Match the following precautions with their methods of transmission:

Airborne precautions = Pathogens transmitted through air via moisture or dust particles Droplet precautions = Transmission through coughing, sneezing, talking, etc. by an infected person Contact precautions = Infectious agents spread by direct or indirect contact with the patient or the patient’s environment

Match the following precautions with their requirements for patient room:

Airborne precautions = Private room with monitored negative air pressure Droplet precautions = Private room Contact precautions = Private room if available

Match the following precautions with their requirements for healthcare workers:

Airborne precautions = Wear a respiratory mask (N95) Droplet precautions = Wear a mask Contact precautions = Wear gloves and a gown; wash hands with an antimicrobial or antiseptic agent when leaving the room

Match the following precautions with their requirements for patient transport:

Airborne precautions = Transport patient out of room only when necessary and place surgical mask on the patient, if possible Droplet precautions = Transport patient out of room only when necessary and place mask on the patient if possible Contact precautions = Limit movement of the patient out of the room; patients MUST wear correct PPE when leaving

Match the following precautions with their requirements for visitors:

Airborne precautions = No specific requirements mentioned Droplet precautions = Keep visitors 3ft away from the infected person, must also wear a mask Contact precautions = No specific requirements mentioned

Match the following precautions with their associated conditions:

Airborne precautions = No specific conditions mentioned Droplet precautions = No specific conditions mentioned Contact precautions = For patients in the presence of excessive wound drainage, fecal incontinence, or other discharges from the body

Match the following precautions with their protective equipment requirements:

Airborne precautions = Healthcare workers wear a respiratory mask (N95) Droplet precautions = Healthcare workers and visitors must wear a mask Contact precautions = Healthcare workers wear gloves and a gown

Match the following precautions with their requirements for patient movement:

Airborne precautions = Keep patient in room; transport out only when necessary Droplet precautions = Transport patient out of room only when necessary Contact precautions = Limit movement of the patient out of the room

Match the following precautions with their hand hygiene requirements:

Airborne precautions = No specific requirements mentioned Droplet precautions = No specific requirements mentioned Contact precautions = Wash hands with an antimicrobial or antiseptic agent when leaving the room

Study Notes

Infection Prevention and Control

The most common mode of transmission of pathogens in healthcare settings is contact transmission.

Asepsis

The main goal of asepsis is to prevent the transmission of microorganisms.
Asepsis involves procedures and practices that reduce the number and transfer of pathogens.

Hand Hygiene

Hand hygiene should be performed before clean or aseptic technique.
The recommended duration for scrubbing hands with soap during hand hygiene is at least 15 seconds.
The best technique for hand hygiene is rubbing hands with soap and water or using an alcohol-based hand sanitizer.
Hand hygiene should be performed in situations such as before patient contact, before invasive procedures, and after contact with body fluids or mucous membranes.

Surgical Asepsis

Surgical asepsis is a technique used to keep objects and areas free from microorganisms.
A principle of sterile technique is that all objects and areas coming into contact with the surgical site must be sterile.

Personal Protective Equipment (PPE)

PPE includes gloves, gowns, masks, and eye protection.
PPE should be worn when encountering body fluids or mucous membranes, during invasive procedures, and when carrying soiled items.
Gloves should be changed during patient care when they become contaminated, are damaged, or when there is a risk of transmission.

Standard Precautions

The purpose of standard precautions is to prevent and control infection in healthcare settings.
Standard precautions include hand hygiene, use of PPE, and proper cleaning and disinfection of surfaces and equipment.
Healthcare workers should wear PPE, including gloves and gowns, when encountering body fluids or mucous membranes.

Infection Prevention Strategies

The best way to prevent and control infection in healthcare settings is through a combination of hand hygiene, use of PPE, and proper cleaning and disinfection of surfaces and equipment.
Isolation precautions should be used to prevent transmission of pathogens through the air, large droplets, and direct or indirect contact.

Test your knowledge on asepsis and infection prevention in healthcare settings. Learn about the major mode of transmission for pathogens and the importance of proper hand hygiene. Explore the differences between medical asepsis and surgical asepsis.
