Math is often a source of great frustration for people, but did you know that nurses use math every single day to determine how much solution to draw up into a syringe or to decide whether they need to split a tablet in order to properly dose the patient or to figure out how many drops the IV should run at for each minute. Nursing students love the opportunity to do all these complex tasks, but before the student can properly provide the right medication to the right patient at the right time we must know exactly how much to give.

Pharmacology I will help you learn, step by step, the process used by nurses to determine the right dose. Welcome to Pharmacology I.
