 Donna arrives at Holby City Hospital as a staff nurse on the general surgery ward , making a poor first impression by being disorganised and insolent . Mistakenly believing that living with her superior will ensure her an easy time at work , Donna invites herself to move in with nurse Lisa Fox ( Luisa Bradshaw @-@ White ) . The two have a strained relationship : within weeks , Donna is evicted for falling behind on her rent , and when she is later allowed to move back in , she lets bailiffs take Lisa 's possessions after failing to keep up her own loan repayments . Forced to run a shift in charge of the hospital 's Acute Assessment Unit as recompense , Donna struggles to manage and learns a new respect for Lisa . During this period , Donna has a friendship with midwife Mickie Hendrie ( Kelly Adams ) . Mickie is questioning her sexuality , and the two have sex while drunk . Mickie is disappointed when Donna states that it was just a one @-@ night stand , but they are able to reconcile their friendship . When the general surgery ward is downsized , Donna is forced to reapply for her job . Although she gives a good interview and impresses Lisa , other candidates have more experience , so she is unable to retain her position and has to work as a bank nurse .
