NURS 660 Exam 3 2026 – 80 Questions & Answers with Rationales on Psychopharmacology, Anxiety Disorders & Sleep Mechanisms

This document contains approximately 80 exam-style questions and verified answers with rationales for NURS 660 Exam 3, focusing on psychopharmacology, anxiety disorders, and sleep-wake regulation. It covers key topics such as medication mechanisms of action, neurotransmitter pathways, anxiety-related diagnoses, and pharmacological treatments . The material provides in-depth coverage of essential psychiatric and pharmacological concepts. Early sections (page 1–2) include drug-specific knowledge such as antidotes (e.g., flumazenil for alprazolam) and mechanisms of action like pregabalin binding to calcium channels and caffeine antagonism via adenosine pathways. It further explores psychiatric diagnoses including generalized anxiety disorder (GAD), panic disorder, PTSD, and social anxiety, along with associated brain structures such as the amygdala and hippocampus. Later sections expand into sleep and neurobiology, detailing the role of neurotransmitters like GABA, histamine, dopamine, and melatonin in regulating sleep and wakefulness (pages 6–8). It also includes pharmacologic treatments such as SSRIs, benzodiazepines, buspirone, modafinil, and melatonin agonists, with emphasis on mechanisms, indications, and safety considerations. Clinical scenarios—such as alcohol withdrawal management with lorazepam, contraindications in liver disease, and treatment strategies for fibromyalgia and neuropathic pain—are integrated throughout, making this a highly practical exam preparation resource. This document is ideal for students and professionals enrolled in Advanced Practice Nursing, Psychiatric Nursing, Pharmacology, Mental Health Nursing, and Nurse Practitioner (NP) programs. It is particularly beneficial for graduate nursing students, PMHNP candidates, and healthcare professionals preparing for advanced nursing exams or clinical practice in mental health and pharmacology. The content aligns closely with standard references such as Stahl’s Essential Psychopharmacology and advanced nursing pharmacology course materials. It serves as a complete study guide and practice exam resource, helping learners strengthen both theoretical understanding and clinical decision-making skills.
