2. when blood is mixed too vigorously after sample collection
3. when excess alcohol is used to clean the skin and not allowed to dry before blood collection

Question 2

What are 2 causes of hyperproteinemia?

Answer 2

animal is dehydrated and has a elevated total protein concentration

Question 3

What are 2 causes of hypoproteinemia?

Answer 3

animal is overhydrated and has a decreaed total protein concentration

Question 4

What condition is associated with hypernatremia?

Answer 4

an elevated blood level of sodim

Question 5

What condition is assoicated with hyponatremia?

Answer 5

a decreased blood level of sodium

Question 6

Why should you not use the sodium salt of heparin as a coagulant when testing for sodium in the blood?

Answer 6

it can falsely elevate the results

Question 7

What condition is associated with hyperkalemia?

Answer 7

an elevated blood level of potassium

Question 8

What condition is associated with hypokalemia?

Answer 8

a decreased blood level of potassium

Question 9

Why is dehydration usually accompanied by azotemia?

Answer 9

because of urea being an insoluble molecule and how it must be excreted in a high volume of water - which causes dehydration which results in the increased retention of urea in the blood (azotemia)

Question 10

What tests commonly are performed to evaluate the acinar functions of the pancreas?

Answer 10

amylase and lipase, and trypsinlike immunoreactivity and serum pancreatic lipase immunoreactivity

Question 11

What is the acinar function?

Answer 11

it secretes enzyme-rich juice that contains the enzymes necessary for digestion in the small intestine

Question 12

The pancreas is actually two organs, what are they?

Answer 12

one exocrine and one endocrine held together in one stroma

Question 13

What is another name for endocrine portion of the pancreas?

Answer 13

acinar pancreas - comprises the greatest portion of the pancreas

Question 14

What does the acinar pancreas secrete?

Answer 14

enzyme-rich juice that contains the enzymes necessary for digestion in the small intestine

Question 15

What are the 3 primary pancreatic enzymes?

Answer 15

trypsin, amylase, and lipase

Question 16

Define azotemia?

Answer 16

dehydration which results in the increased retention of urea in the blood

Question 17

Define cholestasis?

Answer 17

causes an increase in serum cholesterol in some species

Question 18

Question 19

What assay is sometimes used as a screening test for hypothyroidism?

Answer 19

a cholesterol assay

Question 20

What is the general principle of photmetry?

Answer 20

designed to measure the amount of light transmitted through a solution. The solution must follow Beer-Lambert’s law which states that a direct linear relationship exists between the concentration of an analyte and light absorption when monochromatic light is passed through the sample
