Hi! I'm currently a nursing student trying to figure out a dilutent/dosage calculation problem and just need help in the right direction.
Order: Penicillin G potassium 400,000 units IM every 4 hours.
Available: Penicillin G 5,000,000 units/mL.
Directions state: Add 8.2 mL dilutent to provide 500,000 units/mL.
How many milliliters will you administer?
I'm assuming 8.2mL is added so instead of 5,000,000 units/mL, it will be 500,000 units/mL. I did the dosage calculation equation (400,000/500,000 * 1mL) which gave me 0.8mL. Is this correct? Help is appreciated.
Yes, 0.8 mL is correct.
And thank you for showing us ykur anawer, and what you did to get it.
