fluid 2; water hormones Flashcards
diabetes insipidus
unable to concentrate urine with ADH
SIADH =
syndrome of inapproperiate ADH
hyponatremia
less than 135 mEq/l
inc in water dec in Na in serum
muscle cramps/weakness
increase in salt in serum, leads to cell dehydration
hypernatremia
compulsive drinking of water
psychogenic polydipsia
enters through GI, eliminated through kidneys
sodium
potassium
true polydipsia
fluids are low, water is needed
syndrome of inappropriate ADH
failure of negative feedback with ADH
hypodipsia
loss of reception of thirst
psychogenic polydipsia
compulsive drinking of water
supports potassium secretion
aldosterone
meaning thirst
dipsia
hyperkalemia
potentially fatal cardiac dysrhythmias paresthesias hypotension hyporeflexia leg cramps
supports sodium and water retention (not ADH)
aldosterone
abnormal great thirst
polydipsia
polydipsia
abnormal great thirst
deficiency in cortisol (then aldosterone); more potassium and less water
addison’s disease
extracellular serum range
3.5 to 5 mEq/l
false polydipsia
collecting water instead of cycling through
types of polydipsia
true
false
pyschogenic
alcohol lowers
ADH
hyporeflexia
absence of reflexes
second most abundant cation
potassium
vasopressin
= ADH
the following causes increase in ADH
pain/trauma
nausea
narcotics/nicotine
kalemia
potassium
unable to concentrate urine with ADH
diabetes insipidus
more than 145 mEq/l
hypernatremia
potentially fatal cardiac dysrhythmias
hyperkalemia
hypernatremia
more than 145 mEq/l
increase in salt in serum
leads to cell dehydration
potassium traits
2nd most abundant cation
primary intracellular cation
98% found inside cells
3.5 to 5 mEq/l
bradycardia
abnormally slow hr
absence of reflexes
hyporeflexia
collecting water instead of it cycling through
false polydipsia
abnormally slow hr
bradycardia
dipsia
thirst
potassium is known for helping
heart contraction
aldosterone traits
supports potassium secretion
support sodium and water retention
increases with increased cortisol
fluids are low; water is needed
true polydipsia
98% of potassium is found
inside cells
failure of negative feedback with ADH
syndrome of inappropriate ADH
primary intracellular cation
potassium
thirst is triggered by
hypothalamus
less than 135 mEg/l
hyponatremia
increase in water, decrease in salt in serum
hyponatremia
nonfatal cardiac dysrhythmias
hypokalemia
loss of reception of thirst
hypodipsia
natremia
salt
hypokalemia
nonfatal cardiac dysrhythmias
paresthesias
bradycardia
abnormal great thirst
polydipsia
narcotics
drugs
addison’s disease
deficiency in cortisol (then aldosterone); more potassium and less water
hypodipsia is common for
elderly
