3.Medium
3.6776 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 3.6776 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?

3.6776 mL
x = mL
4.Medium
94969810010210410635363738394041°F°C? °F39.1 °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 39.1 °C. Convert it to degrees Fahrenheit T with °F = °C × 9/5 + 32. Round to one decimal place.

39.1 °C
T = °F
5.Hard
150 mL/h? L/day1 day = 24 h1 L = 1000 mL

Practice exercise (made-up values, not clinical guidance). A maintenance infusion runs at 150 mL/h without a break. How many litres V does it deliver in 24 hours?

150 mL/h24 h
V = L
6.Hard
