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 helps ensure that the child receives the appropriate amount of medication for their body size, which is crucial for safety and effectiveness. Age-based dosing can lead to underdosing or overdosing, as children of the same age can have significantly different weights. Choice A is incorrect because even small variations in dosages can have significant effects on a child's health. Choice B is incorrect as acetaminophen can be appropriate when used correctly for fever management in children. Choice C is incorrect as children's weights can vary greatly within the same age group, making weight-based dosing more precise and individualized.

Correct Answer: A

Rationale: The correct answer is A: Incisors. In infants, incisors are usually the first teeth to erupt, typically around 6 months of age. These are the front teeth used for cutting food. Canines (Choice B), upper molars (Choice C), and lower molars (Choice D) typically erupt after the incisors. Canines are sharp teeth used for tearing food, while molars are flat teeth used for grinding food.

Correct Answer: C

Rationale: In the case of a child ingesting household bleach, the primary advice should be to call the poison control center (Choice C). The poison control center can provide specific guidance on how to manage the ingestion, including whether any immediate interventions are necessary. Administering activated charcoal (Choice A) or inducing vomiting immediately (Choice B) can worsen the situation as they are not recommended treatments for bleach ingestion. Taking the child to the emergency department (Choice D) may be necessary depending on the advice given by the poison control center, but the initial step should be to seek guidance from the experts at the poison control center.

Correct Answer: A

Rationale: The correct answer is A. Most childhood cancers, such as leukemias and sarcomas, affect tissues rather than specific organs, unlike many adult cancers. Choice B is incorrect because childhood cancers may not always be localized when found. Choice C is incorrect as childhood cancers can be responsive to treatment, although treatment approaches may differ from adult cancers. Choice D is incorrect as the majority of childhood cancers cannot be prevented; however, certain risk factors can be managed to reduce the risk of developing cancer.
