Which of the following correctly describes the effects of immobility?

Immobility significantly impacts the body in various ways, and one of the most critical concerns is the increased risk of pressure sores, also known as pressure ulcers or decubitus ulcers. When an individual is unable to change positions or move due to immobility, prolonged pressure on specific areas of the skin can reduce blood flow to those areas. This inadequate blood supply can lead to tissue damage, resulting in pressure sores.

The development of pressure sores is particularly common over bony prominences such as the heels, sacrum, and hips. The extended pressure on these areas can cause the skin and underlying tissues to break down, making the person vulnerable to infection and other complications. Thus, understanding the consequences of immobility emphasizes the need for regular repositioning, skin assessments, and implementing preventive measures in caregiving practices to reduce this risk.

In contrast, the other options suggest positive or protective effects that are not associated with immobility. For instance, immobility does not contribute to improved circulation, skin protection, or strengthened muscles; rather, it leads to detrimental outcomes in these areas. Therefore, recognizing the increased risk of pressure sores as a primary effect of immobility is crucial for effective patient care and nursing practice.
