Clin Path Final Study Guide
1. What types of items go into a biohazard bag?: Biological materials that are not sharp
2. Biohazard bag:
3. What are some examples of what goes into a biohazard bag?: syringes, tongue
depressors, paper towels, and gloves, cotton balls, blood
4. What types of items go into a sharps container?: Contaminated sharps with sharp edge or
surface, glass, needles
5. Sharps container:
6. Name some examples of what goes in a sharps container.: test tubes, microscope slides,
needles, used glass
7. Centrifuge:
,8. Refractometer:
9. Incubator:
,10. Microscope:
11. What is a centrifuge used for in the lab?: separates substances of different densities that are
in a solution
12. Could you tell me how to safely load the centrifuge?: always be sure to balance the
centrifuge with tubes of equal size and weight
13. What could happen if centrifuge is not loaded properly?: Damage to the unit and injury
to the operator can occur
14. What is the supernatant?: liquid portion on top
15. What is the sediment?: solid portion on bottom
16. Why are time and speed settings important?: The time and speed settings can be changed
to accommodate different specimens and different diagnostic test preparations
17. What happens if you spin too fast?: cells rupture and morphological features are destroyed
, 18. What happens if you spin too slow?: incomplete separation or concentration of specimens
19. What is the incubator used for?: culture and sensitivity testing and to help provide ideal living
conditions to support the growth of the organisms into a larger number
20. At what temperature should you set this instrument for incubation of most
samples?: 37°C (98.6°F)
21. How should culture plates be placed inside the incubator?: Culture plates should be
inverted when placed inside the incubator to prevent the formation of condensation on the agar surfaces and do not
place more than 4 plates in a stack to provide optimum incubating temperatures
22. What is a refractometer used for?: Measures the concentration of solids dissolved in a liquid which
do not separate out of solution when centrifuged
