What is a common risk for adults due to prolonged immobility?

• A. Physiological systems are at risk.
• B. Increased energy levels.
• C. Enhanced social activity.
• D. No health impact.

Answer: (A)

Prolonged immobility disrupts normal body function across many systems, making physiological systems across the body at risk. When a person remains in bed or sedentary for extended periods, blood flow in the legs slows, increasing the likelihood of venous thromboembolism. The lungs don’t inflate as fully, which can lead to atelectasis and a higher risk of pneumonia, reducing oxygenation. Muscles lose mass and strength quickly (atrophy), and bones lose mineral density, raising the chances of weakness and fractures. Continuous pressure from lying can cause skin breakdown and pressure ulcers. The digestive and urinary tracts slow down, leading to constipation and urinary retention, which can cause discomfort or infection. Metabolic changes and overall deconditioning can occur as well, compounding fatigue and reducing resilience.

Understanding these risks highlights why maintaining movement and promoting activity is essential: regular turning and repositioning, range-of-motion exercises, early mobilization as tolerated, and interventions like incentive spirometry, deep breathing, adequate hydration, proper nutrition, and diligent skin care all help mitigate these physiological dangers. In contrast, the other options describe outcomes that do not align with the effects of immobility, since energy, social activity, and health status are typically not increased or unchanged with prolonged immobility.
