BRPT Infection Control and Safety Protocols 1 — Questions and Answers
Question 1: Which level of disinfection is required for reusable PAP masks and headgear between patients?
- Sterilization
- High-level disinfection (Correct answer)
- Intermediate-level disinfection
- Low-level disinfection
Correct answer: High-level disinfection
Reusable PAP masks and headgear are semi-critical items that contact mucous membranes and require high-level disinfection between patients.
Question 2: According to Standard Precautions, which body fluid does NOT always require PPE protection?
- Blood
- Semen
- Sweat (Correct answer)
- Cerebrospinal fluid
Correct answer: Sweat
Standard Precautions do not require PPE for sweat because sweat is not considered an infectious body fluid.
Question 3: What is the CDC-recommended duration for routine hand hygiene with soap and water?
- 5–10 seconds
- 15–20 seconds
- At least 20 seconds (Correct answer)
- At least 60 seconds
Correct answer: At least 20 seconds
The CDC recommends scrubbing hands with soap and water for at least 20 seconds to effectively reduce pathogens.
Question 4: Which disinfectant concentration of sodium hypochlorite (bleach) is appropriate for cleaning blood spills on environmental surfaces?
- 1:10 dilution (approximately 5,000 ppm) (Correct answer)
- 1:100 dilution (approximately 500 ppm)
- 1:1,000 dilution (approximately 50 ppm)
- Undiluted bleach only
Correct answer: 1:10 dilution (approximately 5,000 ppm)
A 1:10 dilution of bleach (approximately 5,000 ppm available chlorine) is required for blood spills to ensure effective disinfection.
Question 5: Under OSHA's Bloodborne Pathogen Standard, employers must offer the hepatitis B vaccine series at no cost to which employees?
- All hospital employees
- Only laboratory workers
- Employees with occupational exposure to blood or OPIM (Correct answer)
- Employees who request it regardless of exposure risk
Correct answer: Employees with occupational exposure to blood or OPIM
OSHA requires employers to offer hepatitis B vaccination at no cost to all employees who have occupational exposure to blood or other potentially infectious materials (OPIM).
Question 6: Which type of isolation precautions would be most appropriate for a patient with active pulmonary tuberculosis undergoing a sleep study?
- Contact precautions
- Droplet precautions
- Airborne precautions (Correct answer)
- Standard precautions only
Correct answer: Airborne precautions
Pulmonary TB is transmitted via airborne droplet nuclei (<5 µm), requiring airborne precautions including an N95 respirator and negative-pressure room.
Question 7: Used sharps should be placed in which type of container immediately after use?
- A sealed plastic bag
- A puncture-resistant sharps container (Correct answer)
- A labeled cardboard box
- A standard biohazard bag
Correct answer: A puncture-resistant sharps container
OSHA requires immediate disposal of used sharps into a puncture-resistant, leak-proof sharps container to prevent needlestick injuries.
