1 Basic Math Refresher
Has it been a while since you multiplied fractions? Converted decimals to percents? Used exponents or powers of 10? This lesson reviews these math topics—and more—because they're what medical professionals commonly need to use. You will get lots of practice in this lesson, so if you're a little rusty, don't worry—you will be back up to speed in no time!
2 Measurement Systems and Conversions
Do you remember how to convert centimeters to inches and pounds to kilograms? This lesson covers both the metric and US customary systems of measurement. You will become a master at making conversions within and between the two systems, and you will learn how medical professionals use these measurements every day.
3 Ratios, Rates, and Proportions
"Amoxicillin 500 mg PO b.i.d." What does this medication order mean? Lesson 3 will unlock some of the jargon and abbreviations these orders use. You will 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.
4 Dimensional Analysis and Formulas
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 will learn these skills and more in Lesson 4. You will learn the basics of dimensional analysis and then use it to solve problems that are more complex. This lesson also focuses on several key formulas that medical professionals use, and you will learn multiple ways to solve problems, so you can choose the method that's easiest and fastest for you!
5 Oral Medications
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, you will apply what you have learned in previous lessons as you master new skills, calculating doses of oral medications in solid and liquid form. You will also learn to dose oral medications based on body weight and body surface area.
6 Solutions and Dilutions
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 will learn about solution strengths as ratios and percentages, and you will practice the calculations necessary to prepare solutions.
7 Parenteral Medications
Do you know how to reconstitute a powdered medication? Can you calculate dosages for medications that you have to inject? In Lesson 7, you will learn to formulate doses of parenteral medications. You will do calculations for liquid parenteral medications measured in milliliters and in units.
8 Intravenous Fluids
Have you ever calculated the flow rate for an intravenous infusion? What's an enteral infusion? In Lesson 8, you will learn the basics of intravenous and enteral solutions and infusions. You will learn to calculate the flow rates for both kinds of infusions. You will also figure out how long it will take a solution to infuse.
9 Intravenous Drug Calculations
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 will learn how medical professionals give medications intravenously, and you will practice calculating flow rates in different circumstances.
10 Pediatric and Geriatric Dosing
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 will learn about special dosing concerns for your younger and older patients. You will calculate doses for pediatric and geriatric patients using body weight and body surface area. This lesson also covers additional age-specific issues, like daily fluid maintenance and dosing of patients with reduced kidney function.
11 Descriptive Statistics
How do you measure what's typical or average in a data set? And what is a standard deviation? In Lesson 11, you will learn basic statistics that you can apply in the medical field. You will see how to use statistics to summarize a data set. You will also understand how people use data and statistics to make decisions, improve quality, and develop best practices in medicine.
12 Probability, Data Collection, and Medical Research
How do you collect good data? What's a p-value, and what does p < 0.05 mean? In Lesson 12, you will work with examples from the medical field as you calculate and interpret probabilities. You will also learn about ways to collect data. When you've finished this lesson, it will be easier for you to understand and evaluate research results.
