Answer: True cuticle (dead tissue)
Question 4
What is the function of the hyponychium, and why must a nail technician avoid disrupting it during services?
Answer: The hyponychium is the thickened skin under the free edge of the nail plate that forms a waterproof seal, preventing bacteria and debris from entering the nail bed and causing infection.
Question 5
Why can damage to the nail matrix result in a permanent nail deformity?
Answer: The nail matrix is the only site where new nail cells are produced; any trauma, infection, or chemical damage to the matrix disrupts cell production and can cause lasting ridges, splits, or abnormal shape.
Question 6
What is the first step if a technician draws blood during a service?
Answer: Stop service immediately
Question 7
Which nail condition is characterized by deep horizontal grooves across the nail plate, and what does it indicate about a client's health history?

Question 9
How must a pedicure foot spa be disinfected between clients, and what is the minimum contact time required?
Answer: The foot spa must be drained, all debris scrubbed out with soap and water, and then filled with or wiped down using an EPA-registered disinfectant at the correct dilution for a minimum contact time of 10 minutes between every client.
Question 10
A client shows a dark brown longitudinal streak running the full length of one nail. Why must the nail technician immediately refer this client to a physician?
Answer: A dark longitudinal streak is called melanonychia and may indicate subungual melanoma, a serious form of skin cancer. Because it can be life-threatening, referral to a physician is mandatory before any service.
