The nurse is aware that the following laboratory values supports a diagnosis of pyelonephritis?
a. Myoglobinuria
b. Ketonuria
c. Pyuria
d. Low white blood cell (WBC) count

Answer C.
Pyelonephritis is diagnosed by the presence of leukocytosis, hematuria, pyuria, and bacteriuria. The client exhibits fever, chills, and flank pain. Because there is often a septic picture, the WBC count is more likely to be high rather than low, as indicated in option D. Ketonuria indicates a diabetic state.
