Laboratory Tests 1. Which of the following tests is best suited to evaluate kidney function in dogs? A. Serum biochemistry B. Complete blood count C. Urinalysis D. Serum electrolytes Answer: A. Serum biochemistry. Rationale: Serum biochemistry includes parameters like BUN and creatinine that specifically assess kidney function. 2. What does a high concentration of bilirubin in the urine typically indicate? A. Liver disease B. Diabetes mellitus C. Urinary tract infection D. Renal failure Answer: A. Liver disease. Rationale: Bilirubinuria often indicates increased bilirubin production due to liver dysfunction. 3. Which of the following is NOT a common indication for a complete blood count (CBC)? A. Anemia B. Infection C. Electrolyte imbalance D. Leukemia Answer: C. Electrolyte imbalance. Rationale: Electrolyte imbalances are typically assessed through serum biochemistry, not CBC. 4. When evaluating a blood smear, which of the following findings might indicate anemia? A. Increased platelet count B. Decreased hematocrit C. Enlarged leukocytes D. Decreased protein levels Answer: B. Decreased hematocrit. Rationale: A low hematocrit indicates that there are fewer red blood cells than normal. 5. In assessing liver function, which biochemical test is considered the best indicator of hepatic synthetic function? A. Alanine transferase (ALT) B. Alkaline phosphatase (ALP) C. Serum albumin D. Total bilirubin Answer: C. Serum albumin. Rationale: Serum albumin reflects the liver's ability to synthesize proteins. 6. Which of the following is a characteristic of feline leukemia virus (FeLV) testing? A. Requires a serum sample B. Can detect changes in blood cell counts C. Always produces a negative result if the cat is healthy D. Can be done with a rapid test kit Answer: D. Can be done with a rapid test kit. Rationale: FeLV testing can be performed using rapid antigen tests. 7. What role do reticulocytes play in the diagnosis of anemia? A. They indicate white blood cell levels. B. They are immature red blood cells released during regeneration. C. They are always present in healthy animals. D. They are indicative of kidney function. Answer: B. They are immature red blood cells released during regeneration. Rationale: The presence of reticulocytes suggests the bone marrow's response to anemia. 8. Select all that apply: Which of the following tests can indicate the presence of pancreatic disease in dogs? A. Serum lipase B. Serum amylase C. Total protein D. Fructosamine Answer: A. Serum lipase, B. Serum amylase. Rationale: Both lipase and amylase are enzymes that may be elevated in pancreatic disorders. 9. Which of the following conditions is a contraindication for blood transfusion in dogs? A. Severe thrombocytopenia B. Pulmonary edema C. Autoimmune hemolytic anemia D. Hypoproteinemia Answer: B. Pulmonary edema. Rationale: Transfusions can worsen pulmonary edema due to volume overload. 10. How is a urinalysis commonly used in veterinary practice? A. To diagnose infectious diseases only B. To assess hydration status and urinary tract health C. To measure serum electrolytes D. To evaluate bone marrow function Answer: B. To assess hydration status and urinary tract health. Rationale: Urinalysis provides valuable information about kidney function and urinary tract conditions. 11. Which of the following is an important consideration when collecting a urine sample for analysis? A. Sample must be collected in a glass container B. The sample should be cooled immediately C. The sample should be a midstream catch D. The sample must be collected after a meal Answer: C. The sample should be a midstream catch. Rationale: Collecting a midstream sample minimizes contamination. 12. In dogs with hyperadrenocorticism (Cushing's disease), which laboratory finding is most commonly observed? A. Hyperglycemia B. Thrombocytopenia C. Hyperkalemia D. Hyponatremia Answer: A. Hyperglycemia. Rationale: Cushing's disease often leads to increased blood glucose levels. 13. What type of sample is primarily used for antigen testing of infectious diseases such as parvovirus? A. Blood B. Feces C. Urine D. Skin Answer: B. Feces. Rationale: Fecal samples are used to detect parvovirus antigen in infected dogs. 14. Which laboratory test is essential for diagnosing diabetes mellitus in cats? A. Blood glucose B. BUN C. Creatinine D. Fructosamine Answer: A. Blood glucose. Rationale: Persistent hyperglycemia is a definitive indicator of diabetes mellitus. 15. Which of the following would you expect to find in a dog with acute kidney injury? A. Low urine specific gravity B. Elevated creatinine levels C. Decreased blood urea nitrogen D. Increased calcium levels Answer: B. Elevated creatinine levels. Rationale: Acute kidney injury typically leads to a rise in creatinine due to reduced kidney function. 16. In cats, which laboratory finding typically indicates dehydration? A. Decreased urine specific gravity B. Increased serum creatinine C. Low protein levels D. Normal electrolyte levels Answer: B. Increased serum creatinine. Rationale: Elevated serum creatinine often indicates dehydration affecting kidney function.
