Question

24 multiple choice 1 point which digit of the hand produces the greatest oid in the lateral projection that digit? third digit fifth digit second digit first digit 25 multiple choice 1 point for lateral projections of the second through fifth digits of the hand, through which joint should the central ray be directed? proximal interphalangeal caropmetacarpal metacarpophalangeal distal interphalangeal

Explanation:

For question 24, the fifth digit (little - finger) is furthest from the image receptor in a lateral projection of the hand, thus producing the greatest object - image distance (OID). For question 25, for lateral projections of the second through fifth digits of the hand, the central ray should be directed through the proximal interphalangeal joint.

Answer:

1. B. Fifth digit
2. A. Proximal interphalangeal
