HESI Pediatrics Quizlet

Correct Answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.

Correct Answer: D

Rationale: When caring for a child with acute laryngotracheobronchitis, the priority action should be to continually assess the respiratory status. This is crucial to detect early signs of respiratory distress, such as worsening stridor or increased work of breathing. Prompt intervention can prevent further deterioration of the child's condition. Initiating measures to reduce fever (Choice A) may be necessary but is not the priority in this situation. Ensuring delivery of humidified oxygen (Choice B) is important for maintaining oxygenation but should follow the assessment of respiratory status. Providing support to reduce apprehension (Choice C) is also important for the child's comfort but is not the priority over assessing and managing respiratory distress.

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 clinical manifestation the healthcare provider is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception involves one portion of the intestine telescoping into another, causing obstruction. Abdominal distension is a common symptom due to the obstruction and buildup of gas and fluid in the affected area. While projectile vomiting can occur, it is not as specific to intussusception as abdominal distension. Currant jelly stools, which are stools containing blood and mucus, are a classic sign of intussusception but are not a clinical manifestation observable on assessment. Constipation is not typically associated with intussusception, as this condition often presents with symptoms of bowel obstruction rather than constipation.

Correct Answer: D

Rationale: Teaching seizure first aid to family members is crucial in ensuring the child's safety during a seizure. This education empowers family members to respond effectively, protect the child from injury, and provide appropriate care. Option A is incorrect because antiepileptic medication should be administered as prescribed, not only when a seizure occurs. Option B, while important for overall health, is not specific to managing seizures. Option C is incorrect as there is no evidence that restricting activities prevents seizures, and it may negatively impact the child's quality of life without offering additional safety benefits.
