Practical Exam-Hearing Aid Dispenser Questions With Solved Solutions Already Graded A+

Practical Exam-Hearing Aid Dispenser Questions With Solved Solutions Already Graded A+ Better sound localization, better hearing in background noise, the ability to focus one sound over another, sounds appear louder, better peach comprehension. List at least 3 advantages of Binaural Hearing over a monaural fitting: 1. Noise induced HL 2. Noise trauma 3. Presbycusis 4. Congenital HL 5. Syndromic HL (Waardenburg, Treacher Collins, Usher, and branchio-oto-renal) 6. Nonsyndromic HL 7. Sudden HL or sudden deafness 8. Meniere's Syndrome 9. Cranial Trauma 10. Ototoxic drugs Causes of S/N hearing loss include: A. reduced audibility and intelligibility 1. poor frequency selectivity 2. reduced dynamic range 3. SNHL elevates thresholds but tolerance for loud sounds is unchanged relative to normal B. Recruitment 1. an exaggerated perception of loud sounds (abnormal loudness growth) 2. Important to measure UCLs at multiple frequencies to accurately measure dynamic range. A. reduced audibility and intelligibility 1. poor frequency selectivity 2. reduced dynamic range 3. SNHL elevates thresholds but tolerance for loud sounds is unchanged relative to normal B. Recruitment 1. an exaggerated perception of loud sounds (abnormal loudness growth) 2. Important to measure UCLs at multiple frequencies to accurately measure dynamic range. Effects of S/N hearing loss include: Obtaining accurate information to determine if a referral is required. A. Medical Determine: 1. Stroke, arthritis, nephropathy, dementia, Alzheimer's 2. Head injuries 3. Family history of hearing loss 4. Past surgeries 5. Checking for any of the RED FLAG CONDITIONS. B. Otological C Pharmacological D. Previous amplification history E. Patient attitudes and expectations. What is the benefit of obtaining a PATIENT CASE HISTORY? 1. Visible congenital or traumatic deformity of the ear. 2. History of active drainage from the ear in the previous 90 days. 3. History of sudden or rapidly progressive hearing loss within the previous 90 days. 4. Acute or chronic dizziness. 5. Unilateral hearing loss of sudden or recent onset within the previous 90 days. 6. Audiometric air-bone gap equal to or greater than 15 decibels at 500 Hz, 1,000 Hz, and 2,000 Hz. 7. Visible evidence of significant cerumen accumulation or a foreign body in the ear canal. 8. Pain or discomfort in the ear. List the 8 red flag conditions 1. Proper bracing technique (hands and head move as one) 2. 3. . Landmarks on the TM . 4 quads of the TM List the steps involved with otoscopic inspection of the ear Five reasons to perform otoscopy. (purpose and conditions) 1. Reveal any medical conditions which require a medical referral. 2. Inspect ear canal. Wax, foreign objects, growths. 3. Inspect back of pinna for surgical scars, lesions, skin disorders. 4. Verify ear canal is clean and TM is healthy. 5. Note any unusual landmarks. 1. Otalgia-Pain 2. Otorrhoea-Discharge 3. Hearing Loss 4. Tinnitus 5. Vertigo Five symptoms of ear disease 1. Disinfect work area 2. Check equipment for static, crackling, or distortion. 3. Sound check: Sweep all of the frequencies and intensity levels. Listen for any anomalies. 4. Calibrate mic to the head set. 5. Speech calibrations. Explain steps involved in daily biological check: Recite instructions for A/C testing Recite instructions for B/C testing "I need to use this light to look in your ears. It might be uncomfortable, but it shouldn't hurt. I just need to take a peek at your ear canal and ear drum and make sure it's ok to test your hearing. Please hold still while I take a look." Recite the instructions before performing an otoscopy. Deliver narrow band masking noise to the non-test ear when there is a 40 dB difference (headphones) or 70 dB (inserts ear phones) between the ears at any frequency. Rule for masking Air Conduction: Deliver narrowband noise masking to the NTE when there is a 15 dB or greater difference between the measured AC and BC thresholds of the TE @ 500, 1000, 2000, or 4000 Hz. (an Air-Bone Gap) Rule for masking for bone conduction Deliver speech spectrum masking noise to the NTE when the difference between the unmasked measured SRT of the TE and the best BC threshold of the NTE at 500, 1000, 2000, or 4000 Hz exceeds 60 dB. Rule for masking SRT: Tell me why obtaining patient information is important. To determine whether or not the patient should be referred to a dr. What is the most important goal when obtaining patient information? Obtain info about patient's 1. Lifestyle 2. Family history-with H.L./other relevant medical issues. 3. Medications 4. Mental impairments 5. Patient concerns 6. What are we looking for when we look a patients intake sheet? To be able to focus our attention on counselling a patient's realistic expectations. To be able to offer the best products and/or accessories to meet their needs. To create a relationship of trust and confidence to better serve each patient. Why is it important to know what a patient's communication goals are? Otosclerosis. Including stapedial fixation and other mechanical factors. Stapondectomy surgery is a possible remedy. Carhart's Notch. What type of hearing loss is shown in the image? Cookie Bite Audiogram. Name for the audiometric pattern often seen with congenital hearing loss What type of hearing loss is shown in the image? Tympanogram that suggests: "little or no eardrum movement". Type B Tympanogram-Type B indicates little or no eardrum movement suggesting fluid in the middle ear space. Type A sub s Tympanogram-May result in Air-Bone gaps, Can be seen w/ otosclerosis or ossicular fixation. "Low compliance, stiff compliance findings" What type of tympanogram is shown? What are the reasons for this type of test result?
