Wisconsin CNA State Exam Vocabulary Practice

The correct answer is toenails, which specifically refers to the hard protective coverings at the tips of each toe. Toenails are composed of a tough protein called keratin, similar to fingernails, and serve several functions, such as protecting the sensitive tissues of the toes and enhancing the ability to grip surfaces.

The other possibilities, such as trachea, which is the tube that connects the throat to the lungs, and transfer belt, which is a device used to assist with the movement of patients, do not relate to the nails on the toes. The term "special term" does not provide any specific medical terminology relevant to the question. Therefore, toenails are the precise and commonly recognized term for the nails found at the tips of the toes.
