Question

what is the preferred patient position for an anteroposterior (ap) chest radiograph when the patient cannot stand?
prone
supine
semi - erect
lateral decubitus

Explanation:

In medical imaging, when a patient cannot stand for an anteroposterior (AP) chest radiograph, the supine position is commonly preferred. In the supine position, the patient lies on their back, which allows for a relatively clear AP - view of the chest while the patient is in a non - standing position. The prone position is face - down and not ideal for AP chest radiographs. The semi - erect position still requires some ability to sit up, and the lateral decubitus position is more for imaging to detect fluid levels or other lateral - specific findings rather than a standard AP view when non - standing.

Answer:

B. Supine
