MT AAB ChemistryA 40-year-old male has a randome glucose of 470 mg/dL. This lab finding is consistent with
which one of the following clinical conditions? - correct answer-Diabetes mellitus
A creatinine clearance test is performed. The 24-hour urine volume is 770 mL; serum
creatinine is 2.0 mg/dL and urine creatinine is 240 mg/dL. What is the clearance, assuming
