Question 1Professional practice, ethics, and client care

A client arrives at a beauty salon with a note from their doctor stating they are taking isotretinoin (Roaccutane). Which action best reflects safe professional practice for a facial treatment?

  1. Decline skin treatments that could damage the fragile skin and advise the client to return after the course ends and a waiting period has passed Correct answer.
  2. Proceed with a gentle facial but avoid all exfoliation and waxing
  3. Perform the treatment only if the client signs a disclaimer releasing the therapist from liability
  4. Carry out the facial as normal but reduce the massage time by half

Explanation

Isotretinoin markedly thins the skin and impairs healing, so waxing, exfoliation and aggressive facial work can cause tearing or scarring. Professional practice is to postpone such treatments until the medication has been stopped for the medically advised interval, and a signed disclaimer does not transfer the therapist's duty of care.

Question 2Professional practice, ethics, and client care

Which document primarily protects a beauty client's personal and treatment information from being shared without consent?

  1. The salon's price list
  2. The therapist's professional indemnity certificate
  3. The manufacturer's product safety data sheet
  4. The data protection or privacy policy governing client records Correct answer.

Explanation

Client records, including health details and treatment history, are personal data and are governed by data protection or privacy legislation reflected in the salon's privacy policy. Consent, secure storage and controlled access all flow from that framework.

Question 3Professional practice, ethics, and client care

Before beginning a first-time lash tint, what is the most appropriate way to check for a reaction to the product?

  1. Ask the client whether they have ever reacted to hair dye
  2. Perform a patch test on a small area at least 24 to 48 hours before the appointment, following the manufacturer's instructions Correct answer.
  3. Apply the full tint and observe the client for ten minutes afterwards
  4. Read the product label aloud to the client and record their verbal agreement

Explanation

A patch test applies a small amount of product to check sensitisation before full exposure, and it must be done within the timeframe specified by the manufacturer, commonly 24 to 48 hours ahead. This is a standard precaution for tinting and dyeing services and should be recorded in the client's notes.

Question 4Professional practice, ethics, and client care

A new client discloses during consultation that she is 14 weeks pregnant. Which approach is most consistent with professional client care for a routine facial?

  1. Proceed with a comfortable treatment while avoiding contraindicated products and techniques, and document the disclosure Correct answer.
  2. Refuse all treatment until after the birth
  3. Treat as normal but use stronger products to compensate for hormonal skin changes
  4. Refer the client to a doctor and take no further part in her care

Explanation

Pregnancy is not an automatic bar to gentle beauty treatments, but certain products and techniques, such as some essential oils or strong electrical treatments, should be avoided. The therapist should adapt the service, obtain consent and record the disclosure accurately.

Question 5Professional practice, ethics, and client care

What is the primary purpose of keeping a signed consultation record for every client?

  1. To advertise the salon's thoroughness to prospective clients
  2. To provide evidence of the agreed service, disclosed health information and informed consent Correct answer.
  3. To calculate the therapist's commission each month
  4. To satisfy product suppliers that stock is being used

Explanation

Consultation records document the client's health disclosures, the treatment agreed and the consent given, which supports continuity of care and provides a defensible record if a concern arises later. They are a professional and often legal requirement, not a marketing or accounting tool.

Question 6Professional practice, ethics, and client care

A client repeatedly asks a therapist to perform a treatment that the therapist believes is clinically unsuitable for the client's skin condition. What is the most professional response?

  1. Explain the reasoning, offer a suitable alternative and decline the unsuitable service if the client insists Correct answer.
  2. Carry out the treatment because the client is paying for it
  3. Ask another therapist to perform it without sharing the concern
  4. Perform the treatment but note on the record that the client ignored advice

Explanation

The therapist's professional judgement and duty of care take precedence over a client's request for an unsuitable service. Explaining the risk, offering an alternative and, if necessary, declining protects the client and maintains professional integrity.

Question 7Professional practice, ethics, and client care

Which practice best demonstrates respect for client dignity during a body waxing treatment?

