17.What is the difference between diffusion and osmosis?: diffusion moves stuff high to low
("I'll lead"); osmosis moves water low to high ("You'll lead")
18.What is tonicity?: tension or effect that solutes exert on cell size because of water moving
across the cell membrane ("Whoever is the strongest will lead")
19.What is passive transport?: movement of solutes from an area of higher concentration to
an area of lower concentration
20.What is the purpose in passive transport?: to equalize the concentration in both areas
21.What are the three different types of tonic solutions?: isotonic, hypertonic, hypotonic
, PATHO Exam 4 Study Guide | MUST READ
22.What is an isotonic solution?: solute concentration is equal
23.What type of tonic solution would be present with a normal saline: 0.9% NaCl?: isotonic
24.What is an hypotonic solution?: solution concentration is lower than blood
25.What type of tonic solution would be present with half normal saline: 0.45%: hypotonic
26.What is an hypertonic solution?: solute concentration is greater than another solution
27.What type of tonic solution would be present with a 0.9% NaCl + 5% dextrose in
normal saline?: hypertonic
28.Is capillary filtration pressure push or pull pressure?: push pressure
29.Is interstitial hydrostatic pressure push or pull pressure?: push pressure
30.Is capillary colloidal osmotic pressure push or pull pressure?: pull pressure
, PATHO Exam 4 Study Guide | MUST READ
31.What type of capillary interstitial fluid exchange results from blood push- ing against the
walls of the capillary?: capillary filtration pressure
32.What type of capillary interstitial fluid exchange is when the pressure inside a capillary is
greater than the pressure in the surrounding interstitial space, fluids and solutes inside the
capillary are forced into the interstitial space and vice versa?: interstitial hydrostatic pressure
33.What type of capillary interstitial fluid exchange occurs when there is reab- sorption which
prevents too much fluid from leaving the capillaries; requires H20 and concentration gradient?:
capillary colloidal osmotic pressure
34.What is third space accumulation?: when push pressure is greater than pull pressure

38.What are causes of hypovolemic?: diarrhea, vomiting, diuretic use, sweating
39.What type of hyponatremia is the retention of water/dilution of Na- Normal ECF volume?:
euvolemic
40.What are the causes of euvolemic?: SIADH or thirst disorder
41. What type of hyponatremia is an increase in extracellular fluid volume?: -
hypervolemic
42.What are some causes of hypervolemic?: edema forming- CHF, cirrhosis, kidney disease
43.What is hypernatremia?: >145 mEq/L
44.What are some causes of hypernatremia?: excessive water losses, de- creased water
intake, excessive sodium intake
