drug calculations[can you see if my answers are correct?]
- 0Sep 29, '13 by AmandaSchroederHey guys, I am doing a packet for my next semester professor and she wants us to come in knowing how to do this. What that means to me is I will not find out the correct answers like I can in my book b/c she wrote this on word herself. So I was wondering if you could see if you came up with similar answers. I was actually confused on how to set up a few of the questions so they very well might be wrong, if you feel like showing me how you set yours up it would be very beneficial to me! And any tips or how to make this super simple in my head(maybe its so simple its confusing me, IDK)!
1. For a child, the M.D. has ordered Polycillin 35 mg q 6 h. The Polycillin comes in a
Suspension: 50 mg per 5 ml. How much do you give?
2. Pre-op order: Atropine gr 1/150 IM. The atropine is available for injection labeled 0.4 mg/ml. How much do you inject?
3. Another pre-op order: Demerol 15 mg and Scopolamine 0.3 mg IM. Available: Demerol 50 mg/ml, Scopolamine 1/200 gr/ml. How much of each drug will you give? Can you mix them in one syringe? <-----Can someone explain this part?
4. Order: Penicillin 1000 mg P.O. available Penicillin Tabs. 0.25 Gm. How may tabs do you give?
5. Order: ASA 600 mg P.O. You have ASA gr 5 tabs. How many do you give?
6. Order: Theophylline 100 mg liquid. You have 80 mg/15ml. How many mlís will you give?
I got 18.75 mL's
7. Order: Morphine Sulfate liquid 10 mg q4hours pm. You have 20 mg/ml. How much will you give?
0.5 mLs Q4h PM
8. Order reads: Give KCL 10 meq. Liquid. You have 20meq/15ml. How much will you give?
I am not confident in any of my setups of the formulas but this one extremly stumped me more than usual and my answer I got was....
I set it up this way--any easier ways??
EX: Morphine Sulfate liquid 10 mg q4hours pm. You have 20 mg/ml. How much will you give?
----------- x 1 mL = (after cancelling out I get 0.5 mL

Quote from AmandaSchroederYou are being presented several problems in this scenario: when you work this type of problem it works best to identify the component questions. What specific questions are you being asked?Another pre-op order: Demerol 15 mg and Scopolamine 0.3 mg IM. Available: Demerol 50 mg/ml, Scopolamine 1/200 gr/ml. How much of each drug will you give? Can you mix them in one syringe? <-----Can someone explain this part?

- 1Oct 1, '13 by GrnTeaYour calculation answers are all correct.
You can find information on compatibility in a drug book or online, or call my favorite resource on drugs in general, the pharmacist.
If two meds are compatible, you can, and often do, mix them in one syringe. The way you do it is to draw up one into the syringe, then draw up the second into it, and change the needle before you give it to the patient because by now the needle has lost all its slippery surface and may have a little burr on the end of the bevel, making for a more uncomfortable injection.
(In the old days when we had multi-dose vials, you would also change the needle between meds to avoid contaminating the second vial with med from the first, but no longer an issue.)
- 1Oct 7, '13 by loriangel14 GuideQuote from audie88We learned "doc over stock". What was ordered over hwat you have.When calculating meds , we learned a simple way called "Do Da" Its dose ordered/dose available x amount
For example the doctor orders cavedilol 10 mg tabs available you have 5mg tablets per 1 tablet....you would calculate 10/5 x 1 which would be 2 tablets. I hope this helps
