Section 1: Infection Control & Environmental Safety
Question 1
What is the most common route by which healthcare-associated pathogens are transmitted in a
hemodialysis clinic?
• A) Airborne transmission
• B) Contact transmission
• C) Vector-borne transmission
• D) Droplet transmission
Correct Answer: B) Contact transmission
Rationale: Contact transmission—specifically hands touching contaminated surfaces,
equipment, or patients and then touching another patient or supply—is the primary mode of
transmitting Healthcare-Associated Infections (HAIs) in dialysis units. Strict hand hygiene and
changing gloves between patient contact points are crucial to prevent cross-contamination.
Question 2
,What is the single most effective intervention for preventing the spread of infection in a
outpatient dialysis clinic?
• A) Wearing double gloves during all procedures
• B) Performing proper hand hygiene before and after every patient contact
• C) Soaking all lines in bleach prior to disposal
• D) Prophylactic administration of oral antibiotics to high-risk patients
Correct Answer: B) Performing proper hand hygiene before and after every patient contact
Rationale: Hand hygiene using either soap and water or an alcohol-based hand rub (60%–90%
alcohol) is universally recognized as the single most effective method for controlling healthcare-
acquired infections.
Question 3
What organism is the most frequent cause of bacterial vascular access infections in hemodialysis
patients?
• A) Pseudomonas aeruginosa
• B) Clostridioides difficile
• C) Staphylococcus aureus (including MRSA)
• D) Escherichia coli
Correct Answer: C) Staphylococcus aureus (including MRSA)
Rationale: Staphylococcus aureus and Methicillin-Resistant Staphylococcus aureus (MRSA)
naturally colonize human skin and nostril mucosa. Because vascular access sites break skin
integrity, S. aureus represents the leading pathogen responsible for bacteremia and access sepsis.
Question 4
True or False: Casual contact with a patient (such as shaking hands or handing over a blanket)
requires glove use.
Correct Answer: False
Rationale: Casual contact does not mandate glove usage unless there is anticipated contact with
blood, bodily fluids, non-intact skin, or contaminated surfaces. However, performing hand
hygiene before and after touching the patient remains mandatory.
Question 5
, Which dilution strength of bleach is required for surface disinfection when cleaning up blood
spills larger than 10 mL?
• A) 1:100 bleach solution
• B) 1:10 bleach solution
• C) Undiluted 100% bleach
• D) 70% isopropyl alcohol
Correct Answer: B) 1:10 bleach solution
Rationale: A 1:10 sodium hypochlorite (bleach) solution is required for large blood spills
(greater than 10 mL) and for spore-forming organisms like C. difficile to ensure effective
decontamination of heavy organic loads. A 1:100 solution is suitable for routine routine surface
wipe-downs.
Question 6
When caring for a Hepatitis B surface Antigen (HBsAg) positive patient, which dedicated
isolation practice must be enforced?
• A) The patient must dialyze in a negative pressure room with door sealed.
• B) The patient must be dialyzed in a separate dedicated area on a dedicated machine,
cared for by staff assigned only to HBsAg-positive patients.
• C) The patient must wear an N95 respirator during connection and disconnection.
• D) The patient's dialyzer must undergo reuse processing.
Correct Answer: B) The patient must be dialyzed in a separate dedicated area on a dedicated
machine, cared for by staff assigned only to HBsAg-positive patients.
Rationale: CDC and DaVita policy mandate dedicated isolation rooms/areas and dedicated
personnel for HBsAg-positive patients to prevent transmission of HBV, which is highly
infectious and resilient on environmental surfaces. Staff caring for HBsAg-positive patients
cannot concurrently care for HBV-susceptible patients during the same shift.
Question 7
What three laboratory tests comprise the mandatory Hepatitis B serologic panel drawn upon
admission to a dialysis unit?
• A) HBsAg, HBsAb (Anti-HBs), and Total HBcAb (Anti-HBc)
• B) HAV-IgM, HCV-RNA, and HIV-1/2
• C) ALT, AST, and Bilirubin
