Which action should NOT be performed with a curette?

Using a curette is a delicate procedure that requires an understanding of its appropriate applications and limitations. The correct choice highlights that a curette should not be used to dig into the soft living tissues along the nail fold. This is because the soft tissue around the nails is sensitive and can easily be damaged. Using a curette in this manner poses a risk of injury, causing pain, and potentially leading to infection or other complications.

Curettes are designed to clean and remove debris from areas like the nail folds and under the nail, as well as to assist in pushing back cuticles gently. These actions are appropriate applications of the tool, as they involve working on non-living tissue and surfaces that can tolerate this type of manipulation. To maintain hygienic practices and prevent harm to the client, the curette should always be used with care and proper technique, strictly avoiding any aggressive actions against living tissues.
