1. A

   Prevent external rotation

2. B

   Prevent fracture

3. C

   Prevent fat embolism

4. D

   Prevent further injury

Explanation

Listen in Hindi

• Fractures of large bones like the pelvis can release fat globules from the bone marrow into the venous circulation.
• Movement of the unstable fracture site can dislodge these fat globules, allowing them to travel to the lungs and other organs, causing Fat Embolism Syndrome (FES).
• Strict bed rest and immobilization are the primary preventive measures to keep the fracture stable and reduce the risk of this life-threatening complication.
• FES is a more specific and immediate life-threatening risk in pelvic fractures compared to the other potential complications listed.

Why Other Options Were Wrong

• Option A: Preventing external rotation is a primary concern for fractures of the femoral neck (hip fractures) to maintain alignment, not the main priority for a pelvic fracture.
• Option B: The fracture has already happened. The interventions are aimed at managing the existing injury and its complications.
• Option D: While preventing further injury is a goal of all fracture management, it is too general. Preventing fat embolism is the most specific and critical reason for strict immobilization in this clinical scenario.

Clinical Relevance

• Nursing practice connection: Prioritize focused assessment, early escalation, and real-time monitoring when managing Management of Pelvic Fractures and Prevention of Complications in acute care settings.
• Early and effective immobilization of long bone and pelvic fractures is a critical nursing priority to prevent the life-threatening complication of FES.
• Nurses must diligently monitor at-risk patients for the early signs of FES, especially within the first 24-72 hours post-injury. Key signs include new-onset confusion, restlessness, tachypnea, hypoxia, and the appearance of a petechial rash.
• Gentle handling of the patient during repositioning and care is essential to avoid dislodging fat globules from the fracture site.

How to Approach the Question

• First, identify the core clinical information: the patient has a pelvic fracture, which is a major injury to a large, marrow-filled bone.
• Next, recall the most serious and specific complications associated with fractures of large bones. These include hemorrhage, deep vein thrombosis (DVT), and fat embolism syndrome (FES).
• Analyze the intervention provided: immobilization with a splint and strict bed rest. The purpose of this is to prevent movement.
• Evaluate the options by linking the intervention (preventing movement) to the potential complications. While preventing movement helps with pain and further injury, its most critical function in this context is to prevent the mobilization of fat globules from the marrow.
• Choose the option that represents the most specific, life-threatening complication that is directly prevented by the intervention. 'Prevent fat embolism' is more specific and critical than 'Prevent further injury'.

Concept Tested & Keywords

• Concept Tested: Management of Pelvic Fractures and Prevention of Complications
• Stem keywords: pelvic fracture, Thomas splint, bed rest
• Lead-in keywords: to
• Clinical cues: The diagnosis of a pelvic fracture is a key cue, as it is a large bone with a high risk for fat embolism.
