A family of peptides called natriuretic peptides serves to regulate
sodium and water metabolism
Renin is produced in the
kidneys
Aldosterone stimulates
Na reabsorption by the kidneys
,How much of our body water is found in extracellular fluid, including plasma
1/3
Which of the following conditions will cause an increase anion gap
Renal failure
In the blood, bicarbonate leaves the red blood cell and enters the plasma
through an exchange mechanism with which of the following ions
Chloride
Which gland secretes aldosterone
adrenal gland
The cation with the highest extracellular concentration is
Sodium
A patient with a toxic blood alcohol would cause which of the following
An increased osmolal gap
The formulae for calculating serum osmolality that incorporates a correction
for the water content of plasma is
2 Na + Glucose/20 + BUN/3
,Osmolal gap is
The difference between the calculated and measured osmolality values
The purpose of the sodium-potassium ATP pump is
To pump sodium out of the cell and potassium into the cell
Which is true concerning total serum carbon dioxide measurements
They are largely equivalent to bicarbonate levels
What is meant by the term pseudohyperkalemia?
Falsely increased due to hemolysis
Which of the following electrolyte levels best correlate with plasma osmolality?
Sodium
Electrolyte exclusion effect is characterized as which of the following
A falsely low serum sodium result in a grossly lipemic specimen
Elevated sweat chloride is associated with which disease
cystic fibrosis
, Interstitial fluid is the fluid
Around the cells
The intracellular fluid compartment is made of all the water
Within the cells
Which hormone stimulated water reabsorption
ADH/vasopressin
Which of the following conditions may be characterized by an increased anion
gap
All of the above
Which of the following sequences accurately reflects the renin-angiotensin-
aldosterone system in response to hyponatremia
Renin is released from the kidney; renin converts angiotensinogen to angiotensin
I; angiotensin I is converted to angiotensin II.
Angiotensin II is a potent vasoconstrictor that
Stimulates ADH secretion and thirst.
Calculate the anion gap given the following data: sodium = 143 chloride = 105 and
HCO3
= 25
