Varcarolis’ Foundations of Psychiatric Mental Health Nursing: A Clinical Approach | Margaret Jordan Halter (8th Edition) - Psychopharmacology and Other Biological Treatments | Chapter 33 - Psychiatric Mental Health Nursing

Chapter 33 of Foundations of Psychiatric Mental Health Nursing: A Clinical Approach (8th Edition) provides a comprehensive overview of psychopharmacology and biological treatments in psychiatric nursing. The chapter begins with principles of psychopharmacology, including pharmacokinetics, pharmacodynamics, and the role of neurotransmitters such as serotonin, dopamine, norepinephrine, and GABA in mental illness. Major classes of psychotropic medications are reviewed: antidepressants (SSRIs, SNRIs, TCAs, MAOIs, atypical agents), antipsychotics (typical and atypical), mood stabilizers (lithium, anticonvulsants), and anxiolytics (benzodiazepines, buspirone, beta-blockers). The chapter outlines indications, mechanisms of action, therapeutic effects, and adverse reactions, including serotonin syndrome, extrapyramidal side effects (EPS), neuroleptic malignant syndrome (NMS), and metabolic syndrome. Nurses are guided in medication administration, monitoring therapeutic response, managing side effects, ensuring adherence, and providing patient education. Special considerations include polypharmacy, drug-drug interactions, and pharmacogenomics. The chapter also explores somatic treatments such as electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), vagus nerve stimulation (VNS), and deep brain stimulation (DBS), highlighting their indications, procedures, benefits, and risks. Ethical issues such as informed consent, stigma, and patient autonomy are emphasized throughout. Nurses play a critical role in supporting patients by combining pharmacological knowledge with therapeutic communication and holistic care, helping individuals achieve stability, reduce symptoms, and improve quality of life. By integrating psychopharmacology with biological and psychosocial interventions, this chapter equips psychiatric-mental health nurses to provide safe, evidence-based, and person-centered care. 📘 Read full blog summaries for every chapter: https://lastminutelecture.com 📘 Have a book recommendation?
