What indication would NOT suggest a successful IV placement?

The presence of patient discomfort at the IV insertion site is an indication that suggests a potential problem with the IV placement. While some discomfort can be expected with any IV insertion, significant or persistent discomfort could indicate complications such as infiltration, phlebitis, or an incorrect placement in the subcutaneous tissue rather than the vein. Therefore, when evaluating the success of an IV placement, a patient's discomfort is a red flag that warrants further assessment.

In contrast, immediate blood return upon aspiration indicates that the IV catheter is positioned within the vein, which is a sign of successful placement. Absence of swelling at the insertion site suggests that there is no infiltration or fluid accumulation around the IV site, further implying that the placement is secure and effective. Lastly, fluids infusing at the desired rate demonstrates that the IV is patent and functioning as intended. Each of these factors supports the notion of a successful IV placement, while discomfort signals potential issues needing attention.
