Correct Answer: D

Rationale: Minimal change nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and edema due to the loss of protein in the urine. Hematuria, bacteriuria, and weight loss are not typical features of this condition.

Correct Answer: D

Rationale: The amount of hematuria is not a reliable indicator of the severity of renal trauma, as even minor injuries can cause significant bleeding, while severe injuries may result in little or no visible blood. Renal trauma should be evaluated through imaging and clinical assessment.

Correct Answer: A

Rationale: The correct action when intermittently gavage feeding a preterm infant is to allow the formula to flow by gravity. This method helps prevent overfeeding and aspiration, which can occur if the formula is delivered too quickly under pressure. Choice B is incorrect as sucking on the tube can cause complications. Choice C is incorrect as the tube is typically inserted through the mouth. Choice D is incorrect as steady pressure can lead to rapid delivery of the formula, increasing the risk of complications.

Correct Answer: A

Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.

Correct Answer: C

Rationale: In Erikson's theory of psychosocial development, school-age children typically focus on developing a sense of industry. This stage, occurring during middle childhood, involves the desire to feel competent and productive in their skills and abilities. Choices A, B, and D are incorrect because establishing trust in others (A) is related to the first stage of Erikson's theory (trust vs. mistrust) which occurs in infancy, developing a sense of autonomy (B) is linked to the second stage (autonomy vs. shame and doubt) which occurs in early childhood, and establishing a sense of identity (D) is associated with the fifth stage (identity vs. role confusion) which occurs in adolescence.
