Describe the signs of infection a CNA should look for.

The presence of redness, swelling, warmth, pain, and discharge are classic signs of infection. When the body is fighting an infection, the immune response triggers inflammation, which presents as redness and swelling around the affected area. Warmth is often felt due to increased blood flow as the body directs more immune cells to fight the infection. Pain may result from the inflammation itself or from the pressure that swelling puts on surrounding tissues. Discharge can indicate that the infection is producing pus or other fluids, highlighting that the body is actively responding to an infectious process.

Other options, such as increased mobility and improved appetite, suggest positive health and wellness, while dry skin and weight loss are often signs of various health issues, but not specifically indicators of infection. Normal temperature and clear breathing indicate no signs of infection, as a typical response to infection often includes fever and respiratory changes. Observing these specific signs is crucial for a CNA as part of monitoring a patient’s condition and recognizing when to report changes to a healthcare professional.
