What is an appropriate action after applying iodine before a procedure?

Allowing the iodine to dry for at least 30 seconds after application is important because this drying time allows the antiseptic to effectively act against bacteria and reduce the risk of infection during the procedure. The efficacy of iodine as an antiseptic relies on its ability to penetrate the skin and provide a barrier against potential pathogens.

If the iodine is not given sufficient time to dry, it may not fully disinfect the area, which can compromise the sterile field needed during many medical procedures. This drying period also helps to create a more lasting antimicrobial effect, ensuring better patient outcomes.

The other options do not support proper antiseptic technique, as starting the procedure too quickly can lead to an increased risk of infection, wiping off the iodine would negate the antiseptic effect, and applying alcohol immediately could interfere with the iodine’s effectiveness and potentially lead to irritation.
