He is afebrile and the vital signs are within normal limits. A contrast computed tomography CT scan of the abdomen reveals a mass in the pancreatic head. A blood test for carbohydrate antigen CA19-9 is positive. The patient is admitted to the intensive care unit ICU and undergoes surgical decompression of the biliary tract. He is placed on total parenteral nutrition TPN. On day 4 after admission, his intravenous access site is found to be erythematous and edematous. Which of the following microorganisms is most likely responsible for this patients intravenous IV site infection??

He underwent surgical decompression of the biliary tract and was started on TPN. He then developed an IV site infection. The key findings pointing to the likely organism are:- IV site infection in an immunocompromised hospitalized patient on TPN- No mention of breaks in sterile technique, so likely an opportunistic organismThis clinical picture is most consistent with a catheter-related bloodstream infection, likely from an opportunistic organism like Candida parapsilosis which can thrive on TPN and infect immunocompromised hosts.D: Candida parapsilosis
