Question

when should hand antiseptics be used?
when gloves arent available
instead of handwashing
after handwashing
before handwashing

Explanation:

Hand antiseptics are used to reduce the number of microorganisms on the hands. They are typically used after handwashing to further decrease the microbial load. Handwashing is the primary method for cleaning hands, and antiseptics are an additional measure. Gloves are not a substitute for hand - hygiene practices including antiseptics. And antiseptics are not a replacement for handwashing.

Answer:

After handwashing
