Question 1

Anion Gap

Answer 1

Na-(Cl+ HCO3)

Question 2

Fluid movement formula across a membrane

Answer 2

Flow= k [(Pc+πif) - (Pif+πc)]

Flow= konstant * ( capillary pressure plus interstitial oncotic pressure- Interstital pressure plus oncotic pressure)

Question 3

Isosmotic

Answer 3

same concentration of solutes ~300mOsm

Question 4

Isotonic

Answer 4

Any solution that does not change cell volume.

Question 5

Isooncotic

Answer 5

Same concentration of protein as plasma~ 1mM albumin

Question 6

normal water distribution

Answer 6

Distributes proportionately across all fluid resivoirs because they are all permeable to water

Question 7

saline distribution

Answer 7

distributes proportionately to only plasma and interstitial fluid because the Na K pump prevents ion entry into the cell preventing water entry

Question 8

1/2 normal saline

Answer 8

Half distributes as water, the other half as saline.

Question 9

Isooncotic saline

Answer 9

Contains recombinant albumin and fluid stays in the plasma because the protein cannot leave, therefore, water cannot leave

Question 10

5% dextrose distribution

Answer 10

Is basically pure water except it doesn’t lyse the cells from the glucose in it. The glucose is absorbed up and taken care of by the cells to not have any osmotic effect.

Question 11

Hypovolemia distribution

Answer 11

IV fluid stays within the plasma because the pressure is decreased and this leads to less filtration out.
