Florida Nursing Assistant Competency Pracrice Exam

Signs of infection that a nursing assistant should observe for include redness, swelling, warmth, and discharge at the site. These signs indicate that the body is responding to an infection. Redness, often referred to as erythema, occurs due to an increase in blood flow to the affected area as part of the inflammatory response. Swelling, or edema, results from fluid accumulation that can occur when tissues are inflamed. Warmth is a consequence of increased blood flow and metabolic activity in the area of infection. Discharge, which can be purulent (pus-like) or serous (clear fluid), frequently indicates that the body is attempting to expel pathogens or irritants. Recognizing these specific signs enables nursing assistants to identify potential infections early and facilitate appropriate medical interventions.

In contrast, itching and dryness typically relate to skin irritation rather than infection. Frequent headaches can stem from various non-infectious causes, such as stress or dehydration. Low energy and sleepiness may indicate fatigue or other conditions, but they are not specific indicators of infection. Understanding the hallmark signs of infection is crucial in nursing care for promoting patient safety and timely treatment.
