Correct Answer: D

Rationale: Asking the parents if they smoke in the home is the most relevant question as exposure to secondhand smoke can exacerbate respiratory symptoms like wheezing and difficulty breathing in children. This information is crucial for identifying potential triggers for the child's symptoms. Inquiring about child safety in the home, asking about the child's temperament, and inquiring about the child's diet, while important aspects of care, may not directly address the respiratory symptoms the child is experiencing.

Correct Answer: B

Rationale: When managing a child with partial thickness burns over the upper body areas, the priority action during the primary survey is to assess for a patent airway. This step is crucial as burns in this region can lead to airway compromise, potentially causing rapid deterioration in the child's condition. Checking for a patent airway ensures that the child can breathe adequately, which is essential for oxygenation and ventilation. Inspecting the child's skin color (Choice A) is an important assessment but should follow ensuring a patent airway. Observing for symmetric breathing (Choice C) is relevant, but the immediate focus should be on securing the airway. Palpating the child's pulse (Choice D) is also a vital assessment, but in this scenario, the priority is to assess and maintain a clear airway to support respiratory function and oxygen delivery.

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: D

Rationale: Left-to-right shunting in a cardiac malformation results in increased blood flow to the lungs. This increased blood flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a characteristic directly associated with left-to-right shunting. Severe growth retardation (Choice B) is not a typical manifestation of this type of congenital disorder. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions like chronic respiratory or cardiac diseases, not specifically with left-to-right shunting and associated cardiac malformations.

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. A pacifier can help meet their developmental needs by providing soothing comfort. Choices B, C, and D do not directly address the major developmental need related to the newborn's comfort and reflexes postoperatively. Putting a mobile over the crib, providing a cuddly toy, or warming formula, although potentially beneficial in other contexts, do not specifically target the developmental need of sucking for comfort. Offering a pacifier is a safe and effective way to address this developmental need in newborns.
