| 100 degrees celcius | 212 degrees fahrenheit |
| Arabic number system | 1, 1/2, 0.5 or 50% |
| Roman number system | I,V,L,C,D |
| Positional notation | a system used in roman numerals whereby the position of the numeral signifies its mathematical value |
| Denominator | number below the bar |
| Numerator | Number above the bar |
| Conversions | changing one unit of measure into another so that both amounts remain equal |
| Equation | a mathematical statement in which two terms are equal |
| Liquids ML-OZ formula | x fl oz= (total prescribed ml)/(ml/fl oz conversion rate) |
| Filling Capsule Script formula | x (caps needed)= (caps per dose)x(dose per day)x (days) |
| IV solution formula | x (ml of KCl solution)=mEq KCl needed/mEq KCl per ml |
| ratio formula | a/b=c/d |
| proportion equation | x tabs/days= x tabs/ days |
| liquid prescription formula | x ml= mg times ml/mg |
| word equation | amount needed= dose amount x doses day x number of days |
| mixture dosing formula | x ml= ml mix needed times ml/ml mix have |
| IV flow rate formula | x ml= # min times ml/min |
| Variable | an unknown number in a mathematical equation |
| flow rate | the rate in ml/hr or ml/min at which a solution is administered to a patient; also known as rate of administration |
| volume % formula | x volume wanted/ want % = volume prescribed/ have % |
| Dose formula | Dose= ordered/have x quantity |
| 1 gram | 100 ml |
| concentration | the strength of a solution as measured by weight to volume or volume to volume of the substance being measured |
| TPNs | totl parenteral solutions or hyperalimentaion |
| Percent solution formula | x ml/ % = ml/ % |
| qs ad | the quantity needed to make a prescribed amount |
| Milliequivalent | MeQ= the unit of measure for electrolytes in a solution |
| Valence | the number of positive or negative charges on an ion |
| Electrolytes | substances which conduct an electrical current and are found in the bodys blood tissue fluids and cells. |
| Commonly used in electrolyte solutions | Salts and saline solutions |
| NaCl | Sodium Chloride |
| MgSO4 | Magnesium sulfate |
| KCl | potassium chloride |
| K acetate | potassium acetate |
| Ca Gluconate | Calcium gluconate |
| Na Acetate | Sodium Acetate |
| In order to calculate mEq for an electrolyte, the atomic number and weight must first be known. Then | the weight is divided by the valence |
| To figure out a TPN order the amounts on the left | are the ordered TPN amounts |
| To figure out a TPN order the amounts on the right | are the amounts on hand |
| TPN formula after amounts are figured | water needed= 1000ml minus other ingredients |
| Alligation | a way to solve problems asociated with mixing prepartations of two different strengths of the same ingredient to obtain a strength in between the starting preperation |
| Finding power volume formula | FV (final volume) = D (dilutent) = PV (powder volume) |
| finding powder new product (NP) | NP=D+PV |
| Clarks rule formula to lower adult doses to be safe for children | wight of child/ 150lb x adult dose = child dose |
| Body surface Area Formula | Childs BSA times Adult dose/ average adult BSA (1.73m squared) |
| 1 kg | 2.2lbs |
| infant dose formula | one dose= (amount of drug) times ( number of kg of infant weight) |
| BSA | Body surface area: a measure used for dosage that is calculated from the height and weight of a person and measured in square meters |
| Nomogram | a chart showing relationships between measurements |
| Professional Fee for prescription less than $20 | $4 |
| Professional fee for prescriptions between $20.01-$50 | $5 |
| Professional fee for prescriptions between $50.01- and higher | $6 |
| U & C | Usual and customary is the lowest price charged if a patient pays cash on that day for that drug, |
| Selling price formula | AWP (average wholesale price)+ Professional Fee = price of prescription |
| Gross profit | the difference between the selling price and the aquisition cost GP=SP-AC can be expressed as a % |
| Net Profit | the difference between the selling price of the prescription and the sum of all costs associated with filling the prescription NP=GP-DF (dispensing fee) |
| Conditions for using ratio and proportion | three of the four values must be known, numerators must have the same units, and denominators must have the same units |
| Steps for solving proportion problems | define the variable and correct ratios, set up the proportion equation, establish the x equation, solve for x, express solution in correct units |
| name 2 types of measurement not used frequently in pharmacies anymore | avoirdupois (lbs, oz's and grains) and Apothecary (gal, qts, pts, fl oz,fl dr,minim) |
