7.5 mL? tbsp1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). Convert 7.5 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.

7.5 mL1 tbsp = 15 mL
n = tbsp
2.Easy
60 mL? tbsp1 tbsp = 15 mL

Practice exercise (made-up values, not clinical guidance). Convert 60 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.

94969810010210410635363738394041°F°C99.3 °F? °C

Practice exercise (made-up values, not clinical guidance). A patient’s temperature is 99.3 °F. Convert it to degrees Celsius T with °C = (°F − 32) × 5/9. Round to one decimal place.

99.3 °F
T = °C
4.Medium
4 ft 6 in1 ft = 12 in1 in = 2.54 cmh = ? cm

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
12 mcg/min? mg/h1 h = 60 min1 mg = 1000 mcg

Practice exercise (made-up values, not clinical guidance). An infusion delivers 12 mcg/min. Express this dose rate D in mg/h.

12 mcg/min1 h = 60 min1 mg = 1000 mcg
D = mg/h
6.Hard
1 cup? mL½ fl oz? mL1 tsp? mLΣ = ? mL

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

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