In terms of IV catheter anatomy, what does a "long bevel" facilitate?

A long bevel on an IV catheter facilitates easier insertion and reduces trauma to the surrounding vascular tissue. The design of the long bevel allows for a smoother entry point as the catheter is advanced into the vein. This design minimizes the likelihood of tearing or puncturing the vessel wall, creating a more comfortable experience for the patient and promoting better vascular access.

Additionally, a long bevel often results in a tapered end that enables the catheter to glide through the skin and into the vein with less force, which decreases the potential for discomfort and minimizes the risk of complications during insertion. This characteristic is particularly vital in settings where frequent venipuncture is required, as it can contribute to improved patient outcomes and experience.

The other options do not accurately capture the primary benefit that a long bevel provides. For instance, while visibility and fluid flow resistance are important considerations in IV therapy, they are not directly impacted by the bevel’s design.
