What is a common complication of IV therapy that can be evaluated?

Thrombophlebitis is a common complication of intravenous therapy that involves inflammation of the vein and can occur when an IV is placed. It can be evaluated through clinical signs such as redness, warmth, swelling, and pain at the site of the IV insertion. The presence of a thrombus, or blood clot, can lead to discomfort and the potential for further complications if not addressed.

In contrast, oliguria, diarrhea, and hypoglycemia are not direct complications of IV therapy in the same context. Oliguria is related to decreased urine output and often relates to kidney functionality, rather than an immediate complication of IV access. Diarrhea pertains to gastrointestinal issues and can arise from a variety of factors including infections, diet, or medications but is not typically associated with IV therapy itself. Hypoglycemia refers to low blood sugar levels, which, while potentially influenced by IV fluid solutions (like those containing glucose), is not a complication evaluated at the IV site or related to vein inflammation.
