The nurse is caring for a client with a history of chronic kidney disease. Which dietary restriction should the nurse emphasize?

Choice A reason: Limiting purine-rich foods (e.g., organ meats, shellfish) reduces uric acid production, preventing gout flares. Purines metabolize into uric acid, which forms joint crystals in gout. This dietary restriction is critical to manage symptoms and prevent painful exacerbations effectively.

Choice B reason: Increasing dairy may reduce gout risk by lowering uric acid, but it is secondary to purine restriction. Limiting purines directly decreases uric acid synthesis, addressing the primary cause of gout flares, making it the priority dietary recommendation.

Choice C reason: Restricting carbohydrates is irrelevant to gout, which results from uric acid accumulation. Purine-rich foods are the primary dietary trigger, as they increase uric acid. Limiting purines is the priority, as it directly prevents crystal formation and gout exacerbations.

Choice D reason: Encouraging red meat, high in purines, worsens gout by increasing uric acid production. Limiting purine-rich foods is critical, as it reduces uric acid and joint crystal formation, making red meat consumption counterproductive to effective gout management.

Choice A reason: Obtaining an arterial blood gas assesses oxygenation and acid-base status, useful in COPD management, but is not required before postural drainage. This invasive procedure is unnecessary for routine drainage, which mobilizes secretions. Explaining positions prepares the client, enhancing cooperation and effectiveness.

Choice B reason: Performing drainage after meals risks aspiration or vomiting, as a full stomach increases intra-abdominal pressure in COPD patients. Postural drainage is most effective when performed on an empty stomach, making this approach incorrect. Patient education on positioning is the priority.

Choice C reason: Shallow, fast breathing is counterproductive in COPD, as it reduces tidal volume and worsens hypercapnia. Postural drainage requires slow, deep breaths to mobilize secretions and improve ventilation. Explaining positions ensures proper technique, making this breathing instruction incorrect.

Choice D reason: Explaining that the client may be placed in five positions (e.g., prone, supine, lateral) prepares them for postural drainage, which uses gravity to mobilize lung secretions in COPD. This education enhances compliance and effectiveness, as proper positioning is critical for therapeutic success, making it the correct approach.
