Biohazard And Needle-Stick Exposure Response - NCLEX-PN

Blood and certain body fluids; treat as potentially infectious. Under Standard Precautions, these fluids may contain bloodborne pathogens like HIV, HBV, or HCV, requiring universal handling as infectious.

Saliva (unless visibly bloody). Saliva has low HIV concentration unless contaminated with blood, unlike blood which is highly infectious for bloodborne pathogens.

Wash the area promptly with soap and water. This initial cleansing minimizes pathogen transmission by removing contaminants from the puncture site without causing further tissue damage.

Replace sharps containers when near full. Replacing containers at 3/4 full prevents overfilling, which can cause sharps to protrude and increase injury risk during disposal.

Standard Precautions. Standard Precautions apply universally to prevent bloodborne pathogen transmission, unlike airborne for respiratory droplet diseases.

Remove gloves first, then perform hand hygiene. Removing gloves first prevents transfer of contaminants to hands, with hygiene then eliminating any residual microbes.

Don PPE; clean then disinfect with an approved agent. PPE protects during cleanup, and sequential cleaning followed by disinfection eliminates viable pathogens from environmental surfaces.

Use risk-reduction precautions until cleared by follow-up testing. Precautions like barrier protection and avoiding blood donation prevent secondary transmission during the window period before test confirmation.

Start HIV PEP promptly per protocol and obtain source testing. For confirmed HIV sources, immediate PEP reduces transmission risk, with source testing providing details on viral load and resistance.

Percutaneous blood exposure. Percutaneous exposures involve higher inoculum and direct vascular access, meeting criteria for PEP evaluation per CDC guidelines.

As soon as possible, ideally within hours. Early initiation maximizes PEP efficacy in preventing HIV seroconversion, with effectiveness decreasing significantly after 72 hours.

Hepatitis B vaccination and antibody response status. Assessing HBV immunity determines need for vaccine booster or HBIG, as it's a preventable bloodborne pathogen with high occupational risk.

Determine pre-exposure infection status for follow-up comparison. Baseline serology establishes the exposed person's status for HIV, HBV, and HCV, enabling detection of seroconversion in subsequent tests.

Time, route, device, fluid, source info, and actions taken. Comprehensive documentation supports risk assessment, legal compliance, and guides follow-up care for potential bloodborne infections.

Percutaneous injury. Percutaneous routes breach skin barriers, allowing direct bloodstream access for pathogens, unlike intact skin which resists penetration.

Hollow-bore blood-filled needle. Hollow-bore needles can transfer larger blood volumes directly into tissues, elevating transmission risk for pathogens like HIV or HBV.

Do not recap; if unavoidable, use one-hand scoop technique. Recapping increases needlestick risk; the scoop method minimizes hand exposure if recapping is absolutely necessary.

Place directly into a puncture-resistant sharps container. Immediate disposal in designated containers prevents accidental injuries and complies with OSHA regulations for safe sharps handling.

Gloves (and additional PPE as indicated by splash risk). Gloves provide a barrier against direct contact, with added PPE preventing splashes to mucous membranes or non-intact skin.

Standard Precautions. This CDC-recommended approach assumes all such materials could transmit bloodborne pathogens, promoting consistent infection control practices.

Irrigate eyes with water or saline immediately. Immediate irrigation flushes out potentially infectious material from mucous membranes to reduce the risk of bloodborne pathogen absorption.

Rinse mouth thoroughly with water; spit out. Rinsing dilutes and removes infectious fluids from oral mucous membranes, which are permeable and at risk for pathogen transmission.

Wash skin with soap and water. Washing removes surface contaminants, as intact skin provides a barrier but may have micro-abrasions allowing potential entry.

Report the exposure immediately per facility protocol. Prompt reporting ensures timely medical evaluation, source testing, and potential post-exposure prophylaxis to mitigate infection risks.
