Handle Hazardous Materials Safely - ARRT Radiography Exam
- What is the correct hand hygiene method when hands are visibly soiled after patient contact?
- Wash with soap and water. Soap and water effectively remove visible soil and pathogens, adhering to CDC guidelines for hand hygiene when alcohol-based sanitizers are insufficient.
- What is the correct first action when a chemical spill occurs in the imaging area?
- Ensure personal safety and isolate the area. Prioritizing personal safety and area isolation prevents immediate harm and limits spill spread before initiating cleanup or notification protocols.
- What is the minimum immediate first aid for chemical splash to the eye in the department?
- Irrigate at eyewash station continuously. Continuous irrigation dilutes and removes the chemical, minimizing ocular damage as per OSHA and facility emergency response guidelines.
- Which option is correct for storing chemicals in the imaging department to reduce hazards?
- Store in original containers with labels; segregate incompatibles. Original labeled containers and segregation prevent accidental mixing or reactions, complying with OSHA storage requirements to enhance safety.
- What is the correct PPE sequence for donning before entering an isolation room?
- Gown, mask/respirator, goggles/face shield, gloves. This donning sequence minimizes contamination risks by covering the body progressively, aligning with infection control protocols in isolation settings.
- Which isolation category requires an N95 respirator for suspected airborne infectious disease?
- Airborne precautions. Airborne precautions protect against pathogens transmitted via respiratory droplets, requiring fitted N95 respirators to filter airborne particles effectively.
- Which SDS section lists required PPE and exposure controls for a chemical used in radiography?
- Section 8: Exposure Controls/Personal Protection. This section specifies engineering controls, administrative measures, and PPE to minimize exposure risks when using chemicals in radiographic procedures.
- Which container is required for disposal of used needles or scalpel blades in radiography?
- Puncture-resistant sharps container. Sharps containers prevent accidental punctures and contain biohazardous sharps, complying with OSHA regulations for safe disposal in medical imaging.
- What is the correct first step in PPE doffing to reduce self-contamination in most cases?
- Remove gloves first. Removing gloves first prevents transfer of contaminants from highly soiled items to cleaner PPE or skin during the doffing process.
- Find the error: You recap a used needle after injection. What is the correct action?
- Do not recap; dispose immediately in a sharps container. Avoiding recapping reduces needlestick risks, with immediate sharps disposal ensuring safe handling per OSHA bloodborne pathogens standard.
- Identify the correct cleaning approach for imaging equipment visibly contaminated with blood.
- Wear PPE and disinfect with an EPA-registered hospital disinfectant. PPE protects the cleaner, while EPA-registered disinfectants ensure effective pathogen elimination on contaminated surfaces per infection control standards.
- What is the required labeling standard for secondary chemical containers in clinical areas?
- Product identifier and hazard warnings (GHS/OSHA compliant). GHS/OSHA standards mandate clear labeling on secondary containers to communicate hazards and ensure safe handling in clinical environments.
- Which action best prevents cross-contamination when transporting a patient on contact precautions?
- Perform hand hygiene and disinfect equipment after transport. Hand hygiene and disinfection after transport break the chain of infection, preventing pathogen spread from patients under contact precautions.
- Identify the correct action after a needlestick injury from a used needle in radiography.
- Wash/flush, report immediately, and follow exposure protocol. Immediate washing, reporting, and protocol adherence facilitate prompt medical evaluation and reduce risks of bloodborne pathogen transmission.
- Which fire extinguisher class is appropriate for ordinary combustibles such as paper and cloth?
- Class A. Class A extinguishers are designed for water-based suppression of fires involving common solids, ensuring effective response in non-electrical scenarios.
- What is the correct disposal container for blood-soaked gauze from a procedure room?
- Red biohazard waste bag/container. Red biohazard containers are designated for infectious waste to segregate and safely manage materials contaminated with blood or bodily fluids.
- What is the safest immediate response to a mercury spill from a broken thermometer?
- Isolate area and follow hazardous materials spill protocol. Isolating the area prevents exposure to toxic mercury vapors, allowing specialized cleanup per hazardous materials protocols to minimize health risks.
- Which symbol indicates a biohazard and requires special handling of contaminated materials?
- Biohazard symbol. The universal biohazard symbol alerts personnel to potential infectious risks, mandating precautions like PPE and proper disposal to prevent transmission.
- Which acronym outlines the correct response sequence when discovering a fire in the facility?
- RACE: Rescue, Alarm, Contain, Extinguish/Evacuate. RACE prioritizes life safety and containment, providing a systematic approach to fire emergencies in healthcare facilities as per NFPA standards.
- Identify the correct action: You find an unlabeled spray bottle in the control room.
- Do not use; label properly or dispose per facility policy. Unlabeled containers pose unknown hazards, so non-use and proper labeling or disposal prevent accidents per hazard communication regulations.
- What does SDS stand for in chemical hazard communication within the imaging department?
- Safety Data Sheet. SDS is the standardized document under OSHA's Hazard Communication Standard that details chemical properties, risks, and safe handling practices in medical settings.
- What is the correct action if a sharps container is filled to the indicated fill line?
- Close and replace the container immediately. Replacing full sharps containers prevents overfilling, reducing risks of needlestick injuries and ensuring compliance with safety standards.
- Which acronym describes how to operate a fire extinguisher during a small, controllable fire?
- PASS: Pull, Aim, Squeeze, Sweep. PASS ensures safe and effective extinguisher use by guiding users through activation and application to control small fires without escalating risks.
