Pharmacy Proc II
Pharm Proc II YBI Chapter Eight Terms
| Question | Answer |
|---|---|
| additive | A drug that is added to a parenteral solution. |
| admixture | The resulting solution when a drug is added to a parenteral solution. |
| ampules | Sealed glass containers with an elongated neck that must be snapped off. |
| anhydrous | Without water molecules. |
| aseptic techniques | Methods that maintain the sterile condition of products. |
| bevel | An angled surface at the tip of a needle. |
| compounded sterile preparation (CSP) | A compounded sterile parenteral dosage form that will be parenterally administered. |
| 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. |
| depth filter | A filter that can filter solutions being drawn into or expelled from a syringe, but not both ways in the same procedure. |
| equivalent weight | A drug's molecular weight divided by its valence; a common measure of electrolyte concentration. |
| final filter | A filter that filters solution immediately before it enters a patient's vein. |
| Flashball | Flexible rubber tubing near the needle adapter on an administration set; used to determine if the needle is properly placed in the veins. |
| flow rate | The rate at which solution is administered to the patient. |
| gauge | A measurement with needles: the higher the gauge, the smaller the lumen. |
| dialysis | Movement of particles in a solution through permeable membranes. |
| diluent | A solvent that dissolves a freeze-dried powder or dilutes a solution. |
| HEPA filter | A high efficiency particulate air filter. |
| heparin lock | An injection device which uses heparin to keep blood from clotting in the device. |
| horizontal flow hood | A laminar flow hood where the air crosses the work area in a horizontal direction. |
| hub | The part of the needle that attaches to the syringe. |
| hypertonic | When a solution has a greater osmolarity than that of blood. |
| hypotonic | When a solution has a lesser osmolarity than that of blood. |
| ions | molecular particles that carry electric charges. |
| irrigation solution | Large volume splash solutions used druing surgical or urologic procedures to bathe and moisten body tissues. |
| isotonic | When a solution has an osmolarity equivalent to that of blood. |
| laminar flow | Continuous movement at a uniform rate in one direction. |
| lumen | The hollow center of a needle. |
| lyophilized | Freeze-dried. |
| membrane filter | A filter that attaches to a syringe and filters solution through a membrane as the solution is expelled from the syringe. |
| molecular weight | The sum of the atomic weights of a molecule. |
| osmosis | The action in which a drug in a higher concentration solution passes through a permeable membrane to a lower concentration solution. |
| osmotic pressure | A characteristic of a solution determined by the number of dissolved particles in it. |
| peritoneal dialysis solution | A solution placed in and emptied from the peritoneal cavity to remove toxic substances. |
| piggybacks | Small volume solutions added to an LVP. |
| pyrogens | Chemicals produced by microorganisms that can cause pyretic reactions in patients. |
| ready-to-mix | A specially designed minibag where a drug is put into the SVP just prior to administration. |
| shaft | The stem of a needle that provides the overall length of the needle. |
| sharps | Needles, jagged glass or metal objects, or any items that might puncture or cut the skin. |
| total nutrient admixture solution (TNA) | A TPN solution that contains intravenous fat emulsion. |
| total parenteral nutrition solution (TPN) | Complex solutins with two base solutions and additional micronutrients. |
| valence | The number of positive or negative charges on an ion. |
| vertical flow hood | A laminar flow hood where the air crosses the work area in a vertical direction. |
| waters of hydration | Water molecules that attach to drug molecules. |
