1

The normal size of a canine red blood cells is microns. (number)

1

When reading hematocrit results, you should line the meniscus of the RBC stack up with...

1

Normal values (type of test) for dogs are 37-55%, and cats are 24-45%.

By adding 1 gt of saline to Rouleaux will make it disperse; Agglutination will stick together.

When evaluating RBC indicies you must know terminology. A normal MCHC is called ❌ while a normal MCV is ❌. Decreased MCV would be considered ❌ and an increase would be ❌. If the MCHC was low it would be considered ❌, and the high result would be ❌.

PCV/3 = (full word)

1

A _____ count is performed when anemia is suspected

1

Only counting the aggregate reticulocytes during a reticulocyte count is standard procedure in dogs and cats.

1

Why would TP using serum yield lower test results?

1

A refractometer is used to conduct a TP test.

1

Dehydration will cause TP results to be

( Neutrophils, Basophils, Eosinophils, Monocytes ) are the most abundant WBC in most mammals and are known as ( Heterophils, Barr Bodies, Exoticophils, Hypersegmented Neutrophlis ) in avian, reptiles, fish, rats, rabbits, and guinea pigs. With the exception of bovine, who show ( Lymphocytes, Mycoplasma, Monocytes, Basophils ) as their most abundant WBC.

2

Normal TP ranges for serum are ❌ and plasma is ❌.

5.5 - 7.5 g/dL

6 - 8 g/dL

3

❌ = Average number of WBC x 2000
❌ = (100/100 + nRBCs) x WBC count
❌ = Percentage of type x WBC count

What is the main job of a Monocyte

4

Platelet Count can be found by first scanning ( 10, 5, 50, 100 ) fields to find the average number/hpf. The normal range is between ( 8-10, 0-3, 1-5, 10-12 ) platelets/hpf. After the average is determined you multiply by ( 20,000, 20, 200, 2,000 ). If your results are less than 100,000 /uL your patient may have ( thrombocytopenia, hypopenia, platelet mass deficiency, vWD ).

1

Platelets, vWf, and vessel walls are essential in hemostasis, which produces platelet adhesion, activation, and aggregation.

1

During hemostasis fibrinogen converts to fibrin and strengthens the clot.

1

During tertiary hemostasis aids to break down the clot.

2

There are two types of analyzer types, Flow cytometry, which uses ❌ technology, such as the IDEXX Lasercyte in lab class; and Impedance, which uses a ❌ to process results, such as the Heska.
