Which condition would prevent a client from receiving a pedicure treatment?

A client presenting with tinea or ringworm, which is a fungal infection, should not receive a pedicure treatment. This condition is contagious and can easily spread from one individual to another, particularly in a salon environment where tools and surfaces come into contact with multiple clients. A nail technician must prioritize the health and safety of all clients by not performing services on infected areas.

While calluses, general foot odor, and fungal nails may be bothersome or require additional attention, they do not pose the same risk of contagion as tinea or ringworm does. Proper treatment and care can often manage calluses and foot odor without concern for spreading infections, and nail technicians can address fungal nails with appropriate precautions while still providing services under certain conditions. However, the presence of tinea or ringworm necessitates avoiding treatment altogether to protect the client and others in the salon.
