What might indicate an IV infection?

An indication of an IV infection is typically demonstrated by redness and swelling at the IV site. These signs suggest inflammation and potential infection as the body's immune response activates in response to bacteria or other pathogens entering through the IV line.

When an IV infection occurs, the skin around the insertion site may become red due to increased blood flow as the body's defense mechanisms engage. Swelling can also occur as the area becomes inflamed and the body's tissues react to the infection. These symptoms are critical for healthcare providers to assess as they can lead to more serious complications if not addressed promptly.

Other choices, such as increased blood pressure, decreased heart rate, and increased urine output, do not specifically signify an infection in the context of IV therapy. For example, increased blood pressure may not correlate with local infection and can result from a variety of factors unrelated to the IV site itself. A decreased heart rate typically does not indicate infection; rather, it could suggest different underlying health issues or reactions. Increased urine output can be influenced by various factors, including fluid administration and medication effects, but does not directly point to an IV infection. Hence, redness and swelling at the IV site are crucial signs to monitor for infection.
