25
Water moves out of the cell when the extracellular fluid is hypo or hypertonic?
hypertonic
26
when the ECF is hypotonic H2O moves (into or out of) the cell through ( ) to balance osmolality
into | osmosis
27
When the ECF is hypertonic, H2O moves (into or out of) the cell through ( ) to balance osmolality
out of | osmosis
28
What are cerebral manifestations that occur when neurons swell because of hypernatremia
confusion, LOC, seizures, lethargy, coma
29
Why are clinical manifestations of hyperNa+ and hypo Na+ so similar?
Neurons in both care are not functioning properly and manifest nonspecific cerebral disfunction
30
Angiotensin II and increased K+ stimulate secretion of what? To what end?
Aldosterone increases renal Na+ and H2O absorbtion - increase BP; increased renal excretion of K+ and H+ ions
31
Low plasma Ca++ stimulates secretion of what hormone? To what end
Parathyroid hormone | increase reabsorption of bone, renal reabsorption of Ca++ and inhibits renal reabsorption of phosphate
32
Increased volume in cardiac atria stimulates secretion of what? to what end
Atrial Natriuretic peptide | increases renal Na+ and H2O excretion - lowers BP
33
High plasma Ca++ increases secretion of what? To what end?
Calcitonin | Inhibits osteoclasts in bones
34
fluid that is part of the extracellular fluid
blood and interstitial fluid
35
all the fluid outside of cells --fluid in vessels and between cells
extracellular fluid
36
acid secreted by the lungs
volatile acid - carbonic acide
37
acid secreted by kidneys
nonvolatile acid - metabolic acid - sodium bicarb
38
pH of blood is <7.35
acidemia
39
too much acid, too little base (ratio is off)
acidosis
40
in acid-base imbalance returns imbalance between acid and base to normal levels
correction
41
returns ratio of bicarb to carbonic acid to 20:1 which is normal, but acid/base balance is still off
compensation
42
1/3 of body H2O is ( ) fluid, 2/3s is ( ) fluid
extracellular | intracellular
43
a standard 68 K man has ( ) liters of total body H2O
40.8
44
Excessive fluid within the interstitial space is called
edema
45
an ( ) fluid has the same concentration of solute as plasma
isontonic
46
a person with lung disease could develop a primary ( ) acid-base imbalance, but a person with kidney diseases may develop a primary ( ) acid-base imbalance
respiratory | metabolic
47
when the blood pH is 7.40, the bicarbonate to carbonic acid ratio is
20:1
48
the buffer pair is
a weak acid and its conjugate base
49
anion gap may help distinguish between different causes of
metabolic acidosis
50
overuse of phosphate-containing OTC enemas can cause ( ) which will ( ) the plasma Ca++ concentration
increased phosphatemia | decrease
51
isotonic fluid excesses and hypoK+ can cause
edema, weight gain, constipation, muscle weakness abdominal distention
52
slow, shallow respers, blood pH <7.35, blood PaCO2 increased is caused by
respiratory acidosis
53
hyperventilation causing paresthesias of fingers, lightheadedness, confusion
respiratory alkalosis
54
repeated vomiting, tachycardia, rapid wt loss, decreased urine output, muscle weakness, slow shallow breathing & lethargy
isotonic fluid deficit, hypoK+, metabolic alkalosis
55
hyperparathyroidism - fatigue, anorexia, constipation, lethargy
hypercalcemia
56
which direction does insulin move K+?
from ECF into cell
57
which direction does epi move K+?
from ECF into cell
58
which direction does alkalosis move K+?
from ECF into cell
59
which direction does hyper Na+ move H2O
from cell to ECF
60
gravity pulls fluid to lowest place
dependent edema
