1.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
2.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
3.Medium
9 lb 15 oz? kg1 lb = 16 oz1 kg = 2.2 lb

Practice exercise (made-up values, not clinical guidance). A newborn weighs 9 lb 15 oz. Using 1 lb = 16 oz and 1 kg = 2.2 lb, find the weight m in kilograms. Round to two decimal places.

9 lb 15 oz1 lb = 16 oz1 kg = 2.2 lb
m = kg
4.Medium
19.837 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 19.837 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

19.837 gtt/min
x = gtt/min
5.Hard
100 mL/h? L/day1 day = 24 h1 L = 1000 mL

Practice exercise (made-up values, not clinical guidance). A maintenance infusion runs at 100 mL/h without a break. How many litres V does it deliver in 24 hours?

100 mL/h24 h
V = L
6.Hard
2 tbsp? mL2 tsp? mL3 cups? mLΣ = ? mL

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes 2 tbsp of liquid supplement, 2 tsp of cough syrup, 3 cups of tea. Using the equivalents given, find the total oral intake V in mL.

1 tbsp = 15 mL1 tsp = 5 mL1 cup = 8 fl oz = 240 mL
V = mL

Answer key

  1. 1. x = 100 mg
  2. 2. V = 7.5 mL
  3. 3. m = 4.52 kg
  4. 4. x = 20 gtt/min
  5. 5. V = 2.4 L
  6. 6. V = 760 mL
