Which of the following statements is true regarding placement of a constricting band when initiating IV access in the hand or arm? A) The constricting band should be just tight enough to impede arterial blood flow without restricting venous passage.
B) The constricting band should be just tight enough to impede venous blood flow without restricting arterial passage.
C) The constricting band should be placed distal to the intended site of puncture.
D) Never leave the band in place for more than three minutes.

B) The constricting band should be just tight enough to impede venous blood flow without restricting arterial passage.

Explanation:

The constricting band, when used, has the main objective of limiting blood flow, for this reason, it must be placed on the arm with a certain pressure that allows this band to be tight. However, care must be taken with the amount of pressure applied to the band, as the goal is to block blood flow in an influential manner, but not to completely block arterial passage.
