complete solutions
0.5mL/kg/hr - correct answer ✔✔ minimum urine output for adult
- water retainer
- vasoconstrictor (also called Vasopressin)
- produced by hypothalamus
- store and released from posterior pituitary - correct answer ✔✔ ADH (antidiuretic hormone)
- 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 - correct answer ✔✔
ADH pathway
- 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 - correct answer ✔✔ ANP (atrial natriuretic peptide)
,- forces fluids and solutes through the capillary wall and into the tissue spaces - correct answer
✔✔ hydrostatic pressure
- pulling force of albumin in the intravascular spaces
- pull fluid into vasculature - correct answer ✔✔ colloid osmotic pressure
- replaces normal ongoing losses of water and electrolytes (urine, sweat, respiration, stool) -
correct answer ✔✔ maintenance fluid therapy
- corrects any existing water and or electrolyte deficits - correct answer ✔✔ replacement
therapy
- tonicity equal to plasma in the body
- no fluid shifts because the solutions are equally concentrated
- LR
- NS
- D5W - correct answer ✔✔ isotonic fluids
- lower concentration of solutes in the vasculature than in the cell
- fluid shifts into the cell to dilute the electrolytes (CELL SWELLS)
- 0.45NS - correct answer ✔✔ hypotonic fluids
- higher concentration of solutes in the vasculature than in the cell
, - pulls fluid out of cells and into the vessels (CELL SHRINKS)
- D5 .45NS
- D5NS
- D5LR
- 3%, 7%, 23.4% NaCl - correct answer ✔✔ hypertonic fluid
- pull fluid into bloodstream
Albumin
- 5% is osmotically equal to plasma
- 25% draws 4 times the normal volume into the circulation - correct answer ✔✔ colloids
- not a risk free fluid replacement
- this is liquid transplant - correct answer ✔✔ blood
- fluid is not lost from the body but the fluid is not available for use in the intracellular or
extracellular compartments (fluid is in between tissues/cells)
- this patient is intravascularly dry and still needs more fluid
- - correct answer ✔✔ third spacing
- no it will aggreggate the platelets - correct answer ✔✔ can you give platelets through the
ranger
- less than 135 -145
