Question 16

1. Add ampicillin to the current regimen. (correct answer)
2. Perform a dilation and curettage.
3. Obtain a CT scan of the abdomen and pelvis.
4. Discontinue current antibiotics and switch to vancomycin.

Explanation: Postpartum endometritis is typically a polymicrobial infection. The standard treatment with clindamycin (for anaerobes and Gram-positives) and gentamicin (for Gram-negatives) is effective for most cases. When a patient fails to respond within 48-72 hours, antibiotic resistance should be suspected. The most common resistant organism is Enterococcus, which is not covered by clindamycin or gentamicin. Therefore, adding ampicillin to the regimen to cover Enterococcus is the appropriate next step. Imaging or surgical intervention is considered if there is suspicion of an abscess or septic pelvic thrombophlebitis.

Question 17

1. D-dimer assay.
2. Electrocardiogram.
3. Chest X-ray.
4. Echocardiogram. (correct answer)

Explanation: The patient's presentation in the late postpartum period with signs and symptoms of acute congestive heart failure (dyspnea, orthopnea, JVD, crackles, edema) is highly suspicious for peripartum cardiomyopathy (PPCM). The diagnosis of PPCM is confirmed by an echocardiogram demonstrating new-onset left ventricular systolic dysfunction, typically defined as an ejection fraction less than 45%. While a chest x-ray would show signs of heart failure (e.g., cardiomegaly, pulmonary edema), it does not confirm the underlying cardiac dysfunction.

Question 18

1. Combined oral contraceptive pills, as the postpartum hypercoagulable state has resolved.
2. Etonogestrel implant. (correct answer)
3. Natural family planning methods, as hormonal options are too risky.
4. A diaphragm, initiated after waiting for complete uterine involution at 12 weeks.

Explanation: This patient has a contraindication to estrogen-containing contraceptives due to her history of migraine with aura, which is associated with an increased risk of ischemic stroke. Therefore, combined oral contraceptives are not an option. The etonogestrel implant is a progestin-only, long-acting, highly effective contraceptive that is safe during breastfeeding and in women with migraine with aura. It is a superior choice compared to less effective methods like a diaphragm or natural family planning for a patient desiring high efficacy.

Question 19

1. Place the IUD today during the clinic visit. (correct answer)
2. Delay placement until she has her first menses postpartum.
3. Schedule placement for 12 weeks postpartum to minimize expulsion risk.
4. Prescribe a progestin-only pill until she stops breastfeeding, then place the IUD.

Explanation: At 4-6 weeks postpartum, the uterus is sufficiently involuted, and the risk of uterine perforation with IUD insertion returns to baseline. It is safe and convenient to place the IUD at the 6-week postpartum visit. There is no need to wait for the return of menses, which can be delayed for many months in breastfeeding women. The levonorgestrel-releasing IUD is safe during lactation and is an excellent choice for this patient, as it may also help with her underlying dysmenorrhea.

Question 20

1. Order a 75-g, 2-hour oral glucose tolerance test. (correct answer)
2. Reassure her that no further testing is needed as her GDM was diet-controlled.
3. Check a hemoglobin A1c level today.
4. Advise annual fasting plasma glucose testing starting in one year.

Explanation: Women with a history of GDM are at a significantly increased risk for developing type 2 diabetes. ACOG recommends screening for persistent diabetes or prediabetes 4 to 12 weeks postpartum. The preferred screening test is a 75-g, 2-hour oral glucose tolerance test (OGTT). Hemoglobin A1c can be falsely low in the postpartum period due to pregnancy-related increased red blood cell turnover. Delaying screening is inappropriate due to the high risk of underlying glucose intolerance.
