A nurse is teaching a client with primary osteoarthritis about strategies to reduce joint pain. Which intervention should the nurse emphasize as most effective?

A. The patient stops having diarrhea: Misoprostol can actually cause diarrhea as a common adverse effect. Cessation of diarrhea does not indicate therapeutic effectiveness and may reflect other factors.

B. The patient reports reduced heartburn and indigestion: Misoprostol is a prostaglandin analog that protects the gastric mucosa and reduces NSAID-induced gastrointestinal irritation. Relief of dyspepsia, heartburn, or epigastric discomfort indicates that the medication is effectively preventing or treating NSAID-related gastric damage.

C. The patient reports a decrease in joint pain: Misoprostol does not have analgesic properties and does not relieve osteoarthritis pain. NSAIDs are responsible for managing joint inflammation and pain, not misoprostol.

D. The patient's blood pressure improves: Misoprostol has no significant effect on blood pressure. Cardiovascular parameters are unrelated to the therapeutic goal of protecting the gastric mucosa during long-term NSAID therapy.

A. Follow a high-sodium diet to prevent fluid loss: Clients with SLE are at risk for hypertension and renal involvement, including lupus nephritis. Excess sodium can worsen fluid retention, edema, and blood pressure control. Sodium restriction is often recommended rather than increased intake.

B. Avoid calcium and vitamin D supplements to prevent kidney stones: Clients with SLE are at increased risk for osteoporosis due to chronic inflammation and long-term corticosteroid use. Calcium and vitamin D are commonly encouraged to support bone health. Avoidance is not routinely indicated unless specific contraindications exist.

C. Eat a low-fat, high-fiber diet with fruits, vegetables, and whole grains: SLE is associated with chronic inflammation and increased cardiovascular risk. A diet rich in fiber, antioxidants, and healthy fats supports cardiovascular health and helps manage dyslipidemia. This dietary pattern also supports immune function and overall metabolic health.

D. Increase red meat intake to improve anemia: While anemia may occur in SLE, increasing red meat intake is not routinely recommended due to its saturated fat content. Anemia management depends on the underlying cause, such as chronic disease or iron deficiency. Dietary changes should be targeted rather than generalized.