  1. Chatting loudly with colleagues to make the atmosphere feel relaxed
  2. Leaving the door open so the client does not feel enclosed
  3. Allowing other clients to observe so they know what to expect
  4. Keeping the treatment area covered except where being worked on and explaining each step Correct answer.

Explanation

Draping and minimal exposure protect the client's privacy and dignity, and explaining each step maintains informed consent and reduces anxiety. These measures are fundamental to professional client care in intimate treatments.

Question 8Professional practice, ethics, and client care

A therapist develops a close friendship with a long-standing client. Which boundary issue is most relevant to professional practice?

  1. Friendship always improves treatment outcomes, so no boundary applies
  2. The therapist should avoid letting the friendship compromise objectivity, confidentiality or fair pricing Correct answer.
  3. The therapist may share other clients' personal stories as a sign of trust
  4. The therapist should stop recording consultations because the relationship is now informal

Explanation

Professional boundaries require that personal relationships do not distort clinical judgement, confidentiality or fair treatment. Warmth is appropriate, but the therapist must still maintain records, protect other clients' information and apply consistent pricing and standards.

Question 9Professional practice, ethics, and client care

What does informed consent for a beauty treatment require?

  1. A signature collected by reception without any discussion
  2. A verbal agreement given after the treatment is finished
  3. The client understanding the nature, benefits, risks and alternatives before agreeing to proceed Correct answer.
  4. Payment of a deposit before the consultation

Explanation

Informed consent means the client has received and understood relevant information about the service, its benefits, risks and alternatives, and has freely agreed before it begins. A signature is only meaningful when it follows that discussion.

Question 10Professional practice, ethics, and client care

During a massage, a client becomes pale, clammy and dizzy. What is the most appropriate immediate action?

  1. Finish quickly so the client can leave and rest at home
  2. Apply a warming mask to stimulate circulation
  3. Stop the treatment, help the client into a safe position, ensure fresh air and monitor them Correct answer.
  4. Continue the massage but talk more to distract the client

Explanation

Pallor, clamminess and dizziness suggest a vasovagal or hypotensive reaction, so the priority is to stop the treatment, position the client safely, ensure air and monitor their condition. Emergency help should be sought if symptoms do not resolve or worsen.

Question 11Professional practice, ethics, and client care

Which action best demonstrates correct hand hygiene before a treatment?

  1. Washing with soap and water or using an alcohol-based hand rub, including between the fingers, and drying thoroughly Correct answer.
  2. Wiping hands on a clean towel without washing
  3. Rinsing hands briefly in cold water
  4. Applying hand cream and proceeding directly to the client

Explanation

Effective hand hygiene involves thorough cleansing with soap and water or an alcohol-based rub, covering all surfaces including between the fingers, followed by proper drying. This reduces the transmission of microorganisms to clients and surfaces.

Question 12Professional practice, ethics, and client care

A therapist notices a small, weeping lesion on a client's skin near the treatment area. What is the most appropriate course of action?

  1. Avoid the area, treat only healthy skin if safe, and advise the client to seek medical advice about the lesion Correct answer.
  2. Proceed as normal because skin lesions are common
  3. Pop the lesion and sanitise the area
  4. Cover it with a plaster and treat over the top

Explanation

An unidentified weeping lesion may be infectious, so it should not be covered and treated over, which can spread contamination. The therapist should avoid the area, work only on healthy skin where safe, and recommend medical assessment.

Question 13Professional practice, ethics, and client care

Which statement correctly describes the role of professional indemnity insurance for a beauty specialist?

  1. It covers only equipment breakdown in the salon
  2. It guarantees that a therapist will never face a complaint
  3. It replaces the need for safe working practices
  4. It provides cover for claims of injury or negligence arising from treatments within the therapist's competence Correct answer.

Explanation

Professional indemnity insurance protects the therapist against claims arising from professional services, but it does not replace safe practice or competence. Cover usually depends on working within the scope of training and following recognised procedures.

Question 14Professional practice, ethics, and client care

A client asks the therapist to recommend a specific serum for a medical skin condition. How should the therapist respond?

