1.Easy
L× 1000mL2500 mL?

Practice exercise (made-up values, not clinical guidance). Convert 2500 mL to L: find x.

2500 mL1 L = 1000 mL
x = L
2.Easy
kg× 1000g× 1000mg× 1000mcg0.1 g?

Practice exercise (made-up values, not clinical guidance). Convert 0.1 g to mg: find x.

0.1 g1 g = 1000 mg
x = mg
3.Medium
10.9721 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 10.9721 mL. The rule in this exercise is that volumes of 1 mL or more are rounded to the nearest tenth of a mL. What value x do you record?

10.9721 mL
x = mL
4.Medium
94969810010210410635363738394041°F°C99.8 °F? °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 99.8 °F. Convert it to degrees Celsius T with °C = (°F − 32) × 5/9. Round to one decimal place.

99.8 °F
T = °C
5.Hard
1½ cups? mL1 tsp? mL8 fl oz? mL1 tbsp? mLΣ = ? mL

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes 1½ cups of tea, 1 tsp of cough syrup, 8 fl oz of juice, 1 tbsp of liquid supplement. Using the equivalents given, find the total oral intake V in mL.

1 cup = 8 fl oz = 240 mL1 tsp = 5 mL1 fl oz = 30 mL1 tbsp = 15 mL
V = mL
6.Hard
4 mcg/min? mg/h1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An infusion delivers 4 mcg/min. Express this dose rate D in mg/h.

4 mcg/min1 h = 60 min1 mg = 1000 mcg
D = mg/h

Answer key

  1. 1. x = 2.5 L
  2. 2. x = 100 mg
  3. 3. x = 11 mL
  4. 4. T = 37.7 °C
  5. 5. V = 620 mL
  6. 6. D = 0.24 mg/h
