effective elimination of pathogens, including Mycobacterium tuberculosis, which is
more resistant than most viruses and bacteria.

renewed biennially. Licensees receive renewal notices approximately 60 days before
expiration, and continuing education is not currently required for establishment
renewal.

production of new skin cells?
A. Stratum corneum
B. Stratum lucidum
C. Stratum granulosum
D. Stratum basale
CORRECT ANSWER: D. Stratum basale
RATIONALE:The stratum basale, also known as the basal layer, is the deepest layer of
the epidermis and contains keratinocyte stem cells that continuously divide to produce
new skin cells. These cells migrate upward through the epidermal layers, undergoing
differentiation until they reach the stratum corneum and are shed.

item is REQUIRED to be provided to the client?

recontamination.
Question 11: Which muscle is primarily responsible for closing the jaw during
chewing?
A. Frontalis
