A nurse is performing an assessment of a newborn's Babinski reﬂex. Which of the following findings should the nurse expect?

Flexion of the forearm.

Downward curl of the toes.

Dorsiﬂexion of the great toe.

Extension of the leg.

Answer and Explanation

The Correct Answer is C

The Babinski reﬂex, also known as the plantar reﬂex, is a normal reﬂex in infants
that occurs when the sole of the foot is stroked from heel to toe.

In response to this stimulus, the big toe moves upward or toward the top surface of the foot and the other toes fan out.

Choice A is not an answer because ﬂexion of the forearm is not a response to stimulation of the foot.
Choice B is not an answer because downward curl of the toes is not a response
to stimulation of the foot.
Choice D is not an answer because extension of the leg is not a response to
stimulation of the foot.

Correct Answer is B

Explanation

A newborn who was exposed to cocaine in utero may exhibit a high-pitched cry as well as other symptoms such as irritability, tremors, and feeding difficulties.

Choice A is not an answer because hypotonicity is not a common ﬁnding in newborns exposed to cocaine in utero.

Choice C is not an answer because increased head circumference is not a common ﬁnding in newborns exposed to cocaine in utero.

Choice D is not an answer because decreased startle response is not a common ﬁnding in newborns exposed to cocaine in utero.

A. Rust-stained urine. B. Subconjunctival hemorrhage. C. Single palmar creases. D. Transient circumoral cyanosis.

Correct Answer is A

Explanation

Rust-stained urine.

Rust-stained urine in a newborn can be a sign of a serious medical condition and should be reported to the provider.

Choice B is not the answer because subconjunctival hemorrhage in a newborn is usually normal and harmless.

It may be caused by pressure changes during vaginal delivery and will disappear on its own after two or three weeks.

Choice C is not the answer because single palmar creases develop while a baby

is growing in the womb and appear in about 1 out of 30 people.

While some single palmar creases may indicate problems with development and be linked with certain disorders, it is not necessarily a cause for concern.

Choice D is not the answer because transient circumoral cyanosis refers to blue discoloration around the mouth only and is usually seen in infants.

It’s often considered a type of acrocyanosis which happens when small blood vessels shrink in response to cold.

This is very normal in infants during the ﬁrst few days after birth.
