Which test result would the nurse least likely expect to find in a child diagnosed with Wilms tumor?
A) Complete blood count (CBC) within normal limits
B) Urinalysis positive for blood
C) Mass on kidney
D) Elevated homovanillic acid (HVA) with 24-hour urine collection
D
Feedback:
Levels of HVA and vanillylmandelic acid (VMA) will not be elevated with Wilms tumor; they are elevated with neuroblastoma. CBC, blood urea nitrogen (BUN), and creatinine usually are within normal limits. Urinalysis may reveal hematuria or leukocytes. Renal or abdominal ultrasound would reveal a mass on the kidney.
