A mother notices that her newborn is able to sleep without waking even when in the nursery with other newborns crying. The mother asks whether her baby might have a hearing problem, because her father wears hearing aids
The nurse should explain that: 1. Newborn risk factors associated with potential hearing loss do not include a family history of hearing loss.
2. Newborns cannot hear, due to mucus accumulated in the middle ear, which takes several days to drain.
3. Newborns who are asleep do not respond to loud noises that are not accompanied by vibrations.
4. Newborns in a noisy nursery are able to habituate to the sounds, and might not react unless a sound is sudden or much louder.
4
Rationale 1: Risk factors associated with potential hearing loss include a history of hearing loss in the family.
Rationale 2: Following the first cry, the newborn's hearing becomes acute as mucus from the middle ear is absorbed.
Rationale 3: The newborn's hearing initially can be evaluated by response to loud or moderately loud noises unaccompanied by vibrations.
Rationale 4: Habituation is the infant's ability to diminish innate responses to specific repeated stimuli.
