Question 13

Your patient was admitted for a gunshot wound about a week ago.As a precautionary activity,the doctor placed her on antibiotics for a few days while recuperating.Blood specimens are drawn on the patient a couple of times a day,every day,and sent down to the microbiology lab for analysis of bacteria.Nothing has grown in culture.After her 4th day in the hospital--no fever,no infection identified--one set of blood specimens has been reported positive for a bacterium.The culture was identified by the lab as Staphylococcus epidermidis,a common organism on the skin.Predict the likely situation leading to this.
