Swelling and redness are important signs for CNAs to monitor as they can indicate potential skin issues. These symptoms may suggest inflammation, infection, or other underlying health problems that could lead to more serious conditions like pressure ulcers or skin breakdown. Observing the skin for changes in color and texture is crucial in providing timely interventions to maintain skin integrity and overall health.

The other choices do not directly indicate skin issues. Cool skin temperature may signify inadequate blood flow or temperature regulation problems but does not specifically point to a skin condition. An increased appetite and improved mobility are generally positive signs and may indicate better overall health, rather than concerns about skin integrity. Thus, paying attention to swelling and redness is vital for CNAs to ensure they are proactive in preventing skin complications.
