1.Easy
kg× 1000g× 1000mg× 1000mcg200 mcg?

Practice exercise (made-up values, not clinical guidance). Convert 200 mcg to mg: find x.

200 mcg1 mg = 1000 mcg
x = mg
2.Easy
L× 1000mL750 mL?

Practice exercise (made-up values, not clinical guidance). Convert 750 mL to L: find x.

750 mL1 L = 1000 mL
x = L
3.Medium
194.327 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 194.327 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

194.327 gtt/min
x = gtt/min
4.Medium

6.Hard
10 mg/h? mcg/min1 mg = 1000 mcg1 h = 60 min

Practice exercise (made-up values, not clinical guidance). An infusion delivers 10 mg/h. Express this dose rate D in mcg/min. Round to one decimal place.

10 mg/h1 mg = 1000 mcg1 h = 60 min
D = mcg/min

Answer key

  1. 1. x = 0.2 mg
  2. 2. x = 0.75 L
  3. 3. x = 194 gtt/min
  4. 4. 9:45 PM
  5. 5. t = 6.5 h
