How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which step is required if a safety-engineered needle has a safety feature after use?

Answer: Activate the safety device immediately after use. Activating the safety mechanism shields the needle, reducing the risk of accidental sticks during handling or disposal.

Flashcard 2: What action is contraindicated after a needle-stick exposure due to tissue damage risk?

Answer: Do not squeeze, milk, or scrub the puncture site. Such actions can cause further tissue trauma and drive pathogens deeper into the wound, increasing infection likelihood.

Flashcard 3: What baseline laboratory test is indicated for the exposed worker after a significant exposure?

Answer: Baseline HIV test (and HBV/HCV serologies as indicated). Baseline testing establishes the worker's pre-exposure status for monitoring seroconversion and guiding treatment.

Flashcard 4: Which device-related factor increases bloodborne pathogen transmission risk in a needle-stick?

Answer: Hollow-bore needle with visible blood. Hollow-bore needles can contain and inject larger volumes of blood, heightening pathogen transmission potential.

Flashcard 5: What key information about the exposure should be documented as part of the initial report?

Answer: Time, device, fluid, route, depth, and PPE used. Detailed documentation aids in risk assessment, guiding appropriate post-exposure prophylaxis and follow-up care.

Flashcard 6: Which body fluid is treated as potentially infectious for bloodborne pathogens in standard precautions?

Answer: Blood (and any fluid visibly contaminated with blood). Blood is the primary vehicle for transmitting pathogens like HIV, HBV, and HCV under universal precautions.

Flashcard 7: Identify the correct action after a used needle injury: recap for transport or dispose immediately in sharps?

Answer: Dispose immediately in an approved sharps container. Immediate disposal in a sharps container minimizes handling risks and prevents recapping-related injuries.

Flashcard 8: What baseline evaluation is needed for hepatitis B management after exposure?

Answer: Determine exposed worker hepatitis B vaccination and anti-HBs status. Assessing vaccination and antibody levels determines immunity and the need for post-exposure interventions like HBIG.

Flashcard 9: Which response is appropriate after a needle-stick: delay reporting until end of shift or report immediately?

Answer: Report immediately per facility protocol. Immediate reporting facilitates timely risk assessment and prophylaxis, which are critical for effective exposure management.

Flashcard 10: Which action is correct when blood splashes into the eye: apply disinfectant or irrigate with saline?

Answer: Irrigate with saline or water immediately. Irrigation safely flushes contaminants from the eye without causing chemical irritation that disinfectants might induce.

Flashcard 11: Which needle practice is prohibited to reduce needle-stick injuries?

Answer: Recapping used needles by hand. Recapping increases the risk of accidental needle-sticks due to mishandling of contaminated sharps.

Flashcard 12: Which exposure is significant for HBV/HCV: blood on chapped skin or blood on intact skin?

Answer: Blood on chapped (non-intact) skin. Non-intact skin provides a portal for HBV/HCV entry, unlike intact skin which acts as a barrier to transmission.

Flashcard 13: Which immediate action is required after a needle-stick injury in a clinical setting?

Answer: Wash the site with soap and water immediately. Prompt cleansing removes potential contaminants from the wound to minimize infection risk before further medical evaluation.

Flashcard 14: What is the correct disposal method for a used needle immediately after use?

Answer: Place directly into a puncture-resistant sharps container. Sharps containers prevent accidental injuries and contain biohazards safely, complying with infection control standards.

Flashcard 15: Identify the exposure type that is considered a true bloodborne pathogen exposure.

Answer: Percutaneous injury or mucous membrane contact with blood. These routes allow direct entry of bloodborne pathogens into the bloodstream or tissues, posing significant transmission risk.

Flashcard 16: What is the correct immediate response after blood contacts the mouth?

Answer: Rinse mouth with water repeatedly; spit out. Repeated rinsing helps expel contaminants from the oral cavity, preventing ingestion or absorption of bloodborne pathogens.

Flashcard 17: What is the correct initial step if a sharps container is overfilled: push contents down or replace container?

Answer: Replace the container; do not push contents down. Replacing the container avoids the hazard of forcing sharps down, which could lead to needle-stick injuries.

Flashcard 18: What is the correct immediate response after blood contacts intact skin?

Answer: Wash thoroughly with soap and water. Soap and water effectively cleanse the skin surface, removing potential infectious material without damaging intact barriers.

Flashcard 19: What is the general timing goal for initiating HIV PEP after an occupational exposure?

Answer: Initiate immediately, ideally within hours of exposure. Rapid initiation maximizes PEP efficacy in preventing HIV infection by targeting the virus during its early replication phase.

Flashcard 20: Which intervention is most time-sensitive after suspected HIV exposure at work?

Answer: Start HIV post-exposure prophylaxis (PEP) as soon as possible. Early PEP initiation interrupts HIV replication, significantly reducing the risk of seroconversion after exposure.

Flashcard 21: Which statement best describes HIV PEP duration for occupational exposure when indicated?

Answer: A 28-day course of antiretroviral therapy. The 28-day regimen provides sufficient antiretroviral coverage to prevent establishment of HIV infection post-exposure.

Flashcard 22: Which exposure requires HIV PEP consideration: needle-stick with blood or urine splash to intact skin?

Answer: Needle-stick with blood. Blood via needle-stick poses a direct percutaneous risk for HIV transmission, unlike urine on intact skin which does not.

Flashcard 23: Which action is required immediately after first aid for a needle-stick exposure at work?

Answer: Report the exposure immediately per facility protocol. Timely reporting ensures prompt medical evaluation, testing, and potential prophylaxis to mitigate infection risks.

Flashcard 24: Which patient factor most increases transmission risk after a percutaneous exposure to blood?

Answer: Known positive HIV, HBV, or HCV status of the source. A source with confirmed infection elevates the probability of pathogen transmission through the exposure event.

Flashcard 25: What is the correct immediate response after a blood splash to the eyes?

Answer: Irrigate eyes with water or saline immediately. Immediate irrigation dilutes and removes infectious material from sensitive mucous membranes to reduce absorption of pathogens.
