A 29-year-old woman is recovering on the obstetrics floor after the vaginal delivery of 8-pound twin boys born at 42 weeks gestation. The patient is fatigued but states that she is doing well. Currently, she is complaining that her vagina hurts. The next morning, the patient experiences chills and a light red voluminous discharge from her vagina. She states that she feels pain and cramps in her abdomen. The patient's medical history is notable for diabetes which was managed during her pregnancy with insulin. Her temperature is 99.5°F (37.5°C), blood pressure is 107/68 mmHg, pulse is 97/min, respirations are 16/min, and oxygen saturation is 98% on room air. Laboratory values are obtained and shown below. Hemoglobin: 12 g/dL Hematocrit: 36% Leukocyte count: 9,750/mm^3 with normal differential Platelet count: 197,000/mm^3 Serum: Na+: 139 mEq/L Cl-: 101 mEq/L K+: 4.2 mEq/L HCO3-: 23 mEq/L BUN: 20 mg/dL Glucose: 111 mg/dL Creatinine: 1.1 mg/dL Ca2+: 10.2 mg/dL AST: 12 U/L ALT: 10 U/L Which of the following is the most appropriate next step in treatment for this patient?
Supportive therapy only
Vancomycin and clindamycin
Cefoxitin and doxycycline
Vancomycin and gentamicin
Supportive therapy only
This patient is presenting with a normal postpartum period which is managed with supportive therapy only.

A normal postpartum period is associated with breast tenderness, chills, edema, and abdominal cramps from a contracting uterus. Vaginal discharge (lochia) is normal in this phase and progresses from a red color (lochia rubra) to a clear/fluid appearance (lochia serosa) to a white color (lochia alba). No management other than supportive therapy is needed during this period. Symptoms that indicate additional intervention may be necessary include fever, foul-smelling drainage, or hypotension.

Fletcher et al. review the evidence regarding normal lochia after pregnancy. They discuss how this discharge can occur for up to 24-36 days after delivery. They recommend understanding normal discharge patterns to allow for the identification of pathologic conditions.

Incorrect Answers:
Answer A: Cefoxitin and doxycycline can be used to treat postpartum endometritis in which the suspected organism is Chlamydia trachomatis or Neisseria gonorrhoea. Suspect these organisms in a patient with risky sexual behavior.

Answer B: Clindamycin and gentamicin offer broad-spectrum coverage for endometritis, which presents with fever, abdominal tenderness, and a foul-smelling vaginal discharge. This patient has no evidence of infection at this time.

Answer D: Vancomycin and clindamycin is not a typical broad-spectrum antibiotic pair that is used routinely. Both of these agents are often effective against MRSA but are typically not used concurrently.

Answer E: Vancomycin and gentamicin offer broad-spectrum antibiotic coverage and can be used for bacterial endocarditis which presents with fever and a new murmur in a high-risk individual (such as those who use IV drugs).

Bullet Summary:
A normal postpartum period presents with chills, abdominal cramps, and lochia (rubra, serosa, or alba) and is managed with supportive care.
