Renal Body Fluid Compartments -Rogers

Question 1

total fluids ingested in a day

Answer 1

2100 total intake = 2300

Question 2

volume contraction

Answer 2

ECF volume is decreased = decreased blood volume, lowered BP

Question 3

volume expansion

Answer 3

ECF volume increases

Question 4

Hyperosmotic

Answer 4

osmolarity in the ECF increased

Question 5

amount of water in the body

Answer 5

50% - 70%

Question 6

amount in ICF and ECF

Answer 6

ICF : 2/3 ECF : 1/3

Question 7

ECF is what

Answer 7

interstital fluid (around cells) plasma (in blood vessels) * divided by capillary wall

Question 8

ICF is what

Answer 8

intracellular fluid only inside cells

Question 9

water is added where and leaves from the body from where

Answer 9

leaves and enters the body from the ECF

Question 10

controlling the plasma does what to the interstitual fluid

Answer 10

controls the intestitiual fluid the same way

Question 11

non-electrolyte electrolyte

Answer 11

nonelectrolyte : cant dissolve in water (lipids, glucose, urea) and have no charge electrolytes : dissolve in water and have charge ****can change fluid volumes more****

Question 12

ICF composition

Answer 12

K+, PO4-3, anion proteins

Question 13

ECF composition

Answer 13

NA+, Cl-, HCO-3, some anion proteins (ONLY in plasma) no proteins in interstitual fluid

Question 14

hypotonic cell environment does what

Answer 14

swells the cell

Question 15

Na+ concentration in ECF

Answer 15

140mEq

Question 16

N + concentration ICF

Answer 16

5mEg

Question 17

3 main solutes in the ECF

Answer 17

sodium Glucose Urea (BUN)

Question 18

Serum osmolality calculation

Answer 18

Osmolality = (NA+ x 2) + (glucose)/18 + (BUN)/2.8

Question 19

Serum osmolality calculation eyeball it

Answer 19

plasma osmolality = 2 (plasma NA+)

Question 20

when is ADH secreted from PP

Answer 20

andiotensin 2 low preload high plasma osmolality sympathetic activation =Increase BP (H2O and some NA reabsorption)

Question 21

ANP has what 3 functions

Answer 21

1. Arterial dilation (decrease TPR) 2. increase fluid loss (decrease preload_ 3. inhibit renin, aldosterone, ADH (decreases TPR and preload)

Question 22

sweating and lots of fluid loss does what

Answer 22

water moves out from ICF to the ECF and cells shrink

Question 23

sweating a lot and drinking equally as much water as lost

Answer 23

increase water in ECF and no NA+ increased (hyposmolarity) = cells swell

Question 24

2 types of dehydration

Answer 24

1. Hypernatremic dehydration 2. Hyponatremic dehydration

Question 25

Hyponatremic dehydration

Answer 25

more NA+ loss then water loss water moves TO ICF ECF is hypoosmolality - tachycardia, hypotention

Question 26

Hypernatremia dehydration

Answer 26

more H2O loss then NA water moves TO ECF ECF is hyperosmolality * can cause edema

Question 27

Hypernatremia dehydration and Hyponatremic dehydration can cause what symptoms

Answer 27

confusion brain cells shrink or swell weakness, muscle cramps hyperreflex

Question 28

Darrow-Yannet Diagrams during volume contraction casues and what happens

Answer 28

hyperosmotic enviornment Diabetes, dehydration, alcoholism, De ECF, De ICF, In osmolality

Question 29

Darrow-Yannet Diagrams during diabetes casues and what happens

Answer 29

excessive thirst and urination 1. body cant make ADH, or kidneys cant respond to ADH= volume contraction = water keeps getting excreted 2. increased glucose pulls water into CD

Question 30

Water diuresis

Answer 30

increased H2O excretion (no NA) caused from diabetes*, increased water intake

Question 31

solute diuresis

Answer 31

increased H2O and NA+ excretion caused by high NACL in diet hyperglycemia* high protein intake AKI recovery

Question 32

Darrow-Yannet Diagrams during adrenal insufficiancy casues and what happens

Answer 32

no aldosterone can be made In ICF, De ECF, De osmolality

Question 33

Darrow-Yannet Diagrams during SIADH (inappropriate ADH) + excess water intake casues and what happens

Answer 33

ECF is hypotonic In ECF, In ICF, De osmolality

Question 34

Darrow-Yannet Diagrams during hemorrage, diarrhea, vomiting casues and what happens

Answer 34

only ECF loss SAME ICF and SAME osmolality

Question 35

Darrow-Yannet Diagrams during injecting isotonic NACL saline casues and what happens

Answer 35

ECF INCREASES ICF + osmolality = same

Question 36

Darrow-Yannet Diagrams during very high NACL intake and saline injection casues and what happens

Answer 36

ECF increases INF decreases, osmolality decreases (water goes from ICF to ECF) from ingesting NA+

Question 37

when does hematocrit increase

Answer 37

when ECF decreases (when ECF increases, Hematocrit decreases since you have added to it)

Question 38

Look at these 2 tables

Answer 38

Look at these 2 tables****
