**Core Concept**
The patient in this scenario is experiencing hemorrhagic shock due to splenic and liver lacerations as well as an unstable pelvic fracture, which requires a damage control resuscitation approach. This involves addressing the underlying cause of bleeding and hypotension through surgical intervention, rather than simply administering fluids.

**Why the Correct Answer is Right**
The correct answer involves a combination of surgical intervention and the use of blood products to address the underlying cause of bleeding. The patient's hypotension and tachycardia indicate inadequate perfusion of vital organs, and the administration of 2 L of crystalloid has not been sufficient to correct this. The use of blood products, such as packed red blood cells, fresh frozen plasma, and platelets, is essential to restore blood volume and prevent further coagulopathy. Additionally, the patient's unstable pelvic fracture requires external fixation to stabilize the pelvis and reduce bleeding.

**Why Each Wrong Option is Incorrect**
**Option A:** Administering more crystalloid would not address the underlying cause of bleeding and would likely lead to further dilutional coagulopathy.
**Option B:** Focusing solely on fluid resuscitation would not address the need for surgical intervention to control bleeding.
**Option C:** Delaying surgical intervention would allow further bleeding and potential organ failure, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
In trauma patients with hemorrhagic shock, the goal of resuscitation should be to address the underlying cause of bleeding, rather than simply administering fluids. This requires a damage control resuscitation approach that involves a combination of surgical intervention and the use of blood products.

**Correct Answer:** C.

✓ Correct Answer: D. Infusion of packed red blood cells and early administration of fresh-frozen plasma and platelets prior to return of laboratory values
