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.

Correct Answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

Correct Answer: B

Rationale: Signs of kidney transplant rejection include fever, diminished urinary output, and swelling/tenderness in the graft area. These symptoms indicate that the body may be rejecting the transplanted organ, requiring immediate medical attention.

Correct Answer: C

Rationale: When a parent's infant is born with physical defects, understanding the psychological reactions is crucial. The reaction is often similar to the grief experienced when facing the death of a child. Parents need to grieve for the loss of the expected child and adapt to the needs of a child with physical defects. The grief process typically involves stages like shock, frustration, and anger, which can last for years. Denial during the shock phase is not maladaptive but can help parents cope initially. Additionally, parents are sensitive to the behavior of health professionals, whose interactions can significantly influence the parents' reactions to the infant. Therefore, recognizing the similarity of the psychological reaction to grief is an important consideration in understanding how parents cope with their infant's physical defects.
