How do I calculate mL per hour?
Use the following equations: flow rate (mL/hr) = total volume (mL) ÷ infusion time (hr) infusion time (hr) = total volume (mL) ÷ flow rate (mL/hr)
How do you calculate patient fluid?
Maintenance Fluid Rate is calculated based on weight.
- 4 mL / kg / hour for the first 10kg of body mass.
- 2 mL / kg / hour for the second 10kg of body mass (11kg – 20kg)
- 1 mL / kg / hour for any kilogram of body mass above 20kg (> 20kg)
What kind of math is used in pharmacy technician?
There are many math concepts that are used in this career role such as addition and subtraction, fractions, determining percentages, weights, and even measurements. It is vital that you are skilled in math computation and have a strong background in math to ensure patients are receiving the correct dosage of medicine.
How is pharmacy concentration calculated?
To express the value as a percentage, we need to convert the number of milligrams in 100mL to grams in 100mL: 900mg = 0.9g There is 0.9g of sodium chloride in 100mL of solution, thus the percentage is 0.9% w/v.
Can you use calculator in pharmacy?
Are you allowed to use a calculator when taking the PTCB exam? Yes, you are. The exam proctor will give you a standard calculator to use during the exam.
How do you calculate new concentration after mixing?
Hi Sheerien, In general when your are mixing two different concentrations together first calculate number of moles for each solution (n=CV ,V-in liter) then add them together it will be total moles,then concentration of mixture will be = total moles / total volume(liter).
How do you add two different concentrations together?
- Calculating the strength of a mixture of two different concentrations.
- Example 1.
- Method.
- Step 1: Calculate the amount of drug A in each concentration.
- Step 2: Add the two amounts together.
- Step 3: Add the two volumes together.
- Step 4: Put total amount over total volume.

What is volume in math?
In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.
How to do pharmacy calculations?
Step 1: For this calculation, simply multiply the rate by the amount of time, making sure that the units cancel to leave you with volume. One of the most important areas of study for a pharmacy technician is pharmacy calculations.
How do you calculate the volume of a stock solution?
2000 mL (final volume of the compound) – 300 mL (volume of stock solution) = 1700 mL of water Thus, 300 mL of the 0.4% stock solution and 1700 mL of water (solvent) are required to make 2000 mL, or 2 L, of 0.06% solution.
How do you calculate volume to dilute a solution?
This formula can be used to calculate the volume of solvent required to make a diluted solution. For example, to dilute a 50% w/v stock solution to make 200 mL of a 5% w/v solution, c1 = 50, c 2 = 5, and v2 = 200.
How much volume is needed to prepare a solution?
The number of total parts and the number of parts for each component have been found yet this is not the end of the calculations necessary to prepare this solution. The parts must be converted into a measurable amount based on the total volume required. In this case end volume should be 500 mL.
