When is it most appropriate to apply the constricting band during the IV procedure?

After cleansing the venipuncture site
Before you cleanse the venipuncture site
Only if there is excessive bleeding
After inserting the needle

The correct answer is: Before you cleanse the venipuncture site

Applying the constricting band before cleansing the venipuncture site is appropriate because it helps engorge the veins, making them more visible and easier to puncture. When the constricting band is applied first, it allows for optimal venous dilation, which increases the likelihood of successful venipuncture on the first attempt. Following this, the venipuncture site can then be properly cleansed to minimize the risk of infection. It is crucial to maintain the sequence of the procedure; therefore, cleansing after the application of the band ensures that the site is prepared without losing the benefit of the constricted vein, which could happen if the band were applied later in the process. This sequence also underscores the importance of maintaining aseptic technique, where the cleansing of the site is effectively done after the vein has been made more prominent by the constricting band.
