What is an important sign of a serious infection in clients?

Redness or swelling around the nails is a critical indicator of a serious infection in clients. This inflammation often suggests that there is an underlying issue such as an infection that could be caused by bacteria or fungi. Such symptoms can arise from various factors, including improper nail care, injuries, or pre-existing conditions that compromise skin health.

Infections may be accompanied by other symptoms, but redness and swelling are particularly significant because they indicate that the body is sending immune response cells to fight off potential pathogens. Recognizing these signs early can help prevent the infection from worsening and can lead to timely intervention, which is essential in providing safe and effective nail care.

The other options do not typically indicate a serious infection; dry cuticles, for example, may point to dehydration or lack of moisture but not an infection. Changes in nail color due to polish are cosmetic and may concern aesthetics rather than health. Occasional skin peeling can result from dryness or irritation but does not necessarily signal an infection. Understanding the specific and serious signs of infections can greatly enhance a nail technician's ability to protect the health and well-being of their clients.
