Correct Answer: D

Rationale: The correct answer is D. Novolin N insulin peaks in the evening, leading to a higher risk of hypoglycemia during this time. Providing a snack before bedtime helps counteract the late insulin activity and prevent hypoglycemia. Choice A is incorrect as the primary reason for the snack is related to insulin activity rather than diet compliance. Choice B is not directly related to the timing of Novolin N insulin administration. Choice C is unrelated to the specific need for a snack in the evening to address insulin activity.

Correct Answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome due to their immunosuppressive effects, which help reduce proteinuria and control the disease progression. Antihypertensive agents are not the primary treatment for this condition and are typically used to manage hypertension that may result from nephrotic syndrome. Long-term diuretics are not indicated in the treatment of minimal change nephrotic syndrome as they do not address the underlying cause. Increasing fluids to promote diuresis is not a recommended treatment for minimal change nephrotic syndrome, as it can exacerbate edema and fluid overload in these patients.

Correct Answer: A

Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.

Correct Answer: A

Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus causes excessive thirst and urination, leading to fluid imbalance and potential dehydration. Choice B, excess fluid volume related to edema, is not a priority as diabetes insipidus is characterized by fluid loss, not retention. Choice C, deficient knowledge related to fluid intake regimen, may be important but is not the priority when the child is at risk of dehydration. Choice D, imbalanced nutrition related to excess weight, is not directly associated with the primary concern of fluid volume imbalance in diabetes insipidus.
