QuestionAnswer
A family of peptides called natriuretic peptides serves to regulate sodium and water metabolism
A patient with a toxic level of blood alcohol would cause what to happen to their osmolality/ they'd have an increased osmolal gap
A patient with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) would present with what kind of laboratory results? Decreased serum sodium, osmolality, chloride, and increased urine sodium
Angiotensin II is a potent vasoconstrictor that stimulates ADH secretion and thirst
bile acids are synthesized in the liver from which lipid? cholesterol
chloride in sweat can be measured by which of the followitn techniques? coulometry and amperometry
cholesterol is a cyclopentanoperhydrophenanthrene nucleus
elevates sweat chloride is associated with which disease cystic fibrosis
freezing point depression is one of the colligative properties of a solution
HDL cholesterol+LDL cholesterol+chylomicrons---->HDL These are used as precipitating reagents for determining cholesterol Heparin-manganese chloride, Dextran -sulfate-MN(II), and Phosphotungstate-Mn(II)
Hyopkalemia can be seen in these conditions starvation, alkalosis, and diarrhea
In the blood, bicarbonate leaves the red blood cell and enters the plasma through an exchange mechanism with which of the following ions? chloride
in uncontrolled diabetes mellitus, cholesterol and triglycerides are increased
measurement of sodium, potassium, and chloride are commonly performed in laboratories using what method Ion selective electrodes
What formula is used to calculate plasma osmolality? 2(Na)+(glucose/18)+(BUN/2.8)
High HDL cholesterol is not a risk factor for what coronary heart disease
1secondart causes of elevated LDL can include chronic renal failure, hypothyroidism, and obstructive liver disease
what is the desirable cutoff for serum LDL cholesterol recommended by the National Cholesterol Education Program 100 mg/dL
Serum lacks what kind of constituent? fibrinogen
The borderline range for cholesterol levels as determined by NCEP is 200-240 mg/dL
The Friedwald formula for estimating LDL cholesterol should not be used when Triglyceride is greater than 400 mg/dL
The National Cholesterol Education Program ATP III goal for desirable HDL cholesterol is greater than or equal to 60 mg/dL
The anion gap is determined from which groups of electrolytes sodium, chloride, potassium, and TCO2
the anion with the highest extracellular concentration is chloride
the cation with the highest extracellular concentration is sodium
the cation with the highest intracellular concentration potassium
the enzymatic determination of glycerol in triglyceride analysis usually involves conversion of glycerol to glycerol phosphate
the first step in the enzymatic cholesterol reaction, which result in cholesterol esterase is hydrolysis of cholesterol esters
The following are criteria for clinical Diagnosis of Metabolic Syndrome Elevated waist circumference, Elevated triglycerides, reduced HDL-C
the lipoprotein fraction that has the highest ratio of lipid to protein is chylomicrons
the presence of only slightly visible hemolysis can significantly increase the serum level of which of the following ions potassium
the serum of a freshly drawn blood sample is slightly turbid, there is is probably because triglycerides only are increased
which apolipoprotein has the ability to increase the risk of coronary heart disease Apo B100

what is one condition that is associated with hypernatremia diabetes insipidus
What conditions can be characterized by an increased anion gap salicylate intoxication, diabetes mellitus, lactate acidosis
what condition can cause an increased anion gap renal failure
what electrolyte levels best correlate with plasma osmolality sodium
what lipid fractions are very large molecules with a low density and give plasma a milky appearance when present in increased amounts? chylomicrons
what sequences reflect the renin-angiotensin-aldosterone system in response to hyponatremia renin is released from the kidney; renin converts to angiotensinogen to angiotensin I; angiotensin I is converted to angiotensin II
Increased total cholesterol, and a decreased HDL cholesterol puts people at the highest risk for coronary heart disease
