Benzodiazepine : Anxiolytics withdrawal symptoms

- Develops slowly, in 2 to 10 days, and may last several weeks - Withdrawal symptoms *Paranoia, delirium/panic *Hypertension, seizures *Status epilepticus

Psychosis characteristics

- Difficulty in processing information - Disorganized thoughts, incoherence - Distortion of reality - Delusions, hallucinations, catatonia - Aggressive or violent behavior

clozapine side effects

- Dizziness, sedation, constipation - Tachycardia, orthostatic hypotension - Tremors, occasional rigidity - Seizures, Low possibility of EPS

Benzodiazepine : Anxiolytics side effects

- Drowsiness, dizziness, ataxia, restlessness, weakness - Headache, confusion, amnesia, blurred vision - Bradycardia, hypotension/hypertension- Seizures, erectile dysfunction

Aripiprazole side effects

- Drowsiness, dizziness, headache, dry mouth - Anxiety, agitation, memory impairment - Blurred vision, weight gain/loss, insomnia - Urinary retention, GI distress, constipation - Tachycardia, orthostatic hypotension, erectile dysfunction - Low possibility of EPS and tardive dyskinesia

atypical antipsychotics advantages

- Effective in treating both positive and negative symptoms of schizophrenia - Less likely to cause EPS or tardive dyskinesia

neuropsychology

- Impulse triggers release of various neurotransmitters - After action exerted, NT removed and broken down, diffused away, or reuptaken - GABA: inhibitory NT - Dopamine: regulates cognition, emotion, motivation - Serotonin: regulates emotions and digestion44

secondary anxiety

- It is related to selected drug use, medical or psychiatric conditions. - Medications are not usually given for secondary anxiety - treat the causative condition

risperidone use

- Manage symptoms of psychosis - Treats positive and negative symptoms of schizophrenia

risperidone side effects

- Sedation, headaches, photosensitivity, dry mouth, weight gain, tachycardia, orthostatic hypotension, urinary retention, sexual dysfunction, seizures - Low risk EPS and TD

Nursing Process : Phenothiazines and Nonphenothiazines

- VS - remain with patient while med is taken and swallowed - observe for EPS - may take 6 weeks to achieve full effect - caution patients not to consume alcohol or other CNS depressants such as opioids

Which treatment may be necessary to manage a patient with a benzodiazepine overdose?

- admin IV flumazenil - provide O2 for respiratory depression - provide IV vasopressors for severe hypo

Phenothiazines

- block norepinephrine, causing sedative and hypotensive effects early in treatment - Chloropromazine (Thorazine)

Nonphenothiazines

- block only the neurotransmitter dopamine - Butyrophenones: Haloperidol, droperidol

cognitive symptoms of schizo

- disorganized thinking, memory difficulty - decreased ability to focus attention

atypical antipsychotics side effects

- drowsiness, headache, unsteady gait, insomnia - depression, weight gain, dyslipidemia, diabetes mellitus

antipsychotics adverse effects

- extrapyramidal symptoms (EPS) or pseudoparkinsonism - tremors, masklike facies, rigidity, shuffling gait

psychosis

- loss of contact with reality - theory: results from imbalance in neurotransmitter dopamine in the brain

Non pharmacological therapy for anxiety

- relaxation - meditation - support system establishment - exercise - CBT

Pharmacological treatment for anxiety

- short term: benzodiazepine - long term: SNRI or SSRI (takes 2-4 week for clinical effects)

Benzodiazepine nursing process

- side effects of anxiolytics - VS - encourage family to be supportive - do not drive bc of sedation side effect - do not consume alcohol or CNS depressant

Which consideration would the nurse take when administering haloperidol decanoate?

Administer the injection using the Z-track method

Haloperidol action

Alters dopamine effect by blocking dopamine receptors

Which action would the nurse take when providing care to a patient who has recently been prescribed a benzodiazepine?

Assess sedation level

Which condition is the patient most likely experiencing when prescribed alprazolam?

Anxiety with depression

Benzodiazepine

Anxiolytics - Lorazepam, diazepam, alprazolam - gradually decrease dose with discontinuation

atypical antipsychotics action

Block serotonin and dopaminergic D4 receptors

Miscellaneous Anxiolytics
