What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

  • A. Mental retardation occurs if PKU is untreated.
  • B. Testing for PKU is done immediately after birth.
  • C. Treatment for PKU includes lifelong dietary management.
  • D. PKU is transmitted as an autosomal recessive trait.
Correct Answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.
