Mental Health Flashcards
How should the nurse re-orient a patient with dementia back to reality?
Photo albums and reminiscing assist with reality orientation
using calendars and clocks assists with orientation to time
creating large signs can help a patient locate rooms.
What is the BEERS list?
The Beers Criteria for Potentially Inappropriate Medication Use in Older Adults is a list of medications that healthcare providers reference to safely prescribe medications for people above age 65.
Expected change in cognition with aging in regards to attention.
Divided attention may decline as ability to prioritize declines
Expected change in cognition with aging in regards to intelligence.
Fluid (newer knowledge), decline in ability to store new knowledge
Expected change in cognition with aging in regards to language.
Word retrieval or name recall, slow and difficult to retreive
Expected change in cognition with aging in regards to memory.
Recent or new memories, may decline
Expected change in cognition with aging in regards to problem solving.
Takes longer to solve new problems
Expected change in cognition with aging in regards to speed of processing.
Cognitive and motor processing are stable but take longer to perform
What is the role of Acetylcholine in cognition?
Critical for memory, learning, and attention. ↓ levels are strongly linked with Alzheimer’s disease.
Acetylcholine is crucial for various cognitive functions and its deficiency is associated with cognitive decline.
What cognitive functions is Dopamine involved in?
Motivation, reward, attention, and executive functions (planning, problem-solving). Imbalances are linked with Parkinson’s and schizophrenia.
Dopamine plays a significant role in the brain’s reward system and cognitive processes.
What does Serotonin regulate?
Mood, sleep, emotion, and contributes to memory and learning. Low levels are linked to depression and anxiety.
Serotonin is often referred to as the ‘feel-good’ neurotransmitter.
What is the role of Norepinephrine in cognition?
Supports alertness, arousal, attention, and stress response. Plays a role in focus and decision-making. Dysregulation is involved in ADHD and depression.
Norepinephrine is important for the body’s fight-or-flight response and cognitive clarity.
What is Glutamate’s significance in the brain?
The primary excitatory neurotransmitter. Essential for learning and memory formation. Overactivity may lead to neurotoxicity (e.g., in stroke or Alzheimer’s).
Glutamate is vital for synaptic plasticity, which underlies learning.
What is GABA’s function in the brain?
The main inhibitory neurotransmitter. Helps regulate anxiety, sleep, and calms overactive brain circuits. Too little can lead to anxiety and seizures.
GABA plays a key role in maintaining the balance of neural activity.
What is the effect of Vitamin B1 (Thiamine) deficiency for neurotransmitters?
Needed for acetylcholine synthesis; deficiency → Wernicke’s encephalopathy
What is Vitamin B6 (Pyridoxine) required for which neurotransmitters?
Required for serotonin, dopamine, GABA production
What is the role of Vitamin B12 & Folate for neurotransmitters?
Needed for methylation (essential for NT synthesis: serotonin, epinephrine, and dopamine); deficiencies can cause cognitive decline
Vitamin B12 deficiency impacts the synthesis of neurotransmitters and may contribute to the development of anxiety and depression.
What neurotransmitter is Vitamin C involved in?
Involved in dopamine synthesis
What are SSRIs?
Selective Serotonin Reuptake Inhibitors (SSRIs) include Fluoxetine, Sertraline, and Escitalopram.
They increase serotonin by blocking reuptake.
Indications: Depression, GAD, panic disorder, OCD, PTSD.
Patient education: Takes 2–4 weeks to work; may cause GI upset, insomnia, sexual dysfunction; risk of serotonin syndrome; don’t stop abruptly.
What are SNRIs?
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) include Venlafaxine and Duloxetine.
They block the reuptake of serotonin and norepinephrine.
Indications: Depression, GAD, chronic pain, fibromyalgia.
Patient education: May increase BP; taper to avoid withdrawal; monitor for mood changes.
What are TCAs?
Tricyclic Antidepressants (TCAs) include Amitriptyline and Nortriptyline.
They block the reuptake of serotonin and norepinephrine.
Indications: Depression, neuropathic pain, insomnia, migraine prevention.
Patient education: Can cause sedation, weight gain, anticholinergic effects (dry mouth, constipation); cardiotoxic in overdose.
What are MAOIs?
Monoamine Oxidase Inhibitors (MAOIs) include Phenelzine and Tranylcypromine.
They inhibit the breakdown of serotonin, dopamine, and norepinephrine.
Indications: Treatment-resistant depression, atypical depression.
Patient education: Avoid tyramine-rich foods (aged cheese, wine); many drug interactions; risk of hypertensive crisis.
What are Atypical Antidepressants?
Atypical Antidepressants include Bupropion and Mirtazapine.
Bupropion inhibits dopamine/NE reuptake; Mirtazapine has serotonin/NE effects.
Indications: Depression, smoking cessation (Bupropion), insomnia and appetite loss (Mirtazapine).
Patient education: Bupropion lowers seizure threshold, avoid in eating disorders; Mirtazapine causes drowsiness and weight gain.
What are Benzodiazepines?
Benzodiazepines include Lorazepam, Diazepam, and Alprazolam.
They enhance GABA (inhibitory neurotransmitter).
Indications: Acute anxiety, panic attacks, alcohol withdrawal.
Patient education: Short-term only (risk of dependence); causes sedation; avoid alcohol; don’t stop suddenly.
