Which assessment finding would cause the nurse to question whether a preschool-age boy, diagnosed with phenylketonuria shortly after birth, is following the prescribed dietary restrictions?
1. The child's body has a musty odor.
2. This child is a blue-eyed blond.
3. The child appears sleepy and uninterested in the surroundings.
4. The child has a sunburn over his entire body.

Explanation:
1. The odor is caused by the excretion of phenylketone by-products through the skin and would indicate noncompliance with the dietary restrictions.
2. While this is a characteristic of most children with PKU, it is not related to dietary intake or restrictions.
3. This is not a symptom of untreated phenylketonuria.
4. Photophobia is not associated with PKU. The child with untreated PKU has an eczematous rash.
