Study Notes
-
To convert pounds (lbs) to kilograms (kgs), divide the weight in pounds by 2.2.
-
To convert micrograms (mcg) to milligrams (mg), divide the amount in micrograms by 1000.
-
To convert milligrams (mg) to grams (g), divide the amount in milligrams by 1000.
-
To convert ounces to milliliters (mL), multiply the number of ounces by 30.
Oral Medication Dosage Calculation
-
For tablets, know the desired dose, the available dose (tablet strength), and use the formula: (Desired Dose / Available Dose) x Quantity to find the number of tablets needed.
-
For liquid oral medications, make sure the units are consistent, and use the formula: (Desired Dose / Available Dose) x Volume to find the volume in mL needed.
Injection Dosage Calculation
-
Ensure the units for the desired dose and available concentration are the same.
-
Use the formula: (Desired Dose / Available Concentration) x Volume to calculate the required volume for injection in mL.
IV Flow Rate Calculation
- To calculate IV flow rates in mL per hour, use the formula: (Total Volume to Infuse / Total Time in Hours) = Flow Rate in mL/hour.
Intake Calculation
- To calculate total intake in mL, convert all oral and IV volumes to mL and sum them up, considering all sources of fluid intake.
