, minimum urine output for adult - CORRECT ANSWERS0.5mL/kg/hr

ADH (antidiuretic hormone) - CORRECT ANSWERS- water retainer
- vasoconstrictor (also called Vasopressin)
- produced by hypothalamus
- store and released from posterior pituitary

ADH pathway - CORRECT ANSWERS- hypothalamus senses low blood volumed and
increased serum osmolality

- signal pituitary to release ADH

- ADH causes kidney to retain water

- water retention increases blood volume and decreases serum osmolality

ANP (atrial natriuretic peptide) - CORRECT ANSWERS- cardiac hormone stored in atria
- released when atrial pressure increases

*works opposite of RAAS by decreasing BP and reducing intravascular volume

- important diagnostic marker in CHF

hydrostatic pressure - CORRECT ANSWERS- forces fluids and solutes through the capillary
wall and into the tissue spaces

colloid osmotic pressure - CORRECT ANSWERS- pulling force of albumin in the intravascular
spaces

- pull fluid into vasculature

maintenance fluid therapy - CORRECT ANSWERS- replaces normal ongoing losses of water
and electrolytes (urine, sweat, respiration, stool)

replacement therapy - CORRECT ANSWERS- corrects any existing water and or electrolyte
deficits

isotonic fluids - CORRECT ANSWERS- tonicity equal to plasma in the body
- no fluid shifts because the solutions are equally concentrated
