The nurse is performing an otoscopic examination on an adult. Which of these actions is correct?

A. Smallest speculum: The smallest speculum may not provide the best view of the ear canal and tympanic membrane, especially in adults. The correct size should be chosen for adequate visualization. B. Releasing the traction: Traction should be maintained to stabilize the ear and allow a better view of the ear canal. C. Tilting the person's head forward: This is not the ideal positioning for the ear examination. The head should be tilted slightly away to straighten the ear canal. D. Pulling the pinna up and back: This helps straighten the ear canal, especially in adults, providing better visualization during the otoscopic examination.
