Certified Wound Ostomy Nurse (CWON) Practice Test

Which of the following is a recommended dietary approach for patients with calciphylaxis?

1. Increase calcium intake

2. Maintain a low calcium and phosphate diet

3. Include high vitamin D foods

4. Avoid protein-rich foods

The correct answer is: Maintain a low calcium and phosphate diet

Maintaining a low calcium and phosphate diet is a crucial dietary approach for patients with calciphylaxis, a condition characterized by vascular calcification and skin necrosis. In calciphylaxis, there is often an imbalance of calcium and phosphate levels, which can exacerbate the disease process. High levels of calcium and phosphate can lead to the formation of calcium deposits in the small blood vessels, causing skin ulcerations and potential infection. By limiting dietary intake of calcium and phosphate, patients can help manage their serum levels and potentially reduce the risk of further complications associated with calciphylaxis. This dietary restriction is vital, especially considering that patients with this condition often have underlying renal disease and issues with mineral metabolism. The other dietary approaches listed are not recommended because increasing calcium intake or including high vitamin D foods may lead to elevated calcium levels, which could worsen the symptoms of calciphylaxis. Avoiding protein-rich foods is also not a standard part of the dietary management for this condition, as protein is essential for overall health and healing. Therefore, keeping calcium and phosphate intake low is the most beneficial approach for patients with calciphylaxis.
