1.Easy
kg× 1000g× 1000mg× 1000mcg0.0025 g?

Practice exercise (made-up values, not clinical guidance). Convert 0.0025 g to mcg: find x.

0.0025 g1 g = 1 000 000 mcg
x = mcg
2.Easy
2 fl oz? mL1 fl oz = 30 mL

Practice exercise (made-up values, not clinical guidance). Convert 2 fl oz to millilitres, using 1 fl oz = 30 mL. Find V.

2 fl oz1 fl oz = 30 mL
V = mL
3.Medium
1.5672 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 1.5672 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?

1.5672 mL
x = mL
4.Medium
6 ft 11 in1 ft = 12 in1 in = 2.54 cmh = ? cm

Practice exercise (made-up values, not clinical guidance). A patient is 6 ft 11 in tall. Using 1 ft = 12 in and 1 in = 2.54 cm, find the height h in centimetres, to the nearest whole centimetre.

6 ft 11 in1 ft = 12 in1 in = 2.54 cm
h = cm
5.Hard
1½ cups? mL1 tsp? mL½ 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, ½ 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 tbsp = 15 mL
V = mL
6.Hard
2 mg/h? mcg/min1 mg = 1000 mcg1 h = 60 min

Practice exercise (made-up values, not clinical guidance). An infusion delivers 2 mg/h. Express this dose rate D in mcg/min. Round to one decimal place.

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

Answer key

  1. 1. x = 2500 mcg
  2. 2. V = 60 mL
  3. 3. x = 1.6 mL
  4. 4. h = 211 cm
  5. 5. V = 372.5 mL
  6. 6. D = 33.3 mcg/min
