1. Which of the following nail disorders is characterized by a dramatically
increased forward curvature of the nail plate, often caused by injury to the
matrix or an inherited trait? A) Onycholysis B) Onychophagy C) Plicatured
nail D) Onychogryphosis C) Plicatured nail Rationale: A plicatured nail, also
known as a folded nail, is a type of highly curved nail plate often caused
by injury to the matrix or inherited genetics. This condition can lead to
ingrown nails and requires careful filing and maintenance. Onycholysis is
the separation of the nail plate from the bed, onychophagy refers to bitten
nails, and onychogryphosis is a severe enlargement and thickening of the
nails, commonly known as ram's horn nails.
2. What is the technical term for the nail bed, the living skin upon which the
nail plate sits? A) Eponychium B) Matrix C) Hyponychium D) Onyx B) Matrix
(Wait, the nail bed is the skin upon which the nail plate sits. The matrix is
where the nail is formed. Let's correct this.) Let's re-do 2.
3. What is the living skin that supports the nail plate as it grows toward the
free edge? A) Eponychium B) Hyponychium C) Nail bed D) Matrix C) Nail
bed Rationale: The nail bed is the portion of living skin that supports the
nail plate as it grows out toward the free edge. It is richly supplied with
blood vessels and nerves. The matrix is the area where the nail plate cells
are formed; the eponychium is the living skin at the base of the natural
nail plate covering the matrix area; and the hyponychium is the slightly
thickened layer of skin that lies between the fingertip and the free edge of
the nail plate.
,4. Which specialized organelle or structure forms the hardened keratin plate
that constitutes the visible fingernail or toenail? A) Bed epithelium B)
Matrix C) Cuticle D) Lunula B) Matrix Rationale: The matrix is the section of
the nail follicle that contains lymph, blood vessels, and nerves, and is
responsible for creating the nail plate cells through mitosis. The health
and size of the matrix determine the thickness and shape of the natural
nail plate. The bed epithelium guides the nail plate along the bed, the
cuticle is dead tissue attached to the plate, and the lunula is the visible
part of the matrix.
5. When performing a salon service, what level of decontamination is required
for metal implements such as nippers and pushers? A) Sanitation B)
Antiseptic application C) Disinfection D) Sterilization C) Disinfection
Rationale: Disinfection is the chemical process that destroys most, but not
all, harmful organisms on environmental surfaces, and it is the mandatory
standard standard for non-porous salon implements like nippers.
Sanitation or cleaning is merely the removal of visible debris and lowering
the number of germs. Antiseptics are designed for use on living skin.
Sterilization destroys all microbial life, including spores, but is typically
reserved for critical medical devices or specific advanced protocols rather
than everyday state-mandated standard salon disinfection.
6. Which of the following is an EPA-registered disinfectant that must be used
according to manufacturer instructions to effectively clean non-porous
tools? A) Isopropyl alcohol 70% B) Quaternary ammonium compounds C)
Hydrogen peroxide 3% D) Sodium hypochlorite at 2% dilution B) Quaternary
ammonium compounds Rationale: Quaternary ammonium compounds,
commonly known as quats, are advanced, fast-acting disinfectants
designed for use on non-porous surfaces in salons and are EPA-registered
for this purpose. Alcohol at 70% is primarily an antiseptic or low-level
sanitizing agent and evaporates too quickly to meet contact-time
requirements for broad-spectrum disinfection. Hydrogen peroxide 3% is
too weak for surface disinfection requirements, and proper salon-grade
bleach requires specific high-strength regulations.
, 7. What type of bacteria is harmless or even beneficial to human life, making
up the majority of bacteria found in nature? A) Pathogenic B)
Nonpathogenic C) Spirilla D) Staphylococci B) Nonpathogenic Rationale:
Nonpathogenic bacteria are harmless organisms that may perform useful
functions, such as breaking down food in the digestive tract or protecting
against infection. Pathogenic bacteria are harmful microorganisms that
can cause disease or infection when they invade the body. Spirilla and
staphylococci are specific types of pathogenic bacteria.
8. What part of the nail anatomy acts as a protective barrier, preventing
microscopic pathogens from invading and infecting the nail matrix? A)
Perionychium B) Free edge C) Eponychium D) Hyponychium C) Eponychium
Rationale: The eponychium is the living skin at the base of the natural nail
plate that covers the matrix area and forms an essential seal against
moisture and pathogenic organisms. The free edge is the part of the nail
that extends past the finger. The hyponychium protects the nail bed under
the free edge, and the perionychium is the tissue surrounding the entire
nail border.
9. What substance is a tough, fibrous protein found in the nail plate, hair, and
skin, giving the nail its strength and rigidity? A) Collagen B) Elastin C) Keratin
D) Melanin C) Keratin Rationale: Keratin is the primary protein that makes
up the nail plate, hair, and outer layers of skin. It is composed of amino
acids and contains sulfur, which creates the cross-links that give the nail
plate its structural resilience. Collagen and elastin are structural proteins
found in the dermis layer of the skin, while melanin is the pigment
responsible for skin and hair color.
10.An infection of the tissue surrounding the nail, characterized by redness,
swelling, and tenderness, is medically known as which of the following? A)
Tinea pedis B) Onychia C) Paronychia D) Onychoptosis C) Paronychia
Rationale: Paronychia is a bacterial inflammation of the tissues
surrounding the nail, commonly presenting with redness, swelling, and
pain along the nail fold. Tinea pedis refers to fungal infections of the foot
