Om denne test
Det her er en gratis smagsprøve på 15 spørgsmål til den skriftlige del af en amerikansk cosmetology-prøve, skrevet af StudyPDF-teamet. Cosmetology er den amerikanske autorisation til arbejde med hår, hud og negle. Smagsprøven dækker den teori, som alle delstatsprøver tester: infektionshygiejne og sikkerhed, kemien i hårprodukter, hårets, hudens og neglenes opbygning og principperne bag behandlinger af hår, hud og negle. Den blander multiple choice, vælg alle der passer og udfyld det tomme felt. Svar på alle 15 spørgsmål, se så din score og læs forklaringen til hvert spørgsmål.

1.Which level of infection control destroys all microbial life, including bacterial spores?
- A. Cleaning
- B. Disinfection
- C. Sterilization
- D. Antisepsis
Svar: C. Sterilization
Cleaning removes dirt, debris and some germs. Disinfection with an EPA-registered product destroys most pathogens on hard, nonporous surfaces, but it is not guaranteed to destroy bacterial spores. Sterilization destroys every form of microbial life, spores included, and it takes equipment such as an autoclave. Antisepsis means slowing or stopping germs on skin, so it is not a level for tools. Salon tools are normally cleaned and then disinfected, so check what your board requires for each type of tool.
2.Hair is held at 90 degrees from the curve of the head and cut to the same length all over. What does this produce?
- A. A solid, one-length form
- B. A graduated form with stacked weight
- C. Increased-length layers
- D. Uniform layers
Svar: D. Uniform layers
The angle the hair is held at (the elevation) decides the form. Hair held at 0 degrees gives a solid, one-length shape, and low elevation of about 45 degrees builds a graduated shape with weight at the perimeter. At 90 degrees every section is cut to the same length, which gives uniform layers. Above 90 degrees the layers lengthen toward the outside, which is an increased-length layer.
3.A razor nicks a client's skin during a service and it begins to bleed. After stopping the service, what should the professional do?
- A. Wipe the blood away with a towel and continue the service
- B. Put on gloves, stop the bleeding, clean the cut with an antiseptic and cover it
- C. Rinse the tool under water and finish the service
- D. Ask the client to press a tissue on the cut while the service continues
Svar: B. Put on gloves, stop the bleeding, clean the cut with an antiseptic and cover it
Bleeding is a blood exposure, so the service stops. Put on gloves, control the bleeding, clean the injury with an antiseptic and cover it with a bandage. Anything that touched the blood is then either thrown away if it is single-use, or cleaned and disinfected with a product that is effective against blood-borne pathogens before it is used again. Contaminated waste goes into a closed container. Your state board publishes its own blood exposure procedure, so learn that version.
4.Product A has a pH of 4.5 and product B has a pH of 6.5. How do they compare?
- A. A is 100 times as acidic as B
- B. A is 10 times as acidic as B
- C. A is 2 times as acidic as B
- D. A is 1,000 times as acidic as B
Svar: A. A is 100 times as acidic as B
The pH scale is logarithmic, so each whole number is a tenfold change in acidity. Two units apart is 10 x 10 = 100 times. A pH of 7 is neutral, anything below it is acidic and anything above it is alkaline. Hair and skin are slightly acidic, which is why acidic products tend to smooth the cuticle and strongly alkaline ones swell and lift it.
5.Which layer of the hair shaft holds most of the natural pigment and gives the hair its strength and elasticity?
- A. Cuticle
- B. Medulla
- C. Cortex
- D. Follicle
Svar: C. Cortex
The cortex is the thick middle layer. It holds the melanin that gives hair its color and the protein bonds that give it strength and stretch, which is why color, perms and relaxers all do their work there. The cuticle is the outer layer of overlapping scales that protects the inside. The medulla is the innermost core and is often missing in fine hair. The follicle is the pocket in the skin that the hair grows from, so it is not a layer of the shaft.
6.A client's hair was lightened and now looks brassy orange. Which tone on the color wheel will best cancel the orange?
