A nurse is assisting with screening a client for scoliosis. Which of the following actions should the nurse ask the client to perform?

A. Bend forward with back parallel to the floor: The forward bend test, or Adam’s test, allows the nurse to observe for asymmetry of the ribs or spine, which are common indicators of scoliosis. This position accentuates spinal curvature for easier assessment. B. Stand facing the nurse: Observing the client from the front does not provide a clear view of spinal curvature or asymmetry of the shoulders, ribs, or scapulae, which are key findings in scoliosis screening. C. Lie supine with arms extended above head: This position is not effective for detecting spinal curvature or rib asymmetry, as scoliosis is best visualized with the client standing and bending forward. D. Lie in a side-lying position: The side-lying (lateral) position is used for assessing pressure ulcers or administering enemas, but it does not provide the necessary alignment or visual access to detect the "S" or "C" curve of the spine characteristic of scoliosis.
