A nurse is teaching a client about health conditions that increase the risk for developing Meniere’s disease. Which of the following factors should the nurse include in the teaching?

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.

A. Respiratory rate of 12/min: A respiratory rate of 12/min is within the normal adult range (12-20 breaths per minute). In the context of increased intracranial pressure (ICP), respiratory rate changes might be noted as part of the Cushing's reflex (which is characterized by bradycardia, hypertension, and abnormal respiratory patterns like Cheyne-Stokes or ataxic breathing), but a rate of 12/min on its own is not indicative of a worsening condition. However, if the patient begins to show signs of irregular or abnormal breathing patterns, this would raise concern.

B. Blood pressure of 108/74 mm Hg: This blood pressure is also within the normal range and does not suggest a worsening of intracranial pressure. In fact, ICP can lead to a rise in blood pressure (due to the body's compensatory mechanisms, known as Cushing's triad), along with bradycardia and abnormal respirations. Thus, a stable blood pressure like 108/74 mm Hg is not concerning in this context.

C. Changes to pupil size and shape: Changes in pupil size, shape, or reactivity are significant indicators of worsening intracranial pressure. Unequal pupils (anisocoria), sluggish or absent response to light, and fixed dilated pupils are signs of brainstem compression or damage, which often occur as ICP increases. This could indicate herniation or severe brain injury, which are worsening conditions.

D. Swelling of the optic nerve: Swelling of the optic nerve, or papilledema, is another important sign of increased intracranial pressure. It occurs due to increased pressure within the skull, which causes congestion and swelling of the optic disc. This finding can be seen on fundoscopy and indicates a worsening condition, as it suggests elevated pressure affecting the brain.

E. Decreasing Glasgow Coma scores: A decreasing Glasgow Coma Scale (GCS) score is a critical indicator of worsening neurologic function in a patient with increased ICP. The GCS is used to assess a patient's level of consciousness, and a decreasing score suggests that the brain's function is deteriorating. This can be caused by worsening edema, brain herniation, or other severe neurological impairments associated with elevated ICP.
