The material thoroughly reviews delirium versus dementia (rapid onset vs insidious onset, level of consciousness differences), stages of Alzheimer’s disease (mild, moderate, severe), the four A’s of Alzheimer’s (agnosia, aphasia, amnesia, apraxia), and pharmacologic management including acetylcholinesterase inhibitors (Donepezil, Rivastigmine, Galantamine) and Memantine (NMDA receptor antagonist). It also explains neurotransmitter roles such as acetylcholine in memory and glutamate-related excitotoxicity. The exam content further addresses anorexia and bulimia (cardiac complications, electrolyte imbalances, refeeding precautions), paraphilic disorders, gender dysphoria, and therapeutic nurse–patient relationship strategies. Anxiety disorders are comprehensively covered, including GAD, panic disorder, PTSD (symptoms 1 month), OCD, social anxiety disorder, acute vs chronic anxiety, hyperarousal symptoms, and panic-level nursing priorities.
