Question

white blood cell casts in the urine suggest:
cystitis (bladder infection)
leukemia
pyelonephritis
decrease urine ph

Explanation:

White blood cell (WBC) casts in urine are associated with kidney infections. Pyelonephritis is a kidney infection, while cystitis is a bladder infection (WBC casts are less typical here), leukemia is a blood cancer (not directly indicated by WBC casts in urine), and urine pH change isn't suggested by WBC casts. So the correct answer should be pyelonephritis, but the selected option in the image is incorrect. However, to answer based on the question's context (correct medical knowledge), the right option is the one for pyelonephritis. But as per the options, the correct medical answer is pyelonephritis, so the option is:

Answer:

C. pyelonephritis (assuming options are labeled A: cystitis, B: leukemia, C: pyelonephritis, D: decrease urine pH; if original labels differ, adjust, but based on medical knowledge, white blood cell casts in urine suggest pyelonephritis (kidney infection), so the correct option is the one with pyelonephritis.
