Kim, a nail technician at Metro Salon & Spa, has an appointment today with Rylee, who tells her, "My nails are a mess!" After washing their hands, Kim and Rylee sit down for the hand and nail analysis, and Kim identifies several issues of potential concern. Kim notices that Rylee's nail beds are blue. What should she do to determine whether Rylee's case of blue fingernails is due to poor circulation?

massage them

Explanation:

It should be understood that blue fingernails refer to discoloration of the nail bed, not the nail plate, so scrubbing the nails with a dry nail brush would definitely have no effect.

In this case, Kim, as a good nail technician,  should not based her decision on the process above, but she should instead warm or massage the nails to see whether the normal color re-turns. This will show whether Rylee's case is due to poor circulation or not.

try something like republic or democracy joined or something because its talking about a election party.
