1.Easy
4 tbsp? mL1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). Convert 4 tbsp to millilitres, using 1 tbsp = 15 mL. Find V.

4 tbsp1 tbsp = 15 mL
V = mL
2.Easy
kg× 1000g× 1000mg× 1000mcg125 mg?

Practice exercise (made-up values, not clinical guidance). Convert 125 mg to g: find x.

125 mg1 g = 1000 mg
x = g
3.Medium
111.236 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 111.236 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

111.236 gtt/min
x = gtt/min
4.Medium
70.5615 kg? kground to 0.1 kg

Practice exercise (made-up values, not clinical guidance). A weight conversion gives 70.5615 kg. The rule in this exercise is that weights are rounded to the nearest tenth of a kilogram. What value x do you record?

70.5615 kg
x = kg
5.Hard
8 mcg/kg/min? mg/h74 kg1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An order reads 8 mcg/kg/min for a patient who weighs 74 kg. Express the dose rate D in mg/h. Round to two decimal places.

8 mcg/kg/min74 kg
D = mg/h
6.Hard
25 mL/h? L/day1 day = 24 h1 L = 1000 mL

Practice exercise (made-up values, not clinical guidance). A maintenance infusion runs at 25 mL/h without a break. How many litres V does it deliver in 24 hours?

25 mL/h24 h
V = L

Answer key

  1. 1. V = 60 mL
  2. 2. x = 0.125 g
  3. 3. x = 111 gtt/min
  4. 4. x = 70.6 kg
  5. 5. D = 35.52 mg/h
  6. 6. V = 0.6 L
