Verified step by step guidance

Understand the purpose of the Weber and Rinne tests: Both are used to evaluate hearing and differentiate between conductive and sensorineural hearing loss.

Identify the tool used in these tests: A tuning fork is used because it produces sound waves at a specific frequency, which is essential for assessing hearing function.

Learn how the Weber test is performed: The tuning fork is struck and placed on the midline of the patient's forehead or on top of the head. The patient is asked where they hear the sound best, which helps determine the type of hearing loss.

Learn how the Rinne test is performed: The tuning fork is struck and placed on the mastoid bone behind the ear until the sound is no longer heard. Then, it is moved next to the ear canal. The patient is asked which position they hear the sound better, helping to assess air conduction versus bone conduction.

Recognize why other tools are not suitable: An otoscope is used for visual examination of the ear canal, a stethoscope is used for listening to internal body sounds, and a sphygmomanometer is used for measuring blood pressure. None of these tools produce sound waves like a tuning fork.
