Pharmacology Clear and Simple Chapter 1-3 Complete Questions and Answers A+ ratios - ANS comparisons between two things proportion - ANS statement saying those two ratios are equal formula - ANS rule prescribing how to calculate a dosage dimensional analysis - ANS method based on the premise that any number can be multiplied by one without changing its value fraction method - ANS uses two equivalent proportions to find the answer drug dose calculation:step 1: - ANS conversion of numbers to the same unit of measurement drug dose calculation: step 2: - ANS using the preferred method, write the problem on paper; check again to confirm that your calculations are correct 4 methods by which to calculate drug dosages for nonparenteral (oral) route of administration: - ANS 1. ratio and proportion method 2. formulation method 3. dimensional analysis 4. fractions nonparenteral - ANS oral drug quantities can be in: - ANS tablets, capsules, milliliters, or another unit, and each label has its own equivalents sample drug label should include 8 things: - ANS 1. brand name (trade) 2. generic name 3: drug strength 4 drug form, route of administration if other than oral, total amount of medication in the container, directions for reconstitution if necessary 5. manufacturer 6. National Drug Code (NDC) 7. expiration date 8. lot number Ratio and proportion method: - ANS uses ratios, which are comparisons between two objects (numbers in this case) like 4 pieces of pepperoni pizza and 3 pieces of cheese pizza are 4:3::8:6 or 4/3 = 8/6. Medication order is for 400 mg. Available medication is 300 mg in 1mL. 300 mg/1mL = 400 mg/?mL Formulation method: - ANS involves stacking units that are the same and multiplying by the unit requested. desired dose: - ANS equals the dosage that has been ordered or ordered dose available dose - ANS the dosage on hand D = ? H = ? Q = ? - ANS D = desired Dose H = on hand or available amount in ordered units Q = quantity in units given dimensional analysis: - ANS uses the ordered amount of a drug to multiply with two equal quantities in different dimensions (units of measurement) to derive the answer dimensional analysis steps: - ANS step 1: write the units of the dose ordered step 2: write the units that are on the label and the unit that you plan to give the patient Mg (ordered) x ____ mL _______________________ = mL (desired) Mg for label (ordered) conversion factor: - ANS formula to change from one unit of measurement to another fraction method: - ANS dosage on hand desired dose ________________ = _______________ dosage unit dose given
