Correct Answer: C

Rationale: Fluid restriction is often necessary to manage severe edema associated with MCNS. Increasing protein is not typically recommended due to the risk of exacerbating proteinuria, and calorie reduction is not generally needed.

Correct Answer: D

Rationale: Early repair of congenital genitourinary defects like hypospadias is important to promote a normal body image and avoid psychological issues as the child grows. It also helps prevent urinary complications and allows for normal development.

Correct Answer: C

Rationale: The correct answer is C: Autonomy vs. shame and doubt. Erikson's developmental stage for toddlers focuses on the conflict between developing a sense of independence (autonomy) and feelings of inadequacy (shame and doubt). Encouraging toddlers to explore their environment and make choices helps them build self-confidence and independence. Choices A, B, and D are incorrect because trust vs. mistrust relates to infancy, industry vs. inferiority is associated with school-age children, and initiative vs. guilt is linked to preschoolers.

Correct Answer: C

Rationale: In acute renal failure, laboratory findings typically include hyperkalemia, hyponatremia, and elevated blood urea nitrogen (BUN) levels due to the kidneys' inability to excrete waste and balance electrolytes. Metabolic alkalosis is less common, with metabolic acidosis being more typical.

Correct Answer: B

Rationale: The Denver II Developmental Screening Test is used to assess a child's development in four areas: personal-social, fine motor-adaptive, language, and gross motor skills. It helps identify children who may need further evaluation. Choice A, behavior problems, is incorrect as the Denver II primarily focuses on developmental milestones rather than behavior. Choice C, body mass index, is unrelated to the assessment of child development. Choice D, infection likelihood, is also not evaluated by the Denver II test.
