1. Delirium vs. Dementia: The Critical Distinction The most heavily tested concept is differentiating these two conditions. Delirium is an acute, rapid-onset syndrome characterized by an impaired, fluctuating level of consciousness. It is a temporary, reversible condition caused by underlying physiological issues like infections, drug toxicity, withdrawal, or metabolic imbalances. Dementia is a gr...

Disruptive behavior disorders involve an inability to regulate emotions and behaviors, resulting in persistent anger, hostility, and aggression. Mastering this material requires distinguishing the three primary diagnoses: Oppositional Defiant Disorder (ODD), Intermittent Explosive Disorder (IED), and Conduct Disorder (CD). 1. Oppositional Defiant Disorder (ODD) Core Feature: An enduring pattern of...

1. Attention-Deficit/Hyperactivity Disorder (ADHD) Diagnosis: A persistent pattern of inattention, hyperactivity, and impulsivity impacting academic and social life. It affects 9% of school-aged children, and symptoms persist into adulthood for 60% of cases. Females often present with less noticeable inattentive behaviors and are diagnosed later. Expected Findings: Short attention span, high distr...

1. Core Pathophysiology Somatic illnesses revolve around somatization : unconsciously transferring mental stress into actual bodily symptoms. The most critical concept is that clients genuinely experience these symptoms ; they are not faking it. Symptoms lack an organic basis, are driven by psychological conflicts, and are completely outside conscious control. Clients often suffer from alexithymia...

SUD is a chronic, progressive illness characterized by remissions and relapses. The highest-yield concepts for safe nursing care revolve around recognizing life-threatening withdrawal, overdose management, administering essential medications, and addressing maladaptive family dynamics. 1. Must-Know Substances & Safety Risks Alcohol: A central nervous system depressant. Alcohol withdrawal is li...

1. Major Depressive Disorder (MDD) Core Concept: Requires ≥2 weeks of sad mood or anhedonia + ≥4 symptoms (weight/sleep changes, fatigue, guilt, poor concentration, suicidal thoughts). Priority Nursing: Directly assess suicide risk (plan, lethality, access). Promote ADLs by breaking tasks into small, concrete steps. Avoid being overly cheerful; use silence and active listening to build trust. Medi...

1. Core Concept & Presentation Schizophrenia alters thought, perception, and behavior. It stems from genetic and neurochemical imbalances, primarily excess dopamine and serotonin. • Positive Symptoms: Additions to normal behavior, including delusions (fixed false beliefs), hallucinations (false sensory perceptions), and disordered speech like word salad or echolalia. • Negative Symptoms: Defic...

1. Medication Name and Class Haloperidol (Haldol) is a high-potency first-generation (conventional) antipsychotic structurally related to droperidol. 2. Mechanism of Action Haloperidol blocks central postsynaptic dopamine (D-2) receptors in the mesolimbic pathway, which treats positive symptoms of schizophrenia like hallucinations and delusions. However, dopamine blockade in the nigrostriatal path...

Chlorpromazine (Thorazine): Essential Clinical Profile 1. Mechanism of Action & Pharmacology Chlorpromazine is a first-generation phenothiazine antipsychotic and antiemetic. It blocks postsynaptic dopamine D2 receptors in the mesolimbic system, reducing psychosis but causing extrapyramidal symptoms (EPS). Dopamine blockade in the chemoreceptor trigger zone produces antiemetic effects. It exhib...

Medication Name/Class Generic/Brand: Fluphenazine / Prolixin Decanoate Class: First-Generation Antipsychotic (Phenothiazine) 2. Mechanism of Action Blocks postsynaptic D2 (dopamine) receptors in the mesolimbic system. Possesses weak anticholinergic and alpha1-adrenergic blocking effects. Strong D2 blockade reduces psychosis but directly causes extrapyramidal symptoms (EPS). 3. Expected Action/Ther...

1. Medication Name/Class Trilafon (perphenazine). Class: First-Generation Antipsychotic (FGA); Phenothiazine Antiemetic. 2. Mechanism of Action Blocks postsynaptic dopamine D2 receptors in the mesolimbic system (reducing psychosis) and the chemoreceptor trigger zone (stopping emesis). It also causes alpha-1 adrenergic and moderate anticholinergic blockade. 3. Expected Action/Therapeutic Effect Dec...

