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: C

Rationale: Discussing how the body continuously makes blood helps the child understand that losing a small amount is normal and not harmful. This educational approach also helps reduce anxiety by giving the child a sense of control over the situation.

Rationale: Improvement in APIGN is indicated by an increase in urine output and a change in urine color from brown (due to hematuria) to a more normal appearance. This reflects a reduction in glomerular inflammation and improved kidney function. Choice B is incorrect because resting more comfortably is not a direct indicator of kidney function improvement. Choice C is incorrect because a decrease in appetite is not typically associated with improvement in APIGN. Choice D is incorrect because an increased BUN value would suggest worsening kidney function rather than improvement.

Correct Answer: C

Rationale: Giardia lamblia is a protozoan parasite known to cause acute diarrhea, often through contaminated water or food. Shigella, Salmonella, and E. coli are bacterial pathogens that also cause diarrhea but are not parasites.
