A new session of each course starts monthly. If enrolling in a series of two or
more courses, please be sure to space the start date for each course at least two
All courses run for six weeks, with a two-week grace period at the end. Two lessons
are released each week for the six-week duration of the course. You do not have
to be present when lessons are released. You will have access to all lessons until
the course ends. However, the interactive discussion area that accompanies each
lesson will automatically close two weeks after the lesson is released. As such,
we strongly recommend that you complete each lesson within two weeks of its release.
The final exam will be released on the same day as the last lesson. Once the final
exam has been released, you will have two weeks to complete all of your course work,
including the final exam.
Has it been a while since you multiplied fractions? Converted decimals to percents? Used exponents or powers of 10? Today we’ll review these math topics—and more—because they’re what medical professionals commonly need to use. You’ll get lots of practice in this lesson, so if you’re a little rusty, don’t worry—you’ll be back up to speed in no time!
Do you remember how to convert centimeters to inches and pounds to kilograms? We’ll cover the metric system along with the U.S. customary system of measurement. You’ll become a master at making conversions within and between the two systems, and you’ll learn how medical professionals use these measurements every day.
“Amoxicillin 500 mg PO b.i.d.” What does this medication order mean? In Lesson 3, we’ll unlock some of the jargon and abbreviations these orders use. You’ll interpret ratios, determine rates, and set up and solve proportions—all of which will help you as you determine medication dosages and make other medical calculations.
Can you convert liters per hour to milliliters per minute? Do you know how to calculate body surface area to use in a pediatric dosage calculation? You’ll learn these skills and more in Lesson 4. We’ll cover the basics of dimensional analysis and then use it to solve problems that are more complex. We’ll also focus on several key formulas that medical professionals use. And you’ll learn different ways to solve the same problem, so you can choose the method that’s easiest and fastest for you!
What are the three forms of oral medications? Do you know how to calculate the dose of an oral liquid medication based on body weight? And what does “mEq” mean? In Lesson 5, we’ll apply what you’ve learned in previous lessons as you master new skills. You’ll calculate doses of oral medications in solid and liquid form. You’ll also learn to dose oral medications based on body weight and body surface area.
Can you interpret the percent strength of a solution and use it in a dosage calculation? Do you know how to prepare dilutions from stock solutions? In Lesson 6, you’ll learn about solution strengths as ratios and percentages, and you’ll practice the calculations necessary to prepare solutions.
Do you know how to reconstitute a powdered medication? Can you calculate dosages for medications that you have to inject? In Lesson 7, you’ll learn to formulate doses of parenteral medications. You’ll do calculations for liquid parenteral medications measured in milliliters and in units.
Have you ever calculated the flow rate for an intravenous infusion? What's an enteral infusion? In Lesson 8, you'll learn the basics of intravenous and enteral solutions and infusions. You'll learn to calculate the flow rates for both kinds of infusions. You'll also figure out how long it will take a solution to infuse.
What do IVP and IVPB mean? How do you calculate an IV flow rate based on a patient's body weight or body surface area? In Lesson 9, you'll learn how medical professionals give medications intravenously, and you'll practice calculating flow rates in different circumstances.
Should you round dosing calculations up or down for pediatric patients? What are the best dosing practices for children and older adults? In Lesson 10, you'll learn about special dosing concerns for your younger and older patients. You'll calculate doses for pediatric and geriatric patients using body weight and body surface area. We'll also cover additional age-specific issues, like daily fluid maintenance and dosing of patients with reduced kidney function.
How do you measure what's typical or average in a data set? And what's a standard deviation? In Lesson 11, you'll learn basic statistics that you can apply in the medical field. You'll see how to use statistics to summarize a data set. You'll also understand how people use data and statistics to make decisions, improve quality, and develop best practices in medicine.
How do you collect good data? What's a p-value, and what does p < 0.05 mean? In Lesson 12, you'll work with examples from the medical field as you calculate and interpret probabilities. You'll also learn about ways to collect data. When you've finished this lesson, it'll be easier for you to understand and evaluate research results.
This course was great! Very interesting. I am glad I took it.
It?s a very good course for busy people. It was very helpful, boosted my confidence. My attitude towards math has changed because of this course. Thank you.
A very well done course!
To help me pass the Pharmacy Tech exam I took this course to refresh what I learned in a continuing education class. This course did that and then some. I am looking for a job and I am excited to get started in a new career. Thank you!
This was a good class and I liked the way the instructor seemed very real, personable; almost as if we were in an actual classroom.
Medical math was exactly what I was looking for. Each problem was explained in detail. I copied the chapters and I could practice, practice, practice, until I knew it perfectly.
This was an excellent course and I will definitely recommend it to students who are interested in pharmacy tech, paramedic, or nursing.
I felt that the instructor did a very thorough job explaining mathematical concepts and formulae that are present in health care jobs that require math. My confidence soared during this course, as I have always been intimidated by any kind of math beyond addition, subtraction, multiplication and division. I would recommend this course to anyone who wants to improve their math skills both at work and outside of work. Thank you, Ben!
I loved this course and I think the teacher did an awesome job. I liked the class because you can take the quizzes as many times as you like, you can print all your stuff out and use it to help you learn the material. I liked the professor because he answered the questions quickly. The discussion area was nice because it allowed the students and the professor to help you. I would recommend this course to anyone that is going into nursing or anyone that is working in the medical field.
I wanted to say thank you for your great class. I think this is a great course for any one going into the medical field. It helped to build my confidence and introduced me to some concepts I wasn't expecting, I learned many new things. I wasn't sure what to expect going into the class, but I feel it was worth the time, effort and money to participate and take the class. The saying: you don't know what you don't know helps to summarize what I thought at the end of the class. It opened my eyes to how much more I should learn about dosage calculations and all of the considerations that go into determining dosages for different types of medications and different types of patients.
A great variety of subject matter that I feel was relevant was covered as thoroughly as possible in the amount of time given, great organization of information, thank you for offering this class.
