What should a correctly placed IV not show signs of?

A correctly placed IV catheter should not exhibit signs of swelling, redness, or pain at the insertion site or along the vein. These symptoms are indicative of possible complications such as infiltration, phlebitis, or infection. When the IV is properly placed, there should be minimal reaction, and the surrounding tissues should remain healthy. The absence of swelling, redness, or pain suggests that the IV is functioning appropriately, allowing for effective fluid administration without causing irritation or trauma to the vascular system.

In contrast, the other answer choices refer to potential complications that can arise with IV placement. For instance, swelling and discomfort may occur with infiltration, where the fluid leaks into surrounding tissues. Difficulty in drawing blood could result from an improper placement or blockage within the catheter, while a change in fluid color may indicate contamination or a reaction within the IV setup. Overall, the correct response emphasizes the ideal condition of an IV site following a successful placement.
