Question 1

According to CDC guidance, CRE cases should be reported to which entity?

Accepted Answer

The local or state health department per jurisdictional requirements

Answer

CRE reporting requirements vary by state, but most jurisdictions require facilities to report CRE cases to local or state health departments to enable public health surveillance.

Question 2

Enhanced Barrier Precautions (EBP), as recommended by the CDC for nursing homes, require gown and gloves during:

Accepted Answer

High-contact resident care activities for residents with specific MDROs

Answer

Enhanced Barrier Precautions call for gown and gloves during high-contact care activities (e.g., wound care, bathing) for residents with targeted MDROs, even without active infection.

Question 3

Which of the following mechanisms BEST explains carbapenem resistance in Klebsiella pneumoniae carbapenemase (KPC)-producing organisms?

Accepted Answer

Production of a carbapenemase enzyme that hydrolyzes carbapenem antibiotics

Answer

KPC-producing organisms produce a serine carbapenemase enzyme encoded by the blaKPC gene that hydrolyzes and inactivates carbapenem antibiotics.

Question 4

Long-term care facility (LTCF) residents with MDROs who do not have uncontrolled secretions or draining wounds generally:

Accepted Answer

May participate in common activities without special precautions beyond standard precautions

Answer

LTC residents with MDROs who have no uncontrolled secretions or wounds can participate in communal activities; isolation should be based on hygiene and behavior, not MDRO status alone.

Question 5

Which surveillance method uses automated extraction of microbiology data to identify MDRO trends in real time?

Accepted Answer

Laboratory-based electronic surveillance

Answer

Laboratory-based electronic surveillance uses automated extraction from the laboratory information system (LIS) to continuously monitor MDRO incidence rates without manual chart review.
