4.4 Bloodborne Pathogens & Sharps/Exposure
Key Takeaways
- Bloodborne pathogens such as hepatitis B, hepatitis C, and HIV spread when blood or certain body fluids contact non-intact skin, mucous membranes, or a sharp.
- Under the OSHA Bloodborne Pathogens Standard, the CNA treats all blood and body fluids as infectious and wears gloves whenever contact is possible.
- Sharps, razors, and broken glass are never picked up by hand; they go directly into a labeled, puncture-resistant sharps container, which is never overfilled.
- After a blood or body-fluid exposure, wash or flush the area, report to the nurse immediately, and follow the facility exposure-control plan.
- Biohazard-labeled bags and containers hold blood-soaked or infectious waste and are never mixed with regular trash; soiled linen is bagged where used and never shaken.
Bloodborne Pathogens
Bloodborne pathogens are infectious organisms carried in blood and certain body fluids. The three most important in healthcare are:
- Hepatitis B virus (HBV) — a liver infection; the most contagious of the three and the one with a vaccine.
- Hepatitis C virus (HCV) — a liver infection spread mainly through blood; no vaccine.
- Human immunodeficiency virus (HIV) — attacks the immune system and can lead to AIDS; no vaccine.
They spread when infected blood or fluid contacts non-intact skin (cuts, rashes, abrasions), the eyes, nose, or mouth (mucous membranes), or enters through a needle or sharp. They are not spread by casual contact such as hugging, sharing a meal table, or touching intact skin.
The OSHA Bloodborne Pathogens Standard
The Occupational Safety and Health Administration (OSHA) Bloodborne Pathogens Standard is the federal rule behind standard precautions. Its core principle: treat all blood and body fluids as potentially infectious regardless of the resident's diagnosis. The CNA never needs to know whether a resident carries HBV, HCV, or HIV — the protection is the same for everyone. The standard also requires the employer to provide PPE, an exposure-control plan, training, and the hepatitis B vaccination series at no cost to employees with exposure risk.
How The CNA Stays Protected
- Wear gloves whenever contact with blood or body fluids is possible.
- Add a gown, mask, and eye protection when splashing or spraying is possible.
- Cover your own cuts or open skin with a bandage before giving care.
- Accept the hepatitis B vaccine offered to healthcare workers.
- Never eat, drink, or apply makeup in care areas.
Safe Sharps Handling
A CNA's routine duties do not include needles, but a CNA may encounter a used sharp, a razor, or broken glass. The rules:
| Situation | Correct Action |
|---|---|
| Used sharp or needle found | Do not pick it up by hand and never recap it; tell the nurse and use the sharps container per policy |
| Sharps container | Puncture-resistant, leak-proof, labeled with the biohazard symbol; never overfill (replace at the fill line) and never reach inside |
| Broken glass | Use a brush and dustpan or tongs, never bare hands |
| Disposable razor | Discard in the sharps container after shaving care |
Exposure Response
If blood or body fluid contacts your skin, eyes, nose, or mouth, or you sustain a sharps injury, act immediately — do not wait until the end of the shift:
- Care for the exposure site first. Wash a needlestick or skin exposure with soap and water; flush eyes, nose, or mouth with large amounts of water or saline.
- Report to the nurse or supervisor right away.
- Follow the facility exposure-control plan, including incident documentation and any required medical evaluation and follow-up testing or treatment.
Prompt reporting matters because post-exposure treatment for HBV or HIV is most effective when started quickly.
Biohazard Waste And Linen
Biohazard-labeled bags and containers hold blood-soaked dressings, heavily contaminated items, and other infectious waste — these are never placed in regular trash. Soiled linen is handled carefully:
- Bag it where it is used; do not carry loose soiled linen down the hall.
- Never shake linen — shaking sends germs into the air.
- Hold it away from your uniform, roll the dirtiest surface inward, and place it in the designated hamper or bag.
- Wear gloves, and perform hand hygiene after handling.
Following the facility waste plan protects residents, staff, and the housekeeping and laundry workers who handle the waste downstream.
Hepatitis B Vaccine And The Employee's Rights
Because HBV is the most contagious of the three main bloodborne pathogens and a vaccine exists, OSHA requires the employer to offer the hepatitis B vaccine series free of charge to employees with occupational exposure risk, usually within the first weeks of hire. A worker who declines must sign a declination form but can change their mind and receive the vaccine later at no cost. The series gives long-lasting protection and is the single most effective bloodborne-pathogen safeguard a CNA can accept.
Engineering And Work-Practice Controls
OSHA expects the facility to reduce exposure through more than PPE alone:
- Engineering controls are physical safeguards: sharps containers, safer needle devices, leak-proof biohazard bags, and handwashing sinks.
- Work-practice controls are safer habits: not recapping needles, not eating in care areas, performing hand hygiene, and disposing of waste correctly.
- PPE is the last layer when the first two cannot fully remove the hazard.
Common Exam Traps
| Trap | Correct Thinking |
|---|---|
| "The resident has no known infection, so no gloves are needed" | Standard precautions apply to everyone; glove for expected fluid contact |
| "Recap the needle to make it safe" | Never recap; recapping causes many needlesticks |
| "Report the exposure at the end of the shift" | Report immediately so post-exposure care can start |
| "Put the blood-soaked dressing in the regular trash" | Use the biohazard-labeled container |
| "Shake the linen to remove debris first" | Never shake; it aerosolizes germs |
Putting It Together
Bloodborne-pathogen safety is simply standard precautions applied to blood and sharps: assume everything is infectious, glove and protect the face when splashing is possible, never handle sharps by hand, report exposures at once, and route contaminated waste and linen through the biohazard system. A CNA who follows these habits every time protects both residents and themselves and answers nearly every exposure-control question correctly.
