Where did you take your program?
Although not required, consider being prepared with more than just "the script" for assessment. Make sure you know all applicable medications, name, dose, medical control, route, indications, contraindications, etc. When given vitals, pause, and think about what they may mean for the patient (remember, you are demonstrating clinical practice, not just a script, so share your clinical impression if/when you have one). Make sure (on all stations) to verbalize everything so they examiner can hear and understand your thought process.
Fully familiarize yourself with all necessary equipment and supply, before and on the day of. For equipment heavy stations, prepare what you expect to need at the beginning of the station.
