INFECTION CONTROL, RENAL, DIALYSIS & ACCESS Questions 1 – 100+
1. What is an infection?
A. An allergic response to medication.
B. An invasion of body tissue by organisms invisible to the eye.
C. A genetic disorder.
D. A metabolic imbalance.
CORRECT ANSWER B — An invasion of body tissue by organisms invisible to the eye.
RATIONALE Infection occurs when microorganisms (bacteria, viruses, fungi) invade and multiply within body tissues,
potentially causing disease.
2. Dialysis surfaces must be disinfected with what solution?
A. 1:10 bleach solution.
B. 1:100 bleach solution.
C. 70% alcohol.
D. 3% hydrogen peroxide.
CORRECT ANSWER B — 1:100 bleach solution.
RATIONALE A 1:100 dilution of sodium hypochlorite (bleach) is the standard disinfectant for dialysis surfaces. Large blood
spills (>10 mL) require 1:10 bleach solution.
, 3. What is aseptic technique?
A. Cleaning visible dirt only.
B. Practices minimizing contamination by pathogens under controlled conditions.
C. Using only sterile gloves.
D. Rapid disinfection between patients.
CORRECT ANSWER B — Practices minimizing contamination by pathogens under controlled conditions.
RATIONALE Aseptic technique prevents microbial contamination. Key principle: sterile + sterile = sterile; sterile + clean =
clean; sterile/clean + dirty = dirty.
4. Three bloodborne pathogens found in a dialysis unit are:
A. Influenza, TB, RSV.
B. Hepatitis B, Hepatitis C, HIV.
C. MRSA, VRE, C. diff.
D. E. coli, Salmonella, Shigella.
CORRECT ANSWER B — Hepatitis B, Hepatitis C, HIV.
RATIONALE These three bloodborne viruses are the primary occupational risks in dialysis. HBV can survive outside the
body up to 7 days and requires isolation dialysis.
5. What is an exposure incident?
A. Any patient complaint.
B. A bloody/body fluid splash to eyes, nose, mouth, or non-intact skin.
C. Equipment malfunction.
D. A patient fall.
CORRECT ANSWER B — A bloody/body fluid splash to eyes, nose, mouth, or non-intact skin.
RATIONALE Exposure requires immediate washing/rinsing, reporting to clinical manager, and seeking medical treatment
for evaluation and prophylaxis.
6. Why are Hep B patients dialyzed in an isolation room?
A. They require special equipment.
B. HBV is extremely contagious and survives outside the body up to 7 days.
C. They are immunocompromised.
D. Treatment is longer.
CORRECT ANSWER B — HBV is extremely contagious and survives outside the body up to 7 days.
RATIONALE Hepatitis B surface antigen (HbsAg) positive patients require dedicated machines and isolation to prevent
transmission. HCV patients may dialyze in the clinical area.
