1.Easy
2 cups? mL1 cup = 8 fl oz = 240 mL

Practice exercise (made-up values, not clinical guidance). Convert 2 cups to millilitres, using 1 cup = 8 fl oz = 240 mL. Find V.

2 cups1 cup = 8 fl oz = 240 mL
V = mL
2.Easy
15 mL? tbsp1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). Convert 15 mL to tbsp, using 1 tbsp = 15 mL: how many n? Real liquid doses are always measured in mL, with an oral syringe or a marked medicine cup.

15 mL1 tbsp = 15 mL
n = tbsp
3.Medium
5 lb 10 oz? kg1 lb = 16 oz1 kg = 2.2 lb

Practice exercise (made-up values, not clinical guidance). A newborn weighs 5 lb 10 oz. Using 1 lb = 16 oz and 1 kg = 2.2 lb, find the weight m in kilograms. Round to two decimal places.

5 lb 10 oz1 lb = 16 oz1 kg = 2.2 lb
m = kg
4.Medium
7.1319 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 7.1319 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?

7.1319 mL
x = mL
5.Hard
00:0023:0507:40t = ?

Practice exercise (made-up values, not clinical guidance). An infusion starts at 23:05 and finishes at 07:40 the next morning (24-hour clock). How many minutes t did it run?

23:0507:40
t = min
6.Hard
½ tbsp · 3/day · 7 d? mL1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). A prescription reads ½ tbsp of an oral suspension every 8 hours for 7 days. Using 1 tbsp = 15 mL, how many mL V are needed for the whole course?

½ tbspevery 8 hours7 days1 tbsp = 15 mL
V = mL

Answer key

  1. 1. V = 480 mL
  2. 2. n = 1 tbsp
  3. 3. m = 2.56 kg
  4. 4. x = 7.1 mL
  5. 5. t = 515 min
  6. 6. V = 157.5 mL
