Intravenous Therapy
| Term | Definition |
|---|---|
| The 3 main purposes of IV therapy | Maintaining or providing daily body fluid and electrolytes because of inability to ingest fluids and nutrients by mouth |
| The 3 main purposes of IV therapy | Replacing abnormal or excessive loss of fluids and electrolytes |
| The 3 main purposes of IV therapy | Providing an avenue for IV administration of medications |
| IV push means | the medication is injected directly into the vein using a needle and syringe |
| 2 advantages of IV push | an immediate therapeutic blood level and instantaneous effects of the drug |
| intermittent infusion device | prn lock/saline lock |
| Precipitate | forms when one of the agents in a solution separates from the solvent and becomes a solid, insoluble product. It may or may not be visible, look cloudy, hazy, or like fine floating crystals |
| Hypotonic solution | lower osmolarity than body fluids, which simply means there is less solute dissolved in the water, making the concentration of the dissolved particles less than that of the body fluids |
| Isotonic solution | fluid that contains an amount of solute that produces a concentration of dissolved particles equal to that of the intracellular and extracellular fluids of the human body. |
| Isotonic solution | there will be no movement of fluids across the semipermeable membranes of the blood vessels or cellular membranes |
| Hypotonic solution | will cause shifting of body fluids out of the intravascular space and into the interstitial spaces and then eventually into the intracellular spaces, rehydrating the cells |
| Hypotonic solution | Out of the vessel, intO the cell |
| Hypotonic | 1/2 NS 0.45% NaCl |
| Hypotonic | 1/3 NS 0.33% NaCl |
| 0.45% NaCl (1/2 NS) | Water replacement, hypertonic dehydration |
| 0.33% NaCl (1/3 NS) | Free water replacement to aid kidneys in elimination of wastes |
| Isotonic | D5W (5% Dextrose in water) |
| D5W | Provide some calories for energy, provide free water |
| Isotonic | NS 0.9% NaCl |
| 0.9% NaCl NS | the ONLY fluid used to initiate and discontinue blood transfusion, replacement of nutrients and electrolytes when no fluid shift is desired |
| Isotonic | Lactated Ringer's (LR) |
| Lactated Ringers LR | most similar to el4ectrolytes content of the blood so used for fluid replacement in all types of dehydration and fluid volume deficits |
| Hypertonic | 5% Dextrose in 0.45% sodium chloride D5 1/2 NS |
| Hypertonic | 5% Dextrose with 0.9% normal saline D5NS |
| Hypertonic | 10% to 50% Dextrose D10W, D20W, D50W |
| Hypertonic | 3% to 5% sodium chloride 3% NaCl, 5% NaCl |
