Hearing Loss: Conductive Vs Sensorineural

By the end of this lesson you will be able to: - Trace sound through the outer, middle and inner ear and name where a conductive, a sensorineural and a mixed loss arises. - Perform and interpret Weber and Rinne tests with a 512 Hz tuning fork, and state when the result cannot be trusted. - Match common causes to the pattern they produce: cerumen, otitis media with effusion, otosclerosis and perforation (conductive); presbycusis, noise, ototoxic drugs, Ménière disease, acoustic neuroma and sudden sensorineural loss (sensorineural). - Recognize sudden sensorineural hearing loss as an urgent, same-day problem, and name who you notify and why the clock matters. - Identify the red flags that change urgency: sudden onset, unilateral or asymmetric loss, vertigo, focal neurological signs, bilateral or recurrent sudden loss. - Monitor and teach patients who receive aminoglycosides, cisplatin, loop diuretics or high-dose acetylsalicylic acid (ASA). - Adapt communication, support hearing aid use, and explain cochlear implants at a nursing level. - Describe newborn and early-childhood hearing screening in Canada, with Ontario as the worked provincial example, and the link...
