CASE STUDIES:

Effect of Transfer, Lifting and Repositioning (TLR) Injury Prevention Program on Musculoskeletal Injury among Direct Care Workers
Timothy R. Black, Syed M. Shah, Angela J. Busch, Judy Metcalfe and Hyun J. Lim

1. In this study, the injury rate denominators (Full Time
    Equivalents or FTEs) were collected at what level?

a. The worker
b. The department
c. The hospital
d. The health region
e. None of the above
2. In this study, using person/time as the injury rate denominator
    would have allowed for better control of which variable?
a. Data collection period
b. Data maturation
c. Exposure to the hazard
d. Repeated injuries
e. None of the above
A Novel Method for Reducing the Number of Agents to be Studied in an Occupational Epidemiologic Study
Jennifer S. Pierce and Nurtan A. Esmen

3. Relative risk and error have similar effects on the sensitivity
    and specificity of the method proposed in this study. True
    or False?

True
False
4. The method proposed in this study is particularly useful when
    the number of agents to which a workforce is exposed is
    approximately equal to the number of "products" to which
    the workforce is exposed. True or False?
True
False
Validity of Diagnostic Computer-Based Air and Forehead Bone Conduction Audiometry
De Wet Swanepoel and Leigh Biagio

5. Air conduction thresholds for the two audiometers corresponded
    within 5dB or less in more than 90% of instances while bone
    conduction thresholds corresponded within 10 dB or less in 92%
    of instances. True or False?

True
False
6. Previous research has demonstrated that air conduction
    thresholds are prone to increased test-retest variability when
    compared to bone conduction thresholds. True or False?
True
False
Assessing Maintenance of Evaporative Cooling Systems in Legionellosis Outbreaks
Kelly M. Rangel, George Delclos, Robert Emery and Elaine Symanski

7. Excess drift from a cooling tower is usually the result of
    misaligned or missing drift eliminators. True or False?

True
False
8. Legionella bacteria cannot become immune to biocide.
    True or False?
True
False
Measurements of Respirable Superabsorbent Polyacrylate (SAP) Dust by Ethanol Derivatization Using Gas Chromatography-Mass Spectrometry (GC-MS) Detection
Paul McCormack, John S. Lemmo, Margaret Macomber, Mark L. Holcomb and Robert Lieckfield, Jr.

9. An important element of the SAP analytical procedure is
    determination of the Esterification Factor. The key consideration
    of the Esterification Factor is that:

a. it is unique to a particular chemical supplier.
b. it varies from Lot to Lot for a particular chemical
          supplier.
c. it is unique to a particular process.
d. it always needs to be done with each set of
          samples collected.
10. The primary advantage of the ethanol derivatization procedure
      over the traditionally used sodium analysis is:
a. that it provides a lower detection limit.
b. that it is an easier analytical procedure.
c. its specificity to acrylate.
d. the required method of analysis within the
          industry.
Biomarkers of Mercury Exposure in Two Eastern Ukraine Cities
Herman Gibb, Cary Haver, Kostj Kozlov, Jose A. Centeno, Vera Jurgenson, Allan Kolker, Kathryn M. Conko, Edward R. Landa and Hanna Xu

11. What is the best biomarker of inorganic and elemental
      mercury exposure?

a. Urine
b. Blood
c. Hair
d. Fingernails
e. Toenails
12. In the current study, what were the two best environmental
      predictors of blood and urinary mercury?
a. vacuum cleaner dust and interior dust wipes
b. vacuum cleaner dust and soil mercury
c. soil mercury and exterior dust wipes
d. interior and exterior dust wipes
Exposure Data from Multi-Application, Multi-Industry Maintenance of Surfaces and Joints Sealed with Asbestos-Containing Gaskets and Packing
Fred Boelter, Catherine Simmons and Paul Hewett

13. The approximate time period for this study stretched from:

a. 1945-1954
b. 1950-1969
c. 1975-1990
d. 1994-2006
14. Highly engineered fluid sealing devices appear to release
      high concentrations of asbestos fibers. True or False?
True
False
