1.Easy
kg× 1000g× 1000mg× 1000mcg0.05 g?

Practice exercise (made-up values, not clinical guidance). Convert 0.05 g to mg: find x.

0.05 g1 g = 1000 mg
x = mg
2.Easy
14 lb1 kg = 2.2 lbm = ? kg

Practice exercise (made-up values, not clinical guidance). A patient weighs 14 lb. Using 1 kg = 2.2 lb, find the weight m in kilograms. Round to one decimal place.

14 lb1 kg = 2.2 lb
m = kg
3.Medium
94969810010210410635363738394041°F°C? °F40 °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 40 °C. Convert it to degrees Fahrenheit T with °F = °C × 9/5 + 32. Round to one decimal place.

40 °C
T = °F
4.Medium
93.918 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 93.918 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

93.918 gtt/min
x = gtt/min
5.Hard
2 mg/h? mcg/min1 mg = 1000 mcg1 h = 60 min

Practice exercise (made-up values, not clinical guidance). An infusion delivers 2 mg/h. Express this dose rate D in mcg/min. Round to one decimal place.

2 mg/h1 mg = 1000 mcg1 h = 60 min
D = mcg/min
6.Hard
14.4 g/dL? g/L1 L = 10 dL

Practice exercise (made-up values, not clinical guidance). A haemoglobin result is 14.4 g/dL. Express it in g/L Hb.

14.4 g/dL1 L = 10 dL
Hb = g/L

Answer key

  1. 1. x = 50 mg
  2. 2. m = 6.4 kg
  3. 3. T = 104 °F
  4. 4. x = 94 gtt/min
  5. 5. D = 33.3 mcg/min
  6. 6. Hb = 144 g/L
