State Skills & Written Exam in a Week. I still have questions..!.

okay so ive been reading up on my nursing aide candidate booklet and in most of the skills it states to remove gloves, wash hands n THEN come back lower the bed into lowest position and give call light. shouldnt i be removing gloves then putting the bed in lowest position and giving the call light and then washing hands? because you cant leave them alone without either one being done.. and if i do wash my hands first, do i put up the siderails so they dont roll out of bed? ive been out of the class for 2 months so im a little rusty =/ also when im making an occupied bed.. when rolling the dirty bottom sheet under the client and then putting the clean one on and rolling it also under client does it go underneath the dirty one or on top? Do you wear gloves when doing an occupied bed change?

this information would be great =) i emailed my instructor, but shes out of the office on vacation during this time so im kinda screwed. any other pointers and helpful information would be great! thanks everybody
