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.

Correct Answer: A

Rationale: The priority nursing intervention for a child with acute lymphoblastic leukemia (ALL) receiving chemotherapy is to prevent infection. Chemotherapy compromises the child's immune system, increasing susceptibility to infections. Preventing infection is crucial to avoid potential complications such as sepsis, which can be life-threatening. Administering chemotherapy is essential for treating ALL but preventing infection takes precedence due to the increased risk of infections associated with chemotherapy-induced immunosuppression. Providing nutritional support is important for overall health but preventing infections is more critical in this context. Monitoring fluid intake is significant, but the priority is to prevent infections that can have severe consequences in an immunocompromised child.

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: Negativism in toddlers commonly occurs around the age of 2 as they begin to assert their independence and autonomy. At this stage, children are exploring their own will and preferences, leading to behaviors like defiance or negativism. Independence (choice D) is the primary need being met by this behavior as toddlers strive to establish their individuality and decision-making. While trust (choice A) is crucial for forming secure attachments, it is not the main need driving negativism in this case. Seeking attention (choice B) may be a behavior exhibited by children, but it is not the fundamental need being fulfilled by negativism. Discipline (choice C) is important for setting boundaries and teaching appropriate conduct, but it is not the primary need being addressed by negativism in toddlers.

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.
