Q & A
What is the main topic of the video?
-The main topic of the video is drug calculation, specifically focusing on the unit cancellation method for solving drug-related math problems.
Why is it important to be familiar with conversion tables when doing drug calculations?
-Being familiar with conversion tables is crucial because it allows you to accurately translate different units of measurement into each other, which is essential for correct drug dosage calculations.
What is the unit cancellation method?
-The unit cancellation method is a technique used in drug calculations where you arrange the given values in a way that allows you to cancel out unnecessary units, leaving you with the unit of the answer that the problem is asking for.
How do you convert kilograms to pounds?
-To convert kilograms to pounds, you multiply the number of kilograms by 2.2, since 1 kilogram is equal to 2.2 pounds.
How many milliliters are in 1.2 liters?
-There are 1200 milliliters in 1.2 liters, as 1 liter is equal to 1000 milliliters.
If a vial contains 2 milligrams of morphine sulfate per 1 ml, how much ml would you administer for a 1 milligram dose?
-You would administer 0.5 ml, because the problem can be set up as 2 milligrams equals 1 ml, so 1 milligram is half of that, which is 0.5 ml.
How many tablets would you give if the order is for 25 milligrams of medication and you have 25,000 micrograms per tablet?
-You would give 1 tablet, as the problem can be solved by converting 25 milligrams to 25,000 micrograms and then setting up the calculation as 25,000 micrograms per tablet equals 1 tablet.
What is the ml administration rate for a drug if the patient weighs 65 kilograms and the doctor ordered 0.3 milligram per kilogram, with a vial labeled as 1 ml per 10 milligrams?
-The ml administration rate would be approximately 2 ml, calculated by multiplying 0.3 mg/kg by 65 kg, then dividing by 10 mg/ml, and rounding to the nearest tenth of a milliliter.
How many hours will it take to infuse 1000 ml of IV fluid at a rate of 125 ml per hour?
-It will take 8 hours to infuse 1000 ml of IV fluid at a rate of 125 ml per hour, calculated by dividing 1000 ml by 125 ml/hour.
What rate in ml per hour should the IV pump be set at for an insulin drip of 20 units per hour, with 250 ml of NS and 100 units of insulin on hand?
-The IV pump should be set at a rate of 50 ml per hour, calculated by multiplying 20 units/hour by 250 ml, then dividing by 100 units.
How many drops per minute should be delivered for a patient to receive 500 ml of NS over 4 hours with a drop factor of 10 drops per ml?
-The patient should receive 21 drops per minute, calculated by converting hours to minutes, then dividing 500 ml by the total minutes (240), and then dividing by the drop factor of 10 drops/ml.
What advice does the speaker give for mastering drug calculations?
-The speaker advises that the key to mastering drug calculations is practice, encouraging viewers to solve a lot of math problems using the techniques learned in the video.
