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","C","D","E"]

Explanation

Choice A rationale:

Drying the baby thoroughly is not directly related to assessing the successful transition of the respiratory system. It is essential for warmth and comfort but does not provide specific information about the respiratory system.

Choice B rationale:

Suctioning the mouth and nose with a bulb syringe to clear mucus is important to ensure the airways are clear and the newborn can breathe effectively. This action helps assess the airway patency and successful initiation of breathing.

Choice C rationale:

Observing the chest and abdomen is crucial to assess the respiratory effort and symmetry. Normal chest movements and equal rise and fall of the abdomen indicate a successful transition of the respiratory system.

Choice D rationale:

Counting the number of respirations per minute is essential to determine if the respiratory rate falls within the expected reference range (around 30-60 breaths per minute for a newborn) and if there are any irregularities.

Choice E rationale:

Observing the color of the mucous membranes is important as cyanosis (blue discoloration) may indicate inadequate oxygenation. Pink mucous membranes are a positive sign, indicating a successful transition of the respiratory system.

A. Bilirubin 18 mg/dL. B. Hemoglobin 22 g/dL. C. Blood glucose 50 mg/dL. D. Platelets 200,000/mm³.

Correct Answer is A

Explanation

Choice A rationale:

This is the priority finding because a bilirubin level of 18 mg/dL in a 4-hour-old newborn is significantly elevated. High bilirubin levels in newborns can lead to jaundice, which can be harmful if not promptly addressed. Hyperbilirubinemia in newborns requires close monitoring and, in some cases, treatment with phototherapy.

Choice B rationale:

A hemoglobin level of 22 g/dL is within the normal range for a newborn and is not a priority concern at this time.

Choice C rationale:

A blood glucose level of 50 mg/dL is within the normal range for a newborn. While monitoring blood glucose levels is essential, it is not the priority in this situation.

Choice D rationale:

A platelet count of 200,000/mm³ is within the normal range for a newborn and does not require immediate action.
