The nurse notes that a newborn's white blood cell count (WBC) is 15,000. The nurse is aware that:.

This indicates a severe infection.

This is a normal WBC for a newborn.

This is a lab error.

You must call the doctor.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

A white blood cell count of 15,000 does not necessarily indicate a severe infection. In newborns, WBC counts are typically higher than in adults, and they gradually decrease over the first few days after birth. A value of 15,000 falls within the normal range for a newborn and is not indicative of a severe infection.

Choice B rationale:

A white blood cell count of 15,000 is considered a normal range for a newborn. Newborns have higher WBC counts as a natural response to the stress of birth and exposure to the outside environment. The immune system is still developing, and elevated WBC counts are normal during this period.

Choice C rationale:

Assuming there are no other indications of lab error, such as abnormal results in other tests, it would be premature to label the WBC count as a lab error. Additionally, healthcare professionals should always consider the overall clinical picture before assuming a lab error based on a single result.

Choice D rationale:

There is no immediate need to call the doctor based solely on the WBC count of 15,000. Medical decisions should be made in the context of the newborn's overall clinical condition, and a single lab result does not warrant an immediate call to the doctor.

Correct Answer is B

Explanation

A. Maintaining ambient room temperature at 24° C (75° F) can help prevent heat loss by keeping the environment warm, but it does not specifically address evaporative heat loss. Evaporative heat loss occurs when moisture on the skin evaporates, which is not directly controlled by ambient temperature.

B. Drying the newborn's skin thoroughly reduces evaporative heat loss by removing moisture that can evaporate and cool the skin. This action is critical immediately after birth when the newborn is wet with amniotic fluid.

C. Preventing air drafts helps reduce convective heat loss, not evaporative heat loss. Convective heat loss occurs when air moves across the skin and carries heat away.

D. Placing the newborn on a warm surface helps reduce conductive heat loss by preventing heat transfer from the baby to a cooler surface. However, this does not address evaporative heat loss, which is specifically related to moisture evaporation from the skin.

A. Iron will facilitate bone growth. B. Newborns do not metabolize iron adequately. C. The newborn's iron source will start to deplete. D. Iron will facilitate eyesight development.

Correct Answer is B

Explanation

Choice A rationale:

Iron will facilitate bone growth. This statement is not accurate in the context of feeding a newborn with iron-fortified formula. While iron is essential for overall growth and development, its primary role is not specifically related to bone growth. Instead, it plays a crucial role in the production of hemoglobin, which helps carry oxygen in the blood.

Choice B rationale:

Newborns do not metabolize iron adequately. This statement is the correct choice. Newborns have limited iron stores that are obtained from their mothers during pregnancy. As they grow, their iron requirements increase, but their ability to metabolize iron is not fully developed at

birth. Hence, iron-fortified formula is recommended to provide the necessary iron for the newborn's healthy development.

Choice C rationale:

The newborn's iron source will start to deplete. This statement is not accurate in the context of iron-fortified formula feeding. The newborn's initial iron source is the iron stores passed on by the mother during pregnancy. However, the iron-fortified formula is designed to supplement and fulfill the baby's iron needs, preventing depletion of iron stores.

Choice D rationale:

Iron will facilitate eyesight development. This statement is not entirely accurate. While iron is important for many bodily functions, including eye health, it is not specifically responsible for eyesight development in newborns. Visual development in newborns is influenced by various factors, but iron intake through formula feeding directly impacting eyesight is not a primary concern.
