Correct Answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, the priority nursing intervention is administering pain medication to alleviate the severe pain associated with the crisis. While administering oxygen can help improve oxygenation, pain relief is crucial in managing the crisis. Monitoring fluid intake is important in sickle cell anemia but is not the most immediate intervention during a vaso-occlusive crisis. Encouraging physical activity is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and complications.

Correct Answer: C

Rationale: The correct preoperative intervention for a child with pyloric stenosis is to monitor for signs of dehydration. Pyloric stenosis can lead to vomiting, which can result in dehydration. Monitoring for signs of dehydration is crucial to ensure the child's fluid balance is maintained. Administering intravenous fluids, although important for managing dehydration and electrolyte imbalances, would typically be done postoperatively rather than as a preoperative intervention. Monitoring for signs of infection is important but not specific to the preoperative period for pyloric stenosis. Monitoring for signs of pain is also important but may not be the most critical preoperative intervention in this scenario.

Correct Answer: C

Rationale: The most appropriate response for the nurse is to emphasize the importance of consistency in discipline when dealing with toddlers. Toddlers are at an age where they are learning boundaries and acceptable behaviors. By being consistent, parents can help their child understand what is expected of them and establish a sense of structure and routine. Choices A, B, and D do not provide constructive advice or guidance on how to address the issue of disciplining a 2-year-old. Choice A merely acknowledges the age without providing guidance, choice B seeks more information without offering support, and choice D labels the age without offering practical advice on discipline.

Correct Answer: A

Rationale: The correct answer is A: 'They may occur in minor illnesses.' Febrile seizures can occur even in minor illnesses, particularly in young children, and are often triggered by a rapid increase in body temperature. Choice B is incorrect because the cause of febrile seizures is not always readily identified. Choice C is incorrect as febrile seizures commonly occur in children aged 6 months to 5 years, which includes the toddler years. Choice D is incorrect as febrile seizures are slightly more common in males than females.
