NHFD JATC MOD 3A QUESTIONS AND ANSWERS 2025 common causes of HL in adults? - ANS = *** important hearing-related case hx questions for adults: medical hx - ANS = - is there a fam hx of late onset HL? - does the pt have diabetes? hypertension? kidney disease? dementia? - is there a hx of stroke, TIA, accidents, or other trauma? - is there a hx of a serious health condition requiring ototoxic meds with long-term hospitalization, or cancer treatments? important hearing-related case hx questions for adults: hearing status - ANS = - how long has the hearing difficulty been noticed - has there been occupational or recreational hx of noise exposure? - does the pt also experience tinnitus or dizziness? - what situations present the most/least difficulty for the person ? - does the person use a HA or assistive device? perceived benefit? - is the device functioning properly? important hearing-related case hx questions for adults: subacute care consideration - ANS = - what is the pt's dx? secondary or tertiary dx? - is there anything in the chart that may be a red flag for HL? - is there a pharmacological potential for HL that may or may not have been discussed w/ the pt? - do you see HAs? do not assume that if a pt has HAs that they will be in their ears - facture/trauma to the temporal bone - often part of multisystem trauma - intracranial injuries can impair cogn fn & cause neurologic deficits, potentially delaying accurate hearing assessments - ANS = temporal bone injury bone on sides & base of skull that houses IE structures (cochlea & vestibular system) & parts of the auditory pathway (8th nerve) - ANS = temporal bone temporal bone trauma: - mechanical forces from blunt/penetrating traume &/or pressure wave from a blast can ... - ANS = damage delicate auditory structures temporal bone trauma: possible effects on auditory system - outer ear - ANS = - debris - tears temporal bone trauma: possible effects on auditory system - middle ear - ANS = - ruptured TM - ossicular disarticulation (CHL) temporal bone trauma: possible effects on auditory system - inner ear - ANS = - cochlear injury - vascular compromise - trauma to 8th nerve (SNHL) temporal bone trauma: possible effects on auditory system - auditory cortex - ANS = - temporal lobe lesions - corpus callosum dammage (aud processing) types of fractures that affect auditory system - TBI may cause damage to the CANS that's not detectable on MRI - ANS = 1. longitudinal temporal bone fracture 2. transverse temporal bone fracture 3. otic capsule bone fracture types of fracture that affect the auditory system - longitudinal temporal bone fracture - ANS = most common type of petrous temporal fracture - runs parallel to long axis of petrous temporal bone - fractures can start at EAC or mastoid types of fracture that affect the auditory system - longitudinal temporal bone fracture: common effects - ANS = - usually causes CHL - damages ossicles & TM - IE (otic capsule) is typically spared types of fracture that affect the auditory system
