The solution was prepared by adding morphine to dextrose 5… This problem can be solved using a variety of methods, including setting up a fractional equation, ratio-proportion, and DA. Proportional calculations involve using an available drug concentration and a desired final drug amount … Applicants who score less than Know the patient's weight in kg if your calculation is weight based. To determine the number of weakest parts (ie, dextrose 5%) that will be needed, the difference between Box A and Box C needs to be found (see Figure 3). Calculate MT's IBW and the correct acyclovir dosing regimen. 3 parts of (B) + 27 parts of water = 30 parts (C) total. Occasionally in pharmacy practice, a weaker solution must be made from a more concentrated solution such as a concentrated stock solution. Adjusted body weight (ABW) is often used when dosing select medications in patients who are considered obese.3 The definition or cutoff for obesity varies by institution, although patients who have body fat contents greater than 25% to 30% of their actual body weight are generally considered obese.9 A common definition of extreme or morbid obesity is a weight that is greater than 200% of IBW.9 Following are 2 examples of ABW calculations9: ABW = IBW + (0.4)(actual body weight – IBW), ABW = IBW + (0.3)(actual body weight – IBW).

Dilutions are an important topic in pharmacy calculations. BSA is generally considered the most accurate method used to calculate drug doses because it is a mathematical function of height and weight.3 BSA is most often used when dosing chemotherapy drugs and can be calculated by the inches and pounds method or the metric formula that utilizes centimeters and kilograms. The volume of ingredients present in the two volumes need to be added together. Note: the symbol (√) represents the square root function. Found inside – Page 37If two tablespoonfuls of a 10% w/v povidone–iodine solution were diluted to 1 quart with purified water, what would be the ratio strength of the dilution? Multiply the final desired volume by the dilution factor to determine the needed volume of the stock solution. Found insideIntended for use in an introductory pharmacy technician calculations course, this unique book addresses not only calculations that technicians will encounter in retail, but also those necessary for compounding, IV, industry and areas where ... Step 2: If the 1000mL contains 10mL of the substance, then the 50mL must also have contained 10mL of the substance . • perform calculations involving the dilution and mixing of solutions and suspensions. Let the number of milliliters of 1 in 80 solution be y and let the amount of ingredient in 500mL of 0.02% solution be x. Chapter 19 - Percentage Strength. Pharmaceutical Journal 260: 768. Setting up proportional sets: We find that x is 80. This is a possible solution because the desired concentration (1.5%) is between the available strengths (1% and 2.5%). Instead of seeing a compound written as mg/mL or g/mL, it is expressed as a percent like the intravenous fluid, dextrose 5%. We can set up the following proportional set: We need to convert mg to g and hence ‘a’ = 2mg.

Sometimes it is called “Tic-Tac-Toe” math. To ensure safe, effective treatment for patients, a weight-based dosing method is often used for populations such as pediatric or elderly patients, and it is in the prescribing information for many medications.7 In healthcare, clinicians may also use body size descriptors such as ideal body weight (IBW), adjusted body weight (ABW), or body surface area (BSA) to dose drugs in patients at the extremes of body size to increase effectiveness and reduce toxicity.3,8 Specific dosing recommendations for medications can be found in printed references, a myriad of software applications, and product package inserts, which are typically referenced as milligrams per kilograms (mg/kg)—not milligrams per pound (mg/lb).
