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:

For an AP chest radiograph when a patient can't stand, the supine position (lying flat on the back) is preferred. Prone is face - down, which isn't typical for AP chest in non - standing patients. Semi - erect requires some upright ability, and lateral decubitus is for other purposes like detecting fluid levels rather than the standard AP chest when standing is not possible.

Answer:

B. Supine
