NSG 552 Exam 1 Antidepressants 2026 – 75+ Practice Questions on SSRIs, SNRIs, TCAs, MAOIs & Depression Pharmacotherapy

This comprehensive NSG 552 Exam 1 Antidepressants study guide contains over 75 high-yield practice questions and answers covering the neurobiology of depression, antidepressant classifications, medication mechanisms of action, adverse effect management, and evidence-based prescribing principles essential for psychiatric nursing practice. Designed for graduate nursing students and advanced practice providers, this resource converts complex psychopharmacology concepts into an active recall format that strengthens clinical reasoning, enhances medication safety awareness, and improves performance on psychiatric nursing examinations and certification assessments. The material integrates pharmacodynamics, therapeutic applications, patient counseling considerations, and treatment strategies frequently emphasized in Psychiatric Mental Health Nurse Practitioner (PMHNP) programs and advanced psychopharmacology courses. The guide begins with an in-depth review of the monoamine theory of depression, emphasizing the critical roles of serotonin, norepinephrine, and dopamine in mood regulation and the pathophysiology of depressive disorders. Students will strengthen their understanding of how alterations in neurotransmitter activity contribute to depressive symptoms and how antidepressant medications target these pathways to restore neurochemical balance and improve clinical outcomes. Extensive coverage of Selective Serotonin Reuptake Inhibitors (SSRIs) examines their mechanisms of action, therapeutic advantages, and role as first-line agents in the treatment of Major Depressive Disorder (MDD). Learners will review medication-specific characteristics of commonly prescribed SSRIs, including fluoxetine, sertraline, paroxetine, citalopram, fluvoxamine, and their unique clinical applications. Topics include differences in half-life, FDA-approved indications, pregnancy considerations, overdose safety profiles, and the management of common adverse effects such as gastrointestinal disturbances, insomnia, agitation, hyponatremia, bleeding risk, and sexual dysfunction. The resource provides detailed exploration of Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs), Norepinephrine-Dopamine Reuptake Inhibitors (NDRIs), Serotonin Receptor Antagonists and Reuptake Inhibitors (SARIs), and Noradrenergic and Specific Serotonergic Antidepressants (NaSSAs). Students will develop a thorough understanding of bupropion, trazodone, mirtazapine, duloxetine, and venlafaxine, including their mechanisms of action, target symptoms, advantages, contraindications, and adverse effect profiles. Clinical applications such as smoking cessation, treatment of antidepressant-induced sexual dysfunction, insomnia management, appetite stimulation, and symptom-based medication selection are emphasized to support individualized treatment planning. Comprehensive review of Tricyclic Antidepressants (TCAs) highlights their pharmacologic properties, therapeutic uses, and significant safety considerations. Learners will examine medications such as amitriptyline, imipramine, clomipramine, nortriptyline, desipramine, and amoxapine while differentiating their roles in depression, obsessive-compulsive disorder, enuresis, chronic pain syndromes, migraine prophylaxis, and insomnia. The guide also addresses anticholinergic effects, cardiovascular toxicity, seizure risk, overdose lethality, electrocardiographic abnormalities, and evidence-based strategies for managing TCA overdose. Monoamine Oxidase Inhibitors (MAOIs) are reviewed extensively through discussions of their mechanisms, clinical indications, dietary restrictions, and drug interaction precautions. Students will strengthen their understanding of tyramine-containing foods, hypertensive crisis prevention, serotonin syndrome risk, medication washout periods, and the distinctive role of agents such as phenelzine and transdermal selegiline in treatment-resistant depression and atypical depressive presentations. Special emphasis is placed on antidepressant safety, monitoring, and patient counseling. Topics include antidepressant discontinuation syndrome, serotonin syndrome recognition, black box warnings regarding suicidality in children and adolescents, antidepressant selection during pregnancy, sedating versus activating antidepressant profiles, and evidence-based interventions for managing antidepressant-induced sexual dysfunction. These concepts support safe prescribing practices and strengthen learners' confidence in psychopharmacologic decision-making. This study guide is particularly valuable for Psychiatric Mental Health Nurse Practitioner (PMHNP) students, Master of Science in Nursing (MSN) students, Doctor of Nursing Practice (DNP) students, psychiatric nursing students, advanced practice registered nurses, physician assistant students specializing in behavioral health, psychiatry residents, nurse practitioner certification candidates, and healthcare professionals seeking a focused review of antidepressant pharmacotherapy.
