Psychotic Disorders — MCQs

A 40-year-old sexually active woman with type 2 diabetes mellitus is admitted to a hospital 2 weeks after an uncomplicated cholecystectomy for pain, itching, and erythema at the incision site. Labs show a hemoglobin A1c of 6.5%, and wound cultures reveal mixed enteric bacteria. She is treated with appropriate antibiotics and discharged after her symptoms resolve. One week later, she is re-admitted with identical signs and symptoms. While in the hospital, the patient eats very little but is social and enjoys spending time with the staff. She repeatedly checks her own temperature and alerts the nursing staff when it is elevated. One morning, you notice her placing the thermometer in hot tea before doing so. What is the most likely cause of this patient’s recurrent infection and/or poor wound healing?
