CMP Flashcards
what is another name for a chem 7
BMP (basic metabolic panel)
what is another name for a chem 12
CMP (comprehensive metabolic panel)
What does a CMP have that BMP leaves out
ALT, AST
Creates osmotic pressure in the intravascular space
protein
what is a marker of malnorishment
pre albumin
what percentage of total protein should albumen be
60%
where is albumen synthesized
liver
Increased albumen could indicate
dehydration
what percentage of your body weight is TBW
.6 men .55 women
what is the distribution of ICF / ECF
2/3 ICF
1/3 ECF
If albumin is increased what could that represent
dehydration
what is the only ion that is high inside the cell
K
the solute or particle concentration of a fluid
Osmolality
normal osmolarity
280-295
what is the equation for osmolarity gap
measured - calculated
if osmolarty gap is > 10
consider exogenous substance
Normal Na
135-145
Normal K
3.5-5.0
Normal K
98-106
normal Co2
22-32
Abnormal Extracellular Fluid Volume (ECFV)
is due to sodium control mechanisms
Abnormal Extracellular Fluid (ECF) sodium concentration
is due to problems with water control
what can cause Pseudohyponatremia
multiple myeloma
Congestive heart failure
Renal failure
Nephrotic syndrome
Hepatic cirrhosis
All symptoms of what
BUN stands for what
Blood urine nitrogen
how do we transport enzymes
proteins
when the person is low on sodium what do you want to check
Osmolality Gap
what is the most commonly abnormal ion
sodium
whenever protein is high what will also be high
water
DKA stands for what
Diabetic keto acidosis
the labs measure what type of fluid
plasma
Hyponatremia with Hypervolemia means what
too low sodium
&
too high salt
Hyponatremia with Hypovolemia what kind of medications
Diuretics OR diarrhea
, vomiting
(symptoms of what)
Hypothyroidism (check thyroid function)
SIADH (syndrome of inappropriate ADH secretion)
The most common cause of euvolemic hyponatremia
Due to impaired renal free water excretion
Can see in lung cancer pts
Diuretic use (without volume depletion)
Adrenal Insufficiency
Primary (diabetes insipidus) or psychogenic polydipsia
Tea and toast diet
Hyponatremia with Euvolemia
hyperkalemia may cause what on EKG
peaked T waved
what is the cause of U wave
hypokalemia
How is potassim eliminated
kidneys
rhabdomyolysis causes what ion to be off
Potassium
Potassium >5.0 is
potentially dangerous
what heart arrhythmia is associated with hypokalemia
A Fib
what is more common acidosis or alkalosis
acidosis
relationship between PH and K
Inverse
high K in labs what could this mean
metabolic acidosis if PH is low (meaning K may be low)
what is used to measure parathyroid function
Calcium
