Quizplus · Accepted Answer

In adults and children, the usual puncture site is the ring finger, but capillary blood can be obtained from the middle finger or heel. The thumb usually is too callused, and the index finger has extra nerve endings that make the puncture more painful. The fifth finger has too little tissue for a successful puncture.
