INSTANT PDF DOWNLOAD—This comprehensive study guide is specifically designed for Maryville University graduate nursing students (PMHNP, FNP) preparing for NURS 660 Psychopharmacology and Advanced Mental Health Exam 3 for the 2026/2027 academic year. Based on verified exam materials from top-selling student resources, this resource contains expertly verified practice questions and 100% correct answers with detailed rationales to help you master core psychopharmacology concepts and achieve a top score (Grade A+) . This comprehensive guide covers all major topics tested on NURS 660 Exam 3 : Neuroanatomy of Anxiety & Fear: Amygdala (fear response, memory of stimuli, glutaminergic neurotransmission, NMDA receptors) , hippocampus (memory coding/retrieval, re-experiencing in PTSD, internal fearmongering) , parabrachial nucleus (respiratory response: shortness of breath, asthma, sense of being smothered) , periaqueductal gray (motor response: fight/flight/freeze) , locus coeruleus (cardiovascular response: increased norepinephrine, HR, BP) , hypothalamus (sleep-wake switch, histamine/GABA regulation) , prefrontal cortex (worry circuit, CSTC loop, dopamine, serotonin, GABA) . Pain Pathways & Neurophysiology: A-beta fibers (small movements, light touch, vibrations) ; A-delta fibers (noxious mechanical stimuli, subnoxious thermal stimuli) ; C-fibers (bare nerve endings activated by noxious mechanical, thermal, chemical stimuli) ; allodynia (pain from non-painful stimulus) ; hyperalgesia (increased pain from normally painful stimulus) ; nociceptive pain (actual or threatened tissue damage) ; neuropathic pain (lesion or disease of somatosensory nervous system) ; central sensitization (increased CNS responsiveness) ; peripheral neuropathy (diabetic neuropathy, postherpetic neuralgia) ; chronic pain pathophysiology (changes in ascending/descending pathways, grey matter loss, central sensitization) . Benzodiazepines & Anxiety Treatment: MOA (binds to GABA-A receptors, PAM, increases frequency of chloride channel opening) ; indications for GAD and panic disorder; contraindications (alcohol, opioids, sedating antihistamines) ; pregnancy risk (contraindicated) ; overdose treatment (Flumazenil – GABA receptor antagonist) ; benzodiazepine anxiolytics (Xanax, Valium, Ativan) ; monitoring labs (liver function, CBC with long-term use) . Non-Benzodiazepine Anxiolytics: Buspirone (Buspar) MOA (5HT1A partial agonist at pre- and post-synaptic receptors, does not affect GABA) ; enhanced serotonergic activity in amygdala, PFC, striatum, thalamus; side effects (lightheadedness, headache, insomnia, nausea, nervousness) ; adverse reactions (akathisia, serotonin syndrome) ; contraindications (panic attacks, severe hepatic/renal disease) . Hypnotics & Sleep Disorders: Medications for falling asleep (short half-life: Ramelteon, Rozerem, Sonata for middle insomnia) ; medications for staying asleep (Zolpidem ER, temazepam, Belsomra, eszopiclone/Lunesta) ; Zolpidem (Ambien) MOA (selective GABA a1 subunit agonist) ; Eszopiclone (Lunesta) MOA (a1 isoform selective agonist of GABA-A) ; Ramelteon (Rozerem) MOA (melatonin receptor agonist M1/M2, MT1/MT2) ; Suvorexant (Belsomra) MOA (dual orexin receptor antagonist) ; brain areas involved in sleep (pituitary gland, pineal gland/melatonin, suprachiasmatic nucleus, ventrolateral preoptic area, tuberomammillary nucleus) . Pain Management Medications: Pregabalin (Lyrica) – binds to open VSCC, used for fibromyalgia, neuropathic pain; Milnacipran (Savella) – SNRI, heavier on NET, treats fibromyalgia pain and cognitive symptoms (fibro-fog) ; Duloxetine (Cymbalta) – SNRI, inhibits SERT and NE reuptake; Amitriptyline (Elavil) – TCA, anticholinergic effects, requires baseline EKG; Duloxetine side effects (N/V/D, dry mouth, headache, constipation, sedation, sexual dysfunction, HTN) ; adverse effects (serotonin syndrome, life-threatening seizures, discontinuation syndrome) . Neurotransmitters Involved in Wakefulness: Histamine, dopamine, norepinephrine, acetylcholine, serotonin . Sleep/Wake Switch: Histamine from tuberomammillary nucleus (TMN) promotes wakefulness; GABA from ventrolateral preoptic area (VLPO) promotes sleep . Sample Questions Include : "What is the role of the amygdala in anxiety?" → Plays a role in fear response; remembers stimuli that lead to anxiety; increases efficiency of glutaminergic neurotransmission in lateral amygdala; strengthens fear conditioning at NMDA receptors "What is the response of the parabrachial nucleus to fear?" → Respiratory response: increased respiration, shortness of breath, asthma, sense of being smothered "What is the motor response of the periaqueductal gray to fear?" → Fight, flight, or freeze response "What type of fibers are activated by noxious mechanical, thermal, or chemical stimuli?" → C-fibers "How do benzodiazepines help with anxiety?" → Target GABA neurotransmission via positive allosteric modulation (PAM); bind to GABA-A receptors; increase frequency of chloride channel opening "What is the antidote for benzodiazepine overdose?" → Flumazenil (Romazicon) "What is the mechanism of action of Buspirone (Buspar)?" → 5HT1A partial agonist; does not affect GABA; enhances serotonergic activity in amygdala, PFC, striatum, and thalamus "Which medications are best for problems staying asleep?" → Zolpidem ER, temazepam, Belsomra, eszopiclone (Lunesta) "What is the mechanism of action of Pregabalin (Lyrica)?" → Binds to open voltage-sensitive calcium channels (VSCC) to stop pain receptors "What is the difference between allodynia and hyperalgesia?" → Allodynia: pain from a stimulus that does not normally provoke pain; Hyperalgesia: increased pain from a stimulus that normally provokes pain All questions include complete rationales based on current evidence-based practice, psychopharmacology standards, and Maryville University curriculum requirements .
