A nurse is reviewing a newborn's laboratory results. Which of the following findings is the nurse's priority?

A.

Platelets 200,000/mm3

B.

Bilirubin 19 mg/dL

C.

Blood glucose 45 mg/dL

D.

Hemoglobin 22 g/dL

Answer and Explanation

The Correct Answer is B

   - A) A platelet count of 200,000/mm3 is within the normal range for a newborn and does not require immediate intervention.
    - B) A bilirubin level of 19 mg/dL is high and suggests the possibility of hyperbilirubinemia, which can lead to jaundice and, in severe cases, kernicterus, a form of brain damage. This is a critical value that requires immediate attention.
    - C) A blood glucose level of 45 mg/dL is on the lower end of the normal range, but it is not as immediately concerning as the elevated bilirubin level. Monitoring and appropriate feeding should address this issue.
    - D) A hemoglobin level of 22 g/dL is high, indicating polycythemia, which can be a risk factor for hyperviscosity syndrome. However, it is not as urgent as the bilirubin level of 19 mg/dL. Monitoring and partial exchange transfusion may be considered if symptoms develop.

Correct Answer is D

Explanation

A. Administering thyroid hormone replacement is not indicated for phenylketonuria (PKU). PKU is a metabolic disorder involving the inability to metabolize phenylalanine, an amino acid, and it does not involve thyroid dysfunction.
B. Blood glucose monitoring is not directly related to the management of PKU. In PKU, the focus is on monitoring and restricting phenylalanine intake, not blood glucose levels.
C. Obtaining a blood sample for blood type may be necessary for general newborn screening but is not specific to the management of PKU.
D. Initiating a controlled low-protein diet is the cornerstone of management for PKU. This diet restricts phenylalanine intake, which is essential for preventing neurological damage and
developmental delays in affected infants.
