What are some signs that a client may have a nail infection?

The correct answer pertains to key indicators of a nail infection, which include redness, swelling, pus, and unusual odors. These symptoms typically suggest that an infection may be present. When a client is experiencing these signs, it's essential to recognize that the body is responding to an invasion of pathogens, which can cause inflammation and other noticeable changes. Pus indicates the presence of infection, while unusual odors often arise from bacterial activity.

The other options do not accurately indicate a nail infection. For instance, dry cuticles may point to dehydration or a lack of moisture but are not definitive signs of infection. Regular nail growth is a normal physiological process and doesn't indicate any issues with the nail or surrounding tissue. Discoloration of nail polish can result from a variety of non-infectious causes, such as staining, and does not necessarily imply an infection. Understanding these specific signs is crucial for nail technicians to assess clients effectively and recommend appropriate actions or referrals.
