| Question | Answer |
| 1. TRUE/FALSE? A. Early detection of hearing impairment is crucial because of its impact on speech outcomes. | True. Late detection often results in poor speech outcomes. |
| 1. TRUE/FALSE? B. A child should ideally be fitted with hearing aids at 12 months of age. | False. Hearing aids should be fitted before 6 months of age for optimum speech and language outcomes – see studies by Yoshinaga-Itano. |
| 1. TRUE/FALSE? C. Normal conversation occurs at 50–75 dB. | True. Threshold of hearing is 0 dB, whispering is at 20 dB, and threshold of pain is at 120+ dB. |
| 1. TRUE/FALSE? D. Auditory brainstem response testing is an objective assessment of hearing suitable for neonates. | True. Auditory brainstem response testing is a physiologic audiological assessment which can provide accurate objective measurement of hearing at any age and is the gold standard for neonatal hearing assessment. |
| 2. TRUE/FALSE? A. Permanent hearing loss in children can be caused by congenital infections, ossicleanomalies and Connexin 26 mutations. | True. Congenital infections such as cytomegalovirus are common causes of childhood hearing loss; ossicle anomalies can cause permanent conductive hearing loss; and Connexin 26 is the most common gene responsible for childhood hearing loss. |
| 2. TRUE/FALSE? B. Genetic hearing loss is always present at birth. | False. Some genes are associated with hearing loss that develops during childhood or even adulthood. |
| 2. TRUE/FALSE? C. MRI is the preferred imaging modality for sensorineural hearing loss. | True. MRI provides the best imaging of the cochlea and cochlear nerve and avoids radiation exposure. |
| 2. TRUE/FALSE? D. A family history of hearing loss is always present if the cause is genetic. | False. Most genetic hearing loss is inherited recessively, therefore they may be little or no family history of hearing loss. |
| 3. TRUE/FALSE? A. Unilateral hearing loss is not clinically significant. | False. Unilateral hearing loss is associated with speech and language delay in up to one third and up to a half experience learning difficulties at school. |
| 3. TRUE/FALSE? B. A child with unilateral hearing loss can pass VROA hearing test. | True. VROA is almost always performed in soundfield which means that it only obtains the best level of hearing ie. the better hearing ear. A normal VROA result can miss any type of unilateral hearing loss. |
| 3. TRUE/FALSE? C. Children with unilateral hearing loss do not need ongoing hearing tests. | False. Annual hearing tests are recommended because there may be deterioration in the other ear which needs to be identified early because this will change the management. |
| 3. TRUE/FALSE? D. Children with unilateral hearing loss should be offered Connexin 26 gene testing. | False. Genetic causes of unilateral hearing loss are less common and Connexin 26 does not cause unilateral hearing loss. Most genetic causes of unilateral hearing loss are syndromic. |
| 4. TRUE/FALSE? A. Children who pass SWISH never need another hearing test. | False. There are many causes of delayed onset hearing loss which will not be identified by SWISH. |
| 4. TRUE/FALSE? B. Congenital cytomegalovirus infection causes hearing loss in both symptomatic and asymptomatic babies. | True. Hearing loss due to congenital cytomegalovirus infection occurs in symptomatic babies and about 5-10% of asymptomatic babies. |
| 4. TRUE/FALSE? C. Valganciclovir is indicated in babies with congenital CMV infection and isolated sensorineural hearing loss. | False. The evidence does not support the use of valganciclovir in isolated sensorineural hearing loss associated with congenital cytomegalovirus infection and there are significant possible side effects from the use of valganciclovir. |
| 4. TRUE/FALSE? D. Psychosocial factors are important mediators of the outcome of children with hearing loss. | True. Parent adjustment is the major psychosocial factor predicting child outcomes. Other psychosocial factors can be barriers to improved outcomes if they are not addressed. |
