Which nursing intervention is priority for preventing complications of rheumatic heart disease?

Choice A reason: Avoiding cold temperatures prevents vasospasm in Buerger’s disease but is secondary to tobacco cessation, the primary driver of disease progression. Cold exacerbates symptoms, but smoking causes the underlying inflammation and thrombosis, making this a less critical initial focus for teaching.

Choice B reason: Meticulous hygiene prevents infection in ischemic tissues but does not address the primary cause of Buerger’s disease progression, which is tobacco use. Hygiene is supportive but secondary, making this an incorrect initial focus compared to eliminating the disease’s main trigger.

Choice C reason: A low-saturated fat diet reduces atherosclerosis risk but is not the primary intervention for Buerger’s disease, which is driven by tobacco-induced inflammation and thrombosis. While beneficial for cardiovascular health, it is secondary to smoking cessation, making this an incorrect initial teaching focus.

Choice D reason: Abstaining from tobacco is the primary intervention for Buerger’s disease, as smoking causes inflammatory thrombosis, leading to vessel occlusion and ischemia. Cessation halts disease progression, reducing pain and tissue damage, making this the nurse’s initial focus to effectively manage and prevent worsening of the condition.

Choice A reason: Kawasaki disease primarily causes vasculitis, not muscle injury. It affects blood vessels, particularly coronary arteries, due to an immune response, not muscles. This statement is incorrect, as it misidentifies the target of the immune response, indicating a need for further education on the disease’s effects.

Choice B reason: Kawasaki disease is an immune-mediated vasculitis that can weaken coronary arteries, risking aneurysms and cardiac complications. This statement accurately reflects the disease’s pathophysiology, showing caregiver understanding of the education provided, making it the correct choice for the nurse to recognize.

Choice C reason: Kawasaki disease does not only affect the liver; it causes systemic vasculitis, particularly impacting coronary arteries. Liver involvement is rare and not primary. This statement is incorrect, as it misrepresents the disease’s scope, requiring further teaching to clarify its cardiovascular effects.

Choice D reason: Kawasaki disease involves systemic vasculitis, not just skin. While skin rashes occur, the primary concern is vascular, especially coronary, damage. This statement is incorrect, as it limits the disease to skin, indicating a need for education on its broader, particularly cardiac, implications.
