Which of the following would not be an indicator of phlebitis?

In evaluating the indicators of phlebitis, it's essential to understand the typical symptoms associated with this condition. Phlebitis typically involves inflammation of a vein, which manifests through several specific physical signs. Pain and tenderness at the site, redness and swelling, and hardening of the vein are all direct reflections of inflammation and irritation within the vascular tissue.

Increased appetite, however, is not an indicator of phlebitis. While changes in appetite can occur for a variety of medical reasons, they do not directly relate to the localized inflammation and symptoms associated with phlebitis. The focus in diagnosing phlebitis is on the clinical signs observed at the vein site, which are clearly not related to appetite. Therefore, recognizing that increased appetite is not relevant to phlebitis helps in understanding the difference between systemic symptoms and those specifically tied to venous inflammation.
