Which fingerstick technique is correct for an adult capillary glucose?
a.Puncture the center of the fingertip parallel to the fingerprint lines
b.Puncture the side of the fleshy pad of the third or fourth finger, across the fingerprint lines
c.Puncture the tip of the fifth finger
d.Puncture the thumb because it has the best blood supply
Explanation
The side of the fleshy pad of the middle or ring finger is used, and the puncture crosses the fingerprint lines so the drop forms rather than running along a groove. The very center of the fingertip is the most nerve-dense and painful area. The fifth finger has little tissue over bone and the thumb has a pulse and thicker calluses, so both are avoided.
