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
A. This condition typically results from excessive loss of acid, often due to vomiting or diuretics. It is not the most likely concern in a cold environment with an infant who has been crying and kicking.
B. A cold environment can lead to nonshivering thermogenesis in newborns, where they metabolize brown fat to generate heat. This process can lead to increased lactic acid production, potentially causing metabolic acidosis. The infant's fatigue following crying and kicking may indicate that the body has expended significant energy to stay warm, making metabolic acidosis a priority concern.
C. While hunger could be a reason for crying, it is not the priority concern in this scenario where environmental cold and fatigue are present.
D. Overstimulation might cause crying, but the environmental cold and subsequent risk of metabolic acidosis are more critical concerns in this context.
Correct Answer is D
Explanation
Choice A rationale:
"He is just cold”. is not the correct choice. While newborns can have cold hands and feet due to their immature thermoregulation, it would not explain persistent blue hands.
Choice B rationale:
"He may have been born with a heart problem”. is not the correct choice as it suggests a congenital heart defect. While cyanosis (bluish discoloration) can be associated with some heart problems, the hands alone being blue is less likely to be solely related to a heart issue.
Choice C rationale:
"The hands are always blue in a newborn”. is not the correct choice. While newborns may have bluish extremities (acrocyanosis) during the first few days after birth due to their developing circulatory system, persistent blue hands beyond this period would require further assessment.
Choice D rationale:
The correct choice is that "The circulation in his hands is not fully developed.”. Newborns have a developing circulatory system, and sometimes, their peripheral circulation takes some time to mature, leading to transient blue hands. However, if the blue color persists or worsens, it's essential to evaluate for any underlying issues.
