1.Easy
15 mL? tbsp1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). Convert 15 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.

15 mL1 tbsp = 15 mL
n = tbsp
2.Easy
kg× 1000g× 1000mg× 1000mcg1.2 kg?

Practice exercise (made-up values, not clinical guidance). Convert 1.2 kg to g: find x.

1.2 kg1 kg = 1000 g
x = g
3.Medium
175.554 gtt/min? gtt/minround to 1 gtt/min

Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 175.554 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?

175.554 gtt/min
x = gtt/min
4.Medium
94969810010210410635363738394041°F°C102 °F? °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 102 °F. Convert it to degrees Celsius T with °C = (°F − 32) × 5/9. Round to one decimal place.

102 °F
T = °C
5.Hard
½ cup? mL1 tbsp? mL2 tsp? mLΣ = ? mL

Practice exercise (made-up values, not clinical guidance). During a shift a patient takes ½ cup of tea, 1 tbsp of liquid supplement, 2 tsp of cough syrup. Using the equivalents given, find the total oral intake V in mL.

1 cup = 8 fl oz = 240 mL1 tbsp = 15 mL1 tsp = 5 mL
V = mL
6.Hard
00:0019:3008:30t = ?

Practice exercise (made-up values, not clinical guidance). An infusion starts at 19:30 and finishes at 08:30 the next morning (24-hour clock). How many minutes t did it run?

19:3008:30
t = min

Answer key

  1. 1. n = 1 tbsp
  2. 2. x = 1200 g
  3. 3. x = 176 gtt/min
  4. 4. T = 38.9 °C
  5. 5. V = 145 mL
  6. 6. t = 780 min
