Answer 1

For the AP projection of the scapula, the patient's arm is abducted at right angles to the body, the elbow is flexed, and the exposure is made during quiet breathing. The correct answer is D. 1, 2, and 3.

Step-by-step explanation:

For the AP (anteroposterior) projection of the scapula, certain patient positioning and techniques are necessary to obtain a clear and diagnostic image. The correct steps are:

• The patient's arm is abducted at a right angle to the body. This means the arm should be extended outwards, perpendicular to the trunk.
• The patient's elbow is flexed. This helps in keeping the arm in the correct position without tension or discomfort.
• The exposure is made during quiet breathing. This helps to minimize movement and achieve a sharper image.

In summary, all three actions described are part of the protocol for an AP projection of the scapula. Therefore, the correct answer is D. 1, 2, and 3.

Let's also consider how the scapula functions with muscle and bone interactions in the body. Protraction and retraction are movements of the scapula. Protraction of the scapula occurs when the shoulder moves forward, and retraction is when the scapula moves posteriorly and medially. Understanding the positioning and movement of the scapula can assist in performing correct patient positioning for radiologic examinations.
