What is an exposure incident? Correct Answer: A bloody/body fluid splash/spray occurring to
the eyes nose or mouth, or non-intact skin.
What steps should you take if you have been exposed to the fluids? Correct Answer: Wash/rinse

How can the viral form of hepatitis be spread? Correct Answer: Hep A- via contaminated food
and the oral-fecal route
Hep B & C- via exposure to blood/body fluids
Why are patients with Hep B dialyzed in isolation room? Correct Answer: Extremely
contagious, lives outside the body for extended periods. (up to 7 days)
Why do we dialyze Hep C patients in the clinical area? Correct Answer: Not as contagious as
Hep B. HCV is not known to survive very long outside the body
, What blood test indicates infection with Hep B? Correct Answer: HbsAg test for Hep B antigen,
indicates actual viral presence.
What blood test indicates the presence of immunity against Hep B? Correct Answer: HbsAb test
for antibodies, indicates immunity against Hep B
Which vaccine provides long-term immunity to Hep B? Correct Answer: Series of multiple
injections of either Recombivax or Engerix
Positive Tuberculin skin test, or exposure to TB Correct Answer: Patients with active TB are
contagious.
How is Tuberculosis spread? Correct Answer: Droplet of nuclei produced from infected
individuals when they cough, sneeze, speak, or sing
How do you prevent TB in a dialysis clinic? Correct Answer: Patients who have active TB
cannot dialyze in a hemodialysis clinic. 3 consecutive (-) sputum cultures before returning to the
clinic
What is VRE (Vancomycin-resistant enterococci)? Correct Answer: Gram negative, round-
shaped bacteria that commonly live in the intestinal tract. Can cause infection anywhere in the

What precautions should you take when caring for MRSA/VRE? Correct Answer: PPE, hand
sanitation before next task, dedicated gown should be worn. CVC dressings should be disposed
of in red BIO. DO NOT need isolation. Hands should be washed for 40-60 seconds.
What is C-Diff? Correct Answer: Clostridium difficile, hand washing is required.
Why is hand hygiene important? Correct Answer: Single most important infection control
measure to prevent the spread of infection.
What are the anatomical structures of the urinary system in order of urine flow? Correct Answer:
2 kidneys, 2 ureters, 1 bladder, and 1 urethra
What are the functions of a healthy kidney? Correct Answer: Removal of waste products
(creatinine, urea, and uric acid). Regulate fluid, acid base, and electrolytes.
What is urea? Correct Answer: By-product of protein metabolism
What is creatinine? Correct Answer: By-product of muscle metabolism
