Most of the answers to the physiology questions can be found in your manuals - either the printed or the online version. If you cannot find the answers there, you are able to use textbooks, the internet, colleagues or other resources to help you. The purpose of the tests is NOT to get 100% - rather it is to develop the skill of researching and trying to understand and analyze information that may be contradictory or unclear. These are skills that are important to develop to help you assist clients in understanding the options available to them and what the research says on these options. If you are unable to find anything on a test question, or do not understand the question, please contact your trainer for support.
