1.Easy
kg× 1000g× 1000mg× 1000mcg0.025 mg?

Practice exercise (made-up values, not clinical guidance). Convert 0.025 mg to mcg: find x.

0.025 mg1 mg = 1000 mcg
x = mcg
2.Easy
1 fl oz? mL1 fl oz = 30 mL

Practice exercise (made-up values, not clinical guidance). Convert 1 fl oz to millilitres, using 1 fl oz = 30 mL. Find V.

1 fl oz1 fl oz = 30 mL
V = mL
3.Medium
4 ft 7 in1 ft = 12 in1 in = 2.54 cmh = ? cm

Practice exercise (made-up values, not clinical guidance). A patient is 4 ft 7 in tall. Using 1 ft = 12 in and 1 in = 2.54 cm, find the height h in centimetres, to the nearest whole centimetre.

4 ft 7 in1 ft = 12 in1 in = 2.54 cm
h = cm
4.Medium
7 lb 5 oz? kg1 lb = 16 oz1 kg = 2.2 lb

Practice exercise (made-up values, not clinical guidance). A newborn weighs 7 lb 5 oz. Using 1 lb = 16 oz and 1 kg = 2.2 lb, find the weight m in kilograms. Round to two decimal places.

7 lb 5 oz1 lb = 16 oz1 kg = 2.2 lb
m = kg
5.Hard
4 tbsp? mL1 cup? mL2½ tsp? mLΣ = ? mL

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes 4 tbsp of liquid supplement, 1 cup of tea, 2½ tsp of cough syrup. Using the equivalents given, find the total oral intake V in mL.

1 tbsp = 15 mL1 cup = 8 fl oz = 240 mL1 tsp = 5 mL
V = mL
6.Hard
146 µmol/L? mg/dL1 mg/dL = 88.4 µmol/L

Practice exercise (made-up values, not clinical guidance). A serum creatinine result is 146 µmol/L. Using 1 mg/dL = 88.4 µmol/L for creatinine, find c in mg/dL. Round to two decimal places.

146 µmol/L1 mg/dL = 88.4 µmol/L
c = mg/dL

  1. 1. x = 25 mcg
  2. 2. V = 30 mL
  3. 3. h = 140 cm
  4. 4. m = 3.32 kg
  5. 5. V = 312.5 mL
  6. 6. c = 1.65 mg/dL
