The calculation is based on your weight in pounds (lb), and your daily mg dose of medication. Weight in pounds is converted to kilograms
(kg) by dividing by 2.205
. Weight in kg is then divided into the daily mg dose of medication to give the dose calculated as mg/kg/d.
How do you calculate dosages?
- The clinician has 2 mg/mL vials in the automated dispensing unit.
- How many milliliters are needed to arrive at an ordered dose?
What does 20mg kg mean?
The dose on the label is 20 mg/kg or
20 milligram of drug per kilogram of body weight
. The concentration of drug in the bottle is 300 mg/ml.
What does 250mg 5ml mean?
The label reads 250mg /5ml. You would give ____ml(s). 200 ÷ 250 x 5 ml = 4 ml. 2. The order is for 60mg.
How do you calculate medication by weight?
| Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day | Step 3. Convert the mg dose to mL: 1800 mg/dose ÷ 40 mg/mL = 45 mL once daily |

Do you round weight in kg?
When calculating weight-based dosage (i.e., mg/kg or mcg/kg, etc.),
do not round final calculation until the final calculation
. Round only at the end of the calculations.
What is Clark’s rule formula?
Clark’s rule equation is defined as the
weight of the patient in pounds divided by the average standard weight of 150 pounds (68 kg) multiplied by the adult dose of a drug equals the pediatric medication dose
, as is demonstrated below: (Weight* divided by 150 lbs.) x Adult Dose** = Pediatric Dosage.
What is the formula for calculating drip rate?
Drip Rates — is when the infusion volume is calculated into drops. The formula for the Drip Rate:
Drip Rate = Volume (mL) Time (h)
. A patient is ordered to receive 1 000 mL of intravenous fluids to run over 8 hours.
How do I calculate flow rate?
Flow rate is the volume of fluid per unit time flowing past a point through the area A. Here the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The volume of the cylinder is Ad and the average velocity is ̄ ̄ ̄v=d/t v ̄ = d / t so that the flow rate is
Q=Ad/t=A ̄ ̄ ̄v Q = Ad / t = A v ̄
.
How are tablets calculated?
Divide the prescribed dose by the dose
of the tablets that are in stock. Add together the dose of each tablet until they add up to the required dose. Then count up how many tablets have been added together.
What is 125mg in mL?
The strength is 125 mg/5mL. How many milligrams have you dispensed? First, work out how many milligrams of the medicine there are in 1 mL. To do this, divide the stock dose (125 mg) by the volume it comes in (
5 mL
).
How much is 5 mL of liquid?
Also, remember that
1 level teaspoon
equals 5 mL and that 1⁄2 a teaspoon equals 2.5 mL.
How many mg is a mL of medicine?
This means that
50mg
of the drug are dissolved in every 1ml of liquid. So, it follows that 2ml of the solution would contain 100mg of the drug. For drugs in liquid form, prescriptions are usually written in terms of weight (e.g. 1 mg), but the drug is usually by concentration (e.g. mg/ml).
What is rounded to the nearest tenth?
To round a number to the nearest tenth ,
look at the next place value to the right (the hundredths)
. If it’s 4 or less, just remove all the digits to the right. If it’s 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
How do you round tablets?
- Rounding to nearest whole number. If the amount to be administered is greater than 0.5, then round up to the whole number. Example: You have calculated a dose to be 4.7 tablets. …
- Rounding to the nearest tenths place. If the amount to be administered is greater than 0.5, then round up to the tenths place. Example:
Is ML HR a whole number?
For IV fluids being administered by an infusion pump (ml/hr),
the number of ml to be infused each hour is to be expressed as a whole number
. Therefore, you would round to the nearest whole ml.
