A 39-year-old woman, gravida 4, para 0, at 10 weeks’ gestation was admitted to the obstetrics ward for fever, dysuria, back pain, and a dry cough that she had for 3 weeks. Medical history was significant for pituitary microadenoma, nephrolithiasis status after lithotripsy, and three prior spontaneous abortions. She worked in a daycare center, was married, and denied a history of excessive alcohol use, cigarette smoking, or illicit drugs. Because of her history of nephrolithiasis, the patient was started on ceftriaxone for presumed urinary tract infection. At the time of admission, she was noted to have a temperature of 38.2°C, BP of 112/61 mm Hg, heart rate of 111 beats/min, and an oxygen saturation breathing ambient air of 100%. Admission chest radiograph was not done to prevent radiation exposure to the fetus. Laboratory results were notable for a WBC count of 8 and an unremarkable urinalysis.
