Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: A

Rationale: Bleach solution is effective for chemical disinfection of blood spills due to its strong oxidizing properties, which kill a wide range of pathogens, including viruses and bacteria.

Isopropyl alcohol, while a disinfectant, is less effective on organic matter like blood and does not meet the required concentration for effective disinfection in this context.

Hydrogen peroxide can disinfect, but it is not as commonly used for blood spills due to its instability and potential to damage surfaces.

Formaldehyde is a potent disinfectant but is often avoided in blood spill situations due to its toxicity and potential health hazards.
