1.Easy
360 mL? cups1 cup = 8 fl oz = 240 mL

Practice exercise (made-up values, not clinical guidance). Convert 360 mL to cups, using 1 cup = 8 fl oz = 240 mL: how many n? Real liquid doses are always measured in mL, with an oral syringe or a marked medicine cup.

360 mL1 cup = 8 fl oz = 240 mL
n = cups
2.Easy
kg× 1000g× 1000mg× 1000mcg2.5 g?

Practice exercise (made-up values, not clinical guidance). Convert 2.5 g to mg: find x.

2.5 g1 g = 1000 mg
x = mg
3.Medium
145 cm1 in = 2.54 cmh = ? in

Practice exercise (made-up values, not clinical guidance). A patient is 145 cm tall. Using 1 in = 2.54 cm, find the height h in inches. Round to one decimal place.

145 cm1 in = 2.54 cm
h = in
4.Medium
6 ft 9 in1 ft = 12 in1 in = 2.54 cmh = ? cm

Practice exercise (made-up values, not clinical guidance). A patient is 6 ft 9 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 9 in1 ft = 12 in1 in = 2.54 cm
h = cm
5.Hard
½ fl oz? mL1 tsp? mL½ tbsp? mLΣ = ? mL

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes ½ fl oz of juice, 1 tsp of cough syrup, ½ tbsp of liquid supplement. Using the equivalents given, find the total oral intake V in mL.

1 fl oz = 30 mL1 tsp = 5 mL1 tbsp = 15 mL
V = mL
6.Hard
3 mcg/min? mg/h1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An infusion delivers 3 mcg/min. Express this dose rate D in mg/h.

3 mcg/min1 h = 60 min1 mg = 1000 mcg
D = mg/h

Answer key

  1. 1. n = 1.5 cups
  2. 2. x = 2500 mg
  3. 3. h = 57.1 in
  4. 4. h = 206 cm
  5. 5. V = 27.5 mL
  6. 6. D = 0.18 mg/h
