Question 1Infection Control, Sanitation, and Safety

In a nail salon, which item is classified as a single-use supply that must be discarded after one client?

  1. Glass mixing dish
  2. Nail file Correct answer.
  3. Autoclave tray
  4. Metal cuticle pusher

Explanation

Single-use items are porous or low-cost implements that cannot be reliably cleaned and disinfected, such as files, buffers, and wooden sticks. They are discarded after each client rather than reprocessed.

Question 2Infection Control, Sanitation, and Safety

What is the correct first step when cleaning a metal nipper after a service?

  1. Soak it in disinfectant
  2. Scrub it with soap and warm water Correct answer.
  3. Place it in a UV cabinet
  4. Wipe it with a dry towel

Explanation

Cleaning with soap and water physically removes debris, oil, and organic matter before any disinfection step. Disinfectants lose effectiveness when soil remains on the surface of the implement.

Question 3Infection Control, Sanitation, and Safety

Which action best describes the purpose of hand washing with soap and running water before a manicure?

  1. Removing transient microorganisms from the hands Correct answer.
  2. Softening the nail plate for filing
  3. Increasing circulation to the fingertips
  4. Preventing the polish from chipping

Explanation

Hand washing mechanically removes transient microorganisms and soil from the skin, reducing the risk of transferring pathogens to the client. It is a core infection-control practice performed before and after client contact.

Question 4Infection Control, Sanitation, and Safety

A client arrives with an inflamed, swollen cuticle and visible pus. What is the appropriate response for the nail technician?

  1. Proceed and apply an antibacterial polish
  2. Drain the area and continue the service
  3. Decline the service and refer the client to a physician Correct answer.
  4. Wear two pairs of gloves and complete the manicure

Explanation

Signs of infection such as swelling, redness, and pus are outside the technician's scope of practice and must not be treated. The service should be declined and the client referred to a medical professional.

Question 5Infection Control, Sanitation, and Safety

Which type of glove is appropriate for a nail technician during a standard manicure service?

  1. Nitrile gloves Correct answer.
  2. Cotton gloves
  3. Latex gloves with powder
  4. Vinyl gloves for food handling

Explanation

Nitrile gloves are recommended because they resist many salon chemicals and avoid latex allergy concerns. They provide a barrier against bloodborne pathogens and chemicals during services.

Question 6Infection Control, Sanitation, and Safety

After a blood exposure on the skin of the technician, what should be done first?

  1. Apply a bandage over the area
  2. Continue the service and report later
  3. Wash the area with soap and running water Correct answer.
  4. Apply alcohol-free polish to seal the skin

Explanation

Immediate washing with soap and running water is the first step after skin contact with blood or other potentially infectious material. This reduces pathogen exposure before any follow-up reporting or medical evaluation.

Question 7Infection Control, Sanitation, and Safety

Which statement correctly describes the difference between disinfection and sterilization?

  1. Disinfection kills all microbial life; sterilization kills some
  2. Disinfection reduces most pathogens; sterilization destroys all microbial life including spores Correct answer.
  3. Sterilization is only used on porous items
  4. Both terms describe the same process

Explanation

Disinfection destroys most pathogenic microorganisms on inanimate surfaces, while sterilization destroys all microbial life, including bacterial spores. Sterilization is required for items that penetrate the skin.

Question 8Infection Control, Sanitation, and Safety

What is the primary reason for keeping a covered waste container with a lid in the service area?

  1. To contain contaminated waste safely Correct answer.
  2. To store clean towels
  3. To reduce odors from polish
  4. To hold client personal items

Explanation

Covered waste receptacles contain blood-contaminated or soiled items and prevent accidental exposure to staff and clients. They are part of standard infection-control practice in the salon.

Question 9Infection Control, Sanitation, and Safety

A technician uses a disinfectant labeled as effective against tuberculosis, hepatitis B, and HIV. Which class of disinfectant does this describe?

  1. Antiseptic
  2. Sanitizer
  3. Detergent
  4. Hospital-grade disinfectant Correct answer.

Explanation

Hospital-grade disinfectants are registered to kill a broad spectrum of pathogens, including tuberculosis and bloodborne viruses, on inanimate surfaces. This is the level required for reusable salon implements.

Question 10Infection Control, Sanitation, and Safety

Reusable metal implements should be immersed in disinfectant for how long at minimum, according to typical manufacturer instructions?

