HESI Pediatrics Quizlet

Correct Answer: A

Rationale: Seizures in children most often result from an abrupt rise in body temperature, leading to febrile seizures. Febrile seizures are common in young children and are typically triggered by a rapid increase in body temperature, often due to infections or other causes. An inflammatory process in the brain (Choice B) is less common as a cause of seizures in children and is usually associated with specific conditions like encephalitis or meningitis. While a temperature greater than 102�F (Choice C) may trigger a febrile seizure, it is the abrupt rise in temperature that is the primary cause. Choice D, a life-threatening infection, is a broad and less specific cause compared to the direct trigger of an abrupt rise in body temperature.

Correct Answer: B

Rationale: The correct answer is B: High fever. In bacterial meningitis, a high fever is a common clinical manifestation due to the body's inflammatory response to the infection. While photophobia (choice A) is also a common symptom in meningitis, it is not as specific as a high fever. Rash (choice C) is more commonly associated with viral infections or other conditions, rather than bacterial meningitis. Nasal congestion (choice D) is not a typical clinical manifestation of bacterial meningitis and is more commonly seen in respiratory infections. Therefore, when assessing a child with suspected bacterial meningitis, the nurse is most likely to observe a high fever as a key clinical manifestation.

Correct Answer: D

Rationale: The most common treatment for Hirschsprung disease is the surgical removal of the affected section of the bowel. This procedure entails excising the part of the colon that lacks nerve cells crucial for normal bowel function. Daily enemas (Choice A) can offer temporary relief for constipation but do not address the root cause of the condition, which is the absence of nerve cells. A low-fiber diet (Choice B) is not a primary therapy for Hirschsprung disease and may not effectively manage the disorder. A permanent colostomy (Choice C) is typically considered in severe cases where other interventions have failed and is not the standard management approach for Hirschsprung disease.

Correct Answer: C

Rationale: Longer periods of sleep than usual can be a sign of illness in infants. When an infant sleeps more than usual, it may indicate that the baby is conserving energy due to an underlying condition. Grunting respirations (choice A) can be a sign of respiratory distress, excessive perspiration (choice B) may indicate overheating or fever, and crying immediately after feedings (choice D) can be a sign of gastrointestinal discomfort, such as colic or reflux. However, in this scenario, the emphasis is on changes in sleep patterns as a potential indicator of illness.

Correct Answer: A

Rationale: The correct intervention for a sprained ankle is to apply ice for 20 minutes every hour for the first 24 hours, then remove for 60 minutes to prevent tissue damage. This regimen helps reduce swelling and pain. Bed rest with the leg elevated for an extended period (36 hours) may lead to stiffness and decreased range of motion. While NSAIDs can be used for pain, they may not be necessary if pain is manageable with ice and rest. Using a compression dressing for 72 hours continuously may impede proper circulation and delay healing by restricting blood flow.