  1. Tell the client that all serums will cure the condition
  2. Diagnose the condition and prescribe the strongest available serum
  3. Refuse to discuss skincare entirely
  4. Recommend general cosmetic options within the therapist's training and advise the client to consult a medical professional for the condition Correct answer.

Explanation

Beauty specialists work within a defined scope of practice and must not diagnose or treat medical conditions. They can offer cosmetic guidance within their training while directing the client to an appropriate medical professional for diagnosis and treatment.

Question 15Professional practice, ethics, and client care

Which behaviour would most likely constitute a breach of professional ethics in a beauty setting?

  1. Guaranteeing a permanent cure for a skin condition to secure a booking Correct answer.
  2. Recording consent before a treatment
  3. Recommending a colleague whose skills better suit the client's needs
  4. Declining to treat a client with an active skin infection

Explanation

Guaranteeing a permanent cure is misleading and raises false expectations, which breaches ethical and often legal standards of honest advertising. Declining unsafe treatments and making appropriate referrals are both ethical behaviours.

Question 16Professional practice, ethics, and client care

A salon wants to use before-and-after photographs of a client on social media. What is required before publishing them?

  1. Removal of the client's name so consent becomes unnecessary
  2. Approval from the product manufacturer
  3. Written consent from the client specifying how the images will be used Correct answer.
  4. Nothing, because the photos were taken in the salon

Explanation

Photographs of clients are personal data and their use for marketing requires explicit, informed consent covering the intended purpose and platform. Anonymising images may reduce but does not automatically remove the need for consent.

Question 17Professional practice, ethics, and client care

Which of the following best describes the correct way to store and dispose of used wax spatulas during a treatment?

  1. Wipe the spatula on a towel and reuse it on the same client
  2. Return the spatula to the wax pot after each application
  3. Use a single spatula only once and discard it, using a fresh one for each application Correct answer.
  4. Dip the spatula in the wax and then in a sanitiser before reuse

Explanation

Double-dipping a used spatula contaminates the wax pot and can transfer microorganisms between clients. Single-use spatulas, discarded after each application, are the accepted standard for hygiene.

Question 18Professional practice, ethics, and client care

A client with a known allergy to a specific fragrance oil requests a treatment using a product that contains it. What is the most appropriate response?

  1. Proceed and monitor for a reaction during the treatment
  2. Use the product because the concentration is low
  3. Dilute the product with water before applying
  4. Select a fragrance-free alternative and confirm the ingredients with the client Correct answer.

Explanation

A known allergy is an absolute contraindication for that ingredient, and low concentration or dilution does not make exposure safe. Choosing an alternative and checking ingredients respects the client's health and informed choice.

Question 19Professional practice, ethics, and client care

What is the main reason for maintaining a clean, uncluttered treatment room with surfaces disinfected between clients?

  1. To allow faster turnover of appointments
  2. To reduce the risk of cross-infection and support professional standards of care Correct answer.
  3. To comply with product manufacturer warranties
  4. To make the salon look attractive in photographs

Explanation

Cleaning and disinfecting surfaces between clients reduces the transmission of microorganisms and demonstrates a professional duty of care. Appearance and efficiency are secondary benefits, not the primary rationale.

Question 20Professional practice, ethics, and client care

A therapist is asked by a colleague to treat a client using a machine the therapist has not been trained to operate. What is the most professional action?

  1. Use the machine at a lower setting to reduce the risk
  2. Decline and explain that competence requires proper training, offering to refer the client to a trained colleague Correct answer.
  3. Ask the client to sign a waiver and proceed
  4. Operate the machine carefully after reading the manual once

Explanation

Working within one's training and competence is a core professional obligation, and operating unfamiliar equipment risks harm to the client and liability for the therapist. Declining and referring to a trained colleague protects everyone involved.

Question 21Health, safety, and hygiene in the salon

In a beauty salon, which practice best breaks the chain of cross-contamination between clients when performing a manicure?

