Blood Chemistries QUIZ/Lab Flashcards
T/F: Chemistry analysis can only be performed on blood serum (not urine or other body fluids).
False
T/F: Creatinine is a very sensitive test for kidney function and will rise when 25% of the nephrons have been injured.
False
T/F: A decrease in blood pH is termed acidosis.
True
T/F: Blood urea nitrogen (BUN) will rise in dehydrated patients or in the event of decreased kidney function.
True

How would you describe this canine serum sample?
1. hemolyzed
2. conjugated
3. normal
4. lipemic
- lipemic
A low albumin may signal:
1. poor pancreas function
2. poor thyroid function
3. poor splenic function
4. poor liver function
poor liver function
T/F: It is not possible to determine the oxygen content of arterial blood in a chemistry analyzer.
False
T/F: Hemolysis in the serum/plasma sample may cause incorrect results to be reported by the chemistry analyzer.
True
Elevated amylase may signal inflammation of the:
1. adrenals
2. parathyroid
3. kidney
4. pancreas
- pancreas
An elevated Alkaline Phosphatase (AlkP) may occur with liver disease or:
1. kidney disease
2. thyroid disease
3. pancreas disease
4. certain medications
certain medications
TLI (Trypsin-like immunoreactivity) is utilized to evaluate:
1. parathyroid
2. liver
3. exocrine pancreas
4. endocrine pancreas
exocrine pancreas
Name two general reasons why the veterinary team evaluates blood and urine.
a. Diagnose cause of health problem
b.
c.
b. generate baseline for the specific patient
c. monitor response to care/progression of problem
A cat patient is 10% dehydrated and its urine specific gravity is 1.010. What is your interpretation of this finding?
Your answer:
- The kidneys cannot properly function as the urine is very dilute (normal 1.030 USG) for dehydration. The kidneys are having difficulty maintaining the hydration/electrolytes of the cat. Further testing (blood work to see BUN, etc) should be done to further evaluate kidney function.
Instructor:
- The urine is isosthenuric (the same concentration as plasma), therefore the patient is not forming a concentrated urine when it is 10% dehydrated.
This is an inappropriate response by the kidneys. This patient is in kidney failure. (12-14% dehydrated leads to death)
