Pediatric HESI Practice Questions

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: D

Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing accounts for individual variations in drug metabolism and distribution, ensuring a more precise and safer medication administration. Choices A, B, and C are incorrect as they do not address the importance of weight-based dosing in children, potentially leading to inappropriate dosing and safety concerns.

Correct Answer: B

Rationale: The correct answer is B: 'Despair'. In separation anxiety, the stage of despair is characterized by regression and withdrawal after the initial protest. The toddler's shift from intense crying to lying quietly with a blanket demonstrates this withdrawal behavior. Choice A, 'Denial', is incorrect as denial involves refusing to accept the reality of separation. Choice C, 'Mistrust', is incorrect as it relates to a lack of trust rather than the stage of separation anxiety described in the scenario. Choice D, 'Rejection', is incorrect as it does not reflect the behavior of the toddler in the scenario, which is more indicative of withdrawal and regression.

Correct Answer: A

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.

Correct Answer: A

Rationale: After a prolonged hospitalization, a toddler may exhibit excessively demanding behavior as they readjust to being home. This behavior can be a result of the child seeking extra attention and reassurance after a stressful experience. Choices B, C, and D are incorrect because hostility, cheerfulness with shallow attachment, and withdrawal without emotional ties are less likely outcomes in this situation and do not align with common reactions of toddlers after hospitalization.
