Pseudomonal infection should not be cleaned by:
**Core Concept**
Antimicrobial stewardship and infection control principles emphasize the importance of proper hand hygiene and surface disinfection to prevent the spread of multidrug-resistant organisms, such as Pseudomonas aeruginosa. Effective cleaning and disinfection are crucial to control outbreaks and prevent nosocomial infections.
**Why the Correct Answer is Right**
Pseudomonas aeruginosa is notoriously resistant to many disinfectants and cleaning agents. Using the wrong cleaning agent can lead to the survival and spread of this pathogen. Chlorine-based bleach solutions are effective against Pseudomonas, but other agents, such as quaternary ammonium compounds (quats) or alcohol-based disinfectants, may not be sufficient to kill Pseudomonas. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) recommend using EPA-registered disinfectants that are effective against Pseudomonas for cleaning and disinfection.
**Why Each Wrong Option is Incorrect**
* **Option A:** Chlorine-based bleach solutions are effective against Pseudomonas, making this a correct option for cleaning and disinfection.
* **Option B:** Quaternary ammonium compounds (quats) are often used for cleaning and disinfection, but they may not be effective against Pseudomonas, making this a potential incorrect option.
* **Option D:** This option is not provided, so we cannot evaluate its accuracy.
**Clinical Pearl / High-Yield Fact**
When cleaning and disinfecting surfaces contaminated with Pseudomonas, always check the product label to ensure it is EPA-registered and effective against Pseudomonas aeruginosa. Remember the "5-Second Rule": clean and disinfect for at least 5 seconds to ensure effective killing of microorganisms.
**Correct Answer:** B.
