A nurse is teaching a client who has fibromyalgia about self-care strategies for managing the disorder. Which of the following information should the nurse include in the teaching?

Choice A rationale Aerobic activities like jogging or running involve repetitive high-impact forces that significantly stress the musculoskeletal system and joints. In fibromyalgia, the central nervous system processes pain signals abnormally, leading to widespread mechanical hypersensitivity. High-impact exercise can trigger severe pain flares by overstimulating these sensitized pathways. Instead, low-impact activities like swimming or walking are recommended to maintain mobility without exacerbating the chronic pain cycle typical of this disorder. Choice B rationale Complete cessation of movement during a flare-up can lead to increased muscle stiffness and further functional decline. While the intensity should be adjusted based on pain levels, total inactivity often results in a vicious cycle of deconditioning and heightened pain perception. Maintaining gentle range-of-motion exercises or light stretching helps preserve joint flexibility and prevents the physical complications associated with prolonged immobility, which is crucial for managing the multifaceted symptoms of fibromyalgia over time. Choice C rationale Sleep disturbances are a core feature of fibromyalgia, often involving a lack of restorative deep sleep, which correlates with increased pain sensitivity. Establishing a consistent sleep-wake cycle helps regulate the circadian rhythm and supports the production of growth hormones necessary for muscle repair. Proper sleep hygiene reduces fatigue and improves cognitive function, directly addressing the underlying neurological dysregulation. A regular pattern is a fundamental self-care strategy to improve the overall quality of life. Choice D rationale While calcium is essential for maintaining bone density and facilitating muscle contraction, there is no direct scientific evidence linking increased calcium intake to the management of fibromyalgia symptoms. Fibromyalgia is primarily characterized by central pain processing issues rather than nutritional deficiencies in calcium. While a balanced diet is important for general health, focusing specifically on calcium does not address the neuropathic or myofascial pain mechanisms that define this chronic condition for most patients.
