Guest guest Posted March 2, 2003 Report Share Posted March 2, 2003 Hi Deedonwho, First you need to figure out how many mL of the suspension contains 100 mg of Dilantin. I don't think the math problem set-up will print properly here but I'll try. 125 mg = 100 mg _______ _________ 5mL x mL You cross multiply (100 x 5) = (125x) 500 = 125 x x = 4 The answer is 4 mL. So for this part of the problem, you now know that to dose Dilantin Susp in 100 mg doses you need 4 ml for each dose. But the doctor's order is for Dilantin 100 mg #30 tid. You still need to do the math to dose the medication three times a day for 10 days. To complete the problem, you need to multiply 4ml X 3 (times a day) X 10 (length of treatment) = 120 mL. You need to dispense Dilantin 125 mg/mL 4mL TID x 10 days = 120mL. ________________________________________________________________________________\ ________________________ Please help..... How would I break this down to get the answer? A physician orders 125mg/5ml dilantin suspension to replace an order reading, 'DILANTIN 100 MG, DISPENSE: #30, SIG: 1 TID " WHAT QUANTITY OF SUSPENSION SHOULD BE DISPENSED? Could you please show steps... Thanks, Deedomwho Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 2, 2003 Report Share Posted March 2, 2003 Dear Deedumbwho, and ALL, Thank you for answering this problem. You did a great job. I will attempt to reso the set up so that it will " line up " on this site. To do so I will have to use what I call " spacers " . 125 mg------------100 mg ________----=----___________ 5 mL--------------- " X " mL Cross multiply 100 x 5 =125 x " X " 500 = 125 x " X " 500 _____ = " X " 125 4 = " X " Alternatively, you may wish to change the order in which you solve: You may also wish to look at the overall amount that you will need to pour out into a bottle first (the total amount dispensed and to be sold). 100mg x 3 x 10 = 3000 mg total 125mg------------3000 mg ______----=-----___________ 5 ml-------------- " X " ml Cross multilpy: 5 x 3000 mg ____________ = " X " 125mg 120 ml total to be dispensed Follow up with the conversion of 100mg, the individual dose to ml for labeling purposes. (Method outlined by or above). However one can just divide then by the number of total doses for this perscription: 120ml divided by 30 doses = 4ml 120ml total dispensed 4 ml per 100mg dose Either way is fine. Iusually teach the method laid out by called Ratio/Porportion Method. However the good old 'olgical method " works well also. Since labeling is usually done first, before pouring, finding out the indivdual dose in " X " ml is very convenient, on the job. However a third alternative method- You may wish to use a more " logical " approach or good old fashion math: 100mg x 3 x 10 = 3000mg 3000mg divided by 125mg/5ml = Xml total dispensed 3000mg x 5ml/125mg = 120ml total dispensed Total dispensed divided by the # of doses 120 ml / 30 doses = 4ml/dose I can not print a 'divided' sign. So I have to use the word divided. Again I do recommend use of the Ratio/Proportion Method. There are many other calculations that you will have to use it with. Therefore practice using it with the math that you understand. Once you understand the math 'logically' then set it up with R/P method for practice. You will be surprised how easy it is and how well you will understand it. This question adn the response or replies will be placed in the " Discussion Tutorial Files " . Thank you both for your Q & A. Deedumbwho, You have helped many by just asking. And has helped by answering.

Guest guest Posted March 3, 2003 Report Share Posted March 3, 2003 Thank you so much, Jeanetta & . I understand this so much better now. I am sorry for not posting a THANK YOU earlier, but my keyboard has taken a dive (which will be replaced today). I can not type certain things like numbers. But once again....A BIG THANK YOU (can't do exclaimation mark).

Guest guest Posted March 3, 2003 Report Share Posted March 3, 2003 Dear DeeDomWho, You aremost welcome. I have placed this math problem in the Discussion Tutorial. I am sure it will help someone else inteh near future. I also corrected your name, as both and I had misspelled it. Thank you again.

Guest guest Posted May 14, 2007 Report Share Posted May 14, 2007 Hi, My son's sed rate and c-reactive protein was even higher. We see a infectious disease doctor. Those two test will come back elevated during an episode. I know its hard to stay calm, but please don't panic! Dena Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 14, 2007 Report Share Posted May 14, 2007 Actually those rates are not that high compared to a lot of children (probably most) here...hope that calms things down. Trish Jenn <jnt522@...> wrote: Hi, I'm freaking out here. My daughter is in the process of getting testing done to see if she has the PAPFD. The doctor just called and said her SED rate was high (60) and her C-Reactive Protein was high (14.4)...They are sending us to an infectious disease specialist. Has anyone else been referred to an infectious disease dr??? Please let me know. I'm worried sick. Jenn--Mom to Hannah 2 years old. --------------------------------- The fish are biting.
