How Do I Pick 1 Single Child From A "for i, v in pairs() do" loop?

Hey Devs I Made A Script And Now I Am Having Problems On How DO I Select Only 1 Child From A for i,v loop

Local Script

local TEST = game.ReplicatedStorage.test
wait(5)
print("Script Started")

for i, v in pairs(game.Workspace:GetChildren()) do
    if v:IsA("Part") then
        if v.Position == v.Position then
            TEST:FireServer(v)
        end
    end
end

Script

local TEST = game.ReplicatedStorage.test

TEST.OnServerEvent:Connect(function(player,v)
    if v.Name == "Base" then
        return false
    else
        print(v.Name)
    end
end)

Thanks
