---|---|
pyrogens | chemicals produced by microorganisms that can be pyretic (fever) reactions in patients |
isotonic | when a solution has an osmolarity equivalent to that of blood |
hypertonic | when a solution has a greater osmolarity than that of blood |
hypotonic | when a solution has a lesser osmolarity than that of blood |
TPN solution | complex solutions with two base solutions (amino acids and dextrose) and additional micro-nutrients |
HEPA | a high efficiency particulate air filter |
laminar flow | continuous movement at a uniform rate in one direction |
horizontal flow hood | a laminar flow hood where the air crosses the work area in a horizontal direction |
vertical flow hood | a laminar flow hood where the air crosses the work area in a vertical direction |
coring | when a needle damages the rubber closure of a parenteral container causing fragments of the closure to fall into the container and contaminate its contents |
hub | the part of the needle that attaches to the syringe |
shaft | the stem of the needle the provides the overall length of the needle |

USP <795> | Regulation from USP/NF pertaining to the non-sterile compounding of formulations. |
biological Laminar Flow Hood | used for hazardous drugs |
Laminar Flow hood | nothing must interrupt the flow of air between Hepa filter and object |
Flow hoods | Needs to be turned on 30 minutes prior to use to produce an ultra clean enviroment |