  1. Wiping the file on a towel between clients
  2. Rinsing metal tools in warm water only
  3. Replacing single-use files and disposable items for each client Correct answer.
  4. Spraying the work surface with water after each client

Explanation

Single-use items such as nail files and buffers cannot be reliably disinfected and must be discarded between clients, which removes the physical vehicle for transferring microorganisms. Reusable tools require cleaning followed by an approved disinfectant, not simply water. This is a core principle of infection control in the salon.

Question 22Health, safety, and hygiene in the salon

What is the correct first step when a beauty specialist cleans a reusable metal implement after use?

  1. Wipe it with a dry paper towel and return it to the trolley
  2. Soak it in disinfectant before removing visible debris
  3. Clean it with soap and water to remove debris before disinfection Correct answer.
  4. Store it in a closed drawer and clean it later

Explanation

Organic matter such as skin cells, oils, and product residue can shield microorganisms and reduce disinfectant efficacy, so cleaning must precede disinfection. Disinfecting a visibly soiled tool is ineffective. The standard sequence is clean, rinse, dry, then disinfect.

Question 23Health, safety, and hygiene in the salon

A client arrives with an inflamed, weeping lesion on the scalp before a hair service. What is the most appropriate action for the beauty specialist?

  1. Refer the client to a medical practitioner and decline the service Correct answer.
  2. Cover the lesion with a plaster and continue the service
  3. Apply an antiseptic cream and continue the service
  4. Proceed with the service but wear two pairs of gloves

Explanation

Weeping or inflamed lesions may indicate a contagious or undiagnosed condition, and salon services can worsen it or spread infection. The specialist should not diagnose or treat and should refer the client for medical advice, declining the service until cleared. Gloves or dressings do not make the service safe.

Question 24Health, safety, and hygiene in the salon

Which action demonstrates correct hand hygiene immediately before beginning a client's treatment?

  1. Washing with soap and water, then drying with a single-use towel Correct answer.
  2. Rinsing hands briefly in cold water
  3. Using an alcohol hand rub on visibly soiled hands
  4. Wearing gloves without washing hands first

Explanation

Soap and water physically remove soil and microorganisms, and single-use towels prevent recontamination during drying. Alcohol rubs are less effective when hands are visibly soiled. Gloves are not a substitute for hand hygiene.

Question 25Health, safety, and hygiene in the salon

Which statement correctly describes the difference between disinfection and sterilisation in a salon setting?

  1. Disinfection destroys all microbial life including bacterial spores
  2. Sterilisation reduces microorganisms to a safe level on surfaces
  3. Both terms mean the same process and can be used interchangeably
  4. Disinfection reduces pathogens on inanimate objects, while sterilisation destroys all microorganisms Correct answer.

Explanation

Disinfection reduces or destroys many pathogens on surfaces and tools but may not eliminate spores, whereas sterilisation destroys all microorganisms including spores. Salons generally disinfect tools rather than sterilise them. Using the terms interchangeably is incorrect.

Question 26Health, safety, and hygiene in the salon

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

  1. Discard it and prepare a fresh solution following the manufacturer's instructions Correct answer.
  2. Top it up with fresh concentrate without measuring
  3. Use it as normal because dilution does not affect potency
  4. Add water to restore the original volume

Explanation

Diluted disinfectants lose efficacy over time and when exposed to air, light, or contamination. Manufacturer instructions specify dilution ratios and use-by times, which must be followed. Guessing or topping up compromises concentration and safety.

Question 27Health, safety, and hygiene in the salon

Which of the following best describes the purpose of a Material Safety Data Sheet (SDS) for a salon product?

  1. It lists hazards, safe handling, and first-aid measures for the product Correct answer.
  2. It provides instructions for marketing the product to clients
  3. It records the number of clients treated each month
  4. It guarantees the product is free from allergens

Explanation

A Safety Data Sheet supplies information on hazards, safe handling, storage, and emergency first aid for hazardous substances. It supports risk assessment and safe working practices. It does not certify allergen-free status or serve administrative or marketing purposes.

