Correct Answer: A

Rationale: The correct answer is A. Most childhood cancers, such as leukemias and sarcomas, affect tissues rather than specific organs, unlike many adult cancers. Choice B is incorrect because childhood cancers can be localized or spread, similar to adult cancers. Choice C is incorrect because childhood cancers can be highly responsive to treatment, especially when diagnosed early. Choice D is incorrect because the majority of childhood cancers cannot be prevented as they are often due to genetic mutations or unknown causes.

Correct Answer: C

Rationale: Choice C indicates a need for further teaching because not all products are clearly labeled as latex-free. It is essential for the mother to understand that she should not solely rely on product labels to determine latex content. She should be encouraged to verify with manufacturers and consult healthcare providers for accurate information. Choices A, B, and D are correct responses. Wearing a medical alert identification, informing caregivers, and ensuring the boy avoids all contact with latex are crucial steps in managing his sensitivity to latex and preventing potential allergic reactions.

Correct Answer: A

Rationale: The correct answer is A: Incisors. In infants, incisors are usually the first teeth to erupt, typically around 6 months of age. These are the front teeth used for cutting food. Canines (Choice B), upper molars (Choice C), and lower molars (Choice D) typically erupt after the incisors. Canines are sharp teeth used for tearing food, while molars are flat teeth used for grinding food.

Correct Answer: A

Rationale: When assessing a 2-year-old child with abdominal pain and adequate perfusion, it is essential to examine the child in the parent's arms. This approach helps reduce anxiety, provide comfort, and establish trust with the child. Palpating the painful area of the abdomen first (Choice B) may cause discomfort and increase anxiety in the child. Placing the child supine and palpating the abdomen (Choice C) without considering the child's comfort and security may lead to resistance and inaccurate assessment. Separating the child from the parent (Choice D) can exacerbate the child's anxiety and hinder the examination process. Therefore, examining the child in the parent's arms is the most appropriate approach in this scenario.

Correct Answer: C

Rationale: The correct answer is C: A ready source of glucose should be available. When managing type 1 diabetes, it is crucial to have a quick source of glucose readily available in case of hypoglycemia. This ensures that the adolescent can quickly raise their blood sugar levels to prevent complications. Choices A, B, and D are incorrect as they do not address the immediate need for glucose in managing hypoglycemia. While it is important for meals to be consumed regularly and in a controlled manner, specifying that they should be eaten at home or foods weighed using a gram scale is not as critical as ensuring a quick source of glucose in emergency situations.
