Phil the New Phlebotomy Tech is preparing to perform a finger stick. Phil has chosen a site located on the third finger of the non-dominant hand- just off-center of the fingertip. He is planning to puncture the finger perpendicular to the ridges of the fingerprint. What (if anything) has Phil done wrong?
  1. Phil should choose a site along the side of the finger.
  2. Phil should puncture the finger parallel to the fingerprint ridges.
  3. Phil is correct.
Explanation
Answer: C - Phil is correct in his choice of finger stick site, and his plan for angle of the puncture. The third and fourth fingers of the non-dominant hand are less likely to contain callused skin. The puncture site should avoid the sides of the fingertip because underlying structures are close to the surface in that area. Puncturing the finger perpendicular to the ridges of the fingerprint prevents the blood from running down the ridge and aids in collection.
