Which of the following is true about the angle of needle insertion during venipuncture?

The angle of needle insertion during venipuncture is critical in ensuring successful access to a vein while minimizing complications. The correct range of 15-30 degrees allows for optimal entry into the vein.

Inserting the needle at this angle increases the likelihood of the needle penetrating the vein without passing all the way through it, which can happen if the angle is too steep or too shallow. If the angle exceeds 30 degrees, there is a higher risk of damaging the surrounding tissue and making insertion more difficult. Conversely, a steeper angle could make it challenging to access the vein effectively and can lead to complications such as hitting an artery or causing unnecessary discomfort to the patient.

Overall, maintaining an insertion angle between 15-30 degrees strikes a balance that provides sufficient access to the vein while reducing the risk of trauma and ensuring a more comfortable experience for the patient.
