Question | Answer |
Positional notation | a system used in roman numerals whereby the position of the numeral signifies its mathematical value. |
ss | 1/2 |
I or i. | 1 |
V or v | 5 |
X or x | 10 |
L or l | 50 |
C or c | 100 |
D or d | 500 |
M or m | 1000 |
xxx=30 | or 10+ 10 + 10 |
dc= 600 | or 500 + 100 |
lxvi= 66 | or 50+ 10 +5 + 1 |
ix=9 | or 1 subtracted from10 |
xxxix= 39 | 0r 30+ (1 subtracted from 10) |
xc=90 | or 10 subtracted from 100 |
denominator | the bottom or right number in a fraction |
numerator | the top or left number in a fraction |
every fraction can be turned into a decimal by dividing. | ex: 7/8=0.875 or 2/10=0.2 |
how do you find a fraction's reciprocal? | flip it. 1/2 will become 2/1 |
how would you find a whole number reciprocal? | put a one over it. ex: 5=1/5 |
least common denominator | smallest possible denominator for an equivalent fractio so that two fractions can be added or subtracted and have to same denominator |
how do you find the least common denominator? | 4/15+1/5= 4x5(numerator)5x15(denominator on both fractions) 15x1(second denominator). 75 denominator reduce when done |
Conversions | changing one unit of measure into another so that both amounts remain equal |
Variable | an unknown value in a mathematical equation |
Concentration | the strength of a solution as measured by the weight-t0-volume or volume-to -volume measured |
milliequivalent (mEq) | the unit of measure for electrolytes in a solution |
qs ad | the quantity to make a prescribed amount |
total parenteral nutrition (TPN) | administration of all units intravenously, also known as hyper-alimentation |
Valence | the number of positive or negative charges on an ion |
Body Surface area (bsa) | a measure used for dosage that is calculated from the height and weight of a person measured in square meters |
nonogram | a chart showing relationships between measurements |
Clarks Rule (for child dose) | weight of child/150lb x adult dose= child dose |
Young's rule (for child dose) | age of child/ age + 12 x adult dose= child dose |
Body surface area (child dose) | child bsa x adult dose/ average adult bsa= child dose |
How do you calculate gross profit? | Gross profit = Selling price - Acquisition cost |
How do you calculate net profit? | Net Profit = Gross profit - Dispensing fee |
What is the equation for final volume? | Final Volume (FV)= Diluent (D) + Powder Volume (PV) |
How would you find powder volume? | PV = FV - D |
You have a prescription for 100mg of a drug that you have in 250mg/5ml. How many ml do you need? | 250mg/5ml = 50mg/ml. multiply to get100mg (so in this case, by two) and do the same for ml. 2ml |
what equation would be best for mEq? | xml/#mEq=#ml/#mEq, cross multiply mEq, divide by mEq. get ml |
A 70% HCl solution has the strength of 35mEQ/ml. How many ml are needed to prepare 50mEq? | 35meQ/ml = 50mEq/ml 50/35= 1.428 round up 1.43 ml |
