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.
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 C
Explanation
Choice A rationale:
Iron is crucial for the development of hemoglobin, which carries oxygen to all parts of the body, including the bones, but it does not directly facilitate bone growth.
Choice B rationale:
While newborns do metabolize iron, their iron stores are limited, and breast milk alone may not meet their iron needs.
Choice C rationale:
When educating a parent about the use of iron-fortified formula for their newborn, it is essential to convey that newborns have a limited store of iron, which begins to deplete around the age of 6 months.
Choice D rationale:
Iron facilitating eyesight development is not a relevant aspect to consider when discussing the use of iron-fortified formula for a newborn. While iron is essential for various physiological functions, it is not specifically linked to eyesight development.
Correct Answer is C
Explanation
Choice A rationale:
Wearing a supportive bra can actually help to manage engorgement, so it's not recommended to avoid wearing one during the day.
Choice B rationale:
Cold compresses are typically applied after feeding to reduce swelling, not before. Applying them before might hinder the milk let-down reflex.
Choice C rationale:
Frequent feeding can help to alleviate engorgement by ensuring that the breasts are being emptied regularly.
Choice D rationale:
Stopping breastfeeding until finishing antibiotics is not advisable, as it can lead to decreased milk supply and potential issues with engorgement. Antibiotics prescribed by a healthcare provider are usually safe to take while breastfeeding, and interrupting breastfeeding can exacerbate the engorgement problem. This choice is not appropriate for managing breast engorgement and is therefore incorrect.
