The morning medical laboratory scientist (MLS) has come to work and is assigned to urinalysis. The
night shift left urine specimens that were not tested at the workstation. The laboratory aide places
today's urine specimens at the workstation also.
Before beginning the testing, the MLS should:
A. Wipe down the area with soap and water
B. Wipe down the area with an alcohol-based cleaner C. Wipe down the area with a 1:10 bleach
solution
D. Wear gloves so no cleaning is necessary
C. Wipe down the area with a 1:10 bleach solution
The cleaning of workstations is considered a/an
A. Work practice control
B. Environmental control
C. Chemical hygiene control
D. External quality control
A. Work practice control
Urinalysis testing is performed by the MLS. The first task is to:
A. Test all the urines that are marked stat
B. Test two levels of quality control
C. Test the urines that were left previously
,D. Start with a new bottle of urine strips
B. Test two levels of quality control

What does a fully automated analyzer provide that a semiautomated analyzer does not?
A. Specific gravity
B. Chemical analysis
C. Minimal specimen handling
D. Ease of use
C. Minimal specimen handling
A major advantage of a fully automated analyzer versus a semiautomated analyzer is:
A. Quick turnaround
B. Cost
C. Ease of use
D. Walk-away capability
D. Walk-away capability
, In a fully automated analyzer, clarity is measured by:
