6.4 The Blood Exposure Procedure Segment
Key Takeaways
- In Nevada's blood exposure segment the injury is to the candidate — a minor cut on the back of your own hand — and you must identify where the cut is before you begin.
- The graded sequence is: stop the service, retrieve the first aid kit without contaminating clean supplies, glove the non-injured hand, apply pressure, clean and cover the wound, bag contaminated materials, change gloves as needed, and disinfect the station.
- The glove goes on the NON-injured hand, because that is the hand doing the work on the wound.
- Contaminated materials go into the labeled biohazard bag, matching NAC 644A.705(4) for disposable material contaminated with blood or bodily fluids.
- NAC 644A.780 bars a licensee from performing any service on skin that is inflamed, infected, broken, or otherwise compromised, or on a client whose skin secretes bodily fluids.
What the Board Asks For
Quick Answer: "You have sustained a minor cut on the back of your hand. Please identify where the cut is on your hand before you begin. Demonstrate proper infection prevention procedures for blood exposure. Immediately stop the service, retrieve your first aid kit, and remove necessary items without contaminating clean supplies. Put on a clean glove on your non-injured hand. Apply pressure to control bleeding, then clean and properly cover the wound. Dispose of all contaminated materials into a labeled biohazard bag, change gloves as needed, and clean and disinfect your workstation while maintaining proper infection control practices throughout the procedure."
Two features of Nevada's version surprise candidates trained elsewhere:
- The injury is yours, not a client's. Most state practicals script a nick to the model. Nevada scripts a minor cut on the back of your own hand — and there is no live model on the Nevada nail practical anyway, only a mannequin hand.
- You must point to the cut first. "Please identify where the cut is on your hand before you begin." Skipping that identification means the examiner cannot follow which hand is injured and which hand you are gloving.
The Graded Sequence
The examiner grades the order, not just whether the steps eventually happen.
| Step | Action | Why it is in this position |
|---|---|---|
| 1 | Identify the cut on the back of your hand | The examiner must know which hand is contaminated |
| 2 | Immediately stop the service | Nothing else is safe while a service is in progress over an open wound |
| 3 | Retrieve the first aid kit and remove only the items you need, without contaminating clean supplies | The moment of highest cross-contamination risk — do not paw through the clean kit with a bleeding hand |
| 4 | Put on a clean glove on your NON-injured hand | The uninjured hand is the working hand; it must be barriered before it touches blood |
| 5 | Apply pressure to control bleeding | Bleeding stops before anything is cleaned or covered |
| 6 | Clean the wound | Cleaning precedes covering; sealing contaminants under a bandage is a classic fail |
| 7 | Properly cover the wound with a bandage | Barrier the wound before returning to any surface |
| 8 | Dispose of all contaminated materials into the labeled biohazard bag | Contaminated waste never touches the trash bag or the station |
| 9 | Change gloves as needed | Gloves that handled blood do not then handle clean disinfectant wipes |
| 10 | Clean and disinfect the workstation | Return the station to a serviceable state |
Step 4 is the one candidates most often reverse. Ask yourself which hand will hold the gauze, the antiseptic wipe, and the bandage — that is the non-injured hand, and that is the hand that gets the glove.
Why the Biohazard Bag Is a Separate, Labeled Bag
The supply list calls for one sandwich-size plastic bag labeled "biohazard waste," separate from the three paper bags for Trash, Soiled Linen, and Items to be disinfected. That is not exam theater — it mirrors NAC 644A.705:
- NAC 644A.705(4): any disposable material that comes into contact with blood or other bodily fluids must be disposed of in a sealable plastic bag or in a manner that protects the licensee, the client, and anyone who may later contact the material, such as sanitation workers.
- NAC 644A.705(5): to prevent the spread of any bloodborne disease or virus, disposable sharp objects that contact blood or bodily fluids must go into a sealable rigid container strong enough to prevent accidental cuts or punctures — and regardless of exposure to blood, disposable sharp objects including blades, needles, and lancets must be disposed of in labeled sharps containers.
So the gauze, the used antiseptic wipe, and the contaminated gloves go into the labeled biohazard bag; a sharp goes into a rigid sharps container. Putting bloodied cotton in the ordinary Trash bag is a graded error and a live regulatory violation.
The Regulation Behind "Stop the Service"
NAC 644A.780 makes stopping mandatory rather than discretionary:
- "A licensee shall not perform any service upon a surface of the skin or scalp of a client where such skin is inflamed, infected, broken or otherwise compromised."
- "Licensees shall not perform any service on a client whose skin shows signs of secretion of any bodily fluids."
NAC 644A.865 classifies a violation of NAC 644A.775 through 644A.790 as gross malpractice, which under NRS 644A.850 exposes the licensee to Board discipline. The practical segment is a rehearsal for a rule with real teeth.
NAC 644A.775 governs the mirror-image situation — when you are the infection risk. A person afflicted with an infectious or communicable disease that may be transmitted during the practice of cosmetology, or with an infestation of animal parasites, shall not work or train in an establishment or school. Section 2.7 lists the named conditions and their return-to-work timings.
Errors That Fail the Segment
- Continuing the service. The single most serious error. The instruction says immediately stop.
- Gloving the injured hand instead of the non-injured hand, or working bare-handed.
- Contaminating clean supplies while retrieving first aid items — reaching into the closed kit with a contaminated hand, or setting bloodied gauze on the clean station.
- Covering before cleaning. A bandage over an uncleaned wound traps contaminants.
- Wrong receptacle. Contaminated material in the Trash or Soiled Linen bag instead of the labeled biohazard bag.
- Not changing gloves before handling clean disinfectant wipes and the station.
- Skipping the final disinfection of the workstation, or forgetting to sanitize your hands after glove removal.
- Talking. Talking is prohibited throughout the practical and is an automatic failure — demonstrate the procedure, do not narrate it.
Practice It Until It Is Muscle Memory
Set up a station, place the biohazard bag where you can reach it without crossing clean supplies, and run the sequence cold ten times: identify, stop, retrieve without contaminating, glove the non-injured hand, pressure, clean, cover, bag, change gloves, disinfect, sanitize hands, step back. Time it. Under exam pressure the sequence is what survives, and the sequence is exactly what is graded.
In the Nevada blood exposure segment, on which hand do you put the clean glove?
A candidate controls the bleeding, then places the blood-soaked gauze in the paper bag labeled 'Trash' before disinfecting the station. What is wrong?