  1. 30 seconds
  2. 24 hours
  3. 2 minutes
  4. 10 minutes Correct answer.

Explanation

Most hospital-grade disinfectants require about 10 minutes of contact time for the labeled kill claims, though the exact time should follow the product label. Insufficient contact time leaves pathogens viable.

Question 11Infection Control, Sanitation, and Safety

Which practice best prevents cross-contamination between clients when using a nail brush?

  1. Rinsing the brush under cold water between clients
  2. Using the same brush for all clients in one day
  3. Cleaning and disinfecting the brush after each client Correct answer.
  4. Storing the brush in a drawer with clean towels

Explanation

Any reusable implement, including brushes, must be cleaned and then disinfected between clients to prevent transfer of microorganisms. Rinsing alone does not achieve disinfection.

Question 12Infection Control, Sanitation, and Safety

What does the term standard precautions mean in a nail salon setting?

  1. Using precautions only with visibly ill clients
  2. Treating every client as potentially infectious Correct answer.
  3. Wearing gloves only when the client requests it
  4. Sterilizing every surface after each service

Explanation

Standard precautions require treating all blood, body fluids, and potentially infectious materials as if infectious, regardless of the client's appearance. This approach protects both technician and client.

Question 13Infection Control, Sanitation, and Safety

A bottle of disinfectant has been diluted and left in an open container for several days. What is the best action?

  1. Use it because it still looks clear
  2. Discard it and prepare a fresh solution Correct answer.
  3. Add more concentrate to the container
  4. Store it in direct sunlight

Explanation

Diluted disinfectants lose potency over time and when exposed to air or light, so they must be prepared fresh according to the label. Using an expired solution gives a false sense of protection.

Question 14Infection Control, Sanitation, and Safety

Which statement about porous vs non-porous surfaces is most accurate for infection control?

  1. Non-porous surfaces can generally be cleaned and disinfected more effectively Correct answer.
  2. Porous surfaces never harbor microorganisms
  3. Both types require sterilization
  4. Porous surfaces are easier to disinfect

Explanation

Non-porous surfaces such as metal and glass can be effectively cleaned and disinfected because liquids do not penetrate them. Porous items absorb fluids and are often single-use.

Question 15Infection Control, Sanitation, and Safety

A technician notices a crack in the handle of a reusable metal pusher. What should be done?

  1. Clean it and return it to the drawer
  2. Cover the crack with tape
  3. Discard it because cracks harbor pathogens Correct answer.
  4. Continue using it until it breaks

Explanation

Cracks and crevices cannot be reliably cleaned and disinfected, so damaged implements must be discarded. This prevents trapped debris and microorganisms from reaching clients.

Question 16Infection Control, Sanitation, and Safety

Which of the following is the correct sequence for reprocessing reusable implements?

  1. Store, clean, disinfect, rinse
  2. Rinse, store, disinfect, clean
  3. Clean, rinse, dry, disinfect, store Correct answer.
  4. Disinfect, clean, dry, store

Explanation

Implements must be cleaned and rinsed to remove debris, dried, then fully immersed in disinfectant for the labeled contact time before storage. Disinfection before cleaning is ineffective because soil blocks the disinfectant.

Question 17Infection Control, Sanitation, and Safety

A salon uses an autoclave. Which items are appropriate for sterilization in it?

  1. Cotton balls
  2. Metal nippers and cuticle scissors Correct answer.
  3. Wooden orange sticks
  4. Plastic nail files

Explanation

Autoclaves use steam under pressure and are suitable for heat-stable metal implements such as nippers and scissors. Single-use porous items are discarded rather than sterilized.

Question 18Infection Control, Sanitation, and Safety

What is the main infection-control concern with a whirlpool foot spa that is not properly cleaned between clients?

  1. Increased polish drying time
  2. Reduced water temperature
  3. Faster nail growth
  4. Biofilm buildup in internal tubing Correct answer.

Explanation

Internal tubing and jets in whirlpool spas can harbor biofilm, a protective layer of microorganisms that is difficult to remove. Without proper cleaning and disinfection, pathogens can be released into the water.

Question 19Infection Control, Sanitation, and Safety

A technician develops a latex sensitivity. Which adjustment best supports continued safe practice?

  1. Avoid all client contact
  2. Wear cotton gloves under latex
  3. Use powdered latex gloves
  4. Switch to nitrile or other non-latex gloves Correct answer.

