Correct Answer: B

Rationale: Vomiting and poor appetite can be symptoms of neuroblastoma, a malignancy that affects the adrenal glands and sympathetic nervous system. A maculopapular rash on the palms (Choice A) is not typically associated with neuroblastoma. Irritability and poor weight gain (Choice C) may be non-specific findings and do not specifically point towards neuroblastoma. Auscultation findings of wheezing with diminished lung sounds (Choice D) are more indicative of respiratory conditions rather than neuroblastoma.

Correct Answer: B

Rationale: Given the diversity of families in today's society, some believe that family should be defined as whatever the child and family say it is.

Correct Answer: A

Rationale: The correct answer is A: Teaching proper care procedures. In this scenario, focusing on teaching the mother proper care procedures is crucial as she is the nurturer in the family and will likely be the primary caregiver for the child. This will empower her to provide appropriate care and support for her daughter during the recovery process. Choices B, C, and D are not the most appropriate activities for the mother in this situation. Dealing with insurance coverage, determining treatment success, and transmitting information to family members are important but not as directly relevant to the immediate care needs of the child's broken arm.

Correct Answer: B

Rationale: The most important factor in preparing a toddler for additional surgery is their previous experience of hospitalization. This familiarity can help reduce anxiety and fear associated with the hospital environment and medical procedures. Choice A, satisfying the child's wishes, may not always be feasible or in the child's best interest during medical procedures. Choice C, preventing the child from being with strangers, may not address the core issue of preparing the child for surgery. Choice D, ensuring the child still receives parental affection, is important but may not directly address the preparation needed for surgery.

Correct Answer: B

Rationale: The correct answer is preventing infection. In caring for a child with acute lymphoblastic leukemia (ALL), preventing infection is the priority nursing intervention. Children with ALL are immunocompromised due to the disease and its treatment, making them more susceptible to infections. Administering chemotherapy, while important, is not the priority as preventing infection takes precedence to avoid complications. Monitoring for signs of bleeding and providing nutritional support are also essential components of care for a child with ALL, but preventing infection is the priority to ensure the child's safety and well-being.
