2. A worker has just finished an injection. What is the safest routine action for the used needle?
Recap it with two hands before carrying it away
Place it immediately in a nearby approved sharps container
Set it on a tray until all procedures are complete

4. A sharps container has reached its marked fill line. What should happen next?
Push the contents down while wearing puncture-resistant gloves
Transfer some sharps into a second container
Continue using it until the opening becomes blocked

5. A small blood spill is found on a work surface. After restricting access and putting on appropriate protection, what is the best cleanup approach?
Use the approved spill procedure and disinfectant for the required contact time
Rinse the surface with water so the blood becomes diluted
Wipe it with a dry paper towel and discard the towel in ordinary trash
Leave the spill to dry fully before sweeping the residue away
6. A task may cause blood to splash toward a worker's face and clothing. Which protection is most appropriate?
Gloves plus suitable eye or face protection and a protective gown or garment

A cloth face covering without eye protection or protective clothing
A protective gown alone because splashes mainly affect clothing

Inspect the gloves and skip hand hygiene if no tear is found
Perform hand hygiene only if blood was visible on the gloves
Put on a fresh pair before touching the sink or sanitizer
Perform hand hygiene promptly, even if the gloves appeared intact
8. For which major occupational bloodborne infection is a preventive vaccine widely available?
Hepatitis B
Hepatitis C
HIV
No major bloodborne infection has a preventive vaccine
9. Immediately after a needlestick, what should the affected worker do first?
Squeeze the wound forcefully until it bleeds
Cover the site and wait to see whether symptoms appear

Apply a strong disinfectant directly inside the puncture
10. Which event represents a potential bloodborne-pathogen exposure?
Touching a clean supply cabinet with bare hands
Speaking with an injured person from several feet away
Walking past a closed sharps container
Receiving a splash of blood in the eye
11. What is the main purpose of a workplace exposure control plan?
To provide a list of workers who have previously been ill
To replace task-specific training with one written document
To describe how exposure hazards are identified, prevented, and managed
To determine whether an exposed worker has acquired an infection
12. Why should a possible occupational blood exposure be reported promptly?
Because symptoms reliably appear within the first few hours
Because timely evaluation, documentation, testing, and preventive care may be important
Because reporting eliminates the need to wash or flush the exposed area
Because immediate reporting proves that transmission occurred
13. A blood-contaminated glass tube breaks on the floor. What is the best way to collect the pieces?

14. Which statement best reflects standard precautions when handling human blood?
Precautions are needed only when a person is known to have an infection
Precautions can be skipped when the amount of blood is very small
Precautions apply only in hospitals and clinical laboratories
Human blood should be handled as potentially infectious regardless of known status
15. Which situation is least likely to provide a route for a bloodborne pathogen to enter the body?
A contaminated sharp punctures the skin
Blood contacts an unprotected eye
Blood briefly touches healthy, intact skin and is promptly washed off
Blood enters an uncovered cut on a hand
16. A towel is visibly contaminated with blood. How should it be handled for laundering or disposal?
