What do you do if the Flow Rate calculation involves fractions such as ¼ of an hour or 0.5 litres? Find out how this is managed mathematically. This is the fundamental formula for all IV problems. What does Flow Rate = Volume/time mean? Flow rate is determined by the volume of liquid that passes by (into a patient) within a certain time period. Bigger patients need a bigger dose! Learn what this unit means and when and how to use it. How do you deal with a unit like mg/kg? Milligrams per kilogram means that you must give a certain amount (mgs) of a drug for each kilogram of the patient’s body mass. Find out how to convert dosages between larger and smaller units. If you express your dosage in a smaller unit, the number must get bigger, and vice versa. How do you convert between units? Nurses use units that begin with milli and micro a lot. Converting between large and small units.Learn how you could solve these problems before applying the formula. This is the simple principle behind the Volume Required formula. If you need double the dose of medication, you need to give double the volume of the liquid that it is dissolved in and so on. Using proportions with liquid solutions.This tutorial introduces the Volume Required formula and shows you how to apply it to a problem. What is volume required formula? This formula tells us how much liquid-form medication we need to give a patient, considering the strength they need and the source that it comes from. After each tutorial, test your knowledge with the interactive activities. The following tutorials are an introduction to basic drug calculations for nursing.
