Comprehensive Study Guide for Mental Health, Pharmacology, and Neurocognitive Disorders

Autonomic Nervous System Functions

• Parasympathetic Nervous System Actions: A primary action characteristic of the parasympathetic system is the constriction of the smooth muscles of the lungs, which results in restricted airways.
• Sympathetic Nervous System Functions: This system prepares the human body for immediate adaptation by triggering the "fight-or-flight" response.

Psychopharmacology and Nursing Care Guidelines

• Nursing Responsibilities for Drug Therapy: There are four ($4$) essential client care guidelines for nurses administering psychotherapeutic medications:
      * Monitoring for therapeutic effects.
      * Observing for adverse reactions.
      * Providing comprehensive medication teaching to the client.
      * Ensuring the safe administration of all medications.
• Lithium Therapy:
      * Primary Purpose: Used to stabilize mood in clients with bipolar disorder.
      * Monitoring Requirements: Salt intake must be strictly monitored because salt and lithium compete for excretion within the kidney. Success of therapy requires monitoring the serum lithium level.
      * Early Toxicity Signs: A common early indicator of lithium toxicity is the presence of a tremor.
• Tricyclic Drugs (Antidepressants):
      * Indications: Primary treatment for depression.
      * Side Effects: Commonly associated with anticholinergic side effects.
• Benzodiazepines: These medications are specifically used to treat anxiety.
• Priority Interventions:
      * Hypertensive Crisis: Characterized by a stiff neck, throbbing headache, and tightness in the chest. The priority nursing action is to stop the medication and notify the provider immediately.
      * Severe Depression: A key safety concern for clients on antidepressants is the elevated risk for suicide.

Movement Disorders and Medication Side Effects

• Extrapyramidal Side Effects (EPSEs):
      * Symptoms: Feeling jittery, inability to sit still (akathisia), and problems with eye movements.
      * Categorization: EPSEs encompass akathisia, dyskinesia, and akinesia.
• Anticholinergic Reaction Symptoms: These include dry mouth, blurred vision, and excessive sweating.
• Akathisia: Specific form of EPSE involving extreme restlessness and an inability to remain still.

Cognitive and Clinical Definitions

• Noncompliance: Defined as an informed decision made by a client not to follow the treatment program prescribed by their healthcare provider.
• Delirium: A change of consciousness that occurs at a rapid or quick pace.
• Conative Loss: The loss of the ability to create and carry out specific plans.
• Aphasia: The loss of an individual's ability to use or understand language.
• Apraxia: The loss of the ability to perform everyday activities and actions.
• Agnosia: The loss of recognition regarding previously known or familiar objects and people.
• Mutism: The loss of the ability to speak, where the individual may only be able to grunt.

Alzheimer’s Disease and Neurocognitive Disorders

• Alzheimer’s Disease Comprehensive Definition: The loss of multiple global abilities, including memory, language, and complex thinking.
• General Health Care Goals: Alzheimer's care is centered around three ($3$) goals:
      * Maintaining safety.
      * Maintaining function.
      * Providing comfort.
• Stages of Alzheimer’s Progression:
      * Early Stage: Characterized by being social but exhibiting strange behaviors and frequent mood swings.
      * Middle Stage: Includes difficulty performing Activities of Daily Living (ADLs), wandering, agitation, physical aggression, aphasia, apraxia, and visual agnosia.
      * Late Stage: Characterized by an inability to swallow, which significantly increases the risk for pneumonia and malnutrition.

Sleep-Wake Disorders

• General Terms:
      * Dyssomnia: An abnormality regarding the amount, quality, or timing of sleep.
      * Parasomnia: Abnormal behaviors or physical events occurring during sleep.
      * Polysomnogram: A diagnostic tool that monitors electrophysical responses during the sleep cycle.
• Specific Disorders:
      * Insomnia: A disorder characterized by falling or staying asleep. The primary nursing intervention is the promotion of sleep hygiene.
      * Narcolepsy: Characterized by repeated sleep attacks and a sudden loss of muscle control.
      * Sleep Apnea: Characterized by abnormal ventilation and the hallmark symptom of pauses in breathing during sleep.
      * Hypersomnia: A condition of excessive sleepiness.

Eating Disorders and Obesity

• Anorexia Nervosa:
      * Key Features: Extreme restriction of food intake and a refusal to maintain normal body weight due to an intense fear of becoming fat.
      * Clinical Significance: This is a mental health disorder characterized by a high mortality rate.
• Bulimia Nervosa:
      * Key Features: Recurrent binge eating coupled with the use of inappropriate methods to prevent weight gain (purging).
• Obesity: Defined as having excessive body weight.
• Treatment Goal: The main goal for treating eating disorders is to restore nutritional status and normalize eating patterns.

Behavioral Health: Aggression and Violence

• Conceptual Frameworks:
      * Violence: Forceful behaviors resulting in injury, abuse, or harm to others.
      * Interpersonal/Social Learning Theories: Models that focus on social interaction and the surrounding environment.
      * Gender Violence: The abuse of members of one gender by another.
• Factors Contributing to Aggression: Frustration, learned behavior, substance use, and environmental stressors.
• Client Behaviors:
      * Acting Out: Common in children and adolescents as an attempt to establish limits.
      * Passive Aggressive Behavior: An indirect expression of anger while the individual appears to be compliant.
• Phases of the Assault Cycle:
      * Trigger Stage: The individual loses the ability to reason and may appear flushed or pale. The goal of intervention here is to prevent escalation to violence.
      * Escalation Stage: Monitoring for clinical signs such as restlessness, irritability, arguing, and pacing.
      * Crisis Stage: The individual loses total control and may fight, kick, bite, or scream.
      * Reconciliation Stage: The individual cries, apologizes, or attempts to atone for their behavior.
• Aggression Management:
      * Safety: Ensuring the safety of the client and staff is the most important initial intervention in a violent situation.
      * Last Resort Interventions: Restraints or seclusion are considered the final intervention options.
      * Rapid Assessment: Clinicians must perform rapid assessments of potentially violent clients.
      * Provider Experience: It is false to assume that care providers never experience anger or aggression themselves.