Explanation

Switching to non-latex gloves such as nitrile prevents further allergic reactions while maintaining barrier protection. Powdered latex can worsen sensitivity and is not recommended.

Question 20Infection Control, Sanitation, and Safety

Which situation requires the highest level of reprocessing, namely sterilization, rather than disinfection?

  1. A file used on natural nails
  2. A nipper that may contact blood during a pedicure Correct answer.
  3. A towel used to dry hands
  4. A plastic buffer used on the nail plate

Explanation

Implements that may contact blood or penetrate skin are critical items and require sterilization to destroy all microbial life, including spores. Routine disinfection is insufficient for these items.

Question 21Infection Control, Sanitation, and Safety

A technician reads a disinfectant label stating it is effective against mycobacterium tuberculosis. Why is this claim relevant to salon practice?

  1. It indicates the product is a sanitizer
  2. It shows the product meets a high-level kill standard for hard-to-kill organisms Correct answer.
  3. It proves the product sterilizes
  4. It means the product is safe on skin

Explanation

A tuberculocidal claim indicates the disinfectant can kill a hardy organism, which generally reflects a higher-level disinfectant suitable for salon implements. It does not mean the product sterilizes or is safe on skin.

Question 22Infection Control, Sanitation, and Safety

A client reports a fungal nail infection. Which response best reflects appropriate infection-control practice?

  1. Apply a base coat and continue the service
  2. File the nail more aggressively to remove the fungus
  3. Treat the nail with an over-the-counter antifungal and proceed
  4. Refuse the service and refer the client to a physician Correct answer.

Explanation

Fungal infections are contagious and outside the technician's scope of treatment, so the service should be declined and the client referred to a physician. Performing services risks spreading infection and harming the client.

Question 23Infection Control, Sanitation, and Safety

Which combination of practices best reduces the risk of transferring bloodborne pathogens during a pedicure?

  1. Gloves, hand hygiene, and disinfected implements Correct answer.
  2. Gloves alone
  3. Hand hygiene alone
  4. Disinfected implements alone

Explanation

Effective infection control requires multiple layers: gloves as a barrier, hand hygiene to remove transient organisms, and properly disinfected implements. Relying on any single measure leaves gaps in protection.

Question 24Infection Control, Sanitation, and Safety

A technician must choose between two disinfectants: one is labeled for hospital use with a 10-minute contact time, and the other is a general-purpose cleaner. Which choice is appropriate for reusable nippers?

  1. Either product, because both clean the tool
  2. The general-purpose cleaner, because it is gentler
  3. The hospital-grade disinfectant used for the full contact time Correct answer.
  4. The cleaner, if the nippers are rinsed afterward

Explanation

Reusable implements require a hospital-grade disinfectant used for the full labeled contact time to achieve the claimed kill. A general-purpose cleaner removes soil but does not reliably kill pathogens.

Question 25Infection Control, Sanitation, and Safety

A salon's written infection-control plan should include which element to be considered complete?

  1. A list of client birthdays
  2. Procedures for cleaning, disinfection, and exposure response Correct answer.
  3. A price list for services
  4. A schedule of staff vacations

Explanation

A complete infection-control plan documents cleaning and disinfection procedures, staff training, and the response to exposures. This ensures consistent practice and supports regulatory compliance.

Question 26Infection Control, Sanitation, and Safety

A technician is about to begin a manicure on a client with no visible cuts or illness. Which action reflects correct hand-hygiene practice before gloving or starting the service?

  1. Wipe hands with a towel used earlier in the day
  2. Apply lotion to the hands and begin the service
  3. Rinse hands briefly in the disinfectant used for implements
  4. Wash hands with soap and water or use an alcohol-based hand rub, then dry thoroughly Correct answer.

Explanation

Hand hygiene before every client service removes transient microorganisms and is the single most effective routine practice for reducing transmission in the salon. Soap and water or an alcohol-based hand rub are both acceptable when hands are not visibly soiled, and hands should be dried before continuing.

Question 27Infection Control, Sanitation, and Safety

A technician is setting up a pedicure station. Which item may be reused between clients after cleaning and disinfection rather than being discarded?

  1. A disposable toe separator
  2. A single-use nail file
  3. A reusable stainless steel nipper Correct answer.
  4. A porous foam buffer

Explanation

Reusable implements made of hard, non-porous material such as stainless steel can be cleaned and then disinfected with an appropriate product and reused. Single-use and porous items cannot be reliably cleaned and disinfected and must be discarded after one client.

