Not true about iodophores –
**Core Concept**
Iodophores are a type of antiseptic agent used to disinfect skin and surfaces in healthcare settings. They are a combination of iodine and a non-ionic surfactant, which allows for a more stable and less irritating solution.
**Why the Correct Answer is Right**
Iodophores, such as povidone-iodine, are effective antiseptics due to their ability to release free iodine, which then kills microorganisms through oxidation of their proteins and DNA. The iodine is slowly released from the non-ionic surfactant, allowing for a prolonged antimicrobial effect.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because iodophores are not typically used for wound cleaning; they are more commonly used for skin preparation before invasive procedures.
**Option B:** Incorrect because iodophores are not known to be highly toxic; they are generally well-tolerated and non-irritating.
**Option C:** Incorrect because iodophores are not typically used for sterilization; they are more commonly used for disinfection of skin and surfaces.
**Clinical Pearl / High-Yield Fact**
When using iodophores, it's essential to note that they can inactivate many types of bacteria, viruses, and fungi, but may not be effective against spores.
**Correct Answer: B.** Iodophores are not highly toxic.
