Catheter-related bloodstream infections arise when the catheter becomes the source of bacteria entering the bloodstream. The usual approach is to obtain blood cultures before starting antibiotics so the exact organism can be identified and therapy tailored. Once an infection is diagnosed, removing the catheter is commonly needed to eliminate the source and help clear the infection. Patients may develop fever, low blood pressure, and changes in mental status as signs of sepsis from the bloodstream infection. Because these aspects fit typical management and presentation, all of these statements are true.
