Hello everyone I am taking a pharmacology class for college and I was wondering if anyone could help me with these questions? I'm having trouble solving them it is due soon.
1. Order: Administer 500 mg of vancomycin IV piggy back in 60 minutes q12 hours. The medication is available in 100 mL of NS. How many mL/hour will be given?
2. The Order: give PenG 400,000 units IM bid. The PenG is available as 250,000 U/mL. How many mL will be given each dose?
3. Order: Give 500mg of Keflex po q6 hr. Available: 250 mg tablets. How many tablets will the patient receive in a 24-hour period?
4.Order: Give Naprosyn suspension 0.275 g po. Available: Naprosyn 125mg/5 mL. How many mL will be given?
reminds me of tossing multiple ingredients into a big cauldron and hoping that a good soup/stew turns out.
Our community college has a math tutoring center and when students attended there to get help, they were told to do Dimensional Analysis. Us oldies had a hard time with that method and we would find students doing 1/2 dimensional analysis and another method. . The policy kept coming from above that we all had to do dimensional analysis. Us Faculty who were responsible for the content were kind of passive aggressive. We chose a textbook and created learning modules that showed all 3 methods. It was so much easier heading the students off from going to the Math center for help by holding our own review sessions. Scores went up and we could see what students were doing wrong.
I went to school before the push for dimensional analysis. Recently I really tried to understand it but just couldn't do it consistently. I too, am old school and use D/H x's vehicle.
It wasn't used in my program either, and it took some time for me to learn it. And, while I don't always use it in my practice, I do use it when working with students or new nurses as, in my opinion, D/H×V can be problematic with some complex infusions.

These are very basic calculations requiring only simple conversions. If you're having difficulty with this level of question you should seek out remedial training/tutoring. You will be taking clinical math tests throughout your program so it's best to obtain a grasp of the concepts (I.e. dimensional analysis, D/H x V, etc.) now before the pressure is really on!
for #4 I got the answer 0.275g, my mom tried to help me with that one but she didn't write down the work for it or she didn't understand either so she just wrote it down? whenever she handed to paper to me and also cause her teacher sent her that answer (we take the same class but different teacher) , and for the others we didn't get any work done math isn't our best subject.
Think about the answer you got.
Your question was
4.Order: Give Naprosyn suspension 0.275 g po. Available: Naprosyn 125mg/5 mL. How many mL will be given?
You were asked how many mL and your answer is in grams.
That should be a big red flag to you that your answer is incorrect.
When working these problems pay attention to the units of measure and provide the answer in the units requested. mL is measuring volume. Grams is measuring weight.
Fortunately you're late to the game, but tell me if you hadn't been, what has the OP learned from you giving her the "answers"? Can she now safely calculate drug dosages? Does she know where to look to figure out how to do it? Have you supported a future nurse in an on-going way or given her any tools to be successful? Has she practiced critical thinking in any way? What's worse is some of your answers aren't even correct.

I'd rather do multiple little steps to get to my answers. I am GOOD.
