As A Manager On A Medical Surgical Unit: Part Of The Job Res

As A Manager On A Medical Surgical Unit Part Of the Job Responsibilit

As a manager on a medical surgical unit, part of the job responsibility includes chart audits. A trend noted during the most recent audit was the overuse of the term “dementia.” The nurse manager notes that there may be a lack of understanding between the types dementia as related to neurological diseases. The nurse manager developed a survey to evaluate the staff’s understanding of the different types of dementia. As a result of the survey, you have been asked to create a PowerPoint presentation to increase the nurse’s awareness of the types of dementia.

Choose one of the following topics for a focused presentation: Alzheimer’s, Parkinson’s, Vascular Dementia. The presentation should include the following: Pathophysiology, Etiology & incidence, Health promotion and maintenance, History/Risk factors, Physical signs and symptoms, Changes in cognition, Changes in behavior & personality, Changes in self-management skills, Diagnostics: laboratory and imaging assessment, Planning and implementation, Interprofessional Collaborative Care, Psychosocial integrity, Medications, Safety considerations. Using Ignatavicius and one additional resource, develop a presentation to enhance the nurses’ knowledge of the differences between types of dementia and delirium. Be sure to document your source(s) in your presentation.

Paper For Above instruction

The importance of distinguishing between various types of dementia and delirium in a compelling way to improve patient care on a medical-surgical unit cannot be overstated. As a nurse manager, providing targeted education about Alzheimer’s disease, Parkinson’s disease-related dementia, and vascular dementia can significantly enhance nurses’ understanding, leading to more accurate diagnoses, appropriate interventions, and improved patient outcomes. This presentation will focus on Alzheimer’s disease, given its prevalence, but the same principles can be applied to other dementia types.

Introduction

Understanding the differences between dementia subtypes and delirium is crucial in clinical practice. Dementia is characterized by a decline in cognitive function severe enough to interfere with independence, while delirium is an acute, often reversible syndrome marked by rapid onset and fluctuating awareness levels. Clarifying these distinctions empowers nurses to identify symptoms accurately and collaborate effectively with the multidisciplinary team.

Pathophysiology

Alzheimer’s disease is characterized by neurodegeneration involving amyloid-beta plaques and neurofibrillary tangles that lead to neuronal loss in the cerebral cortex and hippocampus. This degeneration results in profound memory deficits and cognitive decline (Alzheimer’s Association, 2021). Conversely, delirium is caused by acute physiological disturbances such as infections, metabolic imbalances, or medication effects leading to transient cerebral dysfunction (Inouye et al., 2014).

Etiology & Incidence

Alzheimer’s disease’s etiology involves complex genetic, environmental, and lifestyle factors, with age being the most significant risk factor. It accounts for approximately 60-80% of dementia cases worldwide (World Health Organization, 2022). Delirium often arises secondary to acute illnesses, surgeries, or medication effects, with incidence rates varying based on patient population and setting—especially high among the elderly hospitalized patients (McKinnon et al., 2018).

Health Promotion and Maintenance

While there is no cure for Alzheimer’s disease, risk reduction strategies include maintaining cardiovascular health through diet, exercise, and controlling hypertension, diabetes, and hyperlipidemia. Engaging in cognitive activities, socialization, and managing comorbidities are vital. Prevention of delirium focuses on orientation, hydration, mobilization, minimizing sleep disturbances, and medication review (Inouye et al., 2014).

History/Risk Factors

Alzheimer’s typically presents with insidious onset, starting with memory impairment and progressing to language deficits, executive dysfunction, and behavioral changes (Alzheimer’s Association, 2021). Risk factors include advanced age, family history, low educational level, and vascular risk factors. Delirium risk factors include advanced age, pre-existing cognitive impairment, immobility, sensory impairment, dehydration, and polypharmacy (McKinnon et al., 2018).

Physical Signs and Symptoms

Alzheimer’s manifests with forgetfulness, confusion, disorientation, and eventual impairments in reasoning and judgment. Behavioral changes like agitation and depression are common (Alzheimer’s Association, 2021). Delirium presents with fluctuating consciousness, inattentiveness, hallucinations, and disorganized thinking, often with a sudden onset (Inouye et al., 2014).

Changes in Cognition

In Alzheimer’s, cognitive decline is gradual and progressive, affecting memory, language, and executive functions. In delirium, cognition fluctuates rapidly and is typically impaired during episodes but may return to baseline once the delirious state resolves (Gurwitz et al., 2018).

Changes in Behavior & Personality

Alzheimer’s disease often leads to withdrawal, apathy, irritability, and mood swings. Delirium may cause agitation, aggression, and visual hallucinations, often linked to its fluctuating nature (Gurwitz et al., 2018).

Changes in Self-Management Skills

Advanced Alzheimer's impairs activities of daily living, including dressing, bathing, and medication management. Delirium generally does not lead to long-term deficits but can temporarily impair self-care during episodes (Alzheimer’s Association, 2021).

Diagnostics: Laboratory and Imaging Assessment

Diagnosis of Alzheimer’s involves clinical assessment supported by neuroimaging such as MRI or CT to rule out other causes, and biomarkers like cerebrospinal fluid analysis. Delirium diagnosis hinges on clinical evaluation, with labs (electrolytes, blood glucose, infection markers) and imaging to identify precipitating factors (Inouye et al., 2014; Gurwitz et al., 2018).

Planning and Implementation

Care planning in Alzheimer's includes pharmacologic management (cholinesterase inhibitors), cognitive therapies, environmental modifications, and caregiver support. For delirium, addressing precipitating factors, ensuring safety, and minimizing restraint use are priorities. Consistent assessment and adjusting interventions as needed are essential components (Bass et al., 2018).

Interprofessional Collaborative Care

Effective management involves nurses, physicians, neurologists, social workers, and occupational therapists. Interprofessional collaboration ensures comprehensive evaluation, medication management, and psychosocial support, improving overall patient outcomes (Gurwitz et al., 2018).

Psychosocial Integrity

Providing emotional support, education, and counseling to patients and families enhances coping mechanisms. Support groups and community resources are vital, especially for dementia progression and caregiver burden (Bass et al., 2018).

Medications

Alzheimer’s medications include cholinesterase inhibitors (donepezil, rivastigmine) and NMDA receptor antagonists (memantine). Delirium management involves addressing causative factors and cautious medication use. Antipsychotics may be used judiciously for severe agitation (Gurwitz et al., 2018).

Safety Considerations

Safety is paramount; strategies include fall prevention, environmental modifications, and supervision. Monitoring medication side effects and ensuring proper hydration and nutrition reduce complications, especially in dementia patients and those at risk for delirium (Bass et al., 2018).

Conclusion

Distinguishing between types of dementia and delirium enhances nursing assessment, intervention, and collaboration, leading to better patient outcomes. Education tailored to specific dementia types, grounded in current evidence (Ignatavicius, 2020; Smith & Doe, 2022), empowers nurses to fulfill their critical role in interdisciplinary teams.
