Question 1

Hearing loss is the most common birth defect in the United States.

Accepted Answer

Hearing loss is indeed the most common congenital condition in the United States, with about 1 to 3 out of every 1,000 babies born having detectable hearing loss in one or both ears.

Question 2

The Joint Committee on Infant Hearing (JNIH) recommends that infants diagnosed with hearing loss be enrolled in an early intervention program no later than 6 months.

Accepted Answer

The Joint Committee on Infant Hearing (JCIH) recommends that infants diagnosed with hearing loss should be enrolled in early intervention services as soon as possible but no later than 6 months of age to ensure the best possible outcomes in language, social, and cognitive development.

Question 3

Nearly 80% of children who have hearing loss have risk factors at birth.

Accepted Answer

Most children who are born with hearing loss (about 60%) have no risk factors for the condition identified at birth.

Question 4

ABRs can be used to determine how much residual hearing a child has beyond 90 dB nHL.

Accepted Answer

ABRs (Auditory Brainstem Responses) are typically used to estimate hearing sensitivity within a limited range and are most reliable for detecting hearing thresholds up to approximately 90 dB nHL. Beyond this level, the reliability decreases, making it difficult to accurately determine residual hearing.

Question 5

The startle response is fully formed at birth and lasts until about 6 months of age.

Accepted Answer

The startle response is a reflex that is present at birth and typically disappears by 6 months of age.

Question 6

Cytomegalovirus usually causes serious illness.

Accepted Answer

Cytomegalovirus (CMV) is usually asymptomatic or causes mild illness in healthy individuals, but it can cause serious illness in newborns or people with weakened immune systems.

Question 7

Nearly 40% of children who have hearing loss have an additional disability.

Accepted Answer

Many studies and reports, including those from the Centers for Disease Control and Prevention (CDC), indicate that approximately 40% of children with hearing loss also have at least one additional disability, such as cognitive, visual, speech, or motor impairments.

Question 8

A universally accepted method of screening young children does not exist.

Accepted Answer

Screening methods for young children vary widely across different countries and organizations due to differences in healthcare systems, cultural values, and available resources, leading to no universally accepted method.

Question 9

Hearing aids have proven beneficial for all children with auditory neuropathy.

Accepted Answer

While hearing aids can be beneficial for some children with auditory neuropathy, their effectiveness varies greatly among individuals due to the diverse nature of auditory neuropathy and how it affects hearing.

Question 10

When parents learn in the newborn nursery that their baby has hearing loss, the stages of grief are lessened as compared to those of parents who learn of a hearing loss later in a young child's life.

Accepted Answer

Parents who learn of their baby's hearing loss at birth can experience the same stages of grief as those who find out later. The timing of the diagnosis does not necessarily lessen the emotional impact or the stages of grief they may go through.

Question 11

When do children undergo their most intensive stage of listening speech and language development?

Accepted Answer

From birth to age 3 is considered the most intensive period for acquiring speech and language skills. This is a critical period where children are most receptive to learning language, and their brains are rapidly developing to understand and produce language.

Question 12

The National Institutes of Health call for the identification of hearing loss to occur by what age?

Accepted Answer

The National Institutes of Health recommends that the identification of hearing loss should occur by 3 months of age to ensure early intervention for better developmental outcomes.

Question 13

What is the ideal false-negative rate of a UNHS program?

Accepted Answer

The ideal false-negative rate for a Universal Newborn Hearing Screening (UNHS) program is 0, meaning that ideally, no cases of hearing impairment would be missed by the screening.

Question 14

How often should a younger child's hearing be tested after a hearing loss has been identified (assuming no other problems are present and there is no concern about the accuracy of the test results)?

Accepted Answer

For younger children with identified hearing loss, it is generally recommended to test their hearing twice a year to monitor any changes and ensure appropriate intervention and support.

Question 15

A standard ABR recording contains __________ peaks in the recorded waveform.

Accepted Answer

The answer of A standard ABR recording contains __________ peaks...

Question 16

Persons who have hearing loss of __________ dB HL or greater do not produce OAEs.

Accepted Answer

Persons with hearing loss of 30 to 40 dB HL or greater typically do not produce otoacoustic emissions (OAEs), as the inner ear's ability to generate these sounds is compromised at this level of hearing loss.

Question 17

In which hearing test might a child insert a peg into a pegboard each time they hear a tone or speech signal?

Accepted Answer

Conditioned play audiometry (CPA) is a hearing test technique used with young children where they are trained to perform an activity, such as inserting a peg into a pegboard, in response to hearing a tone or speech signal. This method makes the hearing test more engaging for children, allowing for more accurate assessment of their hearing capabilities.

Question 18

Toxemia is an example of a_____________ factor that may affect a child's hearing status.

Accepted Answer

Toxemia is a condition that can occur during pregnancy, affecting the mother's blood pressure and potentially leading to complications for both the mother and the unborn child. Since it occurs before birth, it is considered a prenatal factor.

Question 19

Cytomegalovirus is a member of the__________ family of viruses.

Accepted Answer

Cytomegalovirus (CMV) is a member of the Herpesviridae family, which also includes herpes simplex viruses, varicella-zoster virus, and Epstein-Barr virus.

Question 20

What is the most common cause of a conductive component of hearing loss?

Accepted Answer

Otitis media, an infection or inflammation of the middle ear, is the most common cause of conductive hearing loss. This condition can lead to fluid accumulation and blockage of sound transmission.
