*Solve the question with arbitrary number* Thank you!

3. A physician prescribes Drug X intravenously for a patient with CLS. The prescribing information is:

- Loading infusion (certain size bag mL bag)

Rapid administration (a given # of) /min for (a given # of) minutes

Maintenance infusion (250 mL bag)

Slow infusion     1.5mg/min for 4 hours.

- Drug X available as (certain ratio concentration) solution (20 mL vial). How many milliliters of Drug X (certain ratio concentration) solution is required to prepare the slow infusion (maintenance dose) using the 250 milliliter bag? Do not count volume of additive. (Answer to the nearest tenth of a milliliter - one decimal point)

4. Based on the information given in question 3 above, calculate the drip rate in drops per minute if the dropper set delivers (a given # of) drops per milliliter? (to the nearest full drop - no decimal point)

Explanation / Answer

1) The slow-infusion dose is, 1.5 mg/min

So, 60 mins needs 1.5*60 = 90 mg of drug.

4 hours need 360 mg of drug.

Assuming that the drug is available as 60 mg/vial of 20 mL volume, total drug volume needed is, 6 vials (60*6 = 360 ml). Thus, 20*6 = 120 ml of drug is needed for slow infusion over 4 hours.
