HESI Pediatrics Quizlet

Correct Answer: A

Rationale: Right lower quadrant pain is a characteristic clinical manifestation of appendicitis. The appendix is typically located in the right lower quadrant of the abdomen, so pain in this area is a common symptom. Left lower quadrant pain (Choice B) is less likely in cases of appendicitis. Rebound tenderness (Choice C) is a sign of peritonitis, not specific to appendicitis. Epigastric pain (Choice D) is more indicative of upper gastrointestinal issues rather than appendicitis.

Correct Answer: D

Rationale: Mouth breathing due to a cleft lip can dry the mucous membranes, increasing their susceptibility to infection. While waste product accumulation (Choice A) and inadequate circulation (Choice B) may contribute to complications, they are not directly related to infection in this context. Inadequate nutrition (Choice C) may affect overall health but is not the primary reason for infection predisposition in this case.

Correct Answer: D

Rationale: The correct answer is to teach seizure first aid to family members. This is crucial because family members need to know how to appropriately respond during a seizure to ensure the child's safety. Choice A has been corrected to emphasize that antiepileptic medication should be administered as prescribed, not just when a seizure occurs, to effectively manage the condition. Choice B, while important for overall health, is not directly related to seizure management. Choice C is not recommended as restricting activities may not prevent seizures and may hinder the child's quality of life.

Correct Answer: C

Rationale: The correct statement is that infants may have difficulty balancing glucose and electrolytes because their endocrine systems are immature. Newborns have developing endocrine glands that are not yet fully functional, leading to challenges in maintaining glucose and electrolyte balance. Choice A is incorrect as endocrine glands start developing in the first trimester, not the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth. Choice D is incorrect because while a child's endocrine system indeed plays a vital role in growth and development, the specific focus of the question is on the challenges infants face due to immature endocrine glands.

Correct Answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.
