1.Easy
½ tbsp? mL1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). Convert ½ tbsp to millilitres, using 1 tbsp = 15 mL. Find V.

½ tbsp1 tbsp = 15 mL
V = mL
2.Easy
kg× 1000g× 1000mg× 1000mcg0.001 g?

Practice exercise (made-up values, not clinical guidance). Convert 0.001 g to mcg: find x.

0.001 g1 g = 1 000 000 mcg
x = mcg
3.Medium
94969810010210410635363738394041°F°C? °F39.8 °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 39.8 °C. Convert it to degrees Fahrenheit T with °F = °C × 9/5 + 32. Round to one decimal place.

39.8 °C
T = °F
4.Medium
0.16693 mL? mLround to 0.01 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for a small injection gives 0.16693 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?

0.16693 mL
x = mL
5.Hard
120 mL/h? L/day1 day = 24 h1 L = 1000 mL

Practice exercise (made-up values, not clinical guidance). A maintenance infusion runs at 120 mL/h without a break. How many litres V does it deliver in 24 hours?

120 mL/h24 h
V = L
6.Hard
150 g/L? g/dL1 L = 10 dL

Practice exercise (made-up values, not clinical guidance). A haemoglobin result is 150 g/L. Express it in g/dL Hb.

150 g/L1 L = 10 dL
Hb = g/dL

Answer key

  1. 1. V = 7.5 mL
  2. 2. x = 1000 mcg
  3. 3. T = 103.6 °F
  4. 4. x = 0.17 mL
  5. 5. V = 2.88 L
  6. 6. Hb = 15 g/dL
