How much in mls of the above suspension would you inform the nurse to administer to the patient during the first three days? (2 marks)

1 lbs = 0.45 kg

1.98 lbs = 1.98*0.45 kg = 0.89 kg

First dose/day 1: 0.89 * 20 = 17.8 mg

In HK ‘QD’ means once a day.

Dose Day 2: 0.89*10 = 8.9mg

Dose Day 3: 0.89*10 = 8.9mg

In total: 17.8 + 8.9 +8.9 = 35.6 mg

How much 10mg/ml soln to get 35.6mg:

Ratio == > 35.6/10 = 3.56 ml

You are asked to make a 60 day supply for the patient. How much of each ingredient would you need to ensure sufficient amount but minimal excess? (3 marks)

For a 60 day supply calculate one day of 17.8mg and 59 days of 8.9mg:

17.8mg + (59*8.9) = 542.9 mg

If you round up to 543 mg… this means you want 54.3ml of the 10mg/ml soln.

I would round up to at least 55 ml of soln. (Some may prefer 60ml)

The ratios in the recipe are 10:10:1000 (citrated caffeine: citric acid: distilled water)

To convert 1000 to 55 you multiply with the ratio of 55/1000

Then you use the same ratio to get the equivalent quantities of caffeine and citric acid.
10* (55/1000) = 0.55 g

Final answer:

0.55g citrated caffeine powder

0.55g citric acid USP

55 ml distilled water
