A nurse is providing education to a client newly diagnosed with Raynaud's disease. Which statement made by the client indicates a correct understanding of the condition?

A) Beta-blockers are not commonly prescribed for Raynaud's disease. In fact, they may worsen the condition by causing vasoconstriction.

B) Antihistamines are not used to manage Raynaud's disease. They primarily target histamine receptors and are not effective in improving blood flow.

C) Oral corticosteroids are not typically used to manage Raynaud's disease. They have anti-inflammatory effects but are not effective in treating the underlying vascular dysfunction of Raynaud's.

D) Calcium channel blockers, such as nifedipine or amlodipine, are commonly prescribed for Raynaud's disease. These medications help relax and dilate blood vessels, improving blood flow to the extremities and reducing the frequency and severity of Raynaud's episodes.

A) Hypertension and heart disease are not typically associated with Raynaud's disease. However, it's essential to monitor these conditions as they may have an impact on the overall management of the client's health.

B) Diabetes mellitus and obesity are not directly linked to Raynaud's disease. However, maintaining a healthy lifestyle is important for overall well-being, including managing Raynaud's symptoms.

C) Systemic lupus erythematosus and scleroderma are two autoimmune disorders that are often associated with secondary Raynaud's disease. In these conditions, the immune system attacks the body's tissues, leading to blood vessel abnormalities and an increased risk of Raynaud's symptoms.

D) Seasonal allergies and asthma are unrelated to the development or exacerbation of Raynaud's disease. These conditions primarily involve the respiratory system, not the vascular system.
