Examples:
- Convert 500 mg to grams.
- Convert 2 liters to milliliters.
2. Calculating Dosages
Determining the correct medication dose based on prescribed amounts and patient factors.
Examples:
- Calculate the dose in mg for a patient when the order is 250 mg, but the medication comes in 125 mg tablets.
3. IV Flow Rate Calculations
Determining the infusion rate in mL/hr or drops/min.
Examples:
- How many mL/hr should be infused to deliver 1,000 mL over 8 hours?
4. Pediatric and Body Weight Calculations
Using patient weight to calculate medication doses.
Examples:
- Dose = (Patient weight in kg) × (Dose per kg).
5. Percentages and Ratios
Calculating medication concentrations or dilutions.
Examples:
- Find the percentage strength of a solution.
Sample Medical Math Practice Test with Solutions
Below is a set of practice questions with detailed solutions to illustrate typical problems encountered.
Question 1: Unit Conversion
Convert 750 milligrams (mg) to grams (g).
Solution:
- Knowing that 1 g = 1000 mg,
- So, 750 mg ÷ 1000 = 0.75 g.
Answer: 0.75 grams
Question 2: Calculating Medication Dosage
A doctor orders 500 mg of amoxicillin. The medication is supplied as 250 mg tablets. How many tablets should the patient take?
Solution:
- Number of tablets = Total dose ÷ Dose per tablet
- = 500 mg ÷ 250 mg = 2 tablets
Answer: 2 tablets
Question 3: IV Flow Rate Calculation
An order calls for infusing 1,200 mL of fluid over 12 hours. What should be the flow rate in mL/hr?
Solution:
- Flow rate = Total volume ÷ Time (hours)
- = 1,200 mL ÷ 12 hours = 100 mL/hr
Answer: 100 mL/hr
Question 4: Pediatric Dose Calculation
A child weighing 15 kg is prescribed amoxicillin at a dose of 20 mg/kg/day, divided into 3 doses. How much medication should be given per dose?
Solution:
- Total daily dose = 15 kg × 20 mg/kg = 300 mg
- Dose per administration = 300 mg ÷ 3 = 100 mg
Answer: 100 mg per dose
Question 5: Calculating Percent Concentration
A solution contains 50 grams of a drug in 500 mL of solution. What is the percentage concentration?
Solution:
- Percentage concentration = (grams of solute ÷ mL of solution) × 100
- = (50 g ÷ 500 mL) × 100 = 10%
Answer: 10% solution

Sample Medical Math Practice Question with Solution
Question:
A patient requires an infusion of 500 mL of normal saline over 4 hours. What should be the flow rate in mL/hr?
Solution:
Step 1: Understand what is asked.
Flow rate = total volume / total time
Step 2: Convert the time to hours if necessary.
Given: 4 hours (already in hours)
Step 3: Calculate flow rate.
Flow rate = 500 mL / 4 hours = 125 mL/hr
Answer: The infusion should be set at 125 mL/hr.
Additional notes:
If the problem involved minutes, you'd convert hours to minutes (e.g., 4 hours = 240 minutes) and then calculate accordingly.
