Asepsis & Infection Control Quiz

Asepsis & Infection Control

Environmental Sanitation

• Definition: The process of maintaining a clean and safe environment to reduce the risk of infections.
• Key Practices:
  • Regular cleaning and disinfection of surfaces and equipment.
  • Proper waste disposal to minimize contamination.
  • Control of pests and vermin to reduce vectors of disease.
• Air Quality: Ensuring adequate ventilation and air filtration in healthcare settings.

Personal Protective Equipment (PPE)

• Purpose: To protect healthcare workers and patients from exposure to infectious agents.
• Types of PPE:
  • Gloves: For handling contaminated materials.
  • Masks: To prevent inhalation of pathogens.
  • Gowns: To protect skin and clothing from contamination.
  • Face shields or goggles: To protect eyes and face from splashes.
• Usage Guidelines:
  • Proper donning (putting on) and doffing (removing) techniques to prevent self-contamination.
  • Ensure PPE is appropriate for the level of exposure risk.

Hand Hygiene

• Importance: Most effective method to prevent the spread of infections.
• Methods:
  • Handwashing with soap and water: Effective for visible dirt and certain pathogens.
  • Alcohol-based hand sanitizers: Recommended when soap and water are not available.
• When to Perform:
  • Before and after patient contact.
  • Before aseptic procedures.
  • After exposure to bodily fluids or contaminated surfaces.

Sterilization Techniques

• Definition: The process of eliminating all forms of microbial life, including spores.
• Common Methods:
  • Autoclaving: Uses steam under pressure; effective for most instruments.
  • Dry heat sterilization: Used for materials that cannot withstand moisture.
  • Chemical sterilants: For heat-sensitive equipment (e.g., ethylene oxide).
  • Radiation: Used for single-use items and certain surgical instruments.
• Monitoring: Biological indicators to ensure effectiveness of sterilization processes.

Infection Transmission Routes

• Direct Transmission: Immediate transfer of pathogens from person to person (e.g., touching, kissing).
• Indirect Transmission: Involves intermediaries, such as contaminated surfaces or objects (fomites).
• Droplet Transmission: Pathogens spread through respiratory droplets from coughing or sneezing.
• Airborne Transmission: Infectious agents that remain suspended in the air and can be inhaled.
• Vector-borne Transmission: Spread of infections through vectors (e.g., mosquitoes, ticks).

Environmental Sanitation

• Maintaining a clean and safe environment reduces infection risks.
• Regular cleaning and disinfection of surfaces and equipment are crucial.
• Proper waste disposal minimizes contamination, preventing infection spread.
• Pest control is essential to reduce disease vectors.
• Ensuring good air quality through ventilation and filtration improves safety in healthcare.

Personal Protective Equipment (PPE)

• PPE safeguards healthcare workers and patients from infectious agents.
• Types include:
  • Gloves: Protect against contamination while handling materials.
  • Masks: Prevent inhalation of infectious particles.
  • Gowns: Shield skin and clothing from contamination.
  • Face shields/goggles: Protect eyes and face from splashes.
• Proper donning and doffing techniques are critical to avoid self-contamination.
• PPE must match the level of exposure risk to be effective.

Hand Hygiene

• Hand hygiene is the most effective method for preventing infection spread.
• Handwashing with soap and water effectively removes dirt and certain pathogens.
• Alcohol-based hand sanitizers are a practical alternative when soap is unavailable.
• Key moments to perform hand hygiene:
  • Before and after patient interactions.
  • Before performing aseptic procedures.
  • After contact with bodily fluids or contaminated surfaces.

Sterilization Techniques

• Sterilization eliminates all microbial life, including spores.
• Common methods of sterilization include:
  • Autoclaving: Uses steam under pressure, effective for most instruments.
  • Dry heat sterilization: Suitable for materials that are moisture-sensitive.
  • Chemical sterilants: Used for heat-sensitive equipment, such as ethylene oxide.
  • Radiation sterilization: Effective for single-use items and specific surgical instruments.
• Biological indicators are necessary for monitoring the effectiveness of sterilization methods.

Infection Transmission Routes

• Direct Transmission: Pathogens transferred directly between individuals via physical contact.
• Indirect Transmission: Involves contaminated surfaces or objects (fomites) acting as intermediaries.
• Droplet Transmission: Spread through respiratory droplets from coughing or sneezing.
• Airborne Transmission: Infectious agents that remain airborne and can be inhaled.
• Vector-borne Transmission: Infections spread through vectors like mosquitoes and ticks.
