3. What factors can negatively impact the accuracy of cytology findings?

Inadequate staining (insufficient time, smear too thick)

Time for the stained sample to air dry

Diff-quick staining

Impression smears of fresh cut samples

All of the above

4. Which of the following is true about cytology samples?

The smear type is not dictated by the type of sample (e.g., fluid, solid tissue aspirate, biopsy).

History details are not required.

They should be keep out of contact with formalin.

Unstained slides are coverslipped.

All of the above.

5. Use low power (10x) of the microscope to:

Identify good areas to look at (i.e., cells are well spread and well stained).

Initially identify anything that appears strange.

Take a closer look at unusual areas on the slide.

Visualize cells with oil immersion.

A and B.

7. When making slides of solid tissue:

Use fresh cut surface to avoid ulcerations.

Blot first for impression smears.

Scalpel blade scrapings are hard to stain adequately.

All of the above.

A and B.

8. The type of slide made from fluid:

Is dictated by the clarity of the sample.

Is dictated by the color of the sample.

Is dictated by the amount of the sample.

Is dictated by the weight of the sample.

All of the above.

9. Use high power (40x) of the microscope to:

Further evaluate areas that appear strange.

Visualize cells with oil immersion.

Identify blood, inflammation and tissue cells.

All of the above.

None of the above.

10. Old samples that are used for cytology can produce:

Erythrocytosis.

Bacteriopsonin.

Cell lysis.

Anti-mortem: clostridial overgrowth, exfoliation of mesothelial cells, autolysis.

All of the above.

11. Which of the following is not true regarding a "squash smear"?

You should press the bottom and top slide together.

Slides must be at a 90 degree angle.

You should put your drop of blood or aspirate close to the frosted edge.

A and B.

A, B and C.
