What is a sign of infection that an HHA should look for when caring for a client?

Fever is a classic sign of infection, as it indicates that the body is responding to an invading pathogen. When an infection occurs, the immune system activates and often raises the body's temperature in an effort to help fight off the infection. Home Health Aides should monitor clients for a rise in body temperature, often above the normal range, as it is a clear indicator that something may be wrong.

In the context of other choices, dry skin does not directly indicate an infection; it may be more related to dehydration or skin conditions. An increased appetite might suggest well-being or recovery rather than infection, and improved mobility typically indicates that a client is recovering or stable, rather than showing signs of an infection. Recognizing these signs is crucial for timely intervention and treatment in home health care settings.
