When positioning the 2nd digit into an oblique position, which way should the digit be rolled?
pronation
laterally
supination
medially
medially
Rationale: When positioning a specific digit, position the part closest to the image receptor and keep the part parallel to the image receptor allowing the central ray to intersect perpendicular to the part. For the 2nd digit, from the pronated hand position, roll the hand toward midline or medially to keep the digit closer to the image receptor.
