NSG 170: Fluid and Electrolytes || Questions and Correct Detailed
Answers.
osmosis correct answers - diffusion of water from area of low solute concentration to area of
high solute concentration
diffusion correct answers - solutes move from area of higher concentration to one of lower
concentration
filtration correct answers - movement of water, solutes occurs from area of high hydrostatic
pressure to area of low hydrostatic pressure
active transport correct answers - maintains higher concentration of extracellular sodium,
intracellular potassium (Sodium-Potassium Pump)
major cations correct answers - sodium
- potassium
- calcium
- magnesium
- hydrogen ions
(all positively charged)
major anions correct answers - chloride
- bicarbonate
- phosphate
- sulfate
- proteinate ions
(all negatively charged)
, isotonic solution correct answers - solution that has the SAME osmotic pressure as blood
- ex. normal saline (NS), lactated ringers (LR), and 5% dextrose in water (D5W)
hypotonic solution correct answers - solution that has a LOWER osmotic pressure than blood
- ex. 1/2 normal saline (1/2NS or 0.45%NaCl)
- WATER MOVES INTO CELLS
hypertonic solution correct answers - solution with a HIGHER osmotic pressure than blood
- have a higher osmotic press
- WATER MOVES OUT OF CELLS
intracellular fluid correct answers - comprises about 2/3 of body's fluid, skeletal muscle mass
- primarily water
extracellular fluid correct answers - comprises only 1/3 of body's fluid
- primarily NaCl and water
- found in plasma and interstitial space, CSF, pericardial, synovial
Which solution is the only solution that may be given with blood administrations? correct
answers Normal Saline
colloid IV fluids correct answers - human albumin, derived from plasma
- 5% albumin - restores protein levels, used with burns, severe trauma, pancreatitis
- 25% albumin - used with fluid restriction to diminish excess edema, treated like blood products
water correct answers - essential for life, major solvent in body, present in and surrounding every
cell
