After assisting with a vaginal delivery, what would the nurse do to prevent heat loss via conduction in the newborn?

Dry the newborn with a warm blanket.

Close the doors to the delivery room.

Wrap the newborn in a blanket.

Place the newborn on a warm crib pad.

Answer and Explanation

The Correct Answer is D

Choice A reason:

Drying the newborn with a warm blanket is an effective method to prevent heat loss through evaporation, not conduction. Evaporation occurs when moisture on the baby’s skin turns into vapor, which can cool the baby down. Using a warm blanket to dry the newborn helps to remove this moisture and keep the baby warm, but it does not specifically address heat loss via conduction.

Choice B reason:

Closing the doors to the delivery room helps to maintain a warm environment and prevent drafts, which can reduce heat loss through convection. Convection is the transfer of heat through air currents, and keeping the room warm can help to minimize this type of heat loss. However, this action does not directly address heat loss via conduction.

Choice C reason:

Wrapping the newborn in a blanket is another method to prevent heat loss through radiation and convection. By wrapping the baby, you create a barrier that helps to retain the baby’s body heat and protect against cooler air temperatures. While this is important for overall warmth, it does not specifically target heat loss via conduction.

Choice D reason:

Placing the newborn on a warm crib pad is the most effective method to prevent heat loss via conduction. Conduction is the transfer of heat from the baby’s body to a cooler surface. By using a warm crib pad, you ensure that the surface in contact with the baby is warm, thereby reducing the amount of heat lost through conduction. This method directly addresses the issue of heat loss via conduction and helps to keep the newborn warm.

Correct Answer is D

Explanation

Choice A reason:

Placing a finger at the base of the newborn’s toes is used to elicit the Babinski reflex, not the Moro reflex. The Babinski reflex is observed when the toes fan out and the big toe moves upward in response to stroking the sole of the foot1. This reflex is a normal finding in infants up to 2 years old and indicates normal neurological development.

Choice B reason:

Turning the newborn’s head quickly to one side is used to elicit the tonic neck reflex, also known as the “fencing” reflex. When the head is turned to one side, the arm on that side extends while the opposite arm bends at the elbow, resembling a fencing position2. This reflex is typically present from birth to about 6 months of age.

Choice C reason:

Holding the newborn vertically and allowing one foot to touch the table surface is used to elicit the stepping reflex. When the baby’s foot touches a surface, they will make stepping movements as if trying to walk3. This reflex is usually present from birth until about 2 months of age.

Choice D reason:

Performing a sharp hand clap near the infant is a method to elicit the Moro reflex, also known as the startle reflex. The Moro reflex is triggered by a sudden loud noise or a sensation of falling. The infant will respond by extending and abducting the arms, opening the hands, and then bringing the arms back to the body. This reflex is present at birth and typically disappears by 4 to 6 months of age.

A. “There is no need to worry about that. Most forms of hearing loss are not inherited.” B. “We do routine hearing screenings on newborns. You’ll know the results before you leave the hospital.” C. “The best way to determine if your baby can hear is to clap your hands loudly and see if she startles.” D. “Look at how she looks at you when you speak. That’s a good sign.”

Correct Answer is B

Explanation

The correct answer is b) “We do routine hearing screenings on newborns. You’ll know the results before you leave the hospital.”

Choice A reason:

The statement “There is no need to worry about that. Most forms of hearing loss are not inherited” is not entirely accurate. While it is true that not all forms of hearing loss are inherited, genetic factors can play a significant role in hearing loss. Approximately 50-60% of hearing loss in infants is due to genetic causes. Therefore, dismissing the concern without proper screening is not advisable.

Choice B reason:

Routine hearing screenings are conducted on newborns to detect any hearing issues early. These screenings are typically performed before the baby leaves the hospital. The two main types of newborn hearing screenings are Otoacoustic Emissions (OAEs) and Automated Auditory Brainstem Response (AABR). These tests are safe, painless, and can identify hearing loss early, allowing for timely intervention. Early detection is crucial for the development of speech, language, and social skills.

Choice C reason:

Clapping hands loudly to see if the baby startles is not a reliable method to determine hearing ability. While a startle response might indicate that the baby can hear, it does not provide comprehensive information about the baby’s hearing capabilities. Newborn hearing screenings are more accurate and can detect even mild hearing loss.

Choice D reason:

Observing how the baby looks at you when you speak is also not a reliable method to assess hearing. Babies can respond to visual cues and vibrations, which might give the impression that they can hear. However, this method does not provide a definitive assessment of the baby’s hearing ability. Professional hearing screenings are necessary to accurately determine hearing status.
