Feel free to message me if you would like.
I actually did 4 years of community nursing before going back to acute care, and now work in critical care nursing. It definitely isn't easy to get back into the swing of acute care nursing, but it can be done! What area were you thinking of going into? Med/Surg? Rehab? Anywhere in the hospital that will hire you?
<<< This is a list of competencies for the Med/Surg certification exam. Competencies are organized by system, gives you a good basis for what to review if you are just plain overwhelmed or unsure where to start.
What province are you in? I'm in BC, and I used the LearningHub, which you can access regardless of what kind of position you hold or which health authority you are employed in. Tons of mini online courses on basics like IV insertions, blood transfusions, wound care, etc.
