A woman has recently been diagnosed with Raynaud’s disease.

What important information should the nurse provide to this patient?

Choice A rationale
Smoking cigarettes can exacerbate the symptoms of Raynaud’s disease by causing further constriction of the blood vessels. Therefore, a patient who continues to smoke cigarettes may need further education about the management of Raynaud’s disease.
Choice B rationale
Eating bananas twice a day is not typically a concern for patients with Raynaud’s disease.
Choice C rationale
Wearing mittens outside, especially in cold weather, is a recommended strategy for managing Raynaud’s disease. It can help to prevent episodes of Raynaud’s by keeping the hands warm and reducing exposure to cold temperatures.
Choice D rationale
Taking calcium channel blockers is a common treatment for Raynaud’s disease. These medications help to relax and open up the small blood vessels in the hands and feet, reducing the severity and frequency of Raynaud’s episodes.

Choice A rationale
Prolonged PR intervals occur with first-degree AV block, not typically with pericarditis.
Choice B rationale
Clubbing of the fingers is a loss of the normal angle between the base of the nail and the skin. This finding can be found in endocarditis, congenital defects, and/or prolonged oxygen deficiency. It is not a typical manifestation of pericarditis.
Choice C rationale
Widened pulse pressure occurs with valvular heart disease, not typically with pericarditis.
Choice D rationale
Pulsus paradoxus is a sign of cardiac tamponade, a serious complication of pericarditis. As the compression of the heart increases, decreased left atrial filling decreases cardiac output.
