Guest guest Posted January 29, 2003 Report Share Posted January 29, 2003 Dear , a spansule has ben addressed here on this site for the November exam. I just can not find the old post rightnow. A spansule gets its name from a capsule that spans over time. Okay so this is like a Contact capsule. Inside are several beads of drug. each are coated with a special coating. Some beads may be of a different coating or of a different size or color. The varying beads would 'open up' to release the drug at specific intervals, so that the drugs in sustained released. Example: Capsule carries large blue beads, medium red beads and small yellow beads. Small yellow beads open up now and get absorbed as if you took one pill to last 8 hours. Sometime near the 8th hour the medium red beads open up (or get broken down)and get absorbed as if you took the second pill to last 8 hours. Some time near the 16th hour the large blue pill opens up (gets digested / broken down) gets absorbed as if you took the last pill to last another 8 hours. Therefore the beads of drug spanned over 24 hours. he patient ionly has top take the capsule or spansule one time a day, opposed to one cap three times a day.

Guest guest Posted January 29, 2003 Report Share Posted January 29, 2003 Dear , MgSo4 50% means 50gm in 100 ml of solution. Threfore by ratio/proportion 50gm/100ml = 2 gm / Xml = 2 x 100 / 50 = 4ml I think you mkay have found and error in the book. But I am interested in knowing how you got 6ml and the book got 2.4 ml. Let me know, Jeanetta > > > sorry " sherry072252 " > > But I have another math question, I am trying to > figure this out, to pass the PTCE, so I can find a job. > > 1) " What amount of 50% magnesium sulfate solution > should be injected to prepare an > IV bag containing 2 g MgSO4?

Guest guest Posted February 14, 2003 Report Share Posted February 14, 2003 Hi - While this particular problem is fairly easy to " do in your head " if you're used to this stuff, I still like to use the percent solution formula to double check my answers. As you can see the question provides you with all the info you need to set up the equation--- Remember, tot.vol/% available= X/% of desired conc. In this case: 1000ml/7%= X/3.5% X=500ml You'd do the same thing with the dextrose: 1000ml/30%= X/15% x=500ml You could also use this method to eliminate some of the choices 1000ml/10%= X/3.5% X=350ml. Your two volume choices for Amino Acid 10% are 5ooml or 300ml--so you can elimate those two choices.

Guest guest Posted February 15, 2003 Report Share Posted February 15, 2003 Dear Dora, Thanks for posting your answer. Due to BDay and Valentines Day I took a break. So I was not available to answer this. Dora didn't we have this same problem before and we both answered it from different angels? Perhaps in my private tutoring. Any way can you do me a favor and run a quick check in the " Discucssions Tutorials " and maybe some archives?! I tried but I may have missed it. In the response that I gave I used allegation method AND the V1xC1 = V2 x C2 Method. In addtion you and another person (I think Della) also gave great answers and methodology. So I thought that I had placed it the Discussion Tutorials, but i can not find it. if you need any more on this let us know.

Guest guest Posted March 12, 2004 Report Share Posted March 12, 2004 This answer is open to professional debate but for purposes of the answer choices you have been given the answer is 2. 30 mg 1 grain = 60 mg 1/2 grain = 30 mg 1/4 grain = 15 mg 26. How much codeine is contained in a tablet comprised of acetaminophen with 1/2 grain codeine? 1. 15 mg 2. 30 mg 3. 50 mg 4. 60 mg Lynch-Brunozzi Quote Link to comment Share on other sites More sharing options...
