SIOUX CITY After caring for COVID-19 patients at MercyOne Siouxland Medical Center, Jordan Oeland often sits in silence replaying the day as she drives her silver Subaru home to Lawton in the dark. Before this pandemic, I could leave work and be happy with the day that I had, even if it was a bad day, said Oeland, who has worked as a registered nurse since June 2017. I know I handed my patients off to great nurses who easily could take care of them. Now, you just never know if a patient could change after you hand off. You come back the next day and they might not be there.
