1.Easy
120 mL? fl oz1 fl oz = 30 mL

Practice exercise (made-up values, not clinical guidance). Convert 120 mL to fl oz, using 1 fl oz = 30 mL: how many n? Real liquid doses are always measured in mL, with an oral syringe or a marked medicine cup.

120 mL1 fl oz = 30 mL
n = fl oz
2.Easy
kg× 1000g× 1000mg× 1000mcg0.5 mg?

Practice exercise (made-up values, not clinical guidance). Convert 0.5 mg to mcg: find x.

0.5 mg1 mg = 1000 mcg
x = mcg
3.Medium
13.5013 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 13.5013 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?

13.5013 mL
x = mL
4.Medium
12.1115 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 12.1115 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?

12.1115 mL
x = mL
5.Hard
6 mcg/min? mg/h1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An infusion delivers 6 mcg/min. Express this dose rate D in mg/h.

6 mcg/min1 h = 60 min1 mg = 1000 mcg
D = mg/h
6.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
