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
Tingling in the fingers, also known as carpal tunnel syndrome, is more commonly associated with the later stages of pregnancy when fluid retention is more pronounced. It is not typically a common discomfort during the first trimester.
Choice B rationale
Round ligament pain is more common in the second trimester when the uterus is growing rapidly and the ligaments supporting it stretch. This type of pain usually manifests as sharp, shooting pain in the lower abdomen or groin.
Choice C rationale
Perineal discomfort and pressure are more common in the later stages of pregnancy, particularly in the third trimester, as the baby descends into the pelvis and prepares for birth. It is not typically a discomfort experienced during the first trimester.
Choice D rationale
Increased urgency and frequency of urination are common discomforts during the first trimester of pregnancy. This occurs due to hormonal changes and the growing uterus pressing on the bladder, which reduces its capacity.
Correct Answer is C
Explanation
Choice A rationale
Nursing the baby for 5 to 10 minutes on each breast may not be sufficient for the baby to receive the hindmilk, which is rich in fat and essential for growth.
Choice B rationale
Applying vitamin E oil to the nipples after each feeding is not recommended as it can cause irritation and is not necessary for nipple care.
Choice C rationale
Laying the baby on a pillow at the level of the breast helps ensure proper positioning and latch, which is crucial for effective breastfeeding and preventing nipple soreness.
Choice D rationale
Ensuring that just the nipple is in the baby’s mouth is incorrect. The baby should latch onto the areola, not just the nipple, to ensure effective milk transfer and prevent nipple pain.
