Answer 1

Answer: Do not puncture the fifth or little pinky finger- tissue between the skin surface and bone is thinnest in the finger and bone injury is likely.

(The little finger has the thinnest bone and when we puncture it, it may cause serious injury to the bone. So, it should not be puncture.)

Do not puncture the index finger - It is usually more calloused and harder to puncture, more sensitive to puncture.

( The index finger is more sensitive and can be hard to puncture. So, it should not be punctured.)

Do not puncture the side or very tip of the finger -the distance between skin surface and bone is half as much as in the central fleshy portion.

( The tip of the finger has fleshy portion which may cause Injury.)

Do not puncture the thumb- It has a pulse, indicating an artery in the puncture area.

( The thumb indicates the artery in the punctured areas so the thumb should not be punctured.)
