What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?
- A. Infarction of renal vessels
- B. Immune complex formation and glomerular deposition
- C. Bacterial endotoxin deposition on and destruction of glomeruli
- D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation
Correct Answer: B
Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

If the needs of the infant are met in a loving, consistent manner, the infant will develop a sense of:
- A. Trust
- B. Love
- C. Independence
- D. Responsibility
Correct Answer: A
Rationale: The correct answer is A: Trust. According to Erikson's psychosocial development theory, when infants receive consistent and loving care, they develop trust. This trust forms the basis of the first stage of psychosocial development, known as Trust vs. Mistrust. Trust is essential for healthy social and emotional development. Choice B, Love, is incorrect as it is more of an emotion than a developmental stage. Choice C, Independence, typically occurs later in development during Erikson's Autonomy vs. Shame and Doubt stage. Choice D, Responsibility, is also not the correct answer as it relates more to later stages of development where individuals develop a sense of duty and obligation.
What condition is the most common cause of acute renal failure in children?
- A. Pyelonephritis
- B. Tubular destruction
- C. Severe dehydration
- D. Upper tract obstruction
Correct Answer: C
Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.
Which clinical manifestations should the nurse anticipate when assessing a child for hypoglycemia?
- A. Lethargy
- B. Thirst
- C. Nausea and vomiting
- D. Shaky feeling and dizziness
Correct Answer: D
Rationale: The correct answer is D: 'Shaky feeling and dizziness.' Hypoglycemia in children often presents with symptoms like shakiness, dizziness, sweating, hunger, and irritability. These symptoms occur because the brain and body are deprived of the glucose they need to function properly. Choices A, B, and C are incorrect because lethargy, thirst, nausea, and vomiting are not typically primary manifestations of hypoglycemia in children.
What statement is an advantage of peritoneal dialysis compared with hemodialysis?
- A. Protein loss is less extensive.
- B. Dietary limitations are not necessary.
- C. It is easy to learn and safe to perform.
- D. It is needed less frequently than hemodialysis.
Correct Answer: C
Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.

- D. 8 to 9 years
Correct Answer: B