Question 28Infection Control, Sanitation, and Safety

A technician has finished a service and is cleaning a reusable metal implement. According to standard reprocessing steps, what must happen before the implement is placed into the disinfectant solution?

  1. It should be wiped with a paper towel and stored in a drawer until the end of the day
  2. It should be placed directly into the disinfectant while still wet with product residue
  3. It should be rinsed in hot water only, with no detergent used
  4. It should be scrubbed with a clean brush and detergent to remove all visible debris, then rinsed and dried Correct answer.

Explanation

Disinfectants work only on surfaces that are free of organic matter and product residue, so the item must be cleaned with detergent, rinsed, and dried before immersion. Skipping cleaning leaves a biofilm that shields microorganisms and inactivates many disinfectants.

Question 29Infection Control, Sanitation, and Safety

A client arrives for a manicure with a small, red, crusted sore on one finger near the nail. The technician has no gloves on. What is the most appropriate immediate action?

  1. Apply a bandage to the sore and continue the manicure without gloves
  2. Put on gloves, avoid the lesion, and refer the client to a health care provider before service Correct answer.
  3. Proceed with the service but avoid touching the sore finger
  4. Refuse to serve the client and ask the client to leave immediately

Explanation

Standard precautions treat all clients as potentially infectious, so the technician should don gloves and avoid contact with a lesion that could be contagious. A suspicious sore should be evaluated by a health care provider before the service continues, and the client should be referred rather than treated.

Question 30Infection Control, Sanitation, and Safety

A technician is evaluating a disinfectant for use on reusable metal implements. The label states a 10-minute contact time and lists tuberculocidal activity. Which conclusion is best supported by this label information?

  1. The product sterilizes implements because it kills mycobacterium
  2. The product is unsuitable because tuberculocidal products are too harsh for salon metals
  3. The product requires a shorter contact time than the label states
  4. The product meets the criteria for a hospital-grade disinfectant and can be used if the manufacturer's instructions are followed Correct answer.

Explanation

A tuberculocidal claim indicates the product is an EPA-registered hospital-grade disinfectant, which is the level appropriate for reusable salon implements when used per label directions. The listed contact time must be observed exactly, and the product must be used at the labeled dilution.

Question 31Anatomy and Physiology of the Hands, Arms, and Nails

Which layer of the nail plate is the thickest and provides most of its structural strength?

  1. The intermediate layer Correct answer.
  2. The ventral layer
  3. The hyponychium
  4. The dorsal layer

Explanation

The nail plate is built from three horizontal layers, and the intermediate (middle) layer is by far the thickest. It supplies most of the plate's rigidity and strength, while the thin dorsal and ventral layers contribute comparatively little. Understanding this layering helps a technician judge how much filing pressure the plate can tolerate.

Question 32Anatomy and Physiology of the Hands, Arms, and Nails

The living skin that seals the gap between the free edge of the nail and the fingertip is called the:

  1. Lunula
  2. Eponychium
  3. Nail matrix
  4. Hyponychium Correct answer.

Explanation

The hyponychium is the skin fold located beneath the free edge where the nail separates from the fingertip. It forms a protective seal that helps keep dirt and microbes from entering the space under the plate. The eponychium and lunula sit at the opposite, proximal end of the nail.

Question 33Anatomy and Physiology of the Hands, Arms, and Nails

Which structure is the actively growing part of the nail that produces new plate cells?

  1. Nail wall
  2. Nail bed
  3. Nail groove
  4. Nail matrix Correct answer.

Explanation

The nail matrix is the generative tissue that manufactures keratinized cells which become the nail plate. It sits beneath the proximal nail fold and extends partly under the lunula. Damage to the matrix can permanently alter the shape or thickness of the growing nail.

Question 34Anatomy and Physiology of the Hands, Arms, and Nails

The nail plate itself is composed mainly of which protein?

  1. Keratin Correct answer.
  2. Elastin
  3. Collagen
  4. Melanin

Explanation

The nail plate is made of tightly packed, flattened cells filled with keratin, a tough fibrous protein. Keratin gives the plate its hardness and resistance to wear. Collagen and elastin are found in the surrounding skin and connective tissue, not as the primary plate material.

