A Weber test that lateralizes to the deaf ear with a Rinne test that is negative detects which kind of hearing loss?a) Conductiveb) Sensorineuralc) Electricald) Hystericale) SemanticCorrect Answer: a) Conductive hearing loss.1) If Weber's lateralises to the LEFT, then EITHER there is a CONDUCTIVE hearing loss on the LEFT, or there is SENSORINEURAL deficit on the RIGHT.2) If Rinne's test on the left is NEGATIVE, then there is CONDUCTIVE hearing loss on the LEFT. 3) If Rinne's test on the LEFT is POSITIVE, then there is likely SENSORINEURAL deficit on the RIGHT.
