What is the recommended angle of insertion for the dorsal (hand) vein?

• A. 5-9 degrees
• B. 20-30 degrees
• C. 0-5 degrees
• D. 10-15 degrees

Answer: (D)

When inserting into a dorsal hand vein, you want a shallow, gradual entry that follows the vein’s just-beneath-the-skin path. About 10-15 degrees is ideal. This small angle helps the needle slide into the vein without going too deep or causing excessive tissue trauma, which reduces the risk of piercing the back wall of the vein or hitting deeper structures. If you aim too steeply, you’re more likely to go through the vein or injure surrounding tissues; if you go too shallow, especially if the vein is small or collapses, entry can be difficult and you may miss the vein. Keeping the angle in this moderate range balances ease of puncture with safety and vein integrity.
