The Organisms That Cause Healthcare-Associated Infections Can Originate from a Number

The organisms that cause healthcare-associated infections can originate from a number of different sources, including other patients, the healthcare environment, healthcare workers, visitors, and the patient's own microbiota. Select the INCORRECT statement.

A) P. aeruginosa is resistant to many disinfectants and antimicrobial medications, and requires few nutrients, which enables it to multiply in environments containing little other than water.
B) A healthcare worker who is an asymptomatic carrier of a pathogen such as Staphylococcus aureus may inadvertently infect patients; sometimes personnel do not realize that they pose a risk to patients until they are implicated in an outbreak.
C) Nearly any invasive procedure can transmit organisms of a patient's normal microbiota to otherwise sterile body sites-for example, skin microbiota such as Staphylococcus epidermidis may gain access to the bloodstream.
D) Transmission of HAI-causing infectious agents may be direct through contact with others, including healthcare personnel. However, indirect transmission almost never occurs in hospitals because they are a sterile environment.
E) Healthcare personnel should routinely wash or disinfect their hands after touching one patient before going to the next. They should also wear gloves when they have contact with patient's blood, mucous membranes, broken skin, or body fluids.
