What constitutes a "lawful self-defense" action?

A defendant acts in lawful self-defense if: "1. The defendant reasonably believed that [she] was in imminent danger of suffering bodily injury [or was in imminent danger of being touched unlawfully]; [] 2. The defendant reasonably believed that the immediate use of force was necessary to defend against that danger; [] AND [] 3. The defendant used no more force than was reasonably necessary to defend against that danger." (CALCRIM No. 3470; People v. Clark (2011) 201 Cal.App.4th 235, 250.)
