Accepted Answer

Packed cell volume (PCV) or hematocrit

Answer

Mean corpuscular volume (MCV)

Answer

Mean corpuscular hemoglobin concentration (MCHC)

Answer

Red cell distribution width (RDW)

Question 3

What is the approximate normal packed cell volume (PCV) range for a healthy adult dog?

Accepted Answer

37–55%

Answer

20–30%

Answer

60–70%

Answer

10–20%

Question 4

An elevated alanine aminotransferase (ALT) level in a dog most specifically suggests:

Accepted Answer

Hepatocellular damage or liver cell injury

Answer

Reduced glomerular filtration and kidney disease

Answer

Pancreatic inflammation (pancreatitis)

Answer

Skeletal or cardiac muscle breakdown

Question 5

What does the finding of thrombocytopenia on a CBC indicate?

Accepted Answer

A platelet count below the normal reference range, which may impair clotting and increase bleeding risk

Answer

An elevated platelet count above the normal reference range

Answer

Abnormal platelet shape with reduced function but normal numbers

Answer

The complete absence of all blood cell lines including platelets

Question 6

Which two blood chemistry values are MOST commonly used to assess renal function in veterinary patients?

Accepted Answer

Blood urea nitrogen (BUN) and creatinine

Answer

Alanine aminotransferase (ALT) and alkaline phosphatase (ALP)

Answer

Total bilirubin and bile acids

Answer

Amylase and lipase

Question 7

A CBC differential showing increased band neutrophils (immature neutrophils) alongside mature neutrophilia is called a 'left shift' and most likely indicates:

Accepted Answer

Active bacterial infection or significant systemic inflammation causing increased demand for neutrophils

Answer

A chronic allergic response with associated eosinophilia

Answer

Viral infection causing lymphocytosis and neutropenia

Answer

Bone marrow suppression from chemotherapy or toxin exposure
