C
Feedback:
The nurse should keep in mind that, if left untreated, phenylketonuria can result in mental impairment, behavioral problems, retardation, and other abnormalities. No cure exists for this condition, but it can be controlled with a special diet. The condition is not caused by any maternal infections. Phenylketonuria is a genetic defect that renders the newborn incapable of metabolizing certain amino acids, which spill into the blood and tissues in the form of phenylalanine.
