Easy

Appeared in: AIIMS Delhi NO- 2019

Explanation

The device shown is a Sequential Compression Device (SCD), a form of intermittent pneumatic compression used for mechanical prophylaxis against Deep Vein Thrombosis (DVT).
It works by sequentially inflating and deflating sleeves wrapped around the legs, an action that mimics the natural muscle pump.
This mechanical squeezing enhances venous blood flow and prevents venous stasis, which is a major contributing factor to clot formation as described in Virchow's triad.
It is a standard intervention for immobile patients, particularly after surgery, to reduce the risk of DVT.

Option B: Pulmonary Embolism (PE) is a potential complication of DVT, not the primary condition the device is used to prevent. The device's direct action is on the leg veins to stop the initial clot from forming.
Option C: SCDs are used for acute DVT prophylaxis in high-risk, immobile patients. They are not the standard treatment for managing chronic varicose veins.
Option D: The device is not an analgesic and is not indicated for treating leg pain. In fact, the compression cycles can sometimes cause discomfort.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Prophylaxis of Deep Vein Thrombosis (DVT) using mechanical devices as background academic context rather than a clinical decision trigger.
SCDs are a cornerstone of DVT prevention in high-risk, immobile patients, such as post-operative, critical care, or stroke patients.
Nurses are responsible for applying the device correctly, ensuring proper fit, monitoring for complications, and educating the patient.
What if? If a patient develops signs of an active DVT (e.g., unilateral swelling, pain, redness, warmth), the SCD must be removed immediately from the affected leg, and the physician must be notified. Using the device on a leg with an existing clot could dislodge it, causing a life-threatening pulmonary embolism.

How to Approach the Question

First, identify the equipment shown in the image. The inflatable leg sleeves connected to a pump are characteristic of a Sequential Compression Device (SCD) or Intermittent Pneumatic Compression (IPC) device.
Second, recall the primary medical indication for this specific piece of equipment. Its main purpose is mechanical prophylaxis.
Third, analyze the options in the context of the device's function. The device mechanically promotes blood flow in the legs to prevent stasis.
Fourth, evaluate which option directly relates to preventing complications from blood stasis in the legs. This leads to the prevention of Deep Vein Thrombosis (DVT).
Finally, rule out the other options. PE is an indirect consequence, while varicose veins and leg pain are incorrect indications for this device.
