Correct Answer: C

Rationale: Seizures in children most often result from a temperature greater than 102°F, known as febrile seizures. Febrile seizures are commonly triggered by a rapid increase in body temperature due to infections or other causes. Choice A is incorrect as febrile seizures are not necessarily caused by the abrupt rise in body temperature alone. Choice B is incorrect as inflammatory processes in the brain may lead to other types of seizures but are not the most common cause in children. Choice D is incorrect as not all seizures in children are due to life-threatening infections.

Correct Answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

Correct Answer: B

Rationale: By 11 months of age, the recommended vaccines for infants include diphtheria, pertussis, tetanus, and polio. These vaccines are part of the routine immunization schedule to protect infants from serious infectious diseases. Choice A is incorrect because measles is not typically administered at this age. Choice C is incorrect because rubella and tuberculosis are not part of routine infant immunizations. Choice D is incorrect because measles, mumps, and rubella are usually given as a combination vaccine later in childhood, not at 11 months of age.

Correct Answer: A

Rationale: The correct answer is to maintain a structured routine. Children with autism spectrum disorder benefit greatly from structured routines as they provide a sense of stability and predictability, which can help reduce anxiety and improve behavior. Encouraging social interaction (Choice B) is important but may need to be approached in a structured manner to prevent overwhelming the child. Positive reinforcement (Choice C) is also beneficial for behavior management but may not address the overall need for routine and predictability that is crucial for children with autism. Using a communication board (Choice D) may be helpful for facilitating communication, but establishing and maintaining a structured routine is fundamental for supporting the child's development and well-being in managing their autism spectrum disorder.

Correct Answer: C

Rationale: In this scenario, the nurse should notify Child Protective Services for immediate intervention. The girl disclosed ongoing sexual abuse by her grandfather, which is a serious concern requiring immediate protection and intervention by the appropriate authorities. Child Protective Services are trained to handle cases of child abuse and neglect, ensuring the safety and well-being of the child. While notifying the police about a possible sex crime is crucial, Child Protective Services should be the first point of contact in cases of suspected child abuse due to their specialized role. Confirming the pregnancy through a healthcare provider is not the priority at this moment, as ensuring the safety of the child is paramount. Informing the girl's mother about the positive test result is not appropriate given the lack of belief in the abuse disclosure and the potential risk to the child's safety.
