Safety and Infection Control Flashcards

Which hepatitis virus is primarily transmitted through the fecal-oral route and poses the least occupational risk to phlebotomists?

Answer: Hepatitis A

Hepatitis A is transmitted via the fecal-oral route, not blood, so it poses minimal occupational risk during routine phlebotomy.

The Joint Commission requires at least two patient identifiers (e.g., name and date of birth) to ensure accurate specimen labeling and patient safety.

Which class of fire extinguisher should be used on an electrical fire in the phlebotomy lab?

Answer: Class C

Class C extinguishers are designed for electrical fires and use non-conductive agents that will not worsen the hazard.

When a blood culture is ordered, the skin must be disinfected with 70% isopropyl alcohol followed by which agent to achieve the highest level of antisepsis?

Answer: Povidone-iodine or chlorhexidine gluconate

Blood culture sites require a two-step prep using alcohol followed by povidone-iodine or chlorhexidine to reduce skin flora and minimize contamination.

If a phlebotomist's eye is splashed with blood, which action should be taken immediately?
