When a child with a diagnosis of asthma is prescribed a peak flow meter, what should the nurse teach the child and parents about using this device?

Correct Answer: C

Rationale: The correct answer is to record the best of three attempts when using a peak flow meter. This method provides a more accurate measure of peak expiratory flow. Choice A is incorrect because using the device before taking medication may not reflect the actual peak flow, as medication can affect lung function. Choice B is incorrect as using the device during asthma attacks may not be feasible or safe, as the focus during an attack should be on managing symptoms rather than measuring peak flow. Choice D is incorrect because using the device after eating may not provide an accurate measurement of peak flow, as digestion can affect lung function temporarily.

Correct Answer: B

Rationale: Peeling skin on the hands and feet is a characteristic clinical manifestation of Kawasaki disease, known as desquamation. This occurs during the convalescent phase of the illness, typically around 2-3 weeks after the onset of symptoms. While a generalized rash can be present in Kawasaki disease, peeling skin on the hands and feet is a more specific and distinctive feature. High fever is also a common symptom of Kawasaki disease, usually lasting for at least 5 days, while a low-grade fever is not typically associated with this condition. Therefore, the nurse is more likely to observe peeling skin on the hands and feet in a child suspected of having Kawasaki disease, making option B the correct choice.

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: A

Rationale: Monitoring liver function tests regularly is crucial when a child with JIA is on methotrexate due to the potential hepatotoxicity associated with this medication. Methotrexate can lead to liver damage, hence monitoring helps in early detection and intervention. Encouraging regular exercise (Choice B) is generally good for children with JIA to maintain joint mobility and muscle strength, but it is not directly related to methotrexate therapy. Providing high-calorie snacks (Choice C) is not a priority consideration for a child on methotrexate. Encouraging frequent handwashing (Choice D) is important for infection control, but it is not specifically associated with methotrexate therapy in a child with JIA.

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.
