CCHT Infection Control 3

Question 1

What is the recommended hepatitis B vaccination schedule for new hemodialysis patients, and what titer confirms adequate immunity?

Accepted Answer

Double-dose 4-dose schedule (0, 1, 2, 6 months); anti-HBs 10 mIU/mL or greater

Answer

ESRD patients have impaired immune response; they require a double-dose 4-dose HBV vaccine series with protective immunity defined as anti-HBs 10 mIU/mL or greater.

Question 2

Which organism is most commonly responsible for catheter-related bloodstream infections in hemodialysis patients?

Accepted Answer

Staphylococcus aureus (including MRSA)

Answer

Staphylococcus aureus, including methicillin-resistant strains (MRSA), is the most common cause of catheter-related bloodstream infections in hemodialysis patients.

Question 3

What is the purpose of maintaining a log of dialysis machine disinfection in the hemodialysis unit?

Accepted Answer

To document compliance with infection control protocols and provide traceability for outbreak investigations

Answer

Disinfection logs provide regulatory compliance documentation and enable traceback during infection outbreaks to identify potential sources.

Question 4

A patient arrives for treatment with an exit site infection at their tunneled dialysis catheter. What assessment findings suggest the infection may require catheter removal?

Accepted Answer

Purulent drainage, tunnel track tenderness, fever, and bacteremia

Answer

Signs of catheter tunnel infection (purulence, tunnel tenderness, systemic infection/bacteremia) typically indicate catheter removal is necessary as antibiotics alone are insufficient.

Question 5

What is the significance of the NHSN (National Healthcare Safety Network) reporting requirement for hemodialysis facilities?

Accepted Answer

It is mandatory reporting of infections and events to enable national surveillance and benchmarking

Answer

NHSN reporting is mandatory for all Medicare/Medicaid certified hemodialysis facilities to track infection rates, enable national comparison, and identify outbreak patterns.
