The nurse is observing the MD performing an otoscopic examination on an adult. Which of these actions would the nurse determine is correct?

A. Tilting the person's head forward is not a standard technique for performing an otoscopic examination in adults. The head is generally held still or tilted slightly backward for better visualization. B. For adults, the correct method is to pull the pinna up and back to straighten the ear canal, allowing for a better view during the examination. C. The smallest speculum is not typically used for adults; a larger speculum is generally preferred for optimal visualization and to reduce discomfort. D. Traction should be maintained during the insertion of the speculum to keep the ear canal straight. Releasing traction once the speculum is inserted can lead to poor visibility and discomfort.
