Venipuncture Technique: Bevel Up or Down?
What is the correct technique for performing a venipuncture on a deep median cubital vein?
A. Bevel up at 25-30 degrees
B. Bevel down at 10-15 degrees
C. Bevel up at 10-15 degrees
D. Bevel down at 25-30 degrees
Final answer: C. Bevel up at 10-15 degrees
Answer:
For a venipuncture performed on a deep median cubital vein, the correct approach is to have the needle's bevel up at an angle of 10-15 degrees to ensure smooth entry and avoid damage to the vessel walls.
When you are performing venipuncture on a deep median cubital vein, the correct technique is to have the bevel facing up at an angle which allows for the smooth entry of the needle into the vein without damaging the vessel walls. Therefore, the answer to the question is C. Bevel up at 10-15 degrees.
Having the bevel up at a slight angle minimizes the risk of passing through the opposite vessel wall and optimizes the chance of a successful puncture. This method also helps in preventing unnecessary discomfort to the patient.
