The correct angle for needle insertion during venipuncture is typically between 15 to 30 degrees, with many healthcare professionals opting for an angle near 30 degrees for optimal results. Inserting the needle at this angle allows for the bevel of the needle to smoothly penetrate the skin and the vein wall. This position helps to reduce the risk of damaging the vein and ensures that the needle enters the lumen of the vein properly, minimizing discomfort for the patient.

A steeper angle, such as 45 degrees, can increase the risk of the needle passing through the vein, which may lead to complications such as hematoma formation. On the other hand, an angle too shallow, like 20 degrees, may not penetrate the vein adequately, resulting in difficulties in accessing the blood vessel effectively.

Therefore, while both 15 and 30 degrees can be effective for venipuncture, aiming closer to 30 degrees helps ensure accuracy and patient comfort, which is why this angle is commonly endorsed in practice.
