What is the only acceptable skin prep solution to use on or near the eye?

Alcohol
Iodine
Chlorhexidine
Dilute povidone-iodine

The correct answer is: Dilute povidone-iodine

The only acceptable skin prep solution to use on or near the eye is dilute povidone-iodine due to its efficacy as an antiseptic that's also safe for mucous membranes and sensitive skin areas. This solution is well-tolerated and has broad-spectrum antimicrobial activity, making it suitable for surgical procedures involving the eye or surrounding structures. While alcohol, iodine, and chlorhexidine are effective antiseptics, they are not suitable for use near the eyes. Alcohol can cause irritation and is volatile, leading to the risk of eye injury. Iodine in its concentrated form can also irritate or damage the ocular surfaces. Chlorhexidine has a risk of causing severe irritation or allergic reactions, especially if it comes into contact with the eyes. Therefore, using dilute povidone-iodine provides a safe alternative that minimizes the risk of adverse effects while ensuring effective skin disinfection.
