A nurse is preparing to inspect the tympanic membrane of an adult client. Which action demonstrates correct technique?

Rationale: A. Inserting the otoscope deeply into the ear canal can cause discomfort, pain, or injury to the client’s ear. Proper technique requires gentle insertion just far enough to visualize the tympanic membrane without causing trauma. B. Pulling the auricle downward and backward is appropriate for children under 3 years old, not adults. Using this technique on an adult may make visualization difficult and does not align with standard adult assessment guidelines. C. Pulling the auricle upward and backward straightens the ear canal in adults, allowing proper visualization of the tympanic membrane. This technique reduces obstruction from the canal’s natural curve and facilitates accurate assessment while minimizing discomfort. D. Asking the client to tilt the head forward is not necessary for otoscopic examination. The client should remain seated with the head in a neutral position while the nurse gently straightens the canal with the correct auricle maneuver. Tilting the head forward does not improve visualization.
