A nurse is completing a focused assessment addressing a client's immune function. What should the nurse prioritize in the physical assessment?

Choice A:
Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive difficulties. Activity intolerance is a common symptom, resulting in patients experiencing increased fatigue, pain, and decreased function with exertion.
A program of regular mild to moderate exercise is considered the cornerstone of management for fibromyalgia. Exercise improves physical fitness, reduces pain intensity, and enhances sleep quality. It also decreases fatigue and depression, and improves overall well-being and quality of life. The key is to start with low-impact activities, gradually increase intensity and duration over time, and listen to the body's signals to avoid overexertion.
Here's how exercise benefits patients with fibromyalgia:
Pain reduction: Exercise releases endorphins, natural pain-relieving chemicals in the brain. It also strengthens muscles and improves joint flexibility, leading to decreased pain intensity and frequency.
Improved physical fitness: Regular exercise increases cardiovascular health, muscle strength, and endurance, allowing patients to tolerate activity better and perform daily tasks with less fatigue.
Enhanced sleep quality: Exercise can regulate sleep patterns, promoting deeper sleep and reducing nighttime pain, leading to improved energy levels and mood throughout the day.
Reduced fatigue and depression: Exercise triggers the release of mood-boosting neurotransmitters, like serotonin and dopamine, which can help alleviate symptoms of depression and fatigue commonly associated with fibromyalgia.
Improved overall well-being: Regular physical activity enhances self-efficacy, reduces stress, and promotes social interaction, contributing to a better quality of life for patients with fibromyalgia.
Therefore, a program of regular mild to moderate exercise is the most effective recommendation for patients with fibromyalgia to address activity intolerance and improve their overall well-being.
Rationale for other choices:

Choice B: While daily meditation and guided imagery can be helpful for managing stress and improving sleep in fibromyalgia, they are not as effective as exercise in directly addressing activity intolerance and improving physical fitness and function.

Choice C: Referral to physical therapy for an assistive device may be necessary in some cases with severe limitations, but it is not the first-line intervention for addressing activity intolerance in most patients with fibromyalgia. Exercise should be the initial focus, with assistive devices considered later if needed.

Choice D: NSAID medications can offer temporary pain relief, but they do not address the underlying cause of activity intolerance in fibromyalgia and can have side effects like gastritis and kidney problems. NSAIDs should be used cautiously and only as a complementary therapy alongside exercise in managing fibromyalgia symptoms.
Remember, a tailored exercise program, starting with low-impact activities and gradually increasing intensity, is the key to managing activity intolerance and improving function in patients with fibromyalgia.

Choice A rationale:
Serum creatinine is a waste product that is produced by muscle metabolism and is normally excreted by the kidneys.
When kidney function is impaired, creatinine levels in the blood increase, making it a sensitive and specific indicator of renal function.
It is considered one of the most reliable markers for assessing kidney function and is routinely used to screen for and monitor kidney disease.

Choice B rationale:
Serum sodium is an electrolyte that is regulated by the kidneys, but it is not a direct measure of renal function. Sodium levels can be affected by various factors, including fluid intake, medications, and hormonal imbalances.
While abnormal sodium levels can sometimes be a sign of kidney dysfunction, they can also occur due to other conditions, making it less specific as an indicator of renal function.
Choice C rationale:

Blood urea nitrogen (BUN) is another waste product that is produced by the breakdown of proteins and is normally excreted by the kidneys.
However, BUN levels can be influenced by factors other than kidney function, such as dietary protein intake, dehydration, and gastrointestinal bleeding.
This makes BUN less specific than serum creatinine as a marker of renal function.

Choice D rationale:
Urine-specific gravity measures the concentration of solutes in urine, which can provide some information about kidney function.
However, it is not as sensitive or specific as serum creatinine.
Urine-specific gravity can be affected by factors such as fluid intake and hydration status, which can make it less reliable as an indicator of renal function.