Question 28Health, safety, and hygiene in the salon

A beauty specialist develops redness and itching on the hands after repeated use of a particular product. Which action is most appropriate?

  1. Apply a stronger perfume to mask the irritation
  2. Share the product with colleagues to finish the stock
  3. Stop using the product, report the reaction, and seek medical advice Correct answer.
  4. Continue using the product but rinse hands less often

Explanation

Skin reactions may indicate contact dermatitis or sensitisation, and continued exposure can worsen the condition. The specialist should stop using the product, report it through the workplace process, and obtain medical advice. Covering up symptoms does not address the cause.

Question 29Health, safety, and hygiene in the salon

How does correct client positioning and posture of the beauty specialist help prevent work-related injury?

  1. It increases the speed of treatments so breaks can be longer
  2. It guarantees the specialist will never experience discomfort
  3. It reduces sustained awkward postures and repetitive strain on the body Correct answer.
  4. It removes the need for adjustable furniture

Explanation

Adjusting the client's position and the specialist's posture reduces prolonged awkward positions and repetitive strain, which are common causes of musculoskeletal disorders. Adjustable furniture and breaks remain important. No posture guarantees the absence of discomfort.

Question 30Health, safety, and hygiene in the salon

Which is the correct way to store clean towels and linen in a salon?

  1. In a closed, clean cupboard separate from soiled linen Correct answer.
  2. In an open basket beside the washbasin
  3. Mixed with used towels to save space
  4. On the floor under the treatment couch

Explanation

Clean linen must be stored in a clean, closed area away from soiled items to prevent contamination. Open storage near a basin or floor exposes linen to splashes, moisture, and dirt. Separating clean and soiled linen is a basic hygiene control.

Question 31Health, safety, and hygiene in the salon

What is the primary reason for wearing gloves when applying a chemical exfoliant or strong cosmetic product?

  1. To protect the specialist's skin from irritation and sensitisation Correct answer.
  2. To improve the absorption of the product
  3. To keep the specialist's hands soft
  4. To reduce the amount of product needed

Explanation

Gloves form a barrier between the specialist's skin and potentially irritating or sensitising chemicals, reducing the risk of contact dermatitis. They are a personal protective measure, not a cosmetic or product-efficiency tool. Barrier protection is a key element of chemical safety.

Question 32Health, safety, and hygiene in the salon

A salon uses a UV nail lamp. Which practice best minimises risk to both client and specialist?

  1. Using the lamp without any cleaning between clients
  2. Increasing exposure time beyond the manufacturer's recommendation
  3. Allowing clients to place hands anywhere on the lamp housing
  4. Following the manufacturer's use instructions and cleaning surfaces between clients Correct answer.

Explanation

Manufacturer instructions define safe exposure and maintenance, and cleaning contact surfaces between clients limits cross-contamination. Extending exposure or allowing uncontrolled contact increases risk. Equipment should be used as designed and kept hygienic.

Question 33Health, safety, and hygiene in the salon

Which of the following is the most reliable indicator that a salon's infection control procedures are being followed?

  1. Clients complimenting the salon's appearance
  2. A large stock of cleaning products
  3. Consistent records of cleaning, disinfection, and staff training Correct answer.
  4. A signed poster on the wall

Explanation

Documented cleaning schedules, disinfection logs, and training records provide evidence that procedures are actually carried out and can be reviewed or audited. Posters and stock levels show intent but not practice. Records support accountability and continuous improvement.

Question 34Health, safety, and hygiene in the salon

What is the safest way to dispose of used single-use blades and sharp implements in a salon?

  1. Flush them down the sink with water
  2. Leave them on the trolley for later collection
  3. Place them in a designated sharps container that is closed and labelled Correct answer.
  4. Wrap them in tissue and place them in the general waste bin

Explanation

Sharps must go into a rigid, closable, labelled sharps container to prevent needlestick injuries and contamination. General waste and sinks are unsafe disposal routes. Prompt disposal also keeps the work area safe.

