What are common signs of infection to watch for?

The signs of infection commonly observed in patients include redness, swelling, warmth, and discharge. These symptoms are indicative of the body's inflammatory response to an infection. When tissue becomes infected, blood flow increases to the area, causing redness and warmth. Swelling occurs as fluid and white blood cells accumulate, and discharge may arise from pus if the infection is significant. Recognizing these signs is crucial for timely intervention and treatment, which can help prevent the spread of infection and promote recovery.

The other options do not accurately represent the hallmark signs of infection. While headaches and fatigue can be associated with various illnesses, they are not specific to infections. Dry skin and a mild cough are similarly vague and may occur for reasons unrelated to infection. Finally, stable vital signs and clear skin suggest a lack of infection rather than its presence. Thus, awareness of the specific signs outlined in the correct answer is essential for effective monitoring and care in a healthcare setting.
