Which of the following lancet positions should a phlebotomist use for a capillary blood collection on a healthy adult patient?

Positioning the lancet parallel to the nail bed deviates from the optimal angle for capillary blood collection. This orientation may lead to suboptimal blood flow and difficulty in obtaining an adequate sample volume due to the lack of direct access to the capillary network.

Choosing to collect capillary blood along the lateral portion of the first digit introduces unnecessary variability in sampling technique. This location may not consistently yield the desired blood volume for testing purposes, potentially resulting in inadequate or unreliable results.

Selecting the medial portion of the fifth digit for capillary blood collection deviates significantly from the standard practice. This position is less conducive to efficient blood flow and may cause discomfort to the patient due to the increased distance from the capillary network in the fingertip.
