<s>[INST] A patient s blood culture result showed Clostridium hastiforme. The pateint is a dialysis patient. he has a good functioning AV fistula for dialysis access. No fever. AV fistula site is atraumatic. Patient s WBC has been 12.00 for 3 months. My plan is to treat patient with Metronidazole 500 mg BID for 2 weeks. Is this an appropriate treatment? Thank You Trudy Oster NP [/INST] First of all,what is the reason for ordering blood culture when patient is not having fever. If you rule out contamination of sample, you can treat with metronidazole safely. All the best. </s>
