A 4-month-old infant with low birth weight who passed a neonatal hearing screening fails to localize environmental sounds. The most appropriate recommendation is?

• A. Consideration of auditory amplification
• B. Hearing-loss counseling for the parents
• C. Careful parent monitoring of the child's speech-language development
• D. Evaluation of auditory function by an audiologist

Answer: (D)

The key concept here is that a newborn who passes initial hearing screening can still have a hearing problem, especially when later behavior raises concern about auditory performance. Localizing environmental sounds requires clear hearing across both ears and intact neural processing from the cochlea to the brain. In a 4-month-old with low birth weight, failing to localize sounds suggests possible hearing impairment or other auditory system issues, so the appropriate next step is a formal evaluation of auditory function by an audiologist. This evaluation uses age-appropriate, objective tests (such as auditory brainstem response or otoacoustic emissions) to determine whether there is a hearing loss, its type (conductive or sensorineural), and its degree, which then guides timely intervention.

Starting with an audiologist ensures an accurate diagnosis and appropriate plans, including amplification if a loss is confirmed. Counseling parents and monitoring language development remain important, but they depend on knowing the child’s actual hearing status. Without a formal assessment, assumptions about normal hearing could delay necessary intervention.
