NIC Esthetics theory exam: 10 free practice questions

Ten real questions from our NIC Esthetics bank, with the keyed answer and an explanation for each. The NIC National written examination for estheticians is the paper most states use. No signup, nothing to install.

1. Scientific Concepts

   1. A blood-spill on a treatment-room surface should be cleaned by

   1. spraying with alcohol and air drying.
   2. waiting until the end of the day to address it, once the last client has left the treatment room.
   3. gloving, absorbing and cleaning it, then applying an EPA-registered bloodborne-pathogen disinfectant.
   4. wiping with a dry paper towel and discarding it.

   Answer: gloving, absorbing and cleaning it, then applying an EPA-registered bloodborne-pathogen disinfectant.

   Bloodborne pathogen spill protocol requires PPE, containment and absorption of the spill, cleaning, and disinfection with a product effective against bloodborne pathogens; contaminated waste is placed in a labeled biohazard container.

2. Scientific Concepts

   2. Bacteria that are spherical in shape and grow in clusters resembling a bunch of grapes are

   1. staphylococci.
   2. streptococci, which grow in chains or rows.
   3. spirilla, the spiral or corkscrew forms.
   4. diplococci which grow in pairs.

   Answer: staphylococci.

   Staphylococci are round (cocci) bacteria that grow in irregular grape-like clusters and are commonly associated with abscesses and skin infections. Streptococci grow in chains. Diplococci grow in pairs. Spirilla are spiral-shaped, not round.

3. Scientific Concepts

   3. The general term for one-celled microorganisms that exhibit both plant and animal characteristics is

   1. parasites.
   2. viruses.
   3. bacteria.
   4. fungi.

   Answer: bacteria.

   Bacteria are one-celled prokaryotes; standard esthetics textbooks (Milady) classify them under protista — the CIB-testable convention. (Modern taxonomy: Domain Bacteria, not Kingdom Protista.)

4. Scientific Concepts

   4. The mechanism by which AHAs exfoliate the skin is

   1. chemical breakdown of the alkaline bonds, which hold the living cells together within the deeper layers of the epidermis.
   2. loosening of the bonds between corneocytes at the base of the stratum corneum, facilitating desquamation.
   3. physical abrasion of the stratum corneum by the acid's granular particles.
   4. enzymatic digestion of the keratin protein within the corneocyte.

   Answer: loosening of the bonds between corneocytes at the base of the stratum corneum, facilitating desquamation.

   AHAs exfoliate by disrupting the ionic bonds and weakening the desmosomal attachments between corneocytes, facilitating natural shedding. They are chemical, not physical, exfoliants and contain no granules. Enzymatic exfoliants digest keratin protein.

5. Scientific Concepts

   5. Rod-shaped bacteria that can produce protective spores allowing them to survive harsh conditions are classified as

   1. protozoa, the single-celled animals.
   2. bacilli.
   3. spirilla.
   4. cocci, the round bacteria.

   Answer: bacilli.

   Bacilli are rod-shaped bacteria, and certain species can form endospores that resist heat, drying, and many disinfectants. Cocci are round. Spirilla are spiral or corkscrew shaped. Protozoa are single-celled animals, not bacteria.

6. Esthetics Procedures

   6. When a client declines to answer health questions on the intake form, the esthetician should

   1. ask a co-worker to persuade the client to complete the form, before proceeding.
   2. proceed with the service and assume no health issues exist.
   3. refuse to provide any services at all until every section of the form is completed in full.
   4. explain why it is needed, document the refusal, and take a conservative approach.

   Answer: explain why it is needed, document the refusal, and take a conservative approach.

   Clients have the right to decline health disclosures, but this limits contraindication screening. The professional response is to explain the purpose, document the refusal, and deliver the most conservative service possible.

7. Esthetics Procedures

   7. A client intake form used before a skin care service should include

   1. a detailed record of the esthetician's own product preferences and preferred treatment protocol.
   2. a printed menu of the salon's available service upgrades, along with their retail prices.
   3. the client's social security and credit card numbers.
   4. health history, current medications, known allergies, and skin care concerns.

   Answer: health history, current medications, known allergies, and skin care concerns.

   The intake form is a clinical screening tool. Health history, medications, allergies, and skin concerns guide the treatment plan and identify contraindications. Financial and marketing information is not the purpose.

8. Esthetics Procedures

   8. The purpose of a client consultation before a skin care service is to

   1. record the client's preferences, for later use in the salon's marketing.
   2. assess the client's ability to pay for premium services and upgrades.
   3. identify and sell the client the complete range of full-size retail products that best match their skin type and stated budget.
   4. gather information about the client's skin, health history, and goals to determine safe and appropriate services.

   Answer: gather information about the client's skin, health history, and goals to determine safe and appropriate services.

   The consultation establishes the clinical foundation — identifying contraindications, skin type, conditions, medications, and client goals. Retail, financial, and marketing purposes are secondary.

9. Esthetics Procedures

   9. During a skin analysis, the esthetician uses a magnifying lamp primarily to

   1. warm the skin surface, to open the pores before cleansing.
   2. measure the skin's pH before selecting a cleanser.
   3. examine the skin closely for texture, lesions, pore size, hydration, and pigmentation.
   4. shine ultraviolet light on the skin to reveal bacterial colonies and hidden pigmentation deep within the dermis.

   Answer: examine the skin closely for texture, lesions, pore size, hydration, and pigmentation.

   The magnifying lamp provides illumination and magnification for thorough visual analysis — texture, comedones, lesions, Hyperpigmentation, dehydration lines, and pore size. It does not generate heat, identify bacteria, or measure pH.

10. Esthetics Procedures

    10. A client's intake form reveals she is in her first trimester of pregnancy. The esthetician should

    1. review pregnancy contraindications, get physician clearance, and modify the service.
    2. recommend aggressive peels to treat the Hyperpigmentation that pregnancy tends to cause.
    3. proceed with the usual service, since pregnancy has little effect on skin treatment safety.
    4. turn the client away and ask her to rebook her facials for after the baby is born.

    Answer: review pregnancy contraindications, get physician clearance, and modify the service.

    Pregnancy requires service modification — contraindicated treatments include deep peels, certain essential oils, high-frequency, and strong heat. Physician clearance is recommended particularly in the first trimester.
