Here, we try to avoid using proportional sets as a mechanism. The reason is two-fold. First, that using proportional sets tends to add more steps to solve the question, thereby increasing the risk of error. Second, using a more logical approach with limited steps decreases the risk of error. Below, we review the logical approach that we recommend. That said, we would always recommend that you adopt the approach that works best for you. The more questions you practice, the better and more refined your knowledge and understanding of math questions.
The dose available to the pharmacy technician is mg per capsule. In this case, the physician prescribed 0. These are inconsistent unit and must therefore be corrected before we can continue. Next step — we must know the total dose of drug prescribed to the patient.
This means having a detailed knowledge of prescription abbreviations. This means the patient needs to take milligrams four times during the day — or 2, milligrams per day. The dose available in the pharmacy is mg per capsule — meaning that the patient needs to take 2 of these capsules 4 times per day. The physician prescribed Cleocin mg IM q12h x 4d. First, are units the same? Yes — Cleocin is available as mg and the pharmacy has a generic form the medicine available at mg.
What dose, in milligrams to the nearest whole number , should be given to a patient who weighs lbs when the drug literature states that the dose should be 0.
In this case, the answer is no. We have lbs and we also have 4kg. Because the question asks to answer in milligrams, we must convert 4 kilograms to lbs — that way all units are the same.
Now, we know that the patient weighs lbs and that, for each 8. Therefore, if we divide lbs by 8. To answer this question, we simply need to know the volume of medicine to be dispensed. Sometimes when answering PTCB sample questions, you need to know when to ignore details in the question. Often, not all details need to be used. Bear this tip in mind as you continue through this math study guide. The drug is only available in mg tablets.
At first, this question might seem difficult. You, the pharmacy technician, are asked to prepare a mL solution for a patient. In every 5mL of that solution, there must be mg of drug. In other words, if every 5mL of the mL solution has mg, then there must be 18,mg of drug in a mL solution:.
If there is 5mg in 5mL, then there must be 20mg in 20mL! Now, we know that we need 18,mg. The question asks us how many mg tablets are needed. Author s : William A.

This math refresher. Probably, you would go to the library or a bookstore. The first option takes a lot of time, and it is not very convenient because not all books can be taken home. The second option is bookstores. However, it is not cheap buying books today. The most convenient way to find the book you need is to get it in an electronic format online.
When you get a book online, you can either print it or read it directly from one of your electronic devices. This is very convenient and cost effective. With the advent of the internet, our life has become easier. We do not go to libraries because most of the books can be found online.
