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
kg× 1000g× 1000mg× 1000mcg100 mg?

Practice exercise (made-up values, not clinical guidance). Convert 100 mg to g: find x.

100 mg1 g = 1000 mg
x = g

94969810010210410635363738394041°F°C? °F36.5 °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 36.5 °C. Convert it to degrees Fahrenheit T with °F = °C × 9/5 + 32. Round to one decimal place.

36.5 °C
T = °F
4.Medium
4 ft 8 in1 ft = 12 in1 in = 2.54 cmh = ? cm

Practice exercise (made-up values, not clinical guidance). A patient is 4 ft 8 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 8 in1 ft = 12 in1 in = 2.54 cm
h = cm
5.Hard
120 mL/h? L/day1 day = 24 h1 L = 1000 mL

Practice exercise (made-up values, not clinical guidance). A maintenance infusion runs at 120 mL/h without a break. How many litres V does it deliver in 24 hours?

120 mL/h24 h
V = L
6.Hard

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes 6 fl oz of juice, ¼ cup of tea, ½ tsp of cough syrup, 1½ tbsp of liquid supplement. Using the equivalents given, find the total oral intake V in mL.

1 fl oz = 30 mL1 cup = 8 fl oz = 240 mL1 tsp = 5 mL1 tbsp = 15 mL
V = mL
