HESI Pediatrics Quizlet

Correct Answer: A

Rationale: The correct answer is A. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It results in the production of thick, sticky mucus that can clog the lungs and obstruct the pancreas. This explanation is crucial for parents to understand the impact of the condition on their child's health. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but it requires a comprehensive management approach beyond just medication. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but rather by inheriting specific genetic mutations.

Correct Answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers. Lead exposure can lead to behavioral changes, including irritability, which is crucial for parents to recognize. While abdominal pain and constipation can occur in lead poisoning, they are not as specific or prominent as irritability. Frequent urination is not typically associated with lead poisoning in toddlers, making it a less relevant symptom to emphasize. By highlighting irritability, parents can be better equipped to identify potential signs of lead poisoning in their toddler.

Correct Answer: D

Rationale: The correct answer is D: surgical removal of the affected section of bowel. Hirschsprung disease is characterized by a segment of the colon lacking nerve cells, leading to obstruction. The definitive treatment involves surgically removing the affected segment, followed by a pull-through procedure to restore normal bowel continuity. Daily enemas (choice A) are not the primary treatment for Hirschsprung disease. While dietary adjustments may be advised, a low-fiber diet (choice B) alone is not curative for this condition. A permanent colostomy (choice C) is considered a last resort if surgical interventions fail or in severe cases, but it is not the initial therapeutic approach for managing Hirschsprung disease.

Correct Answer: A

Rationale: The correct answer is giving a pacifier to the newborn. Sucking is a natural reflex and a source of comfort for newborns, especially postoperatively. Offering a pacifier can help meet their developmental needs by providing comfort and a soothing mechanism. Placing a mobile over the crib (choice B) may provide visual stimulation but does not directly address the newborn's developmental needs for comfort and self-soothing. Providing a soft, cuddly toy (choice C) may offer some comfort but may not be as effective in meeting the specific developmental need for sucking postoperatively. Warming the newborn's formula before feeding (choice D) relates more to feeding practices than directly addressing a major developmental need in the postoperative period.

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.
