1.Easy
kg× 1000g× 1000mg× 1000mcg0.25 kg?

Practice exercise (made-up values, not clinical guidance). Convert 0.25 kg to g: find x.

0.25 kg1 kg = 1000 g
x = g
2.Easy
96 lb1 kg = 2.2 lbm = ? kg

Practice exercise (made-up values, not clinical guidance). A patient weighs 96 lb. Using 1 kg = 2.2 lb, find the weight m in kilograms. Round to one decimal place.

96 lb1 kg = 2.2 lb
m = kg
3.Medium
1.7199 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 1.7199 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?

1.7199 mL
x = mL
4.Medium
165 cm1 in = 2.54 cmh = ? in

Practice exercise (made-up values, not clinical guidance). A patient is 165 cm tall. Using 1 in = 2.54 cm, find the height h in inches. Round to one decimal place.

165 cm1 in = 2.54 cm
h = in
5.Hard
00:0022:3006:20t = ?

Practice exercise (made-up values, not clinical guidance). An infusion starts at 22:30 and finishes at 06:20 the next morning (24-hour clock). How many minutes t did it run?

22:3006:20
t = min
6.Hard
19.1 mmol/L? mg/dL1 mmol/L = 18 mg/dL

Practice exercise (made-up values, not clinical guidance). A blood glucose result is 19.1 mmol/L. Using 1 mmol/L = 18 mg/dL for glucose, find c in mg/dL to the nearest whole number.

19.1 mmol/L1 mmol/L = 18 mg/dL
c = mg/dL

Answer key

  1. 1. x = 250 g
  2. 2. m = 43.6 kg
  3. 3. x = 1.7 mL
  4. 4. h = 65 in
  5. 5. t = 470 min
  6. 6. c = 344 mg/dL
