Which of the following is a common complication of immobility?

Thromboembolism is a significant complication that can arise from immobility due to the decreased blood flow and stasis associated with being inactive for extended periods. When a person is immobile, blood circulation slows, particularly in the lower extremities, which can lead to the formation of blood clots in the deep veins of the legs (deep vein thrombosis, or DVT). If these clots dislodge, they can travel to the lungs, resulting in a pulmonary embolism, a serious and potentially life-threatening condition.

This risk is particularly pronounced in patients who are bedridden or who have limited movement due to medical conditions, surgeries, or prolonged hospitalization. Therefore, healthcare providers must implement measures such as leg exercises, frequent repositioning, and possibly anticoagulation therapy in at-risk patients to prevent thromboembolism.

In contrast, the other options do not relate to immobility in the same way. Hyperactivity would not be a complication associated with immobility, as a lack of movement typically results in decreased activity levels. Skin thickening is generally not a direct consequence of immobility; instead, immobility often leads to skin breakdown rather than thickening. Regular weight gain can occur in immobile patients,
