We don’t care about the 3 hours, the IVPB, the normal saline, or even the name of the drug! The question is essentially asking you to convert 2.5 g to milligrams.īelow is a table of different abbreviations so you can identify various units of measurement. So what are they asking for in this question? They are asking for how many milligrams the patient will receive. Your patient has 2.5 grams of Vancomycin in 500 ml normal saline to be administered IVPB over three hours ordered, how many milligrams total will this patient receive? It is important to keep your mind focused on specifically what is asked and what unit you are being asked to answer in. Nursing math tests are like many of your other exams in nursing school: sometimes there are multiple distractions in the question that you have to weed through to get down to the meat of it. Onward! Med Math Step 1: What are they asking? By understanding both, you will be best equipped to safely administer medications as a registered nurse.Īlright, now let’s work through each specific step of the Med Math Mind Map. Understanding the dosage calculations, drip rates, unit conversions, and so forth is one thing, but understanding the pharmacokinetics is another. We created a mind map to help you navigate through these steps easier, especially if you’re a visual person.īefore I dive into each specific step, I just want to remind you to check out our Med Master course, which is the perfect compliment to this post about med math. We created an amazing outline/mindmap to help you navigate your math questions! Here’s a quick rundown of our 6 steps to nursing med math success! PART ONE: 6 Steps to Nursing Med Math Success Keep in mind, that while we will go over quite a bit here, there are a few things that you’ll just simply have to memorize.
We are going to walk you through some of the important basic concepts to be aware of, as well as some tips and tricks to make things a bit easier.

Learning how to rock nursing math can be challenging, but it doesn’t have to be gastric-ulcer producing. And the “nurse” that teaches the course is a pharmacist. Our Nursing Pharmacology Course was developed by a team of nurses who went through nursing school, passed pharmacology, and are/were successful bedside providers. Med math for nurses and pharmacology absolutely go hand-in-hand, and we know this connection is so important that we created a course to help you not only get through pharmacology but truly understand it. We also had to take and pass the ever-painful pharmacology course as well. We had to take and pass many math classes throughout nursing school. It’s stressful to have that in your mind while taking these tests… but what may be even more stressful is knowing that you’re calculating medications for patients and if you’re way off, it could result in bad news bears for your patient.Īt, we completely feel your pain. We had to get at least a 96% or we failed the nursing math test, and if we did that… we failed the course. When I was in school (2007-2010), we had a nursing math test each semester. How many mg should a child weighing 8 lbs receive? 8lb x 1 kg/2.2lb x 1.5 mg/1 kg = 5.In this post, we are going to provide you with EVERYTHING you need to simplify med math. How many tablets per dose? 1 g x 1000 mg/1 g x 1 tablet/125 mg = 8 tabletsĨ tablets/ 4 doses = 2 tablets/dose MD order: Compazine 10 mg PO TIDĭrug label: Compazine 5 mg/ 5 mL 10 mg x 5 mL/5mg = 10 mL per dose The recommended does of Demerol for a preoperative IM injection is 1.5 mg/kg. 0.1g x 1000 mg/ 1 g x 5 ml/50 mg = 10 mLġ0 mL x 1 tsp/5 mL = 2 tsp Amoxicilin 1 g is prescribed in four equally divided doses. Calculate the amount that the patient should receive in tsp. How many mL equal the ordered dose? 0.035 mg x 1mL/0.05 mg = 0.7 mL Order: Symmetrel syrup 0.1 g PO BID. How many tsp? 375 mg x 5 mL/125 mg x 1 tsp/5 mL = 3 tsp Order: Digoxin 0.035 mg PO BID.
