Review Question - QID 109247

A 4-day-old neonate is brought to the pediatrician with vaginal discharge for the last 2 days. Her daughter has been feeding and voiding well. The neonate was delivered at 39 weeks gestation via an uncomplicated vaginal delivery and was discharged home after 2 days. The prenatal course was complicated by chlamydia in the mother during the first trimester, for which she and the partner were both treated with a confirmatory test of cure. The biological father is no longer involved in the patient's life, but her mother’s boyfriend has been caring for the baby whenever the mother rests. The neonate’s temperature is 98.5°F (36.9°C), blood pressure is 56/35 mmHg, pulse is 138/min, and respirations are 51/min. She appears comfortable, and cardiopulmonary and abdominal exams are unremarkable. There are no bruises or marks on her skin. Examination of the genitals reveals no vulvar irritation or skin changes but there is scant pink mucoid discharge at the introitus. Which of the following is the most appropriate next step in management?