Question 35Health, safety, and hygiene in the salon

A client reports dizziness and nausea during a facial treatment. Which response is most appropriate?

  1. Continue the treatment and offer a glass of water afterwards
  2. Stop the treatment, ensure the client is safe, and follow the salon's emergency procedure Correct answer.
  3. Ask the client to sign a consent form and continue
  4. Open a window and carry on with the service

Explanation

Sudden dizziness and nausea require stopping the service and assessing the client's safety, following the salon's emergency procedure. Continuing treatment risks worsening the client's condition. A consent form does not address an acute health event.

Question 36Health, safety, and hygiene in the salon

Why should a patch test be carried out before a tinting or chemical service when the product instructions require it?

  1. To test whether the product has expired
  2. To reduce the cost of the treatment
  3. To confirm the client's preferred colour
  4. To identify a potential allergic reaction before a full application Correct answer.

Explanation

A patch test checks for sensitisation or allergic reaction in a small area before full exposure, reducing the risk of a severe reaction. It does not determine colour choice, cost, or expiry. Following product instructions on patch testing is a professional and legal obligation.

Question 37Health, safety, and hygiene in the salon

Which situation requires the beauty specialist to avoid treatment and refer the client elsewhere?

  1. A client who has recently applied sunscreen
  2. A client with a minor cold sore requesting a lip area service
  3. A client with dry skin requesting a moisturising treatment
  4. A client with an active, undiagnosed skin infection in the treatment area Correct answer.

Explanation

An active, undiagnosed skin infection in the treatment area is a contraindication because the service could spread infection or worsen the condition. Dry skin and recent sunscreen are not contraindications. A cold sore near the treatment area also requires care and possible postponement.

Question 38Health, safety, and hygiene in the salon

What is the correct action if a beauty specialist notices a cracked and damaged electrical plug on a treatment device?

  1. Tape the plug and continue using the device
  2. Remove the device from use, label it, and report it for repair Correct answer.
  3. Use the device only on low settings
  4. Ask the client to hold the plug in place

Explanation

Damaged electrical equipment presents a shock and fire risk and must be taken out of service, labelled, and repaired by a competent person. Taping or reducing settings does not remove the hazard. Client involvement is unsafe.

Question 39Health, safety, and hygiene in the salon

A salon offers a treatment involving a strong chemical. Which combination of controls best reflects a hierarchy-of-control approach?

  1. Rely solely on gloves and a verbal reminder to be careful
  2. Use the least hazardous product available, provide local exhaust ventilation, and use appropriate gloves Correct answer.
  3. Post a warning sign and allow staff to decide on protection
  4. Increase the treatment time so less product is used

Explanation

The hierarchy of control prefers eliminating or substituting hazards first, then engineering controls such as ventilation, then personal protective equipment. Combining substitution, ventilation, and gloves addresses risk at multiple levels. Relying on PPE or signs alone is weaker.

Question 40Health, safety, and hygiene in the salon

Which practice supports safe manual handling when moving a heavy portable treatment couch?

  1. Carrying the couch alone to avoid disturbing colleagues
  2. Twisting the torso while lifting to save time
  3. Lifting with straight legs and a bent back
  4. Bending the knees, keeping the load close, and asking for help if needed Correct answer.

Explanation

Bending the knees, keeping the load close to the body, and using assistance reduce strain on the spine and muscles. Twisting and bending the back increase injury risk. Team lifting is appropriate for heavy or awkward loads.

Question 41Anatomy and physiology of the skin and body systems

Which layer of the epidermis is the deepest, where keratinocytes divide by mitosis to renew the skin?

  1. Stratum basale Correct answer.
  2. Stratum corneum
  3. Stratum lucidum
  4. Stratum granulosum

Explanation

The stratum basale (germinativum) sits directly on the basement membrane and contains the actively dividing keratinocytes and melanocytes, so it is the regenerative layer of the epidermis. Cells migrate upward and are eventually shed from the surface.

Question 42Anatomy and physiology of the skin and body systems

Which cell type in the epidermis produces melanin and transfers it to neighbouring keratinocytes?

