Pediatric HESI Practice Questions

Correct Answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines (MMR vaccine for measles, mumps, and rubella). Therefore, the correct answer is chickenpox (varicella). It is crucial for healthcare professionals to provide accurate information about vaccines to help ensure the health and well-being of individuals.

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 can be localized or spread, similar to adult cancers. Choice C is incorrect because childhood cancers can be highly responsive to treatment, especially when diagnosed early. Choice D is incorrect because the majority of childhood cancers cannot be prevented as they are often due to genetic mutations or unknown causes.

Correct Answer: C

Rationale: The correct answer is to advise the parent to call the poison control center. When a child ingests household bleach, it is important to seek guidance from professionals who can provide specific and immediate advice on managing the situation. Administering activated charcoal (Choice A) is not recommended for household bleach ingestion. Inducing vomiting immediately (Choice B) can lead to further complications and is not the recommended first response. Taking the child to the emergency department (Choice D) should be done based on the advice received from the poison control center.

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 monitoring fluid and electrolyte balance. Gastroenteritis is characterized by inflammation of the gastrointestinal tract, leading to fluid loss. Maintaining fluid and electrolyte balance is essential in managing gastroenteritis to prevent dehydration and electrolyte imbalances. Encouraging regular exercise (Choice B) is not a priority in the acute phase of gastroenteritis when the focus is on rehydration and symptom management. Administering antipyretics (Choice C) may be considered for fever management but is not the priority over monitoring fluid and electrolyte balance. Administering antibiotics (Choice D) is not routinely indicated for viral gastroenteritis, which is a common cause of the condition in children.