1. Medication Name/Class Generic/Brand: Ziprasidone (Geodon). Class: Atypical Antipsychotic, Serotonin-Dopamine Antagonist (SDA). 2. Mechanism of Action Antagonizes dopamine D2 and serotonin 5-HT2A receptors. Modulating mesolimbic dopamine reduces positive symptoms; mesocortical serotonin modulation targets negative symptoms. 3. Expected Action/Therapeutic Effect Reduces positive and negative psyc...

Aripiprazole Overview & Mechanism of Action Aripiprazole is an atypical antipsychotic acting as a partial agonist at dopaminergic D2 and serotonergic 5-HT1A receptors, and an antagonist at 5-HT2A receptors. This unique mechanism stabilizes dopamine, limiting extrapyramidal side effects compared to older agents. It is FDA-approved for schizophrenia, bipolar I disorder, major depressive disorder...

Core Concepts Personality disorders (PDs) are enduring, ingrained, maladaptive patterns of behavior and relating to others that severely impair functioning. Diagnosed only after age 18, traits are inflexible, making treatment slow and difficult. Patients rarely recognize their behavior as problematic, often blaming external circumstances. The 3 Diagnostic Clusters Cluster A (Odd/Eccentric): Parano...

Zyprexa (Olanzapine) 80/20 Summary 1. Mechanism & Profile Zyprexa is an atypical antipsychotic used for major psychiatric conditions. Its efficacy stems from dopamine (D1-D4) and serotonin (5-HT2A) receptor antagonism, modulating central activity to treat positive and negative schizophrenia symptoms. It binds 5-HT2C receptors (regulating food intake), explaining notable weight gain. Binding to...

Core Overview & Mechanism Risperidone is an atypical antipsychotic, classified as a serotonin-dopamine antagonist. Its primary efficacy arises from blocking dopamine D2 receptors, which targets the positive symptoms of schizophrenia, and blocking serotonin 5-HT2A receptors, which improves negative symptoms while lowering the risk of extrapyramidal symptoms (EPS) compared to conventional antips...

Core Profile and Mechanism Venlafaxine is an oral Serotonin Norepinephrine Reuptake Inhibitor (SNRI) indicated for adult major depressive disorder, generalized anxiety disorder, social anxiety, and panic disorder. It functions by inhibiting the central reuptake of serotonin and norepinephrine, possessing a 30-fold higher affinity for serotonin compared to norepinephrine. The drug is primarily meta...

Paroxetine: Core Clinical Profile (80/20 Summary) 1. Fundamental Overview & Warnings Paroxetine is an oral selective serotonin reuptake inhibitor (SSRI). It carries a severe Boxed Warning for increasing the risk of suicidal thoughts and behaviors in children, adolescents, and young adults (under 24 years old). It is not FDA-approved for pediatric patients, and chronic use may cause pediatric g...

Overview & Mechanism Sertraline is an oral selective serotonin reuptake inhibitor (SSRI) primarily indicated for major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, posttraumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD). Its therapeutic effect results from selective serotonin reuptake blockade at the neuronal membra...

Core Disorders & Distinctions Anorexia Nervosa (AN): Characterized by severe restriction of nutritional intake, extreme fear of weight gain, and severely distorted body image. Clients fail to recognize the illness, have an early onset (ages 14-18), and are significantly underweight. Subtypes include restricting (fasting/exercising) and binge-eating/purging. Bulimia Nervosa (BN): Involves recur...

1. Diagnosis & Core Concepts Obsessive-Compulsive Disorder (OCD) features two main components: Obsessions: Recurrent, persistent, intrusive, and unwanted thoughts, images, or impulses that cause marked anxiety. Compulsions: Repetitive, ritualistic behaviors (e.g., handwashing, checking, counting, ordering) or mental acts performed to neutralize the anxiety. The Core Problem: Patients know thes...

1. The Four Levels of Anxiety & Priorities Identifying the anxiety level dictates the correct nursing intervention. Mild: Senses sharpen; learning capacity increases. Action: This is the optimal time for client teaching. Moderate: Perceptual field narrows, but the client follows direction with assistance. Action: Use short, simple sentences and redirect the client to the task. Severe: Problem-...
