A nurse is caring for a newborn and assessing newborn reflexes.
To elicit the Babinski reflex, the nurse should take which of the following actions?

Tickle the outer edge of the sole of the newborn’s foot moving up toward the toes.

Turn the newborn’s head quickly to one side.

Hold the newborn vertically allowing one foot to touch the table surface.

Clap near the crib and make a loud noise.

Answer and Explanation

The Correct Answer is A

Choice A rationale

The Babinski reflex is elicited by stroking the outer edge of the sole of the newborn’s foot, moving up toward the toes. This causes the big toe to move upward and the other toes to fan out.

Choice B rationale

Turning the newborn’s head quickly to one side is used to elicit the tonic neck reflex, not the Babinski reflex.

Choice C rationale

Holding the newborn vertically and allowing one foot to touch the table surface is used to elicit the stepping reflex, not the Babinski reflex.

Choice D rationale

Clapping near the crib and making a loud noise is used to elicit the startle (Moro) reflex, not the Babinski reflex.

Correct Answer is A

Explanation

Choice A rationale

Placing a baby on their back to sleep significantly reduces the risk of SIDS. This position helps keep the airway open and reduces the risk of suffocation.

Choice B rationale

There is no direct correlation between SIDS and the diphtheria, tetanus, and pertussis vaccines. Vaccines are safe and do not increase the risk of SIDS3.

Choice C rationale

SIDS rates have actually decreased over the last 10 years, largely due to public health campaigns promoting safe sleep practices.

Choice D rationale

Sleep apnea is not the main cause of SIDS. The exact cause of SIDS is unknown, but it is believed to be related to defects in the brain that control breathing and arousal from sleep.

A. Newborns are born with fully developed immune responses capable of independently fighting infections from birth. B. Newborns have a mature gut microbiome that supports their immune system immediately after birth. C. Newborns rely solely on their innate immune system without any contribution from maternal antibodies. D. Newborns receive passive immunity through the placenta and colostrum, but their own immune system is not fully functional until several months of age.

Correct Answer is D

Explanation

Choice A rationale

Newborns are not born with fully developed immune responses. Their immune system is immature and continues to develop after birth. They rely on maternal antibodies for initial protection.

Choice B rationale

Newborns do not have a mature gut microbiome immediately after birth. The gut microbiome develops over time and is influenced by factors such as breastfeeding and exposure to the environment.

Choice C rationale

Newborns do not rely solely on their innate immune system. They receive passive immunity from maternal antibodies transferred through the placenta and colostrum, which provides initial protection against infections.

Choice D rationale

Newborns receive passive immunity through the placenta and colostrum, but their own immune system is not fully functional until several months of age. This passive immunity helps protect them from infections during the early months of life.
