Can you recommend a good critical care review course (preferably distance learning or online) to prepare for re-entry into nursing after 4yrs sahm (stay at home mom). I have been a nurse since 1991. Most of my experience is in the ICU setting. I've worked SICU/CCU, Trauma (short time), Home Health and Wound care. I'd like to return to ICU. Anyone else out there recently made the transition? I would appreciate any advice you can give.
