  1. HAIs account for an estimated?
    2 million infections
  2. Approximately how many patients under mechanical ventilation develop pneumonia as a complication?
  3. Approximately how many patients will die as a result of lung infection?
  4. What is the PRIMARY source for infectious agents in a health care setting?
    Humans (patients, personnel, or visitors)
  5. When a pathogen is transferred directly from one person to another, this transmission is called?
    Direct contact transmission
  6. This is the most frequent mode of transmission in the health care environment which involves the transfer of pathogens through a contaminated intermediate object or person..
    Indirect contact transmission
  7. This form of transmission is generated by an infected individual that discharges large contaminated liquid droplets into the air by coughing, sneezing or talking
    Droplet transmission
  8. HICPAC states that we should wear a mask and stand how far away from the patient who is on droplet isolation..?
  9. NIOSH approved of what mask to be prevent airborne transmission...?
  10. What is chemoprophylaxis?
    the use of a drug or chemical to prevent a disease
  11. OSHA requires employers offer what?
    Hepatitis B vaccination
  12. Infection control procedures designed to remove environmental pathogens fall into two major categories which are?
    General sanitation measures

    Specialized equipment processing
  13. Equipment processing involves what three things?
    • Cleaning
    • Disinfection
    • Sterilization
  14. The three major approaches used to prevent the spread of infection in healthcare agencies are?
    • Specialized equipment handling procedures
    • Barrier/isolation precautions
    • Single-patient-use disposable equipment
  15. What is the first step in all equipment processing?
  16. Electrical equipment should be disinfected using a ________ solution or the equivalent.
    70% ethyl alcohol

    Steam sterilization which is the application of steam under pressure.
  20. Which is the worse offender of nebulizers?
    Large volume nebulizers
  21. Ventilator circuitry poses the most significant contamination risk, particularly in systems using heated humidifier because?
    tapwater or distilled water may harbor heat-resistant pathogens, thus sterile water should be used.

    • Contact
    • Droplet
    • Airborne infection
    • Protective environment
  23. What is cohorting?

  24. What are the five key recommended components of an infection control program?
    • investigation
    • prevention
    • control
    • reporting
    • surveillance
