The AP projection oh the forearm must be made with the hand:
- a. In radial flexion
- b. In ulnar flexion
- c. Pronated
- d. Supinated
The correct answer is d. Supinated.
The AP projection of the forearm is made with the hand supinated so that the radius and ulna are parallel to the X-ray beam. This allows for a clear visualization of the bones of the forearm.
The other options are incorrect:
- a. In radial flexion would position the hand in an unnatural position and would not provide a clear visualization of the bones of the forearm.
- b. In ulnar flexion would position the hand in an unnatural position and would not provide a clear visualization of the bones of the forearm.
- c. Pronated would position the radius and ulna at an angle to the X-ray beam, making it difficult to visualize the bones of the forearm clearly.
