1.Easy
3 cups? mL1 cup = 8 fl oz = 240 mL

Practice exercise (made-up values, not clinical guidance). Convert 3 cups to millilitres, using 1 cup = 8 fl oz = 240 mL. Find V.

3 cups1 cup = 8 fl oz = 240 mL
V = mL
2.Easy
kg× 1000g× 1000mg× 1000mcg325 mg?

Practice exercise (made-up values, not clinical guidance). Convert 325 mg to g: find x.

325 mg1 g = 1000 mg
x = g
3.Medium
94969810010210410635363738394041°F°C? °F40.8 °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 40.8 °C. Convert it to degrees Fahrenheit T with °F = °C × 9/5 + 32. Round to one decimal place.

40.8 °C
T = °F
4.Medium
0.71344 mL? mLround to 0.01 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for a small injection gives 0.71344 mL. The rule in this exercise is that volumes below 1 mL are rounded to the nearest hundredth of a mL. What value x do you record?

0.71344 mL
x = mL
5.Hard
2 tsp · 4/day · 14 d? × 150 mL1 tsp = 5 mL

Practice exercise (made-up values, not clinical guidance). A prescription reads 2 tsp of an oral suspension every 6 hours for 14 days. The suspension comes in 150 mL bottles. Using 1 tsp = 5 mL, how many whole bottles N must be supplied so the course is complete?

6.Hard
262 µmol/L? mg/dL1 mg/dL = 88.4 µmol/L

Practice exercise (made-up values, not clinical guidance). A serum creatinine result is 262 µmol/L. Using 1 mg/dL = 88.4 µmol/L for creatinine, find c in mg/dL. Round to two decimal places.

262 µmol/L1 mg/dL = 88.4 µmol/L
c = mg/dL

  1. 1. V = 720 mL
  2. 2. x = 0.325 g
  3. 3. T = 105.4 °F
  4. 4. x = 0.71 mL
  5. 5. N = 4
  6. 6. c = 2.96 mg/dL
