Which factor increases the risk of peripheral IV complications?

Rationale: A. Using a stabilization device is incorrect because stabilization devices secure the catheter, reduce movement, and help prevent mechanical complications such as infiltration or dislodgement. This practice reduces, rather than increases, risk. B. Frequent site assessment is incorrect because regularly checking the IV site allows for early detection of complications such as infiltration, phlebitis, or infection. This practice prevents complications rather than increasing risk. C. Prolonged catheter dwell time is correct because leaving a peripheral IV catheter in place for an extended period increases the risk of infection, phlebitis, thrombosis, and infiltration. Most guidelines recommend routine site rotation every 72–96 hours for adult patients, unless clinically indicated otherwise. D. Using the smallest gauge catheter possible is incorrect because smaller-gauge catheters minimize vein trauma and reduce the risk of mechanical complications, such as phlebitis or infiltration. Using an appropriately sized catheter is a protective measure.
