1.Easy
3 tsp? mL1 tsp = 5 mL

Practice exercise (made-up values, not clinical guidance). Convert 3 tsp to millilitres, using 1 tsp = 5 mL. Find V.

3 tsp1 tsp = 5 mL
V = mL
2.Easy
kg× 1000g× 1000mg× 1000mcg0.05 mg?

Practice exercise (made-up values, not clinical guidance). Convert 0.05 mg to mcg: find x.

0.05 mg1 mg = 1000 mcg
x = mcg
3.Medium
5 ft 3 in1 ft = 12 in1 in = 2.54 cmh = ? cm

Practice exercise (made-up values, not clinical guidance). A patient is 5 ft 3 in tall. Using 1 ft = 12 in and 1 in = 2.54 cm, find the height h in centimetres, to the nearest whole centimetre.

5 ft 3 in1 ft = 12 in1 in = 2.54 cm
h = cm
4.Medium
1.9059 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 1.9059 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?

1.9059 mL
x = mL
5.Hard
5 mcg/min? mg/h1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An infusion delivers 5 mcg/min. Express this dose rate D in mg/h.

5 mcg/min1 h = 60 min1 mg = 1000 mcg
D = mg/h
6.Hard
0.5 mg/h? mcg/min1 mg = 1000 mcg1 h = 60 min

Practice exercise (made-up values, not clinical guidance). An infusion delivers 0.5 mg/h. Express this dose rate D in mcg/min. Round to one decimal place.

0.5 mg/h1 mg = 1000 mcg1 h = 60 min
D = mcg/min

Answer key

  1. 1. V = 15 mL
  2. 2. x = 50 mcg
  3. 3. h = 160 cm
  4. 4. x = 1.9 mL
  5. 5. D = 0.3 mg/h
  6. 6. D = 8.3 mcg/min
