Sterile Compounding Study Guide for Quiz
| Term | Definition |
|---|---|
| Intracellular Spaces | Water is primarily found within the cells of the body. (inside cells) |
| Interstitial Spaces | Water found in the spaces between the cells |
| Extracellular Spaces | Water found outside of the cells |
| Homeostasis | Maintaining a proper fluid and electrolyte balance within the body |
| Dehydration | The amount of water entering the body is less than the amount of water leaving the body |
| PH value | The degree of alkalinity or acidity of the fluid measured on a scale from zero. |
| PH acid | less than 7.0 |
| PH alkaline | more than 7.0 |
| PH neutral | equal to 7.0 |
| Human PH blood value | 7.4 |
| (D5W, LR, NS) PH Value | 3.5-6.2 |
| Osmolarity | Measure of the number of milliosmoles of solute per liter of solution. (mOsmo/L) |
| Osmotic Pressure | Pressure required to maintain equilibrium within the cells. |
| Osmolality | Measure of the number of milliosmoles of solute per kilogram of solvent (mOsm/kg) |
| Isoomotic | Same osmotic pressure as human blood plasma and dissolves particles. |
| Tonicity | The response of cells or tissues to surrounding fluid |
| Hypertonic Conditions | Cell shrivels (shrinks), contains a greater number of dissolved particles than human blood particles. (for long-term IV nutrition) |
| Hypotonic Conditions | Cell bursts (explodes + swells) contains fewer dissolved particles than human blood plasma. (1/4 NS, for patients who experience diuresis, more urine output than normal) |
| Isotonic Conditions | Cell healthy/normal, contains a number of dissolves particles equivalent to human blood plasma. Provides hydration and electrolyte replacement for hospitalized patients. (normal IVs) |
| LVPs | Large-Volume Preparations, sterile parenteral solutions of at least 100ML, but generally 250ML or greater. |
| Continuous Infusion | Typically consists of a base solution with additives such as electrolytes or multi-vitamins, used for: replacement infusion, hydration replacement, and maintenance infusion. |
| Drip | A solution is comprised an IV base solution with medication that has been injected into the solution for the treatment of a specific condition. (heparin, aminophylline, dopamine, debutamine, nitroglycerin, nitroprusiside, amiodarone, and insulin) titrated |
| Milking Technique | Add positive pressure to the closed system by injecting into the vial an amount of air that is equal to, or slightly les than, the volume of liquid to be withdrawn from the vial. |
| Vial | Closed-system container |
