- 0Jun 20, '13 by ShrizealHi all, I'm a ER/ICU nurse and I'm wondering if anyone knows of any clinical software programs? Such as case study scenario types, medication quizzes, practice questions. I've been doing CCRN questions along with some med/surg to help me sharp on my skills. Additionally I also have a subscription with Pearls Review which is awesome and is similiar to what I'm looking for. If anyone has any ideas, please share!
