A client with Raynaud's disease is prescribed calcium channel blockers to manage vasospastic attacks. Which statement by the client indicates a correct understanding of the medication?

A) Exposure to cold temperatures is a well-known trigger for Raynaud's disease. In this condition, blood vessels in the extremities (usually fingers and toes) constrict excessively in response to cold temperatures or emotional stress, causing reduced blood flow and discoloration of the affected areas.

B) Consuming a diet high in vitamin C is not a trigger for Raynaud's disease. While a balanced diet is important for overall health, vitamin C intake does not directly cause Raynaud's symptoms.

C) Physical activity and exercise do not trigger Raynaud's disease. In fact, regular exercise may improve circulation and is beneficial for overall cardiovascular health.

D) Emotional stress is another common trigger for Raynaud's disease, especially in individuals with the secondary form of the condition. Emotional stress can lead to vasoconstriction and exacerbate symptoms in susceptible individuals.

A) Magnetic Resonance Imaging (MRI) is not routinely used to diagnose Raynaud's disease. It may be used in certain cases to evaluate other possible underlying conditions.

B) Doppler ultrasound is a non-invasive diagnostic test commonly used to assess blood flow in the extremities. It helps visualize blood vessels, identify areas of constriction, and confirm the diagnosis of Raynaud's disease.

C) Electrocardiogram (ECG) is a test used to assess heart function, and it is not directly related to the diagnosis of Raynaud's

disease.

D) Arteriography is an invasive procedure that involves injecting contrast dye into the arteries to visualize blood vessels. While it may be used in specific cases, it is not the primary diagnostic test for Raynaud's disease. Doppler ultrasound is preferred for initial evaluation due to its non-invasiveness.
