Pediatric HESI Practice Questions

Correct Answer: C

Rationale: The correct answer is C. Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially. Choice A is incorrect because a 6-week-old infant born without an immune system would not be able to limit exposure to pathogens effectively. Choice B is incorrect as antibodies produced by colonic bacteria are not a significant source of immunity in infants. Choice D is incorrect as the fetal thymus primarily plays a role in T cell development rather than antibody production during gestation.

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.

Correct Answer: D

Rationale: Poor wound healing is a common clinical manifestation of type 1 diabetes mellitus. High blood glucose levels in diabetes can impair the body's ability to heal wounds effectively. Choices A, B, and C are incorrect. Moist skin is not a typical clinical manifestation of type 1 diabetes; instead, skin may become dry due to dehydration. Weight gain is unlikely as type 1 diabetes is characterized by weight loss. Fluid overload is also uncommon in type 1 diabetes, which is more commonly associated with dehydration due to frequent urination.

Correct Answer: B

Rationale: Establishing a bedtime routine is the most appropriate suggestion for a child experiencing night terrors. Consistent bedtime routines help create a sense of security and predictability, reducing the likelihood of night terrors. Encouraging the child to talk about the dream (Choice A) may not be effective as night terrors occur during non-REM sleep, and the child may not remember the dreams. Allowing the child to sleep with the parents (Choice C) can reinforce dependency and may not address the underlying causes of night terrors. Waking the child during the night (Choice D) can disrupt their sleep cycle and worsen the occurrence of night terrors.

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.
