When performing a capillary puncture the medical assistant should not take precautions to avoid using the thumb?
When performing a capillary puncture, medical assistants should avoid using the thumb because it has a thicker skin and a greater concentration of fatty tissue, which can lead to inaccurate test results. Additionally, the thumb has a strong pulse and can cause excess blood flow, complicating the collection process. Using the side of the finger, typically the ring or middle finger, is preferred for a more reliable sample. This helps ensure that the blood collected is representative of the patient's overall condition.
