Question

Quizplus · Accepted Answer

The ring finger, perpendicular to the ridges, is the most appropriate dermal puncture site for adults because it has good blood flow and is less painful than other fingers. The fleshy center of the thumb and thumb side of index finger have too much tissue and bone, making it difficult to obtain an adequate blood sample. The middle finger, parallel to the ridges, can cause more pain and discomfort due to the nerve endings being closer to the surface of the skin.
