What is the recommended hand hygiene technique after removing gloves following patient care in a hemodialysis unit?
Answer: Wash hands with soap and water or use alcohol-based hand rub immediately after glove removal
Hands must be washed or sanitized immediately after removing gloves because gloves can have micro-tears and removal itself can contaminate hands.
A new patient has been identified as hepatitis C positive. What infection control precautions should be implemented in the hemodialysis unit?
Answer: Cohort the patient with other HCV-positive patients and use dedicated machines
CDC recommends cohorting HCV-positive patients in a dedicated area or machine due to hemodialysis-specific transmission risks, in addition to standard precautions.
What is the most common source of catheter-related bloodstream infections (CRBSI) in hemodialysis patients?
Answer: Contamination of catheter hubs during connection/disconnection procedures
The majority of CRBSIs originate from contamination of catheter hubs during the frequent connection and disconnection required for hemodialysis.
What is the proper technique for disinfecting the skin before needle insertion for arteriovenous fistula cannulation?
Answer: Apply chlorhexidine gluconate in a circular motion and allow to dry completely before needling
Chlorhexidine gluconate applied with friction and allowed to air dry provides the most effective skin antisepsis before cannulation, reducing infection risk.
What action should be taken if a hemodialysis staff member receives a needlestick injury from a used dialysis needle?
Answer: Immediately wash the wound, report to supervisor, complete an incident report, and seek post-exposure evaluation
Needlestick injuries require immediate wound care, incident reporting, and medical evaluation for post-exposure prophylaxis (PEP) potential regardless of known source patient status.
During a hemodialysis treatment, the technician notices that the dialysate has a cloudy appearance. What is the most appropriate action?
Answer: Stop treatment, do not return blood, and report to the charge nurse and biomedical staff
Cloudy dialysate is abnormal and may indicate contamination, bacterial growth, or incorrect concentrate mixing; treatment must be stopped immediately.
