Which dietary instruction should the nurse include when teaching a client how to reduce episodes of Raynaud's syndrome?

• A. Avoid hot beverages.
• B. Eliminate caffeine intake.
• C. Increase calcium intake.
• D. Reduce saturated fat intake.

Answer: (B)

Raynaud's attacks happen when small arteries in the fingers and toes go into spasm, often triggered by cold or stress. Substances that promote vasoconstriction can make these episodes more frequent or severe. Caffeine is one such stimulant: it promotes constriction of blood vessels and can worsen digital color changes during an attack. So telling a client to eliminate caffeine directly targets a known trigger and can reduce how often and how intensely episodes occur. Warmth and avoiding cold exposure are helpful as well, but eliminating caffeine addresses the vasoconstriction mechanism itself. The other dietary options don’t have a direct impact on the vasospastic process.
