Question 1

What is the recommended hand hygiene technique after removing gloves following patient care in a hemodialysis unit?

Accepted Answer

Wash hands with soap and water or use alcohol-based hand rub immediately after glove removal

Answer

Hands must be washed or sanitized immediately after removing gloves because gloves can have micro-tears and removal itself can contaminate hands.

Question 2

A new patient has been identified as hepatitis C positive. What infection control precautions should be implemented in the hemodialysis unit?

Accepted Answer

Cohort the patient with other HCV-positive patients and use dedicated machines

Answer

CDC recommends cohorting HCV-positive patients in a dedicated area or machine due to hemodialysis-specific transmission risks, in addition to standard precautions.

Question 3

What is the most common source of catheter-related bloodstream infections (CRBSI) in hemodialysis patients?

Accepted Answer

Contamination of catheter hubs during connection/disconnection procedures

Answer

The majority of CRBSIs originate from contamination of catheter hubs during the frequent connection and disconnection required for hemodialysis.

Question 4

What is the proper technique for disinfecting the skin before needle insertion for arteriovenous fistula cannulation?

Accepted Answer

Apply chlorhexidine gluconate in a circular motion and allow to dry completely before needling

Answer

Chlorhexidine gluconate applied with friction and allowed to air dry provides the most effective skin antisepsis before cannulation, reducing infection risk.

Question 5

What action should be taken if a hemodialysis staff member receives a needlestick injury from a used dialysis needle?

Accepted Answer

Immediately wash the wound, report to supervisor, complete an incident report, and seek post-exposure evaluation

Answer

Needlestick injuries require immediate wound care, incident reporting, and medical evaluation for post-exposure prophylaxis (PEP) potential regardless of known source patient status.
