Which of the following is not considered an accepted disinfectant by the CDC?

The choice indicating that alcohol (specifically 60-70% ethanol) is not considered an accepted disinfectant by the CDC is not accurate. In fact, alcohol, particularly in this concentration, is recognized as an effective disinfectant for use in healthcare settings. This concentration is effective against a broad range of pathogens, making it a suitable choice for surface disinfection and hand hygiene.

The correct answer to the question would be benzalkonium chloride. The CDC does not endorse benzalkonium chloride as a reliable disinfectant in many applications, particularly when dealing with certain resistant organisms. It is often seen as less effective than other agents for disinfection purposes, especially in high-risk settings.

Sodium hypochlorite is recognized by the CDC as a strong disinfectant effective against many pathogens, including viruses and bacteria. Complex phenols are also considered effective disinfectants used in various healthcare settings. Thus, while alcohol has a role in disinfection, understanding its limitations is vital, but it remains an accepted disinfectant according to CDC guidelines.
