**Core Concept**
The management of a patient with a splenic injury involves balancing the need to control bleeding with the risk of exacerbating the injury, particularly in the setting of potential splenic conservation. The decision to proceed with splenectomy or attempt to preserve the spleen depends on the severity of the injury and the patient's hemodynamic stability.

**Why the Correct Answer is Right**
In this case, the patient has been resuscitated and stabilized, with a pulse rate of 84/minute and blood pressure of 120/70 mmHg. This suggests that the initial bleeding has been controlled, and the patient is now in a stable condition. The next step would be to perform a diagnostic peritoneal lavage (DPL) or an abdominal CT scan to assess the extent of the splenic injury and determine the best course of management. If the injury is deemed non-viable or the patient is unstable, splenectomy may be necessary. However, if the injury is minor and the patient is stable, splenic preservation may be attempted.

**Why Each Wrong Option is Incorrect**
**Option A:**
This option is incorrect because immediate splenectomy is not the best initial management strategy, especially since the patient is hemodynamically stable.

**Option B:**
This option is incorrect because it does not address the need for further diagnostic evaluation to determine the extent of the splenic injury.

**Option C:**
This option is incorrect because it does not provide a clear plan for managing the patient's potential splenic injury.

**Clinical Pearl / High-Yield Fact**
In patients with splenic injury, the goal is to preserve the spleen if possible, as it plays a crucial role in immune function. Splenectomy should be reserved for cases where the spleen is non-viable or the patient is unstable.

**Correct Answer:** D.

✓ Correct Answer: D. Continuation of conservative treatment under close monitoring system and subsequent surgery if fuher indicated