- A. Blue-based
- B. Red-based
- C. Yellow-based
- D. Orange-based
Svar: A. Blue-based
Colors opposite each other on the color wheel cancel each other out. Blue sits opposite orange, so a blue-based or ash toner neutralizes brassy orange. Violet cancels yellow and green cancels red. Adding red, yellow or orange would only make the warmth stronger.
7.Before a first-time permanent hair color service, the stylist does a skin test (also called a predisposition test). What is it checking for?
- A. How porous the client's hair is
- B. Whether the client is allergic or sensitive to the product
- C. How many levels of lift the color will give
- D. Whether the scalp makes too much oil
Svar: B. Whether the client is allergic or sensitive to the product
A skin test checks for an allergic reaction or sensitivity. A small amount of the product is applied to a spot such as behind the ear or inside the elbow, usually 24 to 48 hours before the service. Itching, redness, swelling or a rash means the color is not used. A strand test is the different test: it shows how the hair will take the color and how long it needs. Follow the manufacturer's directions and your state's rules for how and when to test.
8.Which structure in the skin produces sebum?
- A. Sudoriferous gland
- B. Arrector pili
- C. Papilla
- D. Sebaceous gland
Svar: D. Sebaceous gland
Sebaceous glands are attached to hair follicles and release sebum, the skin's natural oil. Sudoriferous glands make sweat. The arrector pili is the tiny muscle that makes a hair stand up, and the papilla is the cluster of tissue at the base of the follicle that feeds the growing hair.
9.Which part of the nail unit makes new nail cells, so that damage to it can cause lasting growth problems?
- A. Nail bed
- B. Matrix
- C. Hyponychium
- D. Eponychium
Svar: B. Matrix
The matrix lies under the skin at the base of the nail, and it is where new nail cells are made. If it is injured, the nail can grow in distorted or not at all. The nail bed supports and feeds the plate, the hyponychium is the skin that seals the space under the free edge, and the eponychium is the living skin at the base of the nail plate, commonly called the cuticle.
10.Which of these are porous and cannot be properly disinfected, so they are thrown away or given to the client after one use?
Vælg alle, der passer.
- A. Wooden orangewood stick
- B. Stainless steel cuticle nippers
- C. Foam nail buffer block
- D. Plastic comb
- E. Cardboard emery board
Svar: A. Wooden orangewood stick, C. Foam nail buffer block, E. Cardboard emery board
Wood, foam and cardboard are porous, so germs and moisture soak in where a disinfectant cannot reach them. These items are single-use. Stainless steel and hard plastic are nonporous, so after cleaning they can be disinfected for the next client. Some boards let you hand the used item to the client instead of throwing it away, so check your own board's rule.
11.In which situations should a professional decline the service and suggest the client see a physician?
Vælg alle, der passer.
- A. Mild dandruff with no broken skin
- B. Open, weeping sores on the scalp
- C. Slightly dry skin on the elbows
- D. A thickened, yellow nail that crumbles at the edge and may be a fungal infection
- E. Live head lice found on the scalp
Svar: B. Open, weeping sores on the scalp, D. A thickened, yellow nail that crumbles at the edge and may be a fungal infection, E. Live head lice found on the scalp
Open sores, a suspected fungal nail infection and head lice are contagious or infected conditions. Working on them can spread the problem to the client and to the next client, and diagnosing is outside a cosmetologist's scope, so the safe step is to decline and refer. Mild dandruff and dry skin are common and not contagious, so the service can usually go ahead, often with a suggestion for a suitable product.
12.Which statements about the bonds in the hair are correct?
Vælg alle, der passer.
- A. Hydrogen bonds break with water or heat and re-form as the hair dries or cools
- B. Disulfide bonds are changed by perms and relaxers, so the new shape lasts
- C. Disulfide bonds break every time the hair gets wet
- D. Hydrogen bonds are the strongest bonds in the hair
Svar: A. Hydrogen bonds break with water or heat and re-form as the hair dries or cools, B. Disulfide bonds are changed by perms and relaxers, so the new shape lasts
Hydrogen bonds are weak and temporary. Water or heat breaks them and they set again in the new shape as the hair dries or cools, which is how wet setting and thermal styling work. Disulfide bonds are much stronger and only chemical services change them, which is why a perm or relaxer is long lasting. Getting hair wet does not break disulfide bonds.
