Takela Gardner began her nursing career just two years ago, but her patients already think she's a seasoned nurse. A registered nurse at a University of Arkansas for Medical Sciences (UAMS) facility in Little Rock, Gardner told CNN she's had to essentially learn nursing on the fly during the Covid-19 pandemic, which she said began eight months into her nursing career. Not only that, but seeing constant death, working long shifts and having a shortage of health care staff -- specifically nurses -- have left Gardner burnt out.
