Blood-borne Pathogens
Key Points
- Blood-borne pathogens are infectious microorganisms in blood and body fluids that can cause disease.
- The source highlights key examples: hepatitis-b, hepatitis-c, and hiv.
- Sharps injuries and skin breaks are major occupational exposure routes in healthcare work.
- OSHA Blood-borne Pathogens Standard defines required prevention and postexposure processes.
- Immediate wash or flush plus rapid supervisor notification is required after exposure.
Pathophysiology
blood-borne-pathogens are transmitted when infected blood or body fluid reaches a vulnerable portal-of-entry, such as broken skin or mucous membranes. In healthcare settings, risk increases during tasks involving sharps, blood handling, and cleanup of contaminated fluids.
The source identifies needlesticks and sharps injuries as key exposure mechanisms. It also identifies shaving-related cuts and razor disposal as relevant nursing-assistant risk points. This supports strict sharps-safety practices and use of puncture-resistant disposal systems.
From a systems perspective, prevention and response are regulated by occupational safety standards. OSHA Blood-borne Pathogens Standard requires training, exposure response workflows, and postexposure assessment. Rapid escalation reduces delay in medical evaluation and follow-up.
Classification
- Pathogen examples: hepatitis-b, hepatitis-c, and hiv.
- Exposure mechanisms: Needlestick injuries, contaminated sharps, and blood contact through nonintact skin.
- High-risk care tasks: Shaving with skin-break potential, blood spill cleanup, and sharps handling.
- Regulatory control layer: OSHA prevention and postexposure requirements.
Nursing Assessment
NCLEX Focus
Questions often test immediate priority after exposure and correct PPE selection during blood spill events.
- Identify whether blood or body-fluid contact reached nonintact skin or mucous membranes.
- Determine if sharps were involved and whether disposal followed facility protocol.
- Assess task context, including shaving, cleanup workflow, and PPE use.
- Verify immediate decontamination actions were completed without delay.
- Report and document exposure details for required postexposure-assessment.
Nursing Interventions
- Use personal-protective-equipment appropriate to blood or fluid exposure risk.
- Wear gloves during shaving and manage razors as potential sharps.
- Dispose of razors, needles, and broken glass in approved sharps containers.
- For blood spills, apply face shield, gown, and gloves before cleanup.
- After exposure, wash or flush affected area immediately and notify nurse supervisor.
- Follow agency policy for urgent postexposure evaluation and required follow-up.
Delay In Postexposure Evaluation
Waiting to report or evaluate exposure can delay time-sensitive clinical decisions and increase safety risk.

Clinical Judgment Application
Clinical Scenario
During resident shaving, a disposable razor causes a small skin break, and the assistant later notices blood on an unprotected hand abrasion.
Recognize Cues: Blood contact, nonintact skin exposure, and sharps-related task. Analyze Cues: Occupational blood-borne pathogen exposure is possible. Prioritize Hypotheses: Immediate decontamination and reporting are higher priority than routine documentation. Generate Solutions: Wash or flush exposure site, notify supervisor, and initiate policy-based postexposure workflow. Take Action: Perform immediate cleansing, report at once, and complete required exposure documentation. Evaluate Outcomes: Timely postexposure assessment completed and no additional unprotected exposure events.
