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

Practice exercise (made-up values, not clinical guidance). Convert 15 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.

15 mL1 fl oz = 30 mL
n = fl oz
2.Easy
19 lb1 kg = 2.2 lbm = ? kg

Practice exercise (made-up values, not clinical guidance). A patient weighs 19 lb. Using 1 kg = 2.2 lb, find the weight m in kilograms. Round to one decimal place.

19 lb1 kg = 2.2 lb
m = kg
3.Medium
124.989 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 124.989 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

124.989 gtt/min
x = gtt/min
4.Medium
4.8621 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 4.8621 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?

4.8621 mL
x = mL
5.Hard
4 mg/dL? µmol/L1 mg/dL = 88.4 µmol/L

Practice exercise (made-up values, not clinical guidance). A serum creatinine result is 4 mg/dL. Using 1 mg/dL = 88.4 µmol/L for creatinine, find c in µmol/L to the nearest whole number.

4 mg/dL1 mg/dL = 88.4 µmol/L
c = µmol/L
6.Hard
1½ cups? mL1 tsp? mL½ fl oz? mLΣ = ? mL

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes 1½ cups of tea, 1 tsp of cough syrup, ½ fl oz of juice. Using the equivalents given, find the total oral intake V in mL.

1 cup = 8 fl oz = 240 mL1 tsp = 5 mL1 fl oz = 30 mL
V = mL

Answer key

  1. 1. n = 0.5 fl oz
  2. 2. m = 8.6 kg
  3. 3. x = 125 gtt/min
  4. 4. x = 4.9 mL
  5. 5. c = 354 µmol/L
  6. 6. V = 380 mL
