ATI Nur235 Pediatrics Final Exam Questions

Extract:

Newborn with phenylketonuria (PKU).


Question 1 of 5

The caregiver whose newborn was newly diagnosed with phenylketonuria (PKU) has questions about the disorder. Which statement made by the nurse is correct regarding PKU?

Correct Answer: B

Rationale: The correct answer is B: Severe cognitive deficits can result with untreated PKU. PKU is a genetic disorder where the body cannot process phenylalanine properly, leading to a buildup of harmful levels in the blood. This accumulation can cause severe cognitive impairments if left untreated, particularly in infants whose brains are still developing. Early diagnosis and treatment through a strict low-phenylalanine diet can prevent these cognitive deficits.

A: A urine test cannot adequately diagnose PKU as it requires a blood test to measure phenylalanine levels.
C: Phenyl pyruvic acid is not typically found in high concentrations in urine with PKU, but rather in the blood.
D: The effects of PKU are not reversible, but early intervention can prevent further cognitive damage.
