Introduction

Medical assistants are often responsible for calculating dosage and administration of medications. This practice test will help you identify areas where you need to brush up on your dosage calculations skills.

The basics of dosage calculations

Dosage calculations are an important part of the medical assistant’s job. This portion of the medical assistant practice test will assess your knowledge of dosage calculations. You will be given questions that you must answer in a set amount of time. Be sure to read each question carefully and do not take too much time on any one question. The goal is to answer as many questions as possible in the allotted time.

There are three basic types of problems that you may encounter on the medical assistant practice test:
1) Finding the solution,
2) Interpreting the information, and
3) Identifying the best course of action.

To solve a “finding the solution” problem, you will need to use one or more of the following steps:
1) Convert all units to a common unit,
2) Use division or multiplication to reduce or increase by whole numbers, 3) Cross multiply when two ratios are given, 4) Find a proportion when an equivalent is known, 5) Use addition or subtraction when finding percents above or below 100%, or 6) Estimate when you cannot solve exactly.

To solve an “interpreting information” problem, you will need to use your knowledge of medical terminology and abbreviations. You may also need to know how to read a dosage label or prescription orders. Be sure that you understand all of the information that is given before attempting to answer the question.

Practice problems

This Medical Assistant dosage calculations practice test will help you prepare for the Certified Medical Assistant (CMA) exam. The CMA exam is a computer-based test that is divided into two parts. Part one is knowledge-based and consists of multiple-choice questions. Part two is skills-based and includes a hands-on component.

The skills-based portion of the CMA exam tests your ability to perform medical assistant tasks, such as taking vital signs, administering injections, and performing EKGs. One of the skills tested on the CMA exam is dosage calculations. This practice test will help you brush up on your math skills and learn how to calculate dosages correctly.

There are three types of problems on this practice test:
-Simple arithmetic problems that require you to add, subtract, multiply, or divide
-Problems that require you to convert units
-Problems that require you to solve for an unknown quantity

You will have 30 minutes to complete this practice test. Be sure to read each question carefully and select the best answer from the choices given.

More practice problems

Here are a few more practice problems to help you prepare for your medical assistant dosage calculations test. Remember to always work through the steps slowly and carefully to ensure you get the correct answer.

1. You are asked to administer 2 mL of a 0.5% lidocaine solution. How many mL will you give the patient?
2. You need to prepare 500 mL of a 0.1% solution of potassium chloride from a 5% stock solution. How much of the 5% stock solution will you need?
3. You are asked to dispense 4 pills for a patient. The prescription says “dispense as 1 tablet every 8 hours” but the bottle only contains 30 tablets. How many days will this supply last?
4 You have been asked to prepare 500 mL of a 0.5% dextrose and 0.45% saline solution from two solutions: a 5% dextrose solution and a 0.9% saline solution. How much of each solution will you need?

even more practice problems

Now that you have reviewed the basic concepts of dosage calculations, let’s do some more practice problems. These problems will be a little more challenging, so take your time and use the process of elimination to arrive at the correct answer.

1. The doctor has ordered 0.625 mg of digoxin for a patient. The bottle is labelled 125 mcg/5 mL. How many mL will you administer?
2. The doctor has ordered 40 mg of furosemide for a patient. The bottle is labelled 250 mg/5 mL. How many mL will you administer?
3. You are administering an IV drip of D5W to a patient at the rate of 125 mL/hour. The bottle is labelled 1000 mL/250 mL D5W. How long will it take to administer the entire bag?
4. The doctor has ordered 1 gram of cefazolin for a patient. The vial is labelled 50 mg/mL . How many mL will you administer?

Tips and tricks

Here are some tips and tricks to help you master medical dosage calculations.

Practice, practice, practice! Get a bunch of different types of problems and work through them until you’re confident you can do them quickly and accurately.

Don’t just focus on the answer – pay attention to how the problem is structured and what information is given. This will help you understand how to approach similar problems in the future.

Try to work out the answer in your head before you start doing any calculations. This will help you catch any mistakes you might make in your math.

Make sure you understand the units involved in the problem. This is particularly important with medical dosage calculations, where getting the units wrong can have serious consequences.

If you’re having trouble with a particular type of problem, look for examples of that type of problem online or in textbooks. Once you’ve understood how to do one example, it will be easier to do others like it.