  1. Fibroblasts
  2. Melanocytes Correct answer.
  3. Merkel cells
  4. Langerhans cells

Explanation

Melanocytes reside in the stratum basale and synthesise melanin in melanosomes, which are transferred to keratinocytes to protect the nucleus from UV damage. This gives the skin its pigment and contributes to photoprotection.

Question 43Anatomy and physiology of the skin and body systems

Which structure in the dermis is responsible for the skin's elasticity and recoil?

  1. Collagen fibres
  2. Ground substance
  3. Reticular fibres
  4. Elastin fibres Correct answer.

Explanation

Elastin fibres form a network that allows the skin to stretch and return to its original shape, providing recoil. Collagen provides tensile strength rather than elasticity.

Question 44Anatomy and physiology of the skin and body systems

Sebum is produced by which glands and has which primary role?

  1. Sebaceous glands; lubricating skin and hair and helping to waterproof the surface Correct answer.
  2. Apocrine glands; producing scent in the axillae
  3. Eccrine glands; cooling the body by sweating
  4. Ceruminous glands; producing earwax

Explanation

Sebaceous glands secrete sebum, an oily substance that lubricates the skin and hair and contributes to the acid mantle and waterproofing. They are usually associated with hair follicles.

Question 45Anatomy and physiology of the skin and body systems

Which function of the skin describes its role in regulating body temperature through sweating and blood vessel changes?

  1. Protection
  2. Sensation
  3. Thermoregulation Correct answer.
  4. Excretion

Explanation

Thermoregulation is the skin's ability to control heat loss through sweating and vasodilation or vasoconstriction of dermal blood vessels. This keeps core temperature stable.

Question 46Anatomy and physiology of the skin and body systems

Which vitamin is synthesised in the skin when it is exposed to ultraviolet light?

  1. Vitamin K
  2. Vitamin A
  3. Vitamin C
  4. Vitamin D Correct answer.

Explanation

UVB light converts 7-dehydrocholesterol in the epidermis into vitamin D3, which is then activated by the liver and kidneys. This is a key function of the skin beyond barrier protection.

Question 47Anatomy and physiology of the skin and body systems

Which of the following is the correct order of the layers of the skin from outermost to innermost?

  1. Epidermis, dermis, subcutaneous layer Correct answer.
  2. Subcutaneous layer, dermis, epidermis
  3. Dermis, epidermis, subcutaneous layer
  4. Epidermis, subcutaneous layer, dermis

Explanation

The skin consists of the outer epidermis, the underlying dermis and the subcutaneous (hypodermis) layer beneath. This order reflects the structural arrangement from the surface inwards.

Question 48Anatomy and physiology of the skin and body systems

Which sensory receptor in the skin detects light touch and is located close to the skin surface?

  1. Free nerve ending
  2. Ruffini ending
  3. Meissner corpuscle Correct answer.
  4. Pacinian corpuscle

Explanation

Meissner corpuscles are located in the dermal papillae near the surface and detect light touch and low-frequency vibration. Pacinian corpuscles lie deeper and detect pressure and vibration.

Question 49Anatomy and physiology of the skin and body systems

A client has a wound that has broken through the epidermis and into the dermis. Which term best describes this depth of wound?

  1. Deep partial-thickness Correct answer.
  2. Superficial partial-thickness
  3. Epidermal only
  4. Full-thickness

Explanation

A deep partial-thickness wound extends into the dermis while some dermal tissue remains, which affects healing and scarring. Superficial partial-thickness involves only the upper epidermis.

Question 50Anatomy and physiology of the skin and body systems

Which change in the skin is most directly caused by ageing and reduced collagen production?

  1. Increased sebum production
  2. Thickening of the stratum corneum
  3. Increased melanocyte activity
  4. Thinning of the dermis and reduced elasticity Correct answer.

Explanation

Ageing reduces collagen and elastin synthesis, so the dermis thins and loses elasticity, leading to wrinkles and sagging. Sebum production typically decreases rather than increases.
