Correct Answer: D

Rationale: The correct answer is D: Dramatic play. Dramatic play involves children acting out experiences to better understand them and reduce fear. In this scenario, by giving the teddy bear a 'shot' first, the nurse is engaging in dramatic play to help the child comprehend and feel more comfortable with the upcoming injection.\n A: Critical play involves critical thinking and problem-solving, not acting out scenarios.\n B: Role play typically involves pretending to be someone else, not necessarily acting out a specific experience.\n C: Diversionary activity aims to distract or redirect attention, which is different from the purpose of dramatic play in this context.

Correct Answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

Correct Answer: B

Rationale: By the age of eleven, many children are capable of administering their own insulin injections with supervision, fostering independence and better management of their diabetes. This age is appropriate for the child to take on more responsibility for their care. While parental involvement is still crucial for supervision and guidance, the child can start to learn and perform the injections themselves. Choice A is incorrect because parental involvement is important for safety and proper technique. Choice C is incorrect as waiting until closer to adolescence may delay the child's ability to manage their diabetes effectively. Choice D is incorrect as reaching injection sites is not the sole criteria; proper technique and supervision are essential.

Correct Answer: A

Rationale: After rehydration, a regular diet is generally recommended to ensure proper nutrition and recovery. A regular diet includes a balanced intake of all food groups and nutrients. Fruit juices may be too high in simple sugars and lack necessary nutrients, which can exacerbate diarrhea. While a high carbohydrate diet may be beneficial in some cases, a regular diet is more comprehensive. The BRAT diet, consisting of bananas, rice, apples, and toast or tea, was previously recommended for diarrhea, but it lacks adequate protein and fat, so a regular diet is now preferred for overall better nutrition and recovery.

Correct Answer: B

Rationale: The NCHS growth charts serve as reference guides for all racial or ethnic groups, including African American children. The 20th percentile for height and weight does not indicate nutritional failure but provides a reference point for ongoing assessment. Choice A is incorrect because being at the 20th percentile does not automatically imply the need for nutritional intervention. Choice C is incorrect as there is no correction factor specifically used for nonwhite ethnic groups in this context. Choice D is incorrect as a single measurement at the 20th percentile can provide valuable information for assessment.
