PhlebotomyQuestion 59 of 100
At what angle should the needle be inserted during a routine venipuncture?
a.45 to 60 degrees
b.Straight down at 90 degrees
c.15 to 30 degrees, bevel up
d.Parallel to the skin at 5 degrees
Explanation
The needle is inserted at a 15 to 30 degree angle with the bevel facing up during venipuncture. A shallow angle follows the path of the vein and reduces the risk of passing through it. Too steep an angle can puncture the back wall of the vein.
