A school nurse is screening a child for scoliosis. Which instruction should the nurse give the child for this examination?

A. "Touch your chin to your chest, and then look up at the ceiling.": This movement assesses cervical range of motion, not spinal curvature. It does not allow the nurse to observe for lateral spinal deviations or rib hump associated with scoliosis. B. "Bend forward from the waist with your head and arms downward.": This is the Adam’s forward bend test, the standard screening method for scoliosis. Bending forward accentuates spinal asymmetry, making lateral curvature and rib humps more visible, which helps detect structural scoliosis effectively. C. "Turn to the side, and remain in a relaxed position.": Standing sideways may help assess posture in a frontal plane but does not reveal rotational deformities or rib prominence, which are critical indicators of scoliosis during screening. D. "Lie prone on the examination table.": Prone positioning does not allow for gravity-dependent visualization of spinal curvature or rib cage asymmetry. It limits the ability to detect scoliosis, as the forward bend test is required to accentuate spinal deviations.
