A nurse is teaching a client who has pericarditis. Which of the following statements should the nurse include in the client teaching to explain the cause of pericarditis?

A. "Medications for Alzheimer's disease will help to increase my energy levels": This statement is not accurate. Medications for Alzheimer's disease, such as cholinesterase inhibitors (e.g., donepezil, rivastigmine) and memantine, are not intended to increase energy levels. Their primary goal is to improve cognitive function and help manage symptoms associated with Alzheimer's disease, but they do not directly affect energy levels.

B. "Medications for Alzheimer's disease will help slow the progression of my disease": This statement is correct. Medications used to treat Alzheimer's disease, such as cholinesterase inhibitors and memantine, are aimed at slowing the progression of cognitive decline and managing symptoms associated with the disease. While these medications cannot cure Alzheimer's disease, they can help improve cognitive function and quality of life for some individuals.

C. "Medications for Alzheimer's disease will help me remember what I forgot": This statement oversimplifies the effects of Alzheimer's medications. While these medications may help improve memory and cognition to some extent, they are not capable of restoring lost memories or reversing the effects of significant memory impairment caused by Alzheimer's disease.

D. "Medications for Alzheimer's disease will cure the disease": This statement is incorrect. Currently, there is no cure for Alzheimer's disease. Medications used to treat Alzheimer's, such as cholinesterase inhibitors and memantine, can help manage symptoms and slow disease progression, but they do not cure the underlying condition.

A. "Blood flow is altered and causes blood to pool in the legs." This statement inaccurately describes venous insufficiency rather than peripheral arterial disease (PAD). In PAD, blood flow is reduced or obstructed due to atherosclerosis, leading to inadequate oxygen supply to tissues rather than pooling of blood in the legs.

B. "Blood flow is altered due to atherosclerosis affecting the tissues' ability to receive oxygen-rich blood." This statement correctly explains the underlying pathology of peripheral arterial disease (PAD). Atherosclerosis, characterized by the buildup of plaque in the arteries, narrows or blocks blood flow, impairing the delivery of oxygen-rich blood to the tissues. This can result in symptoms such as pain, cramping, and tissue damage, especially during activity when oxygen demand increases.

C. "Blood flow is altered due to incompetent valves causing increased venous pressure." This statement describes venous insufficiency rather than PAD. In venous insufficiency, faulty valves in the veins result in increased venous pressure, leading to symptoms such as swelling, heaviness, and varicose veins, but it does not involve arterial obstruction as seen in PAD.

D. "Blood flow is altered due to excessive stretching of the ventricles impairing the heart to contract." This statement describes a condition related to the heart's function rather than peripheral arterial disease. Excessive stretching of the ventricles may occur in conditions such as heart failure, but it does not directly affect blood flow in the peripheral arteries as seen in PAD.
