The nurse is discussing the ears and hearing in a child with a group of peers. Which statement is most accurate related to this topic?

The eustachian tube in the infant is straighter and wider than in the adult.

Most children do not have acutely developed hearing until the age of 5 years.

The infant usually responds to sounds around the age of 6 months.

The eardrum is located between the middle and the internal ear.

Answer and Explanation

The Correct Answer is A

Choice A reason: The infant’s eustachian tube is straighter and wider, increasing susceptibility to infections due to easier pathogen access. This anatomical difference is accurate, aligning with pediatric otolaryngology evidence, making it the most correct statement about children’s ear and hearing development discussed among peers.

Choice B reason: Children’s hearing is acutely developed at birth, not delayed until age 5. Newborns respond to sounds, and hearing matures early. This statement is inaccurate, as it misrepresents the timeline of auditory development, making it incorrect compared to the eustachian tube fact in infants.

Choice C reason: Infants respond to sounds from birth, with noticeable reactions by 1-3 months, not 6 months. This statement underestimates early auditory responsiveness, making it less accurate than the eustachian tube’s anatomical description, which is a key factor in pediatric ear health discussions.

Choice D reason: The eardrum (tympanic membrane) is between the outer and middle ear, not the middle and inner ear. This anatomical error makes the statement incorrect, as the eustachian tube’s structure is the most accurate fact about children’s ear and hearing anatomy in this context.

Correct Answer is D

Explanation

Choice A reason: An electric heating pad provides dry heat, not moist heat, which is needed for deeper tissue penetration and comfort. Towels dampened with hot water deliver moist heat effectively, making this incorrect for the caregiver’s instruction on providing the recommended therapy at home for the child.

Choice B reason: Microwave-heated towels risk uneven heating and burns, making them unsafe for moist heat application. Towels dampened with hot water ensure controlled, safe moist heat, making this unreliable and incorrect for the caregiver’s home application of moist heat therapy as recommended.

Choice C reason: A hot water bottle provides dry heat, not moist, as it does not involve dampness. Towels dampened with hot water meet the moist heat requirement, making this incorrect, as it fails to deliver the specific type of heat therapy recommended for the child’s home care.

Choice D reason: Towels dampened with hot water provide safe, effective moist heat, penetrating tissues and soothing the child’s condition as recommended. This method aligns with pediatric home care instructions, making it the correct choice for teaching the caregiver about moist heat application at home.

A. Place the probe of the oximeter on the child’s chest and secure it with tape. B. Explain that pulse oximetry is done to detect respiratory retractions. C. Explain that pulse oximetry measures the oxygen saturation of arterial hemoglobin. D. Ensure the oximeter probe site is checked every 8 hours for possible reactions.

Correct Answer is C

Explanation

Choice A reason: Placing the probe on the chest is not a standard pulse oximetry site and gives inaccurate readings. Explaining the device’s purpose addresses the caregiver’s concern, making this ineffective and incorrect compared to educating about the sensor’s role in monitoring the infant’s oxygen levels.

Choice B reason: Pulse oximetry measures oxygen saturation, not respiratory retractions, which are observed visually. Clarifying its purpose reassures the caregiver, making this inaccurate and incorrect compared to explaining the device’s function to address concerns about the sensor’s use on the infant.

Choice C reason: Explaining that pulse oximetry measures oxygen saturation clarifies its importance, reassuring the caregiver about its necessity and addressing tightness concerns. This aligns with pediatric nursing education principles, making it the prioritized response to ensure compliance with monitoring the infant’s respiratory status.

Choice D reason: Checking the probe site every 8 hours prevents skin issues but doesn’t address the caregiver’s concern about tightness. Explaining the device’s purpose promotes understanding, making this secondary and incorrect compared to educating to maintain the sensor’s use on the infant.
