1.7 mg/dL? µmol/L1 mg/dL = 88.4 µmol/L

Practice exercise (made-up values, not clinical guidance). A serum creatinine result is 1.7 mg/dL. Using 1 mg/dL = 88.4 µmol/L for creatinine, find c in µmol/L to the nearest whole number.

1.7 mg/dL1 mg/dL = 88.4 µmol/L
c = µmol/L
6.Hard
8 mg/h? mcg/min1 mg = 1000 mcg1 h = 60 min

Practice exercise (made-up values, not clinical guidance). An infusion delivers 8 mg/h. Express this dose rate D in mcg/min. Round to one decimal place.

8 mg/h1 mg = 1000 mcg1 h = 60 min
