth and reducing the likelihood of future nail trauma. Ensuring that the overlay doesn't leave loose spots helps maintain the overall aesthetics of the nail and can enhance the client’s confidence as their nails recover from onychophagy.

Other options imply varying degrees of looseness or inappropriate fitting strategies that may not support the structure or health of the nails effectively, which is why they wouldn't be suitable for this specific situation.
