Example
ORDER: 10 mg of famotidine for a patient with severe renal dysfunction. The drug is available premixed as 20 mg in 50 mL. How many mL would you give the patient?
- What is the dose ordered? 10 mg
- What is the standard dose available? 20 mg
- What is the volume for the standard dose? 50 mL
ANSWER:
- If a 10 mg dose has been ordered, and the standard dose available is 20 mg per 50 mL, then administer 25 mL of the standard drug IV push.
IV Dosage Calculator: Push
What is the dose ordered? ng / µg / mcg / mg / g / kg / gr
What is the standard dose available? ng / µg / mcg / mg / g / kg / gr
What is the volume for the standard dose? cc / mL / dL / L / minim
Calculate
If a dose has been ordered, and the standard dose available is per , then administer of the standard drug IV push.
Note: we are using the 65 mg = 1 gr and the 15 minim = 1 mL conversion equivalents.
Sample Problem 1
ORDER: 40 mg of furosemide. The drug is available premixed as 10 mg in 1 mL. How many mL would you give the patient?
ANSWER:
4 mL
Sample Problem 2
ORDER: 1 mg of epinephrine. The drug is available at 0.5 mg per mL. How many mL would you give the patient?
ANSWER:
2 mL
((Dose Ordered × Standard Volume) / Standard Dose Available) × Conversion Factor = Volume to be Administered
- ((DO × SV) / SDA) × CF = ADMVOL
- DO = Dose Ordered
- SV = Standard Volume
- SDA = Standard Dose Available
- CF = Conversion Factor = (UDO / USDA)
- UDO = Units Dose Ordered
- USDA = Units Standard Dose Available
- ADMVOL = Volume to be Administered
