NUR168 EXAM 4 QUESTIONS AND VERIFIED
ANSWERS
What responsibilities does water have in the body in terms of transportation?
Transporting nutrients to cells and wastes from cells. Transportation of hormones,
enzymes, blood platelets, and red and white blood cells.
How does water support cellular functions?
Improving cellular metabolism and chemical activity; Serving as a solvent for
electrolytes and non-electrolytes
What physiological purposes does water serve in the human body?
Helping to maintain normal body temperature; Facilitating digestion and
facilitating excretion. acts as a tissue lubricant.
How much water does the brain contain?
90%
How much water are the muscles made of?
73%
How much water do the bones contain?
22%
,How much water does the blood contain?
83%
Intracellular Fluid (ICF)
Fluid within cells: 70%
Extracellular Fluid (ECF)
Fluid outside cells: 30%
Contains intravascular and interstitial fluids.
What is the fluid shift following a burn?
The massive fluid transfers from the intravascular to the extravascular space
causing edema and hemoconcentration.
Along with the drop in intravascular volume, there is a fast decrease in cardiac
output, which progressively returns to normal within 24 to 48 hours of burn injury.
Solvents
Water is a liquid that holds a material in solution.
Solutes
substances dissolved in a solution (including electrolytes and non-electrolytes).
Where does your body lose fluids?
, Kidneys: Urine
Feces in the intestinal tract.
Skin: sweating.
Insensible water loss (not easily quantified).
Hypovolemia
deficit in the amount of water and electrolytes in ECF with near-normal
water/electrolyte ratio
Third-space fluid shift.
The dispersion of bodily fluids into potential body niches.
Fluid intake; ingested water
1300mL
Fluid intake; ingested food
1000mL
Fluid intake; metabolic oxidation.
300mL
Fluid outflow; Kidneys
1500mL
