During afternoon rounds, a physician evaluates a 54-year-old female patient due to an episode of elevated temperature. The patient underwent an uncomplicated laparoscopic cholecystectomy three days ago for recurrent biliary colic. She has been tolerating a regular diet and her pain is well controlled with oral medications. Her current vital signs show a temperature of 38.3°C (100.9°F), heart rate of 92/min, blood pressure of 128/82 mmHg, and respiratory rate of 14/min. Auscultation of the lungs reveals clear breath sounds bilaterally. Her abdomen is soft and non-tender, and the surgical port sites are healing appropriately without signs of infection. Inspection of the right distal forearm, where a peripheral venous catheter has been in place since admission, demonstrates localized tenderness, induration, and a 3-centimeter streak of erythema tracing the course of the vein. There is no fluctuance or purulent discharge. Which of the following is the most appropriate next step in management?
- Remove the peripheral venous catheterCevap
- BInitiate empiric intravenous vancomycin therapy
- CObtain a lower extremity venous duplex ultrasound
- DAdminister a therapeutic dose of enoxaparin
- EPerform a computed tomography scan of the abdomen and pelvis
