During patient care, every 15 minutes shifting weight helps to:

Shifting weight every 15 minutes during patient care is primarily designed to reduce the risk of skin breakdown, particularly in individuals who are immobilized or have limited mobility. Prolonged pressure on specific areas of the skin can compromise blood flow, leading to ischemia and eventually pressure ulcers, also known as bedsores. By regularly redistributing weight, the skin and underlying tissues are given a chance to recover and receive adequate blood supply, thus maintaining skin integrity and overall health.

The other options do not align with the primary benefits of this practice. For instance, while enhancing muscle growth or promoting sleep are important aspects of patient care, they are not directly associated with the function of shifting weight in this context. Additionally, increasing blood pressure is not a desired outcome of this practice, as the aim is to maintain comfort and prevent complications rather than exert stress on the cardiovascular system.
