A nurse is teaching a client who has peripheral venous disease about management of symptoms. Which of the following client statements indicates to the nurse an understanding of the teaching?

A. Septal myectomy: Septal myectomy is a surgical procedure primarily used to treat hypertrophic cardiomyopathy (HCM), not atrial fibrillation. It involves removing a portion of the thickened septal wall in the heart to improve blood flow.

B. Synchronized electrical cardioversion: Synchronized electrical cardioversion is a procedure used to convert abnormal heart rhythms, such as atrial fibrillation, back to normal sinus rhythm. It involves delivering a synchronized electrical shock to the heart at a specific point in the cardiac cycle to restore normal rhythm.

C. Pericardiocentesis: Pericardiocentesis is a procedure used to remove fluid from the pericardial sac surrounding the heart. It is typically performed to relieve cardiac tamponade or to investigate the cause of pericardial effusion.

D. Pericardial window: A pericardial window is a surgical procedure performed to create a permanent opening in the pericardium, the sac surrounding the heart. It is usually done to drain fluid or air from the pericardial space, often in cases of recurrent pericardial effusion or cardiac tamponade.

A. Relocation stress syndrome: Relocation stress syndrome refers to the physical and psychological symptoms experienced by individuals when they are moved from one environment to another, such as transitioning to a new residence or healthcare facility. While relocation stress syndrome can cause agitation and confusion in individuals with Alzheimer's disease, the scenario provided does not indicate a recent relocation.

B. Wandering: Wandering is a common behavior observed in individuals with dementia, where they aimlessly roam or wander in their environment. While wandering may be associated with agitation and restlessness, the scenario does not describe the client physically moving around or attempting to leave their home.

C. Sundowning: Sundowning refers to a phenomenon commonly observed in individuals with Alzheimer's disease or other forms of dementia, where they experience increased agitation, confusion, and restlessness in the late afternoon or early evening hours. Sundowning behaviors can include pacing, agitation, anxiety, irritability, confusion, and difficulty sleeping. The exact cause of sundowning is not fully understood but may be related to factors such as fatigue, sensory overload, hormonal imbalances, or disruptions in the sleep-wake cycle. Managing sundowning behaviors often involves creating a calming environment, maintaining a consistent daily routine, minimizing stimuli in the evening, and providing reassurance and comfort to the individual.

D. Depression: Depression can occur in individuals with Alzheimer's disease and may present with symptoms such as sadness, hopelessness, loss of interest in activities, changes in appetite or sleep patterns, and difficulty concentrating. However, the scenario primarily describes agitation and restlessness in the evening hours, which is characteristic of sundowning rather than depression.
