The purpose of anti-embolism stocking is to?

Appeared in: Daman & Diu Staff Nurse - 2018

Explanation

The main function of anti-embolism stockings is to apply graduated compression to the legs.
This pressure is highest at the ankle and gradually decreases up the leg.
This mechanism enhances venous return, pushing blood from superficial veins into deep veins and back towards the heart.
By preventing blood from pooling (venous stasis), the stockings reduce the hydrostatic pressure that causes fluid to leak into tissues, thus reducing or preventing edema (swelling).
This action also helps prevent the formation of deep vein thrombosis (DVT).

Option A: While the fabric of the stockings may provide some warmth, this is merely a side effect and not their primary therapeutic purpose. Their function is mechanical compression, not temperature regulation.
Option B: Decreasing arterial circulation is dangerous and can lead to tissue ischemia. Anti-embolism stockings are specifically contraindicated in patients with significant peripheral arterial disease for this reason.
Option D: This is the opposite of the stocking's intended function. The entire purpose is to increase, or promote, the flow of venous blood from the legs back to the heart.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Purpose and mechanism of anti-embolism stockings as background academic context rather than a clinical decision trigger.
Anti-embolism stockings are a cornerstone of DVT prophylaxis in immobile, post-operative, and high-risk medical patients.
Nurses must perform accurate leg measurements to ensure the correct size is chosen. Stockings that are too tight can impair circulation (acting as a tourniquet), while those that are too loose are ineffective.
Regular neurovascular assessment of the distal extremities (toes) is critical to ensure arterial flow is not compromised. This includes checking color, temperature, sensation, and capillary refill.

How to Approach the Question

First, identify the core concept of the question, which is the purpose of 'anti-embolism stockings'.
Recall the primary mechanism of these stockings: they apply external pressure to the legs.
Think about the circulatory system in the legs. The goal is to help blood return to the heart (venous return) and prevent it from pooling.
Evaluate each option based on this physiological principle.
Option A (warmth) is a side effect, not a purpose.
Option B (decrease arterial flow) is a dangerous complication.
