1.Easy
Practice exercise (made-up values, not clinical guidance). A patient weighs 312 lb. Using 1 kg = 2.2 lb, find the weight m in kilograms. Round to one decimal place.
312 lb1 kg = 2.2 lb
m = kg
Nursing math & unit conversions worksheet with answers
2.Easy
Practice exercise (made-up values, not clinical guidance). Convert 125 mcg to mg: find x.
125 mcg1 mg = 1000 mcg
x = mg
3.Medium
Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 114.861 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?
114.861 gtt/min
x = gtt/min
4.Medium
Practice exercise (made-up values, not clinical guidance). A patient is 4 ft 0 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 0 in1 ft = 12 in1 in = 2.54 cm
h = cm
5.Hard
Practice exercise (made-up values, not clinical guidance). During a shift a patient takes 1½ fl oz of juice, ½ cup of tea, 3 tbsp of liquid supplement, 2½ tsp of cough syrup. Using the equivalents given, find the total oral intake V in mL.
1 fl oz = 30 mL1 cup = 8 fl oz = 240 mL1 tbsp = 15 mL1 tsp = 5 mL
V = mL
6.Hard
Practice exercise (made-up values, not clinical guidance). An order reads 1 mcg/kg/min for a patient who weighs 54 kg. Express the dose rate D in mg/h. Round to two decimal places.
1 mcg/kg/min54 kg
D = mg/h
Answer key
- 1. m = 141.8 kg
- 2. x = 0.125 mg
- 3. x = 115 gtt/min
- 4. h = 122 cm
- 5. V = 222.5 mL
- 6. D = 3.24 mg/h