13.Complete the sentence.
Healthy skin and hair are slightly acidic, with a pH of about _____. A product with a pH well above 7 is _____ and can swell and roughen the cuticle.
Muligheder for felt 1: 2.0 to 3.0, 4.5 to 5.5, 7.0 to 8.0, 10.0 to 11.0
Muligheder for felt 2: acidic, neutral, alkaline, oily
Svar: 4.5 to 5.5, alkaline
Skin and hair sit at roughly pH 4.5 to 5.5, the slightly acidic range. A pH above 7 is alkaline. Alkaline products swell the hair shaft and lift the cuticle, which is useful in some chemical services and rough on hair when it is overdone. Acidic products tend to close and smooth the cuticle.
14.Complete the sentence.
A salon disinfectant must be _____ registered, and it only works if the surface stays wet for the full _____ printed on the label.
Muligheder for felt 1: FDA, OSHA, EPA, USDA
Muligheder for felt 2: shelf life, contact time, drying time, expiration date
Svar: EPA, contact time
In the United States the EPA registers disinfectants, so the label carries an EPA registration number. OSHA sets workplace safety rules, such as safety data sheets and blood exposure rules, but it does not register disinfectants. The contact time is how long the product must stay wet on the surface to kill what the label claims, and wiping it off sooner than that cuts the effect.
15.Complete the sentence.
New skin cells form in the _____ of the epidermis and slowly move upward until they are shed from the _____.
Muligheder for felt 1: basal layer, stratum corneum, dermis, subcutis
Muligheder for felt 2: stratum corneum, basal layer, dermis, hypodermis
Svar: basal layer, stratum corneum
The epidermis renews itself from the bottom. Cells divide in the basal layer, the deepest layer of the epidermis, and gradually move toward the surface as they flatten and harden. The outermost layer is the stratum corneum, and the dead cells that reach it are shed. The dermis and the subcutis lie below the epidermis, so they are not part of it.
Hvad den skriftlige cosmetology-prøve dækker, og hvad den ikke dækker
Hver delstats board udsteder sin egen cosmetology-licens. Det betyder, at den skriftlige prøve, beståelsesgrænsen, antallet af uddannelsestimer og om en praktisk prøve er en del af forløbet, alt sammen afhænger af, hvor du søger. En udbredt skriftlig prøve er NIC-teoriprøven, bygget af National-Interstate Council of State Boards of Cosmetology og afviklet af et prøvefirma som PSI. Nogle boards bruger en anden prøve eller en anden leverandør. Før du stoler på et tal, du har set online, så åbn din delstats kandidathåndbog og læs indholdsoversigten, formatet og beståelsesgrænsen for din delstat.
NIC-teoriens håndbog beskriver 110 spørgsmål på 90 minutter, hvoraf 100 tæller. Oversigten grupperer indholdet i fire områder: naturvidenskabelige begreber (infektionshygiejne og sikkerhed, hårets, hudens og neglenes anatomi og fysiologi samt produkternes grundlæggende kemi), hårpleje og behandlinger, hudpleje og behandlinger samt neglepleje og behandlinger. Én offentliggjort version vægter dem 30, 40, 15 og 15 procent, og andre versioner afviger en smule, hvilket er endnu en grund til at læse den aktuelle håndbog for dit board. Hårbehandlinger er den største blok, men det er i naturvidenskabsblokken, mange mister point, fordi den spørger, hvorfor et trin udføres, og ikke kun hvad trinnet er.
Den praktiske prøve er noget andet. Hvor et board kræver en, tester den håndværk på en øvedukke eller en model under tidspres, og en tekstside kan ikke træne det. Denne prøve dækker kun den skriftlige teori. Supplér med praktiske øvelser på din skole, og spørg din underviser, hvordan dit boards praktiske prøve ser ud.
Sådan bruger du smagsprøven
De 15 spørgsmål er spredt over hele oversigten: infektionshygiejne og sikkerhed, produktkemi og pH, hårets, hudens og neglenes opbygning og ræsonnementet bag behandlinger af hår, hud og negle. De fleste tester principper, der gælder i alle delstater, for eksempel hvorfor et redskab rengøres, før det desinficeres, eller hvorfor en hudtest kommer før en farvebehandling. Hvor loven eller produktets etiket fastsætter reglen, vinder din delstat og producentens anvisninger over alt på denne side.
