Which is true of transmission-based precautions?

Transmission-Based Precautions are the second tier of basic infection control and are to be used in addition to Standard Precautions for patients who may be infected or colonized with certain infectious agents for which additional precautions are needed to prevent infection transmission.

What are standard precautions used to prevent transmission of?

Standard precautions are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes.

What are three types of transmission-based precautions used along with standard precautions?

There are three types of transmission-based precautions–contact, droplet, and airborne – the type used depends on the mode of transmission of a specific disease.

When and where should transmission-based garments be removed and why?

PPE, including the face mask, should be removed at the point of exit and not worn in corridors or when caring for other patients. For some infections, eye protection might be necessary as well (e.g. Influenza).

What are airborne precautions?

Airborne precautions apply to patients known or suspected to be infected with microorganisms transmitted by airborne droplet nuclei. Preventing airborne transmission requires personal respiratory protection and special ventilation and air handling.

How are transmission-based precautions different from standard precautions?

Standard precautions are the minimum infection prevention and control practices that must be used at all times for all patients in all situations. Transmission-based precautions are used when standard precautions alone are not sufficient to prevent the spread of an infectious agent.

Which are types of transmission-based precautions check all that apply?

There are three types of transmission-based precautions: contact precautions (for diseases spread by direct or indirect contact), droplet precautions (for diseases spread by large particles in the air), and airborne precautions (for diseases spread by small particles in the air).

What type of transmission-based precautions are recommended for patients with influenza?

Adhere to Droplet Precautions

Droplet precautions should be implemented for patients with suspected or confirmed influenza for 7 days after illness onset or until 24 hours after the resolution of fever and respiratory symptoms, whichever is longer, while a patient is in a healthcare facility.

When were Transmission-Based Precautions introduced?

The isolation guidelines issued by the Centers for Disease Control and Prevention (CDC) in 1996 created a two-tiered approach: Standard Precautions and Transmission-Based Precautions,1 which draw from protocols established in Universal Precautions (UP) and Body Substance Isolation (BSI) Precautions.

What are the 5 modes of transmission?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host.

What type of precautions prevent the spread of infectious agents in aerosol form?

Airborne precautions are used to prevent the transmission of infectious agents that are spread through the air. This is different than droplet in the size of the particle and length of time they remain in aerosolized form.

What type of transmission based precaution requires the health care worker to wear gloves and gown?

Healthcare personnel caring for patients on Contact Precautions wear a gown and gloves for all interactions that may involve contact with the patient or potentially contaminated areas in the patient’s environment.

What is an example of an illness that is transmitted by droplet transmission?

Examples of microorganisms that are spread by droplet transmission are: influenza, colds, respiratory syncytial virus (RSV) and some organisms causing pneumonia.

What PPE is needed for droplet precautions?

If you are treating a patient in droplet precautions you need to wear a mask, gown and gloves.

What type of transmission based precaution is required for MRSA?

Use Contact Precautions when caring for patients with MRSA (colonized, or carrying, and infected). Contact Precautions mean: Whenever possible, patients with MRSA will have a single room or will share a room only with someone else who also has MRSA.

What type of transmission based precaution requires the health care worker to wear a surgical string mask?

Droplet precautions means a surgical mask generally is worn to provide protection against spread of infectious, large-particle droplets that are transmitted by close contact and generally travel only short distances (up to 3 feet) from infected patients who are coughing and sneezing.

What type of transmission based precaution is required for influenza mumps and rubella?

Droplet Precautions are required for patients known or suspected to be infected with microorganisms transmitted by droplets. Droplets can be generated by coughing, sneezing, talking or during the performance of procedures (e.g. nebulisation). Examples include pertussis, influenza, rubella and mumps.
