What is statute of limitations of civil judgments in Iowa?

According to http://www.expertlaw.com/library/limitations_by_state/Iowa.html

The following periods represent a small sample of the statutory limitations periods in Iowa. Please note that it may be possible to bring multiple causes of action from a single incident of wrongful conduct, and thus even if it appears that the relevant statute of limitations has run it may remain possible to bring a different claim. Also, there may be an exception to the standard limitations period that applies to any given situation. The following list is provided by way of example. If you wish to know how the statute of limitations applies to a specific situation, you should verify the statutory time period and its relevance to your situation with a qualified Iowa lawyer.