Question 35Anatomy and Physiology of the Hands, Arms, and Nails

The visible pale, half-moon-shaped area at the base of the nail plate is the:

  1. Lunula Correct answer.
  2. Free edge
  3. Nail fold
  4. Cuticle

Explanation

The lunula is the whitish crescent seen at the proximal end of the nail plate. Its paler appearance results from the thicker, less translucent cells overlying the matrix in that region. It is a normal landmark rather than a sign of disease.

Question 36Anatomy and Physiology of the Hands, Arms, and Nails

Which bones form the visible framework of the fingers and support the nails?

  1. Carpals
  2. Radius and ulna
  3. Phalanges Correct answer.
  4. Metacarpals

Explanation

The fingers are built from the phalanges, the small bones of the digits, which give the fingers their shape and support the nail structures. The metacarpals form the palm, while carpals make up the wrist. Knowing this anatomy helps a technician understand fingertip structure and safety.

Question 37Anatomy and Physiology of the Hands, Arms, and Nails

A technician notices that a client's nail plate curves strongly downward at the sides, forming a deep C-shape. Which natural variation does this most likely reflect?

  1. A disorder of the hyponychium
  2. A sign that the matrix has stopped producing cells
  3. A normal strong lateral curvature of the nail plate Correct answer.
  4. A normal reduction in plate thickness

Explanation

Many clients naturally have a pronounced lateral curvature, giving the plate a deep C-shaped cross-section. This is a normal structural variation and does not by itself indicate disease. The technician should account for it when shaping and when fitting product.

Question 38Anatomy and Physiology of the Hands, Arms, and Nails

During a manicure, a client reports tenderness when pressure is applied just under the free edge. Which structure is most directly involved in this sensation?

  1. The lunula
  2. The dorsal layer
  3. The hyponychium Correct answer.
  4. The nail plate

Explanation

The hyponychium is living, nerve-rich tissue beneath the free edge, so pressure there can be painful. The nail plate and its layers are keratinized and lack nerve endings. A technician should therefore avoid probing or filing aggressively under the free edge.

Question 39Anatomy and Physiology of the Hands, Arms, and Nails

The proximal nail fold protects which underlying structure most directly?

  1. The free edge
  2. The hyponychium
  3. The nail matrix Correct answer.
  4. The distal phalanx tip

Explanation

The proximal nail fold is the skin fold that overlaps the base of the nail and shields the underlying matrix from injury and infection. Because the matrix produces the plate, protecting this area is important for normal nail growth. Aggressive cuticle work in this region can damage the seal and the matrix.

Question 40Anatomy and Physiology of the Hands, Arms, and Nails

A client's nails grow slowly and appear thin. Which factor most plausibly explains reduced nail growth rate?

  1. Increased blood flow to the matrix
  2. A longer free edge
  3. Reduced circulation or nutrition reaching the matrix Correct answer.
  4. A thicker dorsal layer

Explanation

Nail growth depends on the matrix receiving adequate blood supply and nutrients. Poor circulation, illness, or nutritional deficiency can slow cell production and yield thinner, slower-growing nails. The dorsal layer thickness and free edge length do not drive growth rate.

Question 41Anatomy and Physiology of the Hands, Arms, and Nails

Which statement best describes the relationship between the nail bed and the nail plate?

  1. The bed is the pigmented half-moon at the base
  2. The plate rests on and is guided by the bed as it grows forward Correct answer.
  3. The bed is the skin seal under the free edge
  4. The bed generates new plate cells that replace the matrix

Explanation

The nail bed is the tissue on which the plate rests, and it helps guide the plate forward as it grows. It supports the plate but does not replace the matrix as the source of new cells. The lunula and hyponychium are separate structures.

Question 42Anatomy and Physiology of the Hands, Arms, and Nails

A technician is shaping a nail and wants to avoid thinning the plate excessively. Which layer should be preserved as much as possible to maintain strength?

  1. The nail groove
  2. The hyponychium
  3. The ventral layer
  4. The intermediate layer Correct answer.

Explanation

The intermediate layer carries most of the plate's structural strength, so over-filing it weakens the nail. Preserving this layer helps maintain durability during shaping and product application. The ventral layer is thin, while the hyponychium and groove are not plate layers.

Question 43Anatomy and Physiology of the Hands, Arms, and Nails

The lateral nail folds on either side of the nail primarily serve to:

  1. Produce new nail plate cells
  2. Supply pigment to the nail
  3. Guide and border the sides of the growing plate Correct answer.
  4. Seal the space under the free edge

Explanation

The lateral nail folds are the skin folds along each side of the nail that border and guide the plate as it grows forward. They help keep the plate aligned within its groove. They do not generate plate cells, seal the free edge, or provide pigment.

