CNA Nursing Assistant Certification Review
Understanding Special Needs Populations
Intellectual Disability
Individuals with intellectual disabilities often face challenges in thinking, learning, and achieving developmental milestones. They typically have an IQ lower than the normal range, which can significantly impact their ability to conduct activities of daily living (ADLs). The role of a nursing assistant is crucial in adapting care to the resident’s developmental stage and providing proper support.
Cerebral Palsy
Cerebral palsy is a movement disorder that results from damage to the brain, potentially occurring during birth or pregnancy. It is a lifelong condition that may accompany intellectual disabilities and various muscle function problems. Symptoms can vary significantly from one individual to another, necessitating that nursing assistants tailor activities to the resident's developmental and physical capabilities.
Epilepsy
This is a disorder characterized by seizures, which may not always have a known cause. Seizures can be triggered by various factors and are typically treated with medication. Symptoms differ depending on which part of the brain is affected and the type of seizure experienced by the resident.
Parkinson’s Disease
Parkinson’s disease is chronic and progressive, caused by a loss of dopamine-producing cells in the brain. As the disease progresses, motor abilities decrease, leading to late symptoms such as purposeful movement loss, hallucinations, dementia, and incontinence. Nursing assistants should be aware of these changes and adjust their care appropriately.
Mental Illness
Mental illness encompasses various conditions affecting mood, behavior, and thought processes. Many individuals can manage their symptoms effectively with medication and therapy. It’s essential for nursing assistants to be sensitive to the needs of these residents, providing support, reassurance, and understanding.
Understanding Alzheimer’s Disease and Related Dementias
Types of Dementia
Alzheimer's Disease: The most common form, accounting for 60-70% of dementia cases, characterized by plaques and tangles in the brain.
Vascular Dementia: Resulting from reduced blood flow to the brain.
Lewy Body Dementia: Occurs alongside Parkinson’s disease, head trauma, or other conditions.
Risk Factors for Dementia
Key risk factors include age (65 years or older), high cholesterol, genetics, uncontrolled diabetes, high blood pressure, depression, smoking, and alcoholism.
Treatment of Dementia
While dementia is a progressive and incurable disease, various approved medications can help slow or manage symptoms. Different therapies, such as behavioral and sensory stimulation, play a vital role in care.
Diagnosing Dementia
Diagnosis involves observing warning signs such as memory loss, poor decision-making, personality changes, and difficulty with everyday tasks. Healthcare providers typically conduct a thorough examination, including lab tests.
Stages of Alzheimer's Disease
Mild (Early Stage): Often recognized by family only; includes difficulty with names and planning activities.
Moderate (Middle Stage): Symptoms intensify with increased mood swings, use of confusing terms, and forgetfulness regarding personal history.
Severe (Late Stage): Residents may struggle with communication and require constant care, as mobility and basic functioning decline significantly.
Common Signs of Dementia
Residents may display various behavioral changes such as memory loss, agitation, inappropriate behavior, and difficulty with communication.
Strategies for Supporting Residents with Dementia
Meeting Unmet Needs: Nursing assistants should help with basic needs, such as toileting, hydration, and mobility, to improve resident comfort.
Therapeutic Interventions: Activities like reminiscence, sensory stimulation, and pet therapy can be beneficial.
Maintaining Function: Encouraging independence in activities of daily living (ADLs) while providing the necessary support is crucial for residents' dignity and self-esteem.
Managing Mealtime: Strategies include offering finger foods, using small utensils, maintaining a calm environment, and encouraging social interaction during meals to improve appetite and comfort.
Pain Management: It’s important to observe non-verbal cues indicative of pain and address these promptly, using both pharmacological and non-pharmacological strategies.
Holistic Care and Growth Development
Holistic care addresses the physical, emotional, social, and spiritual needs of residents, adapting to their specific conditions and circumstances. Recognizing and applying Maslow’s hierarchy of needs in caregiving can help enhance the quality of life for residents, ensuring their basic physiological needs are met first, followed by safety, belonging, esteem, and self-actualization.
Erikson's Stages of Development
Nursing assistants should understand various developmental stages from infancy to senior adulthood, recognizing that chronological age doesn't always align with developmental needs or abilities.
Community Resources and Quality of Life
Significant resources exist to support residents and enhance their quality of life, including volunteer groups, hospice care, and services for veterans. Nursing assistants play a vital role in identifying when residents might benefit from additional support. Activities therapy can also maintain or enhance resident interests while promoting overall wellness.
Common Diseases and Disorders
Various physical and psychological diseases impact residents' overall health. Disease processes within systems such as integumentary, musculoskeletal, respiratory, cardiovascular, nervous, endocrine, digestive, urinary, reproductive, and cancers must be understood to provide effective holistic care
Specific Disease Management
Understanding the signs, symptoms, and treatments for conditions—ranging from chronic diseases like diabetes and hypertension to acute illnesses—is crucial for timely intervention and enhancing the quality of care.
Care for Residents with Special Conditions
Caring for residents with conditions like HIV/AIDS and cancer requires specific knowledge about the diseases, treatments, and associated care strategies to ensure they receive appropriate and respectful care throughout their journey.
