Which newborn reflex elicits the following reaction: Head turns to one side - the way the head is facing, the arm/leg is stretched out while the other is bent?
Tonic neck reflex.
Moro reflex.
Startled reflex.
Babinski reflex.
The Correct Answer is A
Choice A reason:
The tonic neck reflex, also called the fencing posture, occurs when a baby's head is turned to one side. The arm and leg on that side stretch out, while the opposite arm and leg bend up at the elbow. This reflex lasts until the baby is about 5 to 7 months old. This reflex matches the description of the question.
Choice B reason:
The Moro reflex, also called the startle reflex, is the baby's reaction to being startled. The cause is often a loud sound, a sudden movement, or even their own cry. As an adult, you may jump or gasp when you are startled. A baby will throw back their head, extend their arms and legs, cry, then pull their arms and legs back in. This reflex does not match the description of the question.
Choice C reason:
The startled reflex is not a distinct reflex in newborns. It is another name for the Moro reflex, which is explained.

Correct Answer is A
Explanation
Choice A reason:
Babinski's Reflex is the normal response in infants when the sole of the foot is stroked from the heel to the ball of the foot. The big toe moves upward or toward the top surface of the foot, and the other toes fan out. This reflex is normal in children up to 2 years old, and it disappears as the nervous system matures. It may indicate damage to the central nervous system in older children and adults.
Choice B reason:
Stepping Reflex is the normal response in infants when they are held upright with their feet touching a flat surface. They will lift one foot and then the other, as if they are walking. This reflex is present at birth and lasts for about 2 months. It helps prepare the infant for voluntary walking.
Choice C reason:
Moro Reflex is the normal response in infants when they are startled by a loud noise or a sudden movement. They will extend their arms and legs, open their hands, and then curl up and bring their arms together as if they are hugging themselves. This reflex is present at birth and lasts for about 4 to 6 months. It is thought to be a protective response that helps the infant cling to their caregiver.
Choice D reason:
Plantar Grasp Reflex is the normal response in infants when pressure is applied to the sole of the foot near the toes. The toes will curl down and grasp the stimulus. This reflex is present at birth and lasts for about 9 to 12 months. It is similar to the palmar grasp reflex in the hands, and it helps develop the muscles and nerves in the feet.

Correct Answer is B
Explanation
Choice A reason:
Lochial color changes from rubra to alba in the early postpartum period is a normal event. Lochia is the vaginal discharge that occurs after childbirth, and it progresses from bright red (rubra) to pink or brownish (serosa) to whitish-yellow (alba) as the days pass.
Choice B reason:
Extreme hunger and thirst in the early postpartum period may indicate abnormal blood sugar levels and can be a sign of gestational diabetes or other metabolic disorders. It requires further evaluation and monitoring by healthcare providers.
Choice C reason:
Diuresis (increased urination) and diaphoresis (increased sweating) are normal events in the early postpartum period. After childbirth, the body eliminates excess fluid that was retained during pregnancy, leading to increased urination and sweating.
Choice D reason:
Flatulence (passing gas) and constipation can be normal events in the early postpartum period due to the body recovering from the effects of labor, changes in diet, and the use of pain medications during childbirth.
