I've been copying the FAQ's and putting them into three hole binders at work. They are used as supplemental to the orientation manual. Staff on several units at 2 hospitals use them PRN.
www.icufaqs.org - "Reading EKGs II" is a great addition.
I bought the bound version for an RN when she got her BSN as a graduation gift.
When there is time on our night shift we study the FAQ's, and the policy and Procedure manuals.
