| Question | Answer |
|---|---|
| it's illegal to compound | commercially available products |
| a counter balance is a 2-pan balance used for | larger weights (up to 5kg), has a sensitivity requiremetn in the range of +/- 100mg, & are used for bulk materials (not for compounding) |
| ingredients & weights should be | placed on paper in C3 rx balancing |
| a C3 balance is also known as | a "class a" balance |
| weighing paper is for avoiding contact between the | tray & the ingredients |
| weighing paper is also called | powder paper |
| a digital electronic balance has a | single pan, it's easy to use, it's more accurate & expensive ($2,500+) |
| digital electronic analytical balances have a capacity of | 100g & sensitivity as low as +/- 1mg |
| the balances have polished brass with noncorrosive coating with | both metric & apothecary weights |
| forceps are used to grasp small objects to avoid | hands natural oils which can change weight of objects |
| hard rubber spatulas are often used for | corrosive material |
| a plate is made of | ground glass that mixes compounds |
| parchment paper can be | used if nonabsorbent |
| mortar & pestle can be made of | corse grained porcelain or "wedwood" used for pulverizing |
| smooth glass mortar & pestles are for | liquids & semisolids |
| a compounding slab is also called | an "ointment slab" |
| cylinders, pipettes, & beakers can be | glass or polypropylene |
| a conical cylinders is | wide topped & narrow based or cylindrical |
| conicals are | metric & apothecary |
| cylinders are calibrated in | metric units (more accurate) |
| beakers are less accurate than cylinders and measure | large liquid volumes when precision isn't necessary |
| pipettes measure liquids less than | 1.5mL |
| hoods, masks, & gowns are used when | preparing powders |
| there are capsule | machines & tablet presses |
| autoclaves sterilize | instruments |
| incubators culture | products |
| minimum compounding requirements are | hairnets, lab coats, & gloves |
| hazard requirements are | goggles, masks, double gowns, & eyewashe stations |
| usp chpt. 795 specifies to wash hands first, to dispose | gloves after, & keep food out of the staging area |
| electronical balances are | prefered, must be perfectly leveled, warmed & calibrated up for use, locked when not used, & cleaned afterwards |
| C3 rx balance is enough for | occasional use |
| measurement error is | expected sometimes |
| allowances are made for | some %age errors |
| %age error formula is | error amount/desired amountX100 |
| error %age is an acceptable range of | variations over/under measurement |
| must work within an | acceptable error range |
| use the smallest device that holds the required | volume & measure at eye level at the bottom of the meniscus |
| the meniscus is the | moon-shaped/concave liquid appearance in a cylinder |
| to compound, techs should get a | master control record, ingredients, equipment, & mixing directions |
| most have uninterrupted | adequate time |
| master control record or pharmacists can give | the best mixing techniques |
| comminution is the process of | reducing things to fine particles |
| trituration rubs or grinds things to get | fine particles like with mortar and pestle |
