A patient undergoing a pure tone audiometry test does not respond consistently at the same decibel level for the 1000 Hz frequency during multiple presentations. What is the MOST appropriate next step for the medical assistant to take?
Recalibrate the audiometer as the inconsistent responses indicate equipment malfunction
Immediately refer the patient to an audiologist, as inconsistent responses suggest a profound hearing loss
Re-instruct the patient on how to respond and repeat the test for the 1000 Hz frequency
Increase the frequency to 2000 Hz and test the patient's response at that level
