Hi! I'm an LPN on call for the endo unit....we always have a team (1 lpn and 1 rn). We take call about every 7th week-end and than about ever 8th week day. And like Endo Diva it all depends on who the Dr.s are that are on call on how much your called in. On Sunday a team was in for 18 hrs........that was terrible!! We usually can count on at least 8hrs of being called in on the week-end. Its nice money(time/and half) and $2. to carry beeper.
