Question 22845: Hello, My name is Tim Hunt.
I need help with some problems, Please help me.
1. A 10 ml vial contains 40 mg of a drug. How many mcg would be administered by injection of 2 ml of the drug?

2. many milliliters of a liquid laxative should be dispensed if the dose prescribed is for 1 tablespoonful qid for 3 days?
3. . If the flow rate for normal saline (NS) is 30 drops per minute over 6 hours, how many milliliters of NS would the patient receive (assuming 18 gtts/ml)?
PLEASE HELP IF YOU CAN

1)
Use a proportion to find the number of mg, then convert to mcg.

Convert to micrograms: 1 mg = 1,000 mcg

2)1 tablespoonful qid (four times a day) for 3 days (4 X 3) = 12 tablespoonsful.
1 Tablespoonful = 15 ml approximately. Perhaps your PDR has the exact conversion factor for this but I think it's more like 14.7868 ml per tbsp.
12 tbsp = 180 ml approximately.
12 tbsp = 177.4412 ml more precisely.
3) Flow rate of 30 drops per minute over 6 hours (30 drops/min)(60 min/hr)(6 hrs) = 10,800 drops at 18 gtts/ml (18 drops/ml) = 600 ml.
