Exhibit 1. The names of the newborn reflexes are? Select all that apply.
rooting.
stepping.
moro.
Babinski.
Correct Answer : A,C,D,F
Choice A rationale:
The newborn reflex called "rooting”. is characterized by turning the head and opening the mouth when the cheek or mouth area is touched. This reflex helps the newborn find the mother's breast for feeding.
Choice B rationale:
"Stepping”. is a newborn reflex where they make stepping movements when held upright with their feet touching a solid surface. This reflex is present at birth but tends to disappear after a few weeks.
Choice C rationale:
The "Moro”. reflex is also known as the startle reflex. It is elicited by a sudden loss of support or loud noise, causing the newborn to throw their arms and legs out and then bring them back in. This reflex usually disappears around 3 to 4 months of age.
Choice D rationale:
The "Babinski”. reflex is characterized by the extension of the big toe and fanning of the other toes when the sole of the foot is stroked. This reflex is present in newborns and should disappear by around 12 months of age.
Choice E rationale:
"Running”. is not a recognized newborn reflex. There is no reflex with this name related to newborns.
Choice F rationale:
The "gag”. reflex is present in newborns and helps protect the airway by causing a gagging response when the back of the throat is stimulated.

Correct Answer is B
Explanation
Choice A rationale:
Providing a heat source for the newborn is not the purpose of surfactant. Surfactant is a substance produced in the lungs to reduce surface tension and prevent alveolar collapse during expiration. It helps with the exchange of gases, but it does not generate heat.
Choice B rationale:
This is the correct answer. Surfactant plays a crucial role in assisting the alveoli to remain open by reducing surface tension. This, in turn, allows for proper gas exchange, especially of oxygen and carbon dioxide.
Choice C rationale:
Assisting the ductus arteriosus to remain open is not the purpose of surfactant. The ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs. After birth, it should close on its own, and surfactant does not influence this process.
Choice D rationale:
Providing energy to the newborn is not the purpose of surfactant. Energy for the newborn comes from nutrition, particularly breast milk or formula, and not from surfactant
Correct Answer is C
Explanation
Choice A rationale:
(Incorrect) The newborn with significant bruising from a face presentation is at an increased risk of elevated unconjugated bilirubin levels. Bruising can lead to the breakdown of red blood cells, increasing bilirubin production.
Choice B rationale:
(Incorrect) The premature newborn is at a higher risk of elevated unconjugated bilirubin levels. Premature infants often have an underdeveloped liver, which can lead to reduced bilirubin processing and clearance.
Choice C rationale:
(Correct) The baby born at 41 weeks' gestation is at the lowest risk for elevated unconjugated bilirubin levels. By this stage, the baby's liver is more mature, allowing for efficient processing and clearance of bilirubin.
Choice D rationale:
(Incorrect) The newborn with O+ blood type, born to a mother with O- blood type, is at an increased risk of elevated unconjugated bilirubin levels if the baby's blood type is Rh-positive and the mother's is Rh-negative. This situation can lead to Rh incompatibility and hemolytic disease of the newborn, causing higher bilirubin levels.
