A newborn's lab result indicates a phenylketonuria (PKU) level of 30 mg/dl. What should the nurse do next?

Explanation

• A normal PKU is less than 2 mg/dl.

• A PKU level of 30 mg/dl is critically elevated and should be communicated to the physician immediately to provide early intervention.

• Phenylalanine is an amino acid normally present in the body. This test is done to check whether the baby has an enzyme needed to change phenylalanine into tyrosine. Without it, the phenylalanine level builds up in the body, causing brain damage, microcephaly, and cerebral impairment.

• Incorrect: The nurse should document the result, but only after the physician has been notified.
