A patient with Raynaud's disease is admitted to the hospital with cyanotic fingers and extreme pain. The nurse understands that these symptoms are associated with

ingestion of caffeinated beverages

Explanation

• Raynaud's disease is characterized by intermittent vasospastic attacks. These acute attacks are often precipitated by stress, cold temperatures, caffeine, or smoking.

• Incorrect: Prolonged bed rest is not associated with Raynaud's disease.

• Incorrect: Alcohol and extreme heat cause vasodilation, not vasospasm.
