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 B
Explanation
Choice A reason:
If the client reports frequent uterine contractions , it is not indicative of a distended bladder. Postpartum uterine contractions are normal and necessary to help the uterus return to its pre-pregnancy size.
Choice B reason:
The fundus (the top portion of the uterus being palpable to the right of the midline suggests a distended bladder. A full bladder can displace the uterus, causing the fundus to deviate from the midline.
Choice C reason:
Having less than 2.5 cm of rubra lochia on a perineal pad is related to the amount of vaginal discharge after birth and does not provide information about bladder distention.
Choice D reason:
The client's report of increased thirst may indicate dehydration or the body's response to fluid loss during childbirth but is not directly related to bladder distention.
Correct Answer is C
Explanation
Choice A reason:
Occasional uterine cramping when the infant nurses is a normal phenomenon that occurs as the uterus contracts and returns to its pre-pregnancy size. This is not a sign of infection or complication and does not need to be reported.
Choice B reason:
Descent of the fundus one fingerbreadth each day is also a normal finding that indicates the uterus is involuting properly. The fundus is the top of the uterus that can be felt through the abdomen. It should be at the level of the umbilicus immediately after delivery and then descend about one fingerbreadth (or 1 cm) each day until it reaches the pelvic brim by 10 days postpartum.
Choice C reason:
Reappearance of red lochia after it changes to serous is an abnormal sign that may indicate uterine atony, subinvolution, or retained placental fragments. Lochia is the vaginal discharge that occurs after childbirth, consisting of blood, mucus, and tissue. It usually changes from red to pink to brown to yellow-white over a period of several weeks. If it becomes red again, it may mean that there is bleeding from the uterus or infection in the endometrium. This should be reported to a health care provider as soon as possible.
Choice D reason:
Oral temperature that is 37.2 C (99 F) in the morning is within the normal range and does not indicate fever or infection. A slight elevation in temperature may occur due to dehydration, breast engorgement, or hormonal changes. This does not need to be reported unless it exceeds 38 C (100.4 F) or persists for more than 24 hours.
