Multiple Choice
Identify the choice that best completes the statement or answers the question.
1. Tube length when referring to the microscope is the:
a. Resolution power of the objective
b. Distance from the eyepiece to the objective
c. Numerical aperture
d. Magnitude of the image on the stage
2. What is the most useful corrective action for the microscope when fine details cannot be visualized
in immature cells?
a. Open up diaphragm for maximum light.
b. Wipe off lenses with lens cleaner.
c. Get a new slide.
d. Move to a lower power.
3. Which of the following behaviors is a violation of standard precautions?
a. Handwashing after glove removal
b. Use of impermeable laboratory gowns
c. Use of goggles and face shields
d. Placing laboratory notebooks on laboratory work area
4. Standards and calibrators differ from control materials because:
a. An exact amount of analyte is present in a standard or calibrator
b. A variable amount of analyte is present depending on patient samples
c. Standards only need to be within a target range
d. Standards are run to the best estimate of the known value
5. If the confidence interval for most laboratories is 95.5%, what is the acceptable range for
hemoglobin if a hemoglobin control was run with a mean of 12.5 and a standard deviation of 1.0?
a. 9.5 to 12.5
b. 10.5 to 14.5

7. A delta check is a historical reference on samples run in the laboratories. Once a sample fails a delta
check, the most obvious corrective action is to:
a. Verify the identification of the patient sample

population

a. Biological hazards
b. Chemical hazards
c. Environmental hazards
d. All of the above
13. Control materials are:
a. Analyzed concurrently with the unknown samples
b. Substances with a known amount of analyte
c. Used to calibrate the method
d. All of the above
14. Delta checks are used in the hematology laboratory to:
a. Compare past patient results to the current result
b. Verify control accuracy
c. Establish a target range
d. Establish reference ranges for a particular analyte
15. When handwashing after a patient contact, the soap application process should last at least:
a. 5 seconds
b. 15 seconds
c. 20 seconds
