Which condition is associated with an increased risk of infiltration at the IV site?

The correct choice highlights that the frequent use of IV access for blood draws can lead to an increased risk of infiltration at the IV site. This is because multiple punctures and manipulations at a single site can damage the delicate vascular structures and surrounding tissues. Over time, continual access can compromise the integrity of vein walls and lead to complications such as infiltration, where IV fluids seep into the surrounding tissues rather than remaining within the veins.

Infiltration can occur when the IV catheter becomes dislodged or if the vein itself is damaged during repeated use, particularly when blood draws are frequently performed from the same site. Each time a needle is inserted, there is a potential to disrupt the tissue and cause inflammation or make the vein less stable, further increasing the risk for complications like infiltration.

The other options, while they can relate to various complications associated with IV therapy, do not directly correlate with an increased risk of infiltration in the same manner as frequent blood draws do. Frequent IV site changes, for instance, might actually mitigate the risk by allowing the site to recover, while large gauge catheters are important for specific therapies and do not inherently lead to greater infiltration risks. High-pressure infusion devices can cause other complications but do not directly facilitate infiltration in the
