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 A
Explanation
Choice A rationale:
Placing the newborn in an incubator is essential because the newborn's temperature control mechanism is immature. Premature infants have an underdeveloped thermoregulatory system, making them susceptible to heat loss and cold stress. An incubator provides a controlled, warm environment to maintain the newborn's body temperature within the normal range (around 36.5°C to 37.5°C or 97.7°F to 99.5°F).
Choice B rationale:
Heat increasing the flow of oxygen to the newborn's extremities is not a valid reason for placing the newborn in an incubator. Oxygenation is primarily influenced by respiratory and circulatory mechanisms, not external heat.
Choice C rationale:
The newborn's small body surface area for his weight is not directly related to the need for an incubator. Premature infants have a higher surface area to weight ratio, making them more prone to heat loss, but this is not the primary reason for using an incubator.
Choice D rationale:
Heat facilitating the drainage of mucus is not a reason for placing the newborn in an incubator. Proper positioning and suctioning are used to manage mucus in premature infants, but incubators are primarily for temperature regulation.
Correct Answer is B
Explanation
The nurse should use the lower ribcage border to measure chest circumference.
Choice A rationale:
The sternal notch is not an appropriate landmark for measuring chest circumference. It is a notch at the top of the sternum and not indicative of chest circumference.
Choice B rationale:
When measuring the chest circumference of a newborn, the correct anatomical landmark to use is the nipple line. This method ensures that the measurement is taken at a consistent and reproducible location across different individuals, providing an accurate assessment of the chest size relative to growth and development standards. It's important to position the measuring tape at the level of the nipples, encircling the chest at its largest point, which typically aligns with the nipple line.
Choice C rationale:
The lower ribcage border is also not suitable as it may vary significantly with respiratory movements and is not a stable landmark for consistent measurements.
Choice D rationale:
The axillae (armpits) are not used as a landmark for measuring chest circumference. It is not a standardized anatomical point for this purpose.
