Which of the following describes a general health benefit of repositioning for body systems?

• A. Promotes efficient function of the patient's body systems
• B. Only improves comfort with no systemic effects
• C. Causes no changes in respiratory mechanics
• D. Is harmful to cardiovascular function when done correctly

Answer: (C)

Repositioning influences multiple body systems by changing the mechanical conditions they rely on, which helps them work more efficiently. When a patient is moved, the chest can expand more fully, improving ventilation and gas exchange and making coughing more effective. This boosts ventilation–perfusion matching and helps prevent atelectasis and infection. At the same time, changing position reduces venous stasis, supports venous return, and can lessen edema, aiding cardiovascular function. It also relieves pressure on tissues, supporting lymphatic flow and organ function. So the broad health benefit is that repositioning promotes efficient function of the body’s systems overall, not just comfort. The ideas that it has no systemic effects or that it harms cardiovascular function when done correctly aren’t accurate.
