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

Practice exercise (made-up values, not clinical guidance). Convert 240 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.

240 mL1 fl oz = 30 mL
n = fl oz
2.Easy
5 mL? tsp1 tsp = 5 mL

Practice exercise (made-up values, not clinical guidance). Convert 5 mL to tsp, using 1 tsp = 5 mL: how many n? Real liquid doses are always measured in mL, with an oral syringe or a marked medicine cup.

5 mL1 tsp = 5 mL
n = tsp
3.Medium
0.17109 mL? mLround to 0.01 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for a small injection gives 0.17109 mL. The rule in this exercise is that volumes below 1 mL are rounded to the nearest hundredth of a mL. What value x do you record?

0.17109 mL
x = mL
4.Medium
152.561 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 152.561 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

152.561 gtt/min
x = gtt/min
5.Hard
1½ tsp · 3/day · 14 d? × 150 mL1 tsp = 5 mL

Practice exercise (made-up values, not clinical guidance). A prescription reads 1½ tsp of an oral suspension three times a day for 14 days. The suspension comes in 150 mL bottles. Using 1 tsp = 5 mL, how many whole bottles N must be supplied so the course is complete?

N =
6.Hard
4 mcg/kg/min? mg/h96 kg1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An order reads 4 mcg/kg/min for a patient who weighs 96 kg. Express the dose rate D in mg/h. Round to two decimal places.

4 mcg/kg/min96 kg
D = mg/h

  1. 1. n = 8 fl oz
  2. 2. n = 1 tsp
  3. 3. x = 0.17 mL
  4. 4. x = 153 gtt/min
  5. 5. N = 3
