2.Easy
Practice exercise (made-up values, not clinical guidance). Convert 30 mL to tbsp, using 1 tbsp = 15 mL: how many n? Real liquid doses are always measured in mL, with an oral syringe or a marked medicine cup.
30 mL1 tbsp = 15 mL
n = tbsp
3.Medium
Practice exercise (made-up values, not clinical guidance). A patient is 6 ft 10 in tall. Using 1 ft = 12 in and 1 in = 2.54 cm, find the height h in centimetres, to the nearest whole centimetre.
6 ft 10 in1 ft = 12 in1 in = 2.54 cm
h = cm
4.Medium
Practice exercise (made-up values, not clinical guidance). A patient is 4 ft 6 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 6 in1 ft = 12 in1 in = 2.54 cm
h = cm
5.Hard
Practice exercise (made-up values, not clinical guidance). An infusion starts at 23:05 and finishes at 07:40 the next morning (24-hour clock). How many hours t did it run? Give the answer in hours as a decimal, rounded to two decimal places.
23:0507:40
t = h
6.Hard
Practice exercise (made-up values, not clinical guidance). An order reads 8 mcg/kg/min for a patient who weighs 50 kg. Express the dose rate D in mg/h. Round to two decimal places.
8 mcg/kg/min50 kg
D = mg/h
Answer key
- 1. x = 2000 mcg
- 2. n = 2 tbsp
- 3. h = 208 cm
- 4. h = 137 cm
- 5. t = 8.58 h
- 6. D = 24 mg/h
