Question

A patient suffering from severe burns experiences extensive plasma loss. Which of the following blood components would be MOST crucial to administer immediately to stabilize their circulatory volume?

BALASOURY · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Fluid balance and circulatory shock in burn victims.
 **Related Topics**: Blood components, plasma expanders, hypovolemic shock, burn management.
 **Prerequisites**: Understanding of blood composition, the role of plasma in maintaining blood volume, and the physiological consequences of severe burns.
## SOLUTION PATHWAY
**Given Information**:
  A patient with severe burns has experienced significant plasma loss.
  The goal is to stabilize circulatory volume immediately.
**Method & Steps**:
 1. Identify the immediate cause of circulatory instability.
  Reasoning: Severe burns cause significant fluid loss, primarily plasma, leading to hypovolemic shock (decreased blood volume). This reduces blood pressure and impairs tissue perfusion.
  Formula/Rule: None directly applicable, this is a physiological understanding question.
 2. Determine the most effective way to restore circulatory volume quickly.
  Working: Packed red blood cells primarily increase oxygen-carrying capacity; platelets aid in clotting; whole blood contains all components but is less readily available and may cause complications. Plasma expanders directly increase blood volume without the complexities of whole blood.
  Key Point:  Speed is crucial in treating hypovolemic shock. Plasma expanders are the fastest way to restore circulating volume.
 3. Select the most appropriate blood component.
  Result: Plasma expanders like dextran are the most crucial component to administer immediately to restore circulatory volume in a burn patient.
  Verification: Plasma expanders are specifically designed to rapidly increase blood volume, addressing the immediate life-threatening hypovolemia caused by plasma loss in burn patients.
 ## OPTION ANALYSIS
A :x: Packed red blood cells primarily address oxygen-carrying capacity, not immediate volume restoration.
B :x: Platelet concentrate addresses clotting issues, not the immediate volume deficit.
C ✓: Plasma expanders like dextran directly and rapidly increase blood volume, stabilizing circulatory shock.
D :x: Whole blood is a more complex option and takes longer to administer, less ideal for immediate volume restoration in severe cases.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Choosing whole blood due to its comprehensive nature: Whole blood is not always readily available and may cause complications; speed is crucial.
  2.Focusing on oxygen-carrying capacity: While important, maintaining adequate circulatory volume is the priority in acute hypovolemic shock.
 **Quick Tips**:
  1.Remember that plasma loss in burns leads to hypovolemic shock, requiring rapid volume replacement.
  2.Plasma expanders are the quickest solution for restoring volume.
