## **Core Concept**
In a patient with suspected hemoperitoneum following a road traffic accident (RTA), the primary concern is to identify and manage the source of bleeding promptly. Hemoperitoneum refers to the accumulation of blood in the peritoneal cavity, often due to trauma. The patient's presentation with hypotension (BP 90/60) and tachycardia (pulse 140/min) suggests hypovolemic shock, a life-threatening condition requiring immediate intervention.

## **Why the Correct Answer is Right**
The correct approach in this scenario involves rapid assessment and intervention to stabilize the patient.
- **Urgent surgery (Option E)** is often required for patients with hemoperitoneum who are hemodynamically unstable, as seen in this case. The goal is to control the source of bleeding.
- **FAST (Focused Assessment with Sonography for Trauma) or USG** can quickly identify free fluid in the peritoneal cavity, suggesting hemoperitoneum, and is particularly useful in unstable patients.

## **Why Each Wrong Option is Incorrect**
- **Option A (DPL to be done):** Diagnostic Peritoneal Lavage (DPL) can be used to detect hemoperitoneum but is invasive and has largely been replaced by non-invasive imaging techniques like USG and CT scans in stable patients.
- **Option B (Liver is the MC organ to rupture):** While the liver is a common organ injured in blunt abdominal trauma, stating it as the "most common" (MC) organ to rupture might not always hold true in every context, as spleen injuries are also very common.
- **Option C (USG is better than CT Scan):** In unstable patients, **USG (or FAST)** is indeed preferred over CT scans because it's quicker and can be done simultaneously with resuscitative efforts. However, in stable patients, CT scans provide more detailed information.
- **Option D (X-ray to be taken in supine position):** While an abdominal X-ray can be part of the initial trauma workup, it's not the best initial test for suspected hemoperitoneum and does not directly assess for free fluid.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is the **ABCDE approach** in trauma patients: Airway, Breathing, Circulation, Disability, and Exposure. In a hemodynamically unstable patient with suspected abdominal trauma, the priority is to stabilize the patient (Circulation) and expedite surgical intervention if necessary.

## **Correct Answer:** E. Urgent surgery to be done