Tag den i ét stræk uden noter. Bruger din prøve NIC-formatet, giver 110 spørgsmål på 90 minutter cirka 49 sekunder per spørgsmål, så sigt efter omkring halvandet minut på opgaverne af typen vælg alle der passer og mindre på resten. Læs så forklaringen til hvert spørgsmål, også dem du svarede rigtigt på, for et heldigt gæt ser ud som rigtig viden på en scoreskærm.
Behandl hver fejl som et emne. Hvis du missede pH-spørgsmålet og spørgsmålet om desinfektionsmidler, er problemet ikke to fakta, men kemiblokken. Gå tilbage til din lærebog for den blok, og vend så tilbage til smagsprøven. Spørgsmålene er originale, skrevet af StudyPDF-teamet efter de offentliggjorte indholdsområder, og ingen af dem stammer fra en autorisationsprøve eller et forlags spørgsmålsbank.
Sådan bygger StudyPDF cosmetology-øveprøver ud fra dine egne noter
Femten spørgsmål kan vise dig, hvilken blok der vakler. De kan ikke gøre dig klar alene, og den prøve, du skal op til, bygger på din delstats regler og den lærebog, din skole bruger, ikke på en generisk bank.
StudyPDF arbejder ud fra dit eget materiale i stedet. Upload kapitler fra din cosmetology-lærebog, din undervisers slides eller noter eller din delstats kandidathåndbog, tryk på Nyt materiale, og StudyPDF bygger øveprøver ud fra præcis de sider. Hvert spørgsmål bygger på dit materiale, og hver forklaring henviser til, hvor svaret kommer fra, så du kan gå direkte tilbage til siden, når et trin ikke giver mening.
Du behøver ikke uploade noget for at komme i gang. Nævn i stedet et emne, for eksempel kemisk glatning (chemical relaxers) eller niveauer af infektionshygiejne, så sætter Bo det op med dets nøglebegreber, og du kan bygge quizzer og flashcards ud fra det. Dine resultater følger, hvilke begreber du bliver ved med at misse, så den næste øveprøve kan målrettes dem. Det er gratis at starte.

Godt at vide
Er denne cosmetology-øveprøve gratis, og hvor kommer spørgsmålene fra?
Ja. Alle 15 spørgsmål, scoreskærmen og hver eneste forklaring er gratis at spille i din browser. StudyPDF-teamet har skrevet hvert spørgsmål og hver forklaring ud fra de offentliggjorte indholdsområder i cosmetology-teori. Det er originale opgaver, ikke rigtige eksamensspørgsmål, og StudyPDF er ikke tilknyttet NIC, PSI, noget lærebogsforlag eller noget delstats cosmetology-board.
Hvor mange spørgsmål er den rigtige skriftlige prøve, og hvilken score består?
NIC-teoriprøvens håndbog beskriver 110 spørgsmål på 90 minutter, hvoraf 100 tæller. Ikke alle delstater bruger den prøve, og hvert delstats board fastsætter sin egen beståelsesgrænse og sine egne uddannelsestimer, så der findes ikke ét nationalt tal. Læs dit boards kandidathåndbog for det format og den score, der gælder, hvor du søger.
Dækker den den praktiske prøve?
Nej. Den praktiske prøve, hvor dit board kræver en, tester håndværk på en øvedukke eller en model under tidspres, og en tekstside kan ikke træne det. Denne smagsprøve dækker kun den skriftlige teori, så brug din skoles praktiske øvelser ved siden af og spørg din underviser, hvad dit board forventer.
Kan jeg få øveprøver bygget ud fra min egen lærebog og mine noter?
Ja. Upload dine lærebogskapitler, din undervisers slides eller din delstats kandidathåndbog til StudyPDF, så kan du bygge øveprøver ud fra præcis de sider, med forklaringer knyttet til dine kilder. Har du ikke noget at uploade, så nævn et emne, for eksempel kemisk glatning eller infektionshygiejne, i stedet.
