Correct Answer: D

Rationale: Negativism in toddlers is a common behavior at this age as they begin to assert their independence and show a desire to control their environment. Choice A, 'Trust,' does not align with the behavior of negativism, as it is more about the child's growing autonomy. Choice B, 'Attention,' while important for child development, is not the primary need being met by negativism in this context. Choice C, 'Discipline,' though important in guiding behavior, is not the underlying need being expressed through negativism. Therefore, the correct answer is D, 'Independence,' as toddlers exhibit negativism as a way to assert their independence and autonomy.

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: B

Rationale: The short urethra in young girls is a significant factor that predisposes them to urinary tract infections. Girls have a shorter urethra than boys, making it easier for bacteria to travel up the urinary tract, leading to infections. Increased fluid intake (Choice A) is actually a preventive measure as it helps flush out bacteria from the urinary tract. Prostatic secretions in males (Choice C) do not predispose the urinary tract to infection in children. Frequent emptying of the bladder (Choice D) is also a good practice to prevent urinary tract infections by reducing the chances of bacterial growth in the urinary tract.

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: A

Rationale: Preventing shivering is crucial in this scenario as it can increase body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat through muscle activity, which can elevate the body temperature. Restricting oral fluids (choice B) is inappropriate as maintaining hydration is vital, especially in cases of fever and vomiting. Measuring output hourly (choice C) and taking vital signs hourly (choice D) are important nursing actions but not the most critical in this case where preventing shivering takes precedence.
