Animator.SetTrigger more than once in a frame

I use Animator.SetTrigger to play an animation on a player with an Animator. Sometimes he may play more than one animation in a frame, and I want he play the last one.

He uses a skill, I let him play a skill animation, and an enemy may attack him later in the same frame, so he will play a hurt animation.

An enemy attack him , he plays a hurt animation, but he use a skil that grants immunity from any damage later in the same frame, so he will play a skill animation.

The problem is not always the last animation is played. Can anyone tell me how to do? Thank you!
