nursing 212 exam - fluid and electrolytes Questions With
Complete Solutions
adrenal gland function in homeostasis
help the body conserve sodium, save chloride and water, and
excrete potassium
pituitary gland function in homeostasis
stores and releases ADH (anti-diuretic hormone)
thyroid gland function in homeostasis
increases the blood flow in the body and increases renal
circulation
nervous system function in homeostasis
inhibits and stimulates mechanisms influencing fluid balance
parathyroid hormone function in homeostasis
regulate the level of calcium in ECF
GI tract function in homeostasis
absorbs water and nutrients that enter the body through this
route
hypervolemia
deficiency in amount of water and electrolytes in extracellular
fluid with near normal water/electrolytes
- too MUCH fluid volume in vessel
, hypovolemia
fluid loss from the vessel
- too LITTLE volume in the vessel
dehydration
decreased volume of water and electrolyte change
- fluid loss from the body or tissues (CELL)
overhydration
too MUCH fluid in the body or tissues (CELL)
third space fluid shift
distributional shift of body fluids into potential body spaces
edema: excessive ECF accumulates in tissue spaces
ascites: in the peritoneal cavity - indicates liver disease, typically
fluid pulled from vessel (very low BP)
risk factors of hypovolemia
GI losses, skin, renal losses, third spacing, altered PO intake,
bleeding (BP decreases, HR increases to compensate for low
blood volume)
assessment of hypovolemia
- tachy/thready pulse
- hypotension/orthostatic hypotension
- thirst/dry mucous membranes
