A 24 -hour urine has a total volume of $1,200 \mathrm{~mL}$. A $1: 200$ dilution of the urine specimen gives a creatinine result of $0.8 \mathrm{mg} / \mathrm{dL}$. The serum value is $1.2 \mathrm{mg} / \mathrm{dL}$. What is the final value of creatinine in $\mathrm{mg} / \mathrm{dL}$ in the undiluted urine sample? a. 160 b. $0.8$ c. 960 d. 860

A man is in steady state making and excreting 1 mg creatinine per minute with plasma creatinine concentration 10 mg/liter. His urine creatinine concentration is 500 mg/liter. Every 300 minutes half of the creatinine molecules in his body are being excreted and replaced by new creatinine molecules. Assume that creatinine is an ideal marker of GFR and that mixing of creatinine occurs instantaneously throughout the total body water. A. Calculate the total body water. Suddenly, his GFR declines by half while the man remains in fluid balance. B. Calculate the serum creatinine concentration after 6 hours.
