A nurse is reinforcing teaching about preterm labor with a client who is at 28 weeks of gestation.Which of the following statements by the client indicates an understanding of the teaching?
“I should expect to feel pain in my upper right abdomen if I’m having preterm labor.”.
“If I have contractions more often than every 10 minutes, I might be in preterm labor.”.
“I can take a daily iron supplement to prevent preterm labor.”.
“I might be experiencing preterm labor if walking stops my contractions.”.
The Correct Answer is B
Choice A rationale
Pain in the upper right abdomen is not a typical sign of preterm labor. Preterm labor symptoms include regular contractions, lower back pain, and pelvic pressure.
Choice B rationale
Contractions occurring more frequently than every 10 minutes can indicate preterm labor. Regular contractions are a key sign of preterm labor.
Choice C rationale
While iron supplements are important during pregnancy, they do not prevent preterm labor. Preterm labor is influenced by various factors, including infections and uterine abnormalities.
Choice D rationale
Walking typically does not stop contractions associated with preterm labor. In fact, activity can sometimes exacerbate contractions.

Correct Answer is A
Explanation
Choice A rationale
A positive Babinski reflex is characterized by the fanning out of the toes and the upward movement of the big toe when the sole of the foot is stroked. This reflex is normal in infants up to 2 years old and indicates an immature central nervous system. The presence of this reflex in older children or adults can indicate neurological issues.
Choice B rationale
Curling in of the toes when the sole of the foot is stroked is indicative of the plantar grasp reflex, not the Babinski reflex. The plantar grasp reflex is a different neurological response and does not indicate the same neurological development as the Babinski reflex.
Choice C rationale
No response when the sole of the foot is stroked could indicate a lack of neurological response or an issue with the sensory or motor pathways. This is not characteristic of a positive Babinski reflex and could be a sign of neurological impairment.
Choice D rationale
The big toe bending down when the sole of the foot is stroked is a normal response in older children and adults, known as the plantar reflex. This response indicates a mature central nervous system and is not characteristic of a positive Babinski reflex in infants.
Correct Answer is B
Explanation
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.
