Which instrument should the practical nurse (PN) obtain for the Advanced Practice Registered Nurse (APRN) who is preparing to conduct a Weber test?

A. Reflex hammer: A reflex hammer is used to assess deep tendon reflexes and is not needed for hearing tests like the Weber test. B. Tuning fork: The Weber test evaluates bone conduction of sound to detect unilateral hearing loss. A tuning fork is the appropriate instrument to perform this test. C. DinamapR: This device measures blood pressure and has no application in conducting auditory assessments such as the Weber test. D. Doppler: A Doppler device is used to assess blood flow and pulses, not for auditory testing, and would not be useful in performing the Weber test.
