She was at 40 weeks and 2 days gestation at the time of delivery. The patient is now complaining of purulent discharge and continued heavy bleeding. She also notes difficulty and discomfort with urination. The patients prenatal course was complicated by one episode of pyelonephritis, which was treated with intravenous ceftriaxone and suppression nitrofurantoin for the remainder of the pregnancy. The patient has a medical history of generalized anxiety disorder and atopic dermatitis. On the third postpartum day, her temperature is 101.2F 38.4C, pulse is 112min, blood pressure is 11871 mmHg, and respirations are 13min. Exam reveals that she is uncomfortable and diaphoretic. Her lochia is purulent with several blood clots, and her uterus is slightly boggy and soft. There is mild tenderness with uterine manipulation. Which of the following is the best next step in management for this patients condition?? A: Urinalysis and urine culture, B: Endometrial culture, C: Clindamycin, D: Clindamycin and gentamicin, E: Ceftriaxone,  <response>: This is a postpartum patient who is 3 days status post C-section. She is now presenting with concerning symptoms including purulent vaginal discharge, heavy bleeding, dysuria, fever, tachycardia, and uterine tenderness. The most likely diagnosis is endometritis, which is an infection of the uterine lining that can occur after C-section. Key points from the stem that support this diagnosis are the purulent lochia, uterine tenderness, and fever on postpartum day 3. The best next step would be to obtain cultures to identify the causative organism, and start empiric antibiotic therapy to cover likely pathogens. Endometrial culture would directly sample the uterine cavity and identify the pathogen. Broad spectrum antibiotics like clindamycin and gentamicin would empirically cover common causes of endometritis like streptococcus, staph, and gram negatives. Urinalysis and urine culture would not directly sample the uterine cavity and would not be the best next step. Ceftriaxone may not provide adequate gram positive coverage on its own.D: Clindamycin and gentamicin
