Final answer:
For an otoscopic exam of school-age children, the pinna should be pulled up and back to provide better visualization of the ear canal and eardrum.
Step-by-step explanation:
During an otoscopic exam of a school-age child, the nurse should pull the pinna up and back. This maneuver helps to straighten the ear canal, providing better visualization of the eardrum. It is important to use this technique for children older than 3 years and adults, whereas for infants and children under 3, the pinna should be pulled down and back.
