A nurse is checking the reflexes of a newborn.Which of the following actions should the nurse use to elicit the Babinski reflex?
Place the newborn supine and apply pressure to the soles of the feet.
Stroke upward on the lateral aspect of the sole of the newborn’s foot.
Pull the newborn up by the wrist from a supine position.
Touch the corner of the newborn’s mouth.
The Correct Answer is B
Choice A rationale
Placing the newborn supine and applying pressure to the soles of the feet is not the correct method to elicit the Babinski reflex. This action does not stimulate the appropriate nerve pathways involved in the reflex.
Choice B rationale
Stroking upward on the lateral aspect of the sole of the newborn’s foot is the correct method to elicit the Babinski reflex. This action stimulates the plantar reflex, causing the big toe to extend upward and the other toes to fan out.
Choice C rationale
Pulling the newborn up by the wrist from a supine position is used to elicit the traction response, not the Babinski reflex. The traction response involves the newborn flexing their arms and attempting to lift their head.
Choice D rationale
Touching the corner of the newborn’s mouth elicits the rooting reflex, not the Babinski reflex. The rooting reflex causes the newborn to turn their head toward the stimulus and open their mouth.

Correct Answer is D
Explanation
Choice A rationale
Applying a corticosteroid cream is not appropriate for acute perineal pain. It is more suitable for chronic inflammation or skin conditions.
Choice B rationale
Increasing fluid intake is beneficial for overall health, but it does not directly address acute perineal pain.
Choice C rationale
Catheterizing the bladder is not indicated for perineal pain unless there is a specific issue with urinary retention.
Choice D rationale
Offering an ice pack helps reduce swelling and numb the area, providing immediate relief for acute perineal pain. It is a standard intervention for postpartum perineal discomfort.
Correct Answer is D
Explanation
Choice A rationale
Amniotic fluid with meconium noted can indicate fetal distress, but it is not the most immediate priority compared to fetal heart tones.
Choice B rationale
A maternal temperature of 38.3°C (101°F) can indicate infection, but it is not the most immediate priority compared to fetal heart tones.
Choice C rationale
Foul-smelling vaginal discharge can indicate infection, but it is not the most immediate priority compared to fetal heart tones.
Choice D rationale
Fetal heart tones of 98/min indicate fetal bradycardia, which is a sign of fetal distress and requires immediate intervention to ensure the well-being of the fetus.
