Which of the following is an example of a primitive reflex that is present in newborns and typically disappears by 3-4 months of age?
Palmer grasp rettex
Babinski
Rooting reflex:
Moro reflex
The Correct Answer is D
A) Palmer grasp reflex:
The palmer grasp reflex is a primitive reflex in which a newborn will grasp an object placed in their hand. While this reflex is present at birth, it typically disappears by 5-6 months of age, not by 3-4 months. The Moro reflex, which is more related to startle and sudden movements, is the correct answer in this case.
B) Babinski reflex:
The Babinski reflex, in which the toes fan out when the sole of the foot is stroked, is present at birth but typically disappears by 12 months. This reflex is an indicator of neurological development, and its presence beyond the first year could suggest neurological concerns, but it is not the reflex in question here.
C) Rooting reflex:
The rooting reflex occurs when the newborn turns their head and opens their mouth in response to cheek stimulation, typically to find the nipple for breastfeeding. This reflex is present at birth and usually disappears by 3-4 months, which is similar to the timing mentioned in the question.
D) Moro reflex:
The Moro reflex is a startle reflex in which the infant spreads their arms and then pulls them back in when they feel a sudden loss of support or a loud noise. This reflex is present at birth and typically disappears by 3-4 months of age. It is considered a classic primitive reflex that fades as the infant's nervous system matures.

Correct Answer is C
Explanation
A) Dry and stimulate newborn with towel:
Drying and stimulating the newborn immediately after birth is a standard practice to prevent heat loss and promote early bonding. This action helps to prevent heat loss through evaporation and stimulates the newborn to breathe. It is an appropriate intervention to reduce the risk of hypothermia, not increase it.
B) Place a hat on the newborn's head:
Placing a hat on the newborn’s head is an appropriate and helpful intervention. Since a significant amount of heat is lost through the head, especially in newborns who have a larger surface area relative to their body mass, keeping the head covered with a hat helps to retain warmth and reduce the risk of hypothermia. This would not place the newborn at risk for hypothermia.
C) Maintain the delivery room temperature at 20° C (68° F):
A delivery room temperature of 20° C (68° F) is on the lower end of the recommended range for newborn care. Newborns are particularly susceptible to heat loss due to their high surface area-to-body weight ratio and immature thermoregulation system. A cooler environment like 20°C increases the risk of hypothermia, as the newborn will lose heat more quickly than it can generate on its own.
D) Place a blanket on top of maternal and newborn:
Placing a blanket over the mother and newborn is an appropriate intervention to prevent heat loss. This promotes warmth by reducing heat loss from the newborn's body surface to the cooler environment. This would not place the newborn at risk for hypothermia; instead, it helps to maintain body temperature.
Correct Answer is ["A","B"]
Explanation
A) Ask the client to empty their bladder:
One of the first actions the nurse should take when the uterus is not firm (often referred to as uterine atony) is to ask the client to empty their bladder. A full bladder can interfere with uterine contraction and cause the uterus to be boggy or soft, which can lead to postpartum hemorrhage. Encouraging the client to void may help the uterus contract more effectively and reduce the risk of complications.
B) Perform fundal massage:
If the uterus is not firm, performing a fundal massage is essential. Fundal massage helps stimulate uterine contractions and helps the uterus contract to its normal size, reducing the risk of bleeding. It is a critical intervention in postpartum care to ensure that the uterus remains firm and does not become atonic, which can cause excessive blood loss.
C) Nothing, this is an expected finding:
A soft uterus (uterine atony) is not an expected finding 4 hours postpartum. A firm uterus is expected at this point to prevent hemorrhage. The nurse should take immediate action to address the issue of uterine atony, as failure to do so can lead to significant postpartum hemorrhage, a life-threatening complication.
D) Ambulate the client in the hallway:
Ambulation may be helpful later in the postpartum period to encourage circulation and prevent thromboembolism, but it is not a priority when the uterus is not firm. The first priority is to address uterine atony, and actions like emptying the bladder and massaging the fundus should be performed before ambulating the client.
E) Give pain medications:
While pain management is important, it is not the priority intervention when the uterus is not firm. The nurse must first address the cause of uterine atony (such as bladder distention) and stimulate uterine contractions via fundal massage to ensure that the uterus is firm and the client is not at risk for excessive bleeding. Pain medications can be given once the immediate uterine concerns have been addressed.
