As long as you keep gtt/ml and gtt/min straight the rest is just math. The only things that makes it more complicated are fractions, decimals and rounding up to the nearest drop. This example seemed very easy, right? Well, it really is just that easy. I.V.drip rate calculation Calculation of infusion times Continuous heparin infusion calculation and Critical care cafoulations (using an infusion pump or infusion device) including calculating the mUhour rate, the dose per minute or per hour, and the dose based on infusion rate. 120mL/Hr ÷ 60(min/Hr) = 2mL/min We arrived at 2mL/min The Infusion set device delivers 10 gtt/ml, Now, simply take the amount of ml/min and multiply it by the gtt/ml. systems and drug calculations/preparations essential to successful nursing practice. The amount available is haloperidol 1 mg/tablet. You have on hand diazepam (Valium) 5 mg/mL. How should you prepare the correct dose 3. An order reads furosemide (Lasix) 40 mg IV push. How should you prepare the correct dose 2. : The patient is prescribed: 720ml of mixture over 6 hours 720mL ÷ 6 Hrs = 120mL/Hr determine how much per Minute. Math For Nurses: A Pocket Guide to Dosage Calculations and Drug. Med Math practice questions 5.0 (2 reviews) A nurse is preparing to administer haloperidol (Haldol) 2 mg PO q12h. You need to administer prochlorperazine (Compazine) 10 mg IM to a nauseated patient. Let's use an example similar to the one on the IV Infusion devices are calibrated to deliver so many Drops per Milliliter.Ī nurse will set the device to dispense so many drops per minute in order to achieve the proper ml/min. It is very important to never confuse the two. Drops per minute can be adjusted on the device. This is NOT to be confused with Drops per Minute (gtt/min). Find out how this is done.IV Infusion sets are pre-calibrated to how many drops per ml(gtt/ml) of a solution they administer to the patient. This time we are converting not only the volumes, (drops and mls) but the units for time as well. How do you convert IV flow rates? In the previous video, we looked at converting between millilitres (ml) and drops.
