Correct Answer: D

Rationale: Children with MCNS in remission can usually return to school. Home schooling may be necessary only if there are complications. The other options show an understanding of proper care during remission.

Correct Answer: D

Rationale: The correct answer is D, regression. Regression occurs when a child reverts to an earlier behavior, such as having accidents after being successfully toilet trained. This regression often happens due to stress or changes in routine. Choices A, B, and C are incorrect because positive reinforcement involves encouraging desired behavior, desensitization is a process of reducing sensitivity to a stimulus, and phobia is an intense fear or aversion to a specific object or situation, none of which directly apply to the described situation of the child having accidents after being toilet trained.

Correct Answer: B

Rationale: The Numeric scale is the most appropriate tool for assessing pain in older children, like a 12-year-old, as they can comprehend and use numbers to indicate their pain levels accurately. The FLACC scale is typically used for nonverbal or preverbal children. The NIPS scale is designed for neonates and infants. The FACES scale is more commonly used in younger children who may have difficulty expressing their pain in other ways.

Correct Answer: C

Rationale: Water and sodium retention is a major complication in chronic renal failure, leading to hypertension and edema. Hypokalemia and metabolic alkalosis are less common, and while BUN levels rise, retention rather than excretion is problematic in chronic renal failure.

Correct Answer: B

Rationale: Avoiding additional salt is crucial to help manage edema in children with MCNS. While monitoring urine output is important, the other statements either misinterpret the need for prolonged school absence or misunderstand the risk associated with contact sports during steroid therapy.
