A client with Raynaud's disease seeks advice on how to protect their hands and feet during cold weather. Which of the following recommendations should the nurse provide to the client?

A) Exposure to cold temperatures is not recommended for clients with Raynaud's disease as it can trigger symptoms and worsen the condition.

B) Limiting fluid intake does not directly impact Raynaud's disease. Adequate hydration is essential for overall health, but it does not affect the frequency of Raynaud's episodes.

C) Engaging in regular physical exercise and activity is beneficial for individuals with Raynaud's disease. Exercise improves circulation and helps maintain vascular health, which may reduce the severity and frequency of Raynaud's symptoms.

D) Increasing caffeine consumption is not a recommended strategy for managing Raynaud's disease. While caffeine may have mild vasoconstrictive effects, it is not a significant factor in managing the condition.

A) Elevated blood pressure readings are not directly related to Raynaud's disease. While the condition can affect blood flow to the extremities, it does not cause consistently elevated blood pressure.

B) Hyperactive reflexes in the extremities are not typically associated with Raynaud's disease. These reflexes may be indicative of other neurological issues.

C) Skin thickening and tightening on the fingers are characteristic features of systemic sclerosis, which is a condition often associated with secondary Raynaud's disease. The combination of Raynaud's symptoms with skin changes may raise suspicion for an underlying autoimmune disorder.

D) Abnormal blood clotting tests are not specific to Raynaud's disease. Raynaud's primarily involves vasospasm and decreased blood flow, rather than abnormal clotting.
