You are familiar with pain, and have become adept at ignoring when needed.
Whenever you have the nauseated condition, you can take a move action and a standard action, but take a –4 penalty on any check associated with an action that requires a standard to complete (such as attack rolls, weapon damage rolls, some skill checks, caster level checks, and so on). When nauseated, you cannot take full-round actions.
