Term
 equivalent weight
Definition
 1 g molecular weight (from periodic chart) divided by the total positive valence of the material
Term
 Milliequivalent
Definition
 1/1000 As an equivalent weight. A term used to express the concentration of electrolytes in a solution
Term
 What happens in a true proportion? (ex: 8:16 1:2)
Definition
 in the true proportion, the product and that means equals the product of the extremes. Therefore, when a part of the problem is unknown. Excuse me, substituted for the unknown part of proportion and the equation solved for X
Term
 What are the two inner and the two outer #s in a proportion called? (ex: 8:16 1:2)
Definition
 the two inner numbers (16 and one) are called the means, and the two outer numbers (eight and two) called the extremes.
Term
 Describe the arrow method of performing conversions from a larger unit to a smaller unit in the metric system. (ex: 0.3 g of drug A, supply on hand is 150 mg tablets)
Definition
 1. Write down the order. First, using the units called for (0.3 g)2. Write down the equivalent units (on hand) needed next to the order units (0.3 g equals_MG).3. Place an arrow between the 2 units, with the close part of the arrow pointing toward the smaller unit (g → mg)4. Move the decimal .3 places in the direction the arrow points(0.3g → 3 0 0 therefore 0.3 g = 300 mg = 2 150 mg tablets to fill order
Term
 Describe the arrow method of performing conversions from a smaller unit to a larger unit in the metric system (order is for 300,000 mcg of drug A, and supply on hand is 150 mg tablets)
Definition
 1. Write down the order (300,000 MCG)2. Write down the equivalent units needed next to the order units (300,000, mcg equals __ mg). 3. Place an arrow between the 2 units with the close part of the arrow pointing toward the smaller units (mcg ← mg)4. Move the decimal 3 places in the direction of the arrow points (300 mg ← 300 0 0 0 mcg It would take 2 150 mg (150,000 mcg) tablets to fill the 300,000 mcg order
Term
 what is the formula for dosage calculations?
Definition
 Dose = (Animal's wt x dosage rate)/Concentration of drug
Term
 Dose of most drugs used to treat neoplasms is calc according to the total body surface area of the pt. Body surface area is correlated w/ the wt of the animal. A table is used to convert wt to surface area in square meters
Definition
Term
 Define solutions
Definition
 solutions are mixtures of substances that usually are not chemically combined with each other. Solutions are made up of a dissolving substance called the solvent, and a dissolved substance, called solute