Question 44Anatomy and Physiology of the Hands, Arms, and Nails

Which observation most strongly suggests that a nail's matrix has been injured?

  1. A slightly deeper C-curve on one finger
  2. A single white spot that grows out with the nail
  3. A short free edge on one finger
  4. A persistent ridge or groove that travels with the growing plate Correct answer.

Explanation

Because the matrix produces the plate, localized matrix injury can leave a permanent ridge or groove that moves outward as the nail grows. A white spot that grows out is typically a minor, temporary finding. Curvature and free edge length are normal variations.

Question 45Anatomy and Physiology of the Hands, Arms, and Nails

A client asks why pressing on the nail plate itself causes little pain compared with pressing the surrounding skin. Which explanation is most accurate?

  1. The plate contains many nerve endings but they are inactive
  2. The plate is supplied by the hyponychium
  3. The plate is protected by the lunula
  4. The plate is keratinized tissue without nerve endings Correct answer.

Explanation

The nail plate is composed of hardened, keratinized cells and has no nerve endings, so pressure on it is largely painless. The surrounding skin and structures such as the hyponychium are innervated and sensitive. This distinction guides safe handling during services.

Question 46Anatomy and Physiology of the Hands, Arms, and Nails

Which combination correctly pairs a hand bone with its location?

  1. Phalanges - wrist
  2. Metacarpals - palm Correct answer.
  3. Radius - palm
  4. Carpals - fingers

Explanation

The metacarpals are the long bones that form the palm, connecting the wrist to the fingers. The carpals make up the wrist, the phalanges form the fingers, and the radius is a forearm bone. Correct pairing of bone to location supports safe and informed hand care.

Question 47Anatomy and Physiology of the Hands, Arms, and Nails

A client's nail plate shows a deep longitudinal groove running from the base to the free edge on one finger. Which interpretation is most consistent with nail anatomy?

  1. The groove is caused by a thicker dorsal layer
  2. The groove reflects a localized matrix disturbance that moved outward with growth Correct answer.
  3. The groove shows the lunula has enlarged
  4. The groove indicates the hyponychium is overgrown

Explanation

A longitudinal groove that extends the length of the plate typically arises from a localized disturbance in the matrix, with the defect carried forward as the nail grows. Its linear path reflects the direction of growth. Hyponychium overgrowth, dorsal thickness, and lunula size do not produce this pattern.

Question 48Anatomy and Physiology of the Hands, Arms, and Nails

Which statement about the blood supply of the nail unit is most accurate?

  1. Blood reaches the nail only through the hyponychium
  2. The nail plate has its own direct blood vessels
  3. The matrix and bed are supplied by small vessels that support growth and health Correct answer.
  4. The lunula is avascular and receives no blood

Explanation

The matrix and nail bed are richly supplied by small blood vessels that deliver oxygen and nutrients needed for cell production and maintenance. The plate itself is not vascularized. The lunula and hyponychium are part of the living nail unit and are supplied by this network.

Question 49Anatomy and Physiology of the Hands, Arms, and Nails

A technician compares two clients: one has a pronounced lunula, the other a barely visible one. What is the most reasonable conclusion?

  1. An invisible lunula proves the matrix is missing
  2. The visible lunula varies among individuals and is not by itself a sign of disease Correct answer.
  3. Lunula size is fixed by the free edge length
  4. A visible lunula always indicates matrix damage

Explanation

The lunula's visibility depends on factors such as the thickness of overlying tissue and individual variation, so its prominence differs widely among healthy people. A visible or hidden lunula alone is not diagnostic of disease. The technician should avoid drawing medical conclusions from this feature.

Question 50Anatomy and Physiology of the Hands, Arms, and Nails

Which sequence correctly describes the path a new nail cell takes from origin to visible plate?

  1. Nail bed → matrix → lunula → free edge
  2. Matrix → plate → bed → free edge
  3. Hyponychium → matrix → plate → free edge
  4. Matrix → nail plate → free edge Correct answer.

Explanation

New cells are produced in the matrix, become part of the nail plate, and are pushed forward until they reach the free edge. The bed supports the plate along the way but is not a stage in the cell's path. The hyponychium lies at the distal end and is not the origin of new cells.
