Ch 16 Fluid and Chemical Balance
Term | Definition |
---|---|
Active transport | process of chemical distribution that requires an energy source. |
Air embolism | bubble of air in the vascular system. |
Anions | electrolytes with a negative charge. |
Blood substitutes | fluids that when transfused carry and distribute oxygen to cells, tissues, and organs; also known as oxygen therapeutics. |
Cations | electrolytes with a positive charge. |
Circulatory overload | severely compromised heart function. |
Colloids | undissolved protein substances. |
Colloid solutions | water and molecules of suspended substances, such as blood cells, and blood products such as albumin. |
Colloidal osmotic pressure | force for attracting water. |
Crystalloid solution | water and other uniformly dissolved crystals, such as salt and sugar. |
Dehydration | fluid deficit in both extracellular and intracellular compartments. |
Drop factor | number of drops per milliliter in intravenous tubing. |
Edema | excessive fluid in tissue. |
Electrochemical neutrality | balance of cations with anions. |
Electrolytes | chemical compounds, such as sodium and chloride, that are dissolved, absorbed, and distributed in body fluid and possess an electrical charge. |
Emulsion | mixture of two liquids, one of which is insoluble in the other. |
Extracellular fluid | fluid outside cells. |
Facilitated diffusion | process in which certain dissolved substances require the assistance of a carrier molecule to pass from one side of a semipermeable membrane to the other. |
Filtration | process that regulates the movement of water and substances from a compartment where the pressure is high to one where the pressure is lower. |
Fluid imbalance | condition in which the body's water is not in proper volume or location in the body. |
Hydrostatic pressure | pressure exerted against a membrane. |
Hypertonic solution | solution that is more concentrated than body fluid. |
Hypervolemia | higher-than-normal volume of water in the intravascular fluid compartment. |
Hypoalbuminemia | deficit of albumin in the blood. |
Hypotonic solution | one that contains fewer dissolved substances that normally found in plasma. |
Hypovolemia | low volume in the extracellular fluid compartments. |
Infiltration | escape of intravenous fluid into the tissue. |
Infusion device | electric or battery-operated machine that regulates and monitors the administration of IV solutions. |
Infusion pump | device that uses pressure to infuse solutions. |
intake and output | record of a client's fluid intake and fluid loss over a 24hour period. |
Intermittent venous access device | sealed chamber that provides a means for administering intravenous medications or solutions on a periodic basis. |
Interstitial fluid | fluid in tissue space between and around cells. |
Intracellular fluid | fluid inside cells. |
Intravascular fluid | watery plasma, or serum, portion of blood. |
Intravenous fluids | solutions infused into a client's vein. |
Ions | substances that carry either a positive or negative electrical charge. |
Isotonic solution | solution that contains the same concentration of dissolved substances as normally found in plasma. |
Needleless systems | equipment that eliminates the need for needles. |
Nonelectrolytes | chemical compounds that remain bound together when dissolved in solution. |
Osmosis | process that regulates the distribution of water. |
Oxygen therapeutics | fluids that when transfused carry and distribute oxygen to cells, tissues and organs; also known as blood substitutes. |
Parenteral nutrition | nutrients, such as proteins, carbs, fats, vitamins, minerals and trace element, which are administered intravenously. |
Passive diffusion | Physiologic process in which dissolved substances, such as electrolytes and gases, move from an area of higher concentration to one of lower concentration through a semipermeable membrane. |
Peripheral parenteral nutrition | isotonic or hypotonic intravenous nutrient solution instilled in a vein from the heart. |
Phlebitis | inflammation of a vein. |
Port | sealed opening. |
Pulmonary embolus | blood clot that travels to the lung. |
Third-spacing | movement of intravascular fluid to nonvascular fluid compartments, where it becomes trapped and useless. |
Thrombus formation | development of a stationary blood clot. |
Total parenteral nutrition | hypertonic solution of nutrients designed to meet almost all the caloric and nutritional needs of clients. |
Venipuncture | accessing the venous system by piercing a vein with a needle. |
Volumetric controller | electronic infusion device that instills intravenous solutions by gravity. |
