You should not use metal pushers or sharp implements on clients who have __________?

Using metal pushers or sharp implements on clients who have any chronic disease is not advisable because such conditions can compromise the skin's integrity and overall health. Chronic diseases may lead to issues like reduced circulation, skin fragility, or compromised immune response, which can increase the risk of injury or infection during nail procedures.

For instance, conditions such as diabetes can lead to neuropathy and poor wound healing, making any nicks or cuts from sharp tools potentially serious. Similarly, clients with autoimmune disorders or skin diseases could experience heightened sensitivity or reactions to sharp implements, further complicating their treatment.

The other options, while important considerations in their own right, may not universally contraindicate the use of metal pushers or sharp implements in the same way. Skin irritation could be a cautionary factor but does not inherently signify a compromise in overall health, nor does it apply to all chronic diseases. Overgrown nails can warrant careful attention but are not directly related to overall health in the same capacity as chronic diseases. Edema refers to swelling that could indicate various health problems but is not as broadly applicable as the considerations of chronic diseases in this context.
