Final answer:
Prominent superficial veins in the area of planned CVAD may indicate increased pressure and the possibility of developing edema.
Step-by-step explanation:
Prominent superficial veins in the area of planned central venous access device (CVAD) may indicate increased pressure within the veins, which can lead to pooling of blood and fluid accumulation, resulting in a condition called edema. CVADs are commonly used for long-term intravenous therapy or for frequent blood sampling. It is important to assess the superficial veins before inserting a CVAD to ensure proper placement and minimize complications.
