A nurse is caring for several newborn clients. For which of the following findings should the nurse notify the charge nurse?
A. A blood glucose fingerstick of 40 mg/dL for an infant who is 1-hr old.
A. A blood glucose fingerstick of 40 mg/dL for an infant who is 1-hr old: A blood glucose level of 40 mg/dL is borderline low but expected in the immediate postnatal period, especially if the infant is asymptomatic. Feeding the infant is the first step to address this, and monitoring is usually sufficient unless symptoms of hypoglycemia develop.
B. A hematocrit of 60% in an infant who is 8-hr old.
B. A hematocrit of 60% in an infant who is 8-hr old: This value is at the upper end of normal for a newborn and may suggest mild polycythemia. However, it does not require urgent notification unless accompanied by symptoms such as respiratory distress or poor perfusion
C. Jaundice in an infant who is 4-hr old.
C. Jaundice in an infant who is 4-hr old: Early-onset jaundice (within the first 24 hours) is not normal and suggests a potentially dangerous underlying condition, such as hemolytic disease of the newborn or infection. Immediate reporting and further evaluation, including bilirubin levels and possible treatment with phototherapy, are essential.
D. Acrocyanosis in an infant who is 2-hr old.
D. Acrocyanosis in an infant who is 2-hr old: Acrocyanosis (bluish discoloration of the hands and feet) is a common and benign finding in the first 24 to 48 hours after birth due to immature circulation. It does not require notification or intervention.

Similar Questions
Exhibit 1. The names of the newborn reflexes are? Select all that apply.
A. rooting.
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.
B. stepping.
"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.
C. moro.
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.
D. Babinski.
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.
A newborn is most interested in eating in which wake and sleep state?
A. crying.
Newborns do not show interest in eating while crying. Crying is usually an indication of distress or hunger and not a state where they are interested in eating.
B. alert.
Newborns are most interested in eating when they are in an "alert”. state. During this state, the baby is awake, calm, and attentive, making it an ideal time for feeding.
C. drowsy.
In the "drowsy”. state, newborns may be sleepy and less interested in eating. They might feed less effectively in this state.
D. active alert.
"Active alert”. is a state where the newborn is awake, attentive, and active. While they may be interested in their surroundings, they may also be easily distracted during feeding.

A nurse is caring for a newborn who is at 34 weeks of gestation, weighs 1,550 g, and has nasal flaring, intercostal retractions, expiratory grunting, and mild cyanosis. The nurse should place the newborn in an incubator for which of the following reasons?
A. The newborn's temperature control mechanism is immature.
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).
B. Heat increases the flow of oxygen to the newborn's extremities.
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.
C. The newborn has a small body surface for his weight.
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.
D. Heat facilitates the drainage of mucus for a premature newborn.
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.
