The parents of a newborn with phenylketonuria (PKU) need help and support in adhering to specific dietary restrictions. They ask the nurse, "How long will our child have to be on this diet?" How should the nurse respond?

Correct Answer: D

Rationale: The correct answer is D: "This is a lifelong problem, and it is recommended that dietary restrictions must be continued." Phenylketonuria (PKU) is a metabolic disorder where the body cannot process phenylalanine properly. The diet for PKU must be continued lifelong to prevent cognitive and developmental issues, as phenylalanine buildup can cause irreversible damage. Choice A is incorrect because the nurse should provide information about the lifelong nature of the dietary restrictions for PKU. Choice B is incorrect as it suggests reintroducing protein-containing foods, which is not recommended for individuals with PKU. Choice C is incorrect as it underestimates the duration of the necessary dietary restrictions for PKU.

Correct Answer: A

Rationale: Friedman's structural functional theory outlines different functions of a family. The affective function, as defined by Friedman, pertains to meeting the love and belonging needs of each member. This includes emotional support, nurturing, and creating a sense of security within the family unit.

Rationale: Allowing the child to play with a favorite toy while taking the medication is the best approach to gain cooperation. This strategy can help distract and calm the child during the medication administration process. Choice A may not be as effective with a young child who may not fully understand the explanation. Offering a reward (choice C) may reinforce negative behavior and create a dependency on rewards for cooperation. Giving the medication with food (choice D) may not always be appropriate and may not address the cooperation aspect.

Correct Answer: D

Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload which can worsen their condition. Monitoring fluid intake and output helps prevent complications like congestive heart failure. Encouraging activity (Choice B) should be individualized based on the child's condition and tolerance, as excessive activity can strain the heart. Promoting a high-calorie diet (Choice C) is not typically recommended for children with congenital heart disease unless specifically indicated, as excessive weight gain can worsen their cardiac function. Maintaining oxygen therapy (Choice D) may be necessary in some cases, but monitoring fluid status is a more fundamental aspect of care for children with congenital heart disease.
