A nurse is preparing to conduct an audiometry test on a client who reports difficulty hearing in noisy environments. Which nursing action best supports obtaining accurate results during this assessment?

A. Use otoscope examination first to identify any external ear obstructions before conducting audiometry is incorrect as the first step for obtaining accurate audiometry results. While inspecting the ear canal for wax, infection, or foreign objects is important, it does not directly affect the accuracy of the audiometry test if the client has no obstruction. Otoscopic examination is a preliminary assessment, not the key action for test accuracy. B. Instruct the client to indicate hearing the tone by saying "yes" aloud to maintain clear communication is incorrect because verbal responses can introduce visual or auditory cues that may bias the results. Clients are typically asked to respond by raising a hand or pressing a button, which avoids influencing the examiner or altering test reliability. C. Ensure the client wears the audiometer headphones correctly and faces away from the examiner during the test is correct because proper headphone placement ensures the tones are delivered accurately to the correct ear, and facing away prevents the client from seeing the examiner’s cues. This reduces bias and ensures reliable and valid audiometric results, which are crucial for diagnosing hearing deficits. D. Perform the test in a room with ambient noise to simulate real-world hearing conditions is incorrect because audiometry must be conducted in a quiet, soundproof environment to avoid interference from background noise. Accurate measurement of hearing thresholds requires minimizing external sounds.
