Key Areas Covered in the Skills Module 3.0 Infection Control Posttest

The posttest typically covers a range of essential topics, reflecting the multifaceted nature of infection control. Here's a breakdown of the key areas you can expect to encounter:

1. Modes of Transmission: Understanding how infections spread is the cornerstone of prevention. The posttest will likely assess your knowledge of various transmission routes, including:

   • Contact Transmission:
     • Direct Contact: Physical transfer of microorganisms between an infected person and a susceptible host.
     • Indirect Contact: Transfer via a contaminated intermediate object, such as equipment or surfaces.
   • Droplet Transmission: Spread of large respiratory droplets produced during coughing, sneezing, or talking. These droplets travel short distances (typically less than 6 feet).
   • Airborne Transmission: Dissemination of small particles or droplet nuclei that can remain suspended in the air for extended periods and travel longer distances.
   • Common Vehicle Transmission: Spread through contaminated food, water, medications, or devices.
   • Vectorborne Transmission: Transmission by insects or other animals.

2. Standard Precautions: These are the foundational infection control practices that should be implemented with all patients, regardless of their suspected or confirmed infection status. The posttest will evaluate your understanding of each component of standard precautions:

   • Hand Hygiene: This is the single most important measure to prevent the spread of infection. You should be familiar with the proper techniques for handwashing with soap and water and using alcohol-based hand sanitizers. The posttest might assess:
     • Indications for hand hygiene (e.g., before and after patient contact, after removing gloves, after contact with bodily fluids).
     • Correct handwashing procedure (duration, technique).
     • Appropriate use of alcohol-based hand sanitizers.
   • Personal Protective Equipment (PPE): PPE acts as a barrier between healthcare workers and potentially infectious materials. The posttest will likely cover:
     • Types of PPE (gloves, gowns, masks, eye protection).
     • Proper selection and use of PPE based on the level of risk.
     • Donning and doffing procedures to prevent self-contamination.
   • Respiratory Hygiene/Cough Etiquette: Measures to contain respiratory secretions and prevent their spread. This includes:
     • Covering coughs and sneezes with a tissue or elbow.
     • Providing tissues and hand sanitizer to patients and visitors.
     • Separating individuals with respiratory symptoms.
   • Safe Injection Practices: Preventing transmission of infections through contaminated needles and syringes. This includes:
     • Using a new sterile syringe and needle for each injection.
     • Avoiding recapping needles.
     • Using single-dose vials whenever possible.
   • Safe Handling of Contaminated Equipment and Sharps: Preventing injuries and transmission of infections from contaminated items. This includes:
     • Proper disposal of sharps in designated containers.
     • Decontamination and sterilization of reusable equipment.
     • Safe handling and transport of soiled linens.

3. Transmission-Based Precautions: These are additional infection control measures implemented for patients with known or suspected infections spread through contact, droplet, or airborne routes. The posttest will assess your understanding of each type of transmission-based precaution:

   • Contact Precautions: Used for infections spread through direct or indirect contact. This includes:
     • Private room or cohorting patients with the same infection.
     • Use of gloves and gowns upon entry to the patient's room.
     • Dedicated equipment for the patient.
   • Droplet Precautions: Used for infections spread through large respiratory droplets. This includes:
     • Private room or cohorting patients with the same infection.
     • Use of a mask upon entry to the patient's room.
     • Maintaining a distance of at least 6 feet from other patients and visitors.
   • Airborne Precautions: Used for infections spread through small airborne particles. This includes:
     • Airborne Infection Isolation Room (AIIR) – a negative pressure room that prevents air from flowing out of the room.
     • Use of a respirator (e.g., N95 mask) upon entry to the patient's room.
     • Limiting the movement of the patient outside of the room.

4. Environmental Cleaning and Disinfection: Maintaining a clean and disinfected environment is crucial to prevent the spread of infections. The posttest will likely assess your knowledge of:

   • Appropriate cleaning and disinfection agents.
   • Frequency of cleaning and disinfection for different surfaces and equipment.
   • Proper procedures for cleaning up spills of blood and other bodily fluids.

5. Sterilization and Disinfection: Understanding the differences between sterilization and disinfection, and the appropriate methods for each, is vital. The posttest will likely cover:

   • Sterilization: A process that eliminates all microorganisms, including spores.
   • Disinfection: A process that eliminates most microorganisms, but not necessarily spores.
   • Different methods of sterilization (e.g., autoclaving, chemical sterilization).
   • Different levels of disinfection (high-level, intermediate-level, low-level).
   • Appropriate methods for sterilizing or disinfecting different types of equipment.

6. Healthcare-Associated Infections (HAIs): Understanding the common types of HAIs and strategies for preventing them is a key component. The posttest might include questions about:

   • Common HAIs (e.g., catheter-associated urinary tract infections (CAUTIs), central line-associated bloodstream infections (CLABSIs), surgical site infections (SSIs), ventilator-associated pneumonia (VAP)).
   • Evidence-based strategies for preventing specific HAIs (e.g., proper catheter insertion and maintenance techniques for CAUTI prevention, hand hygiene and aseptic technique for CLABSI prevention).

7. Infection Control Policies and Procedures: Healthcare facilities have specific policies and procedures in place to guide infection control practices. The posttest may assess your familiarity with these policies, including:

   • Reporting procedures for suspected or confirmed infections.
   • Protocols for managing outbreaks of infectious diseases.
   • Employee health policies related to infection control (e.g., vaccination requirements, management of exposures to bloodborne pathogens).

8. Specific Pathogens: While the test won't delve into exhaustive microbiology, understanding the basics of common and significant pathogens is important. This includes:

   • Clostridium difficile (C. difficile): Causes antibiotic-associated diarrhea and colitis. Emphasis on handwashing with soap and water (alcohol-based hand sanitizers are not effective against spores).
   • Methicillin-resistant Staphylococcus aureus (MRSA): A bacterium resistant to many antibiotics.
   • Vancomycin-resistant Enterococcus (VRE): Another bacterium resistant to many antibiotics.
   • Carbapenem-resistant Enterobacteriaceae (CRE): A family of bacteria that are highly resistant to antibiotics.
   • Tuberculosis (TB): An airborne disease that primarily affects the lungs.
   • Influenza: A respiratory illness caused by influenza viruses.
   • Norovirus: A highly contagious virus that causes vomiting and diarrhea.

Common Misconceptions and Pitfalls

Several common misconceptions can hinder effective infection control practices. Being aware of these pitfalls can help you avoid them:

• "If it looks clean, it is clean." Visual cleanliness does not guarantee the absence of microorganisms. Surfaces may be contaminated even if they appear clean.
• "Hand sanitizer is a substitute for handwashing." Alcohol-based hand sanitizers are effective in many situations, but they are not a substitute for handwashing with soap and water when hands are visibly soiled or after caring for patients with certain infections (e.g., C. difficile).
• "PPE is only necessary when caring for patients with known infections." Standard precautions require the use of PPE whenever there is a risk of exposure to blood or other body fluids, regardless of the patient's infection status.
• "One glove fits all." Gloves should be appropriately sized to ensure a proper fit and prevent tearing.
• "It's okay to recap needles if you're careful." Recapping needles is a dangerous practice that can lead to needlestick injuries. Needles should never be recapped.
• "Disinfection is the same as sterilization." Disinfection eliminates most microorganisms, but not necessarily spores. Sterilization eliminates all microorganisms, including spores. The choice between disinfection and sterilization depends on the intended use of the item.
