Okay, let's tackle this question. The patient is a 23-year-old primigravida who delivered two days ago. She's having bloody discharge with a sweetish odor. The pelvic exam shows a soft, non-tender uterus. Vital signs are stable. WBC is elevated with granulocytes. So, the main concern here is postpartum hemorrhage or maybe an infection.

First, the symptoms: bloody discharge with a sweet odor. That makes me think of something like lochia. Normally, lochia rubra is bright red and occurs in the first few days postpartum. But the sweet odor could be a sign of infection. However, the patient doesn't have other signs like fever or uterine tenderness. The WBC is slightly elevated but not drastically.

Wait, the placenta was delivered spontaneously, so retained placenta is less likely. The uterus is soft but non-tender. A soft uterus could mean uterine atony, which is a common cause of postpartum hemorrhage. But the patient isn't having active bleeding or significant blood loss. She just has a bloody discharge.

The sweet odor might be a clue. Sometimes, lochia can have a mild odor, but a sweetish one might not be typical. Could there be a retained placental tissue causing an infection? But again, there's no fever or tenderness. Alternatively, maybe it's just normal lochia. The key here is to assess for the cause of the bleeding.

The options aren't given, but the correct answer is probably related to evaluating for retained placental tissue or infection. However, since the uterus is soft and non-tender, maybe the next step is to monitor or perform an ultrasound. But without the options, it's hard to say. Wait, the user mentioned the correct answer is C. Let me check the possible steps again.

Wait, the user's correct answer is missing. But given the scenario, the most appropriate step would be to perform a pelvic ultrasound to check for retained placental tissue or hematoma. Alternatively, maybe a speculum exam to check for lacerations. But since the placenta was delivered, maybe it's lochia. The sweet odor might not be concerning if it's just normal lochia. The WBC count is slightly elevated but not indicative of infection. So perhaps the answer is to monitor, but the presence of the sweet odor might prompt further investigation.

Alternatively, maybe it's a case of subinvolution of the uterus. But the uterus is soft, which can happen if there's retained products. The next step would be an ultrasound to confirm. So the correct answer would be to do an ultrasound. The other options might be antibiotics, which are incorrect if there's no infection signs. So the correct step is imaging.

**Core Concept**
Postpartum vaginal bleeding with abnormal odor requires differentiation between normal lochia, retained placental tissue, or infection. Key clinical signs include uterine consistency, presence of fever, and leukocytosis.

**Why the Correct Answer is Right**
The patient’s symptoms—sweetish odor, soft uterus, and mild leukocytosis—suggest **retained placental tissue** causing localized necrosis. Normal lochia has a mild, non-foul odor. A soft, boggy uterus would indicate atony, but this patient’s uterus is described as soft and
