Fluid and Electrolyte balance The process of regulating the extracellular fluid volume, body fluid osmolality, and plasma concentration of electrolytes What is fluid? Fluid is water plus the substances dissolved and suspended in it What are the characteristics of Fluid & Electrolyte balance? 1. Volume (amount) 2. Concentration (osmolarity) Intracellular Fluid (ICF) fluid inside cells 63-70% of TBW Water, proteins, electrolytes Extracellular Fluid (ECF) Fluid outside cells 30-37% of TBW Intra...

NSG 120 Quiz 4 Pre Actual Exam questions Correctly Answered | VERIFIED 100% Edema - ANSWER an excessive amount of fluid in the interstitial compartment Dehydration - ANSWER insufficient body fluid resulting from inadequate intake or excessive loss of fluids or a combination of the two Homeostasis - ANSWER maintenance of a relatively constant and favorable environment for the cells Water - ANSWER the medium within which metabolic reactions and other processes take place. Transpo...

How much of the body's water is intracellular? 2/3 How much of the body's water is extracellular? 1/3 Interstitial: 75% Intravascular: 25% Smaller amountsL sweat, urine, transcellular Populations susceptible to dehydration: Pediatric and geriatric Net filtration forces favoring filtration minus forces opposing filtration Aquaporins small pores in cells that allow for water transport across plasma membrane Solute Electrolytes/proteins Solvent Water/plasms Osmolarity Concentration of osmo...

Water ~60% of average healthy adult's weight - total amount affected by gender, body size - transports nutrients, waste products - lubricant, insulator, shock absorber - regulates body temperature Intracellular Fluid (ICF) - fluid within cells - 2/3 of total body fluid in adults - contains solutes: oxygen, electrolytes, glucose Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute -- / -- Full screen Brainpower Read More ICF Cations potassium a...

Fluid and Electrolytes are kept in a narrow range of normal to maintain a complex cell environment. correct answer: Describe the role of fluid and electrolyte balance on homeostasis of the body. intracellular fluid (ICF) correct answer: Approx. 2/3 total body water; found within the cells (cytoplasm, nucleoplasm); primarily water; main electrolytes: K+, PO4- extracellular fluid (ECF). correct answer: approx. 1/3 total body water; found outside the cells (intravascular (blood), interstit...
