Okay, let's tackle this question. The patient has chronic liver disease with ascites and no bleeding varices, but now presents with hematemesis and melena. I need to figure out the next step in management.

First, the core concept here is probably about upper gastrointestinal bleeding in cirrhotic patients. Since they have chronic liver disease, portal hypertension is likely a factor. But the question says there are no bleeding varices. So maybe it's a different source of bleeding. But wait, the presence of hematemesis and melena suggests an upper GI bleed. Common causes could be variceal bleeding vs. non-variceal. However, the patient doesn't have bleeding varices on history. So maybe it's a non-variceal source, like peptic ulcer or gastritis. But in cirrhosis, varices are a major concern even if not previously present. Wait, the question says no bleeding varices. So maybe the patient has acute variceal bleeding now? Or another cause.

Next step in management. For upper GI bleeding, the first step is to stabilize the patient—ABCs, IV access, blood transfusion if needed. Then, determine the source. Endoscopy is the gold standard. But if the patient has cirrhosis and ascites, varices are a big concern. However, the question states there are no bleeding varices. So maybe the initial step is to perform an urgent endoscopy to confirm whether it's variceal or non-variceal. If it's variceal, then manage with vasoconstrictors like octreotide or vasopressin, plus endoscopic band ligation. If non-variceal, then standard ulcer management with PPIs and endoscopic therapy.

But the options aren't given, so I need to think about the possible choices. The correct answer is likely urgent endoscopy. Because regardless of the cause, endoscopy is the next step to identify and treat the source. Other options might include starting vasoconstrictors, but without endoscopy, you can't confirm varices. So the next step is definitely endoscopy. The other options might be things like blood transfusion, which is important but not the first step, or starting antibiotics if there's a concern for sepsis, but that's not indicated here. Or maybe CT scan, but endoscopy is more direct.

So the core concept is upper GI bleeding in cirrhosis. The next step is urgent endoscopy to determine the source and manage accordingly. The correct answer should be endoscopy. The other options would be incorrect because they don't address the need to identify the source first.

**Core Concept**
Upper gastrointestinal (GI) bleeding in patients with chronic liver disease is most commonly due to **variceal hemorrhage** or **non-variceal causes** (e.g., peptic ulcer, gastritis). Portal hypertension from cirrhosis increases varix risk, but non-variceal bleeding must also be considered. **Endoscopy** is the gold standard to diagnose and guide treatment.

**Why the Correct Answer is Right**
The patient’s presentation (hematemesis, melena) suggests an acute upper GI bleed. Even though prior endoscopy ruled out bleeding varices, **acute variceal bleeding can develop suddenly** in decompensated cirrhosis

✓ Correct Answer: C. FFP transfusion
