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

A. Restlessness: Restlessness is a common behavioral manifestation in clients with Alzheimer's disease. It can be caused by various factors, including confusion, agitation, discomfort, or unmet needs. Restlessness may manifest as pacing, fidgeting, or difficulty sitting still.

B. Aggression: Aggression, including verbal or physical aggression, is a behavioral manifestation that can occur in clients with Alzheimer's disease. Aggression may result from frustration, confusion, fear, or other underlying factors. It can present challenges for both the individual with Alzheimer's and their caregivers.

C. Depression: Depression is a mood disorder that can occur in individuals with Alzheimer's disease. Symptoms of depression may include persistent sadness, feelings of hopelessness, social withdrawal, and loss of interest in previously enjoyed activities. Depression can exacerbate cognitive decline and functional impairment in individuals with Alzheimer's.

D. Hyperactivity: Hyperactivity, characterized by excessive or restless activity, can occur in some individuals with Alzheimer's disease. Hyperactivity may be a manifestation of agitation, anxiety, or other underlying factors. It can present challenges for caregivers and may require interventions to manage.

E. Lethargy: Lethargy, or extreme fatigue and lack of energy, can also occur in individuals with Alzheimer's disease. Lethargy may result from physical and cognitive decline, medication side effects, depression, or other medical conditions. It can contribute to decreased engagement in activities and worsening of cognitive function.

A. The aortic and mitral valves are the most commonly replaced valves: This statement is accurate. The aortic and mitral valves are indeed the most commonly replaced valves in cardiac valve replacement surgeries. Aortic valve replacement is commonly performed for conditions such as aortic stenosis or regurgitation, while mitral valve replacement is often indicated for mitral regurgitation or stenosis.

B. Mitral valve insufficiency occurs during the diastolic phase of the cardiac cycle: This statement is incorrect. Mitral valve insufficiency, also known as mitral regurgitation, occurs during the systolic phase of the cardiac cycle. It involves the backflow of blood from the left ventricle into the left atrium during ventricular systole, leading to volume overload of the left atrium and potentially causing symptoms such as dyspnea and fatigue.

C. Inadequate closure of the tricuspid valve causes overload in the left ventricle: This statement is incorrect. Inadequate closure of the tricuspid valve leads to regurgitation of blood from the right ventricle back into the right atrium during ventricular systole. This condition, known as tricuspid regurgitation, causes volume overload in the right atrium and ventricle, rather than overload in the left ventricle.

D. Aortic stenosis increases right ventricular systolic pressure and decreases afterload: This statement is partially correct. Aortic stenosis indeed increases left ventricular systolic pressure and decreases afterload, not right ventricular pressure. The increased afterload on the left ventricle can lead to left ventricular hypertrophy and eventually heart failure. However, aortic stenosis does not directly affect right ventricular systolic pressure.
