Hello Everyone,
I am having problems answering two questions regarding Penicillin Reconstitution and my professor is not answering my email. Can you please explain the problem and your reasoning behind the answer/mls used?
1. Order: Penicillin 700,000 units IM q4h.
The label on a five million unit vial contains the following reconstitution guide:
18.2 ml solution to make 250,000 units/ml
8.2 ml solution to make 500,000 units/ml
3.2 ml solution to make 1,000,000 units/ml
Circle the number of mls you will use to reconstitute the penicillin.
After mixing with this amount, how many mls should you withdraw from the vial in order to give and infant 700,000 units?
Answer: 700,000/1,000,000 x 1 ml = 0.7ml
2. Order: Penicillin 450,000 units IM q4h.
You find a 5 million unit vial with the following reconstitution guide:
18.2 ml solution to make 250,000 units/ml
8.2 ml solution to make 500,000 units/ml
3.2 ml solution to make 1,000,000 units/ml
After reconstituting, how many mls should you withdraw in order to give 450,000 units?
Answer: Use the 3.2 ml solution
450,000 units/ 1,000,000 units x 1 ml = 0.45 ml
I am seriously struggling with these questions and I appreciate any assistance received.
