Exam 1; General fluids, general electrolyte disorders w/ s&s Flashcards
Roughly 40% of your body weight can be found where?
Intracellular fluids
Roughly about 5% of your body weight is stored where?
Within the vascular system
15% of your body weight can be found with the fluids in what body cavity?
Interstitial
1/3 of your body’s water can be found where?
Extracellularly
The movement of O2, CO2, Glucose, and electrolytes, as well as iv volume, and temperature regulation are all facilitated by…
Body water
The substance mixed into the solvent; like hemoglobin or NaCl
Solute
The substance that the solute is mixed into…
Solvent
What characterized the movement of solvents?
Movement to an area of less water and less pressure
What characterizes the movement of solutes?
Moves to area of less of itself and less ionic charge.
What solutes are able to cross selectively permeable membranes?
Na+ & Glucose
What is unable to cross a cell membrane?
Colloids
What determines a concentration gradient?
Number of solute particles
What determines the hydrostatic gradient?
Water pressure
What determines the osmotic gradient?
Colloids
What determines an electrical gradient?
Ionic charges
Movement across a capillary membrane requires a balance of 1/2
Arteriolar hydrostatic pressure
Movement across a capillary membrane requires a balance of 1/2
Venular osmotic pressure
Osmotic pressure is equivalent to
blood pressure
What is the term for the number of solute particles per kg of water?
Osmolality (mOsm)
What is the largest determinant of osmotic pressure?
Na+ (Sodium)
What are secondary contributors of osmotic pressure?
Glucose, urea
What is the determinant of toxicity?
Sodium (Na+)
What is the first in the order of solution priorities?
Volume
What comes second in the list of treatment priorities?
pH
