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?

Use otoscope examination first to identify any external ear obstructions before conducting audiometry.

Instruct the client to indicate hearing the tone by saying "yes" aloud to maintain clear communication.

Ensure the client wears the audiometer headphones correctly and faces away from the examiner during the test.

Perform the test in a room with ambient noise to simulate real-world hearing conditions.
