Exam 3: The Laboratory Role in Infection Control

When an outbreak is suspected, all the following steps are taken in investigating that event, except

Prisoners or people housed in behavioral health facilities are more likely to contract infections with pathogens from their intimate contact with blood and body fluids. A likely pathogen may be

Laboratory technologists must not only keep themselves educated in their contribution to the infection control team, they must keep

What is pulsed-field gel electrophoresis?

In an outbreak investigation and in the collection of routine surveillance data, what sorts of activities are critical?

An index case is

An example of an emerging disease is

Waterborne illnesses that may be associated with contaminated drinking water or recreation water include all the following, except

This program involves a close watch of only specific, high-risk, high-volume procedures for nosocomial infections.

Organisms that represent public health concerns can be recovered from patients in an acute care hospital. All of the following isolates are considered significant or major public health concerns that are reportable to public health jurisdictions to follow up as a potential outbreak, except

A microbiology technologist is working at the bench and notices that a patient from the cardiac intensive care unit (CICU) grows a Klebsiella pneumoniae bacterium that is an extended-spectrum $\beta$ -lactamase-producing isolate. This technologist would advise the physician to

In acute care hospitals, transmission of pathogens as a result of treatment occurs as all the following "classifications" of infections, except

To keep abreast of all infections that occur in the hospital, infection control practitioners set up surveillance programs. These surveillance programs look at this parameter to determine if there are more or fewer infections in a given period.

Although environmental cultures are not usually performed because the environment is rarely implicated in disease transmission, they occasionally are useful. Samples will be taken from all of the following, except

This is practiced throughout the hospital and mandates safety for all personnel when handling blood and body fluids.

The role of the microbiology laboratory is to perform cultures and provide culture results to health care providers. The microbiology laboratory also has the responsibility to

An iatrogenic infection is one that

Information that the microbiology laboratory can provide to infection control practitioners includes

The hospital infection control committee will expect reports from the laboratory that deal with all the following, except

Organisms that are frequently encountered as causes of health care-associated infections in acute care settings include all the following organisms, except
