Question

when obtaining venous blood with a vacuum tube, the tip of the needle should be inserted into the vein at a ____ degree angle
a 90
b 60 - 75
c 30 - 45
d 15 - 30

Explanation:

When using a vacuum tube for venous blood collection, a 15 - 30 degree angle is standard. A 90 - degree angle (Option A) is too steep and may cause damage. Angles like 60 - 75 (Option B) or 30 - 45 (Option C) are not the typical recommended. A 15 - 30 degree angle (Option D) allows for proper insertion into the vein without excessive trauma.

Answer:

D. 15 - 30
