Name a common complication of immobility in patients.

Deep vein thrombosis (DVT) is a common complication of immobility due to the stagnation of blood flow in the lower extremities. When a patient is immobile, such as during prolonged bed rest or sitting for long periods, the lack of muscle activity impairs venous return to the heart. This slowing of blood flow can lead to the formation of blood clots in the deep veins, particularly in the legs.

Patients at increased risk for DVT include those who have undergone surgery, have certain medical conditions, or are elderly. The consequences of DVT can be severe, including the potential for a clot to dislodge and travel to the lungs, causing a pulmonary embolism, which can be life-threatening.

In contrast, while pneumonia, pressure ulcers, and constipation are also complications associated with immobility, they do not specifically reflect the immediate risk of thrombosis resulting from prolonged inactivity. Pneumonia may develop due to fluid accumulation in the lungs, while pressure ulcers occur due to unrelieved pressure on the skin, and constipation is often related to reduced mobility, diet, and fluid intake. DVT stands out as a unique concern primarily linked to the reduction of blood circulation associated with immobility.
