Question 1 of 5
What diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?
Correct Answer: A
Rationale: Renal ultrasonography uses ultrasonic waves to visualize renal structures without radiation or isotopes. CT and intravenous pyelography involve external radiation, often with contrast, and voiding cystourethrography uses radiation and contrast injected into the bladder.
Question 2 of 5
A girl, age 5 1/2 years, has been sent to the school nurse for urinary incontinence three times in the past 2 days. The nurse should recommend to her parent that the first action is to have the child evaluated for what condition?
Correct Answer: C
Rationale: Incontinence in a toilet-trained 5½-year-old girl suggests a UTI, common in this age group. UTI evaluation precedes psychosocial causes like school phobia or ADHD, and glomerulonephritis typically presents with reduced urine output and fluid retention, not incontinence.
Question 3 of 5
What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?
Correct Answer: B
Rationale: Postinfectious glomerulonephritis results from immune complexes formed after streptococcal infection, depositing in glomerular capillaries. Renal vessel infarction occurs in sickle cell disease, bacterial endotoxins aren?t involved, and embolization is linked to bacterial endocarditis.
Question 4 of 5
What is the primary objective of care for the child with minimal change nephrotic syndrome (MCNS)?
Correct Answer: C
Rationale: The primary goal in MCNS is to minimize urinary protein excretion, reducing edema and complications. Blood pressure is typically normal, serum protein levels need to increase, and fluid retention (edema) is a problem to be reduced, not increased.
Question 5 of 5
What measure of fluid balance status is most useful in a child with acute glomerulonephritis?
Correct Answer: B
Rationale: Daily weight is the most accurate measure of fluid balance in acute glomerulonephritis, reflecting edema changes. Proteinuria indicates disease severity, specific gravity is unreliable due to proteinuria and hematuria, and intake/output is less accurate, especially in non-toilet-trained children.
