kg× 1000g× 1000mg× 1000mcg0.125 mg?

Practice exercise (made-up values, not clinical guidance). Convert 0.125 mg to mcg: find x.

0.125 mg1 mg = 1000 mcg
x = mcg
2.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
3.Medium
13.2134 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 13.2134 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?

13.2134 mL
x = mL
4.Medium
40.9202 kg? kground to 0.1 kg

Practice exercise (made-up values, not clinical guidance). A weight conversion gives 40.9202 kg. The rule in this exercise is that weights are rounded to the nearest tenth of a kilogram. What value x do you record?

40.9202 kg
x = kg

V = mL
6.Hard
½ tsp · 3/day · 10 d? mL1 tsp = 5 mL

Practice exercise (made-up values, not clinical guidance). A prescription reads ½ tsp of an oral suspension three times a day for 10 days. Using 1 tsp = 5 mL, how many mL V are needed for the whole course?

½ tspthree times a day10 days1 tsp = 5 mL
V = mL
