Can I make a standard action single attack using power attack vital strike and then use the amulet to make a swift action attack also using vital strike?
The amulet says this
This glass teardrop hangs on a platinum chain and can be used once per day to grant a surge of power. This surge can be used in one of two ways. As a swift action, the wearer of the amulet can make one melee or ranged attack at his highest attack bonus.
I imagine furious focus wouldn't apply to the swift action after having used power attack in the standard action, but can I vital strike again?
