Which implement should not be used to push back the eponychium?

The appropriate implement for pushing back the eponychium, which is the living tissue at the base of the nail, should be designed for that particular purpose to avoid injury. The metal pusher is specifically created for this task; however, it can be misused especially if not handled correctly, leading to damage to the nail matrix or surrounding skin.

Although the metal pusher is a common tool among professionals for gently pushing back cuticles, it is vital to apply it properly and with care. Using excessive force or an improper angle can potentially harm the delicate eponychium and the skin surrounding it. A proper technique is always emphasized in training to ensure safe practices.

In contrast, nail nippers, tweezers, or disinfection containers are not intended for this specific purpose. Nail nippers are designed for trimming excess nail material, while tweezers are generally used for picking up small items, not for manipulating the eponychium. A disinfection container serves to sterilize tools rather than interact with nail anatomy. Thus, while a metal pusher can be used for eponychium care, caution is key due to the potential risks.
