NLE Psychiatric DisordersPersonality, Somatic, and Eating DisordersStudy Notes

Study notes for Personality, Somatic, and Eating Disorders that match the NLE 2026 syllabus. Built to mirror how Professional Regulation Commission (PRC) — Board of Nursing structures NLE Psychiatric Disorders questions, these notes walk through each concept with examples, formulas, and practice questions designed for time-pressured exam conditions.

Exam context

Professional Regulation Commission (PRC) — Board of Nursing runs the Philippine Nurse Licensure Examination (PNLE) on Bi-annual. Its Psychiatric Disorders section sits under a "Core" weighting, and Personality, Somatic, and Eating Disorders is the 4th chapter in the 7-chapter NLE Psychiatric Disorders rotation. The NLE passing mark is 75% weighted average with no sub-test below 60%, and the most recent 2026 paper drew about 50 questions from Psychiatric Disorders.

Personality, Somatic, and Eating Disorders - Study Notes

This comprehensive study guide addresses three interrelated groups of psychiatric disorders tested on the Philippine Nursing Licensure Examination (NLE): personality disorders, somatic symptom and related disorders, and eating disorders. These conditions share a common thread of maladaptive patterns affecting how clients relate to others, perceive their bodies, and control their behavior. As a registered nurse in the Philippines, you must understand these disorders within the context of the Mental Health Act (Republic Act No. 11036), which mandates humane, community-based, recovery-oriented mental health care that respects client rights and dignity. Eating disorders demand particular vigilance for life-threatening complications such as refeeding syndrome, making them among the most medically serious psychiatric conditions. Your role involves early detection, stabilization of medical complications, therapeutic limit-setting, and coordination with the interdisciplinary team to promote recovery.

Summary

Personality, somatic, and eating disorders represent three interconnected groups of psychiatric conditions characterized by maladaptive patterns of relating, perceiving the body, and controlling behavior. **Personality disorders** are organized into three clusters—Cluster A (odd/eccentric: paranoid, schizoid, schizotypal), Cluster B (dramatic/erratic: borderline, antisocial, histrionic, narcissistic), and Cluster C (anxious/fearful: avoidant, dependent, obsessive-compulsive)—and require consistent, firm limit-setting, team unity, and evidence-based therapies (particularly DBT for Borderline Personality Disorder). **Somatic symptom and related disorders** involve real physical symptoms or health anxiety that are not intentionally produced and require careful medical evaluation followed by recognition that symptoms are real, redirection from secondary gain, and helping clients recognize emotion-symptom connections. **Eating disorders** carry the highest mortality of any psychiatric illness and demand medical stabilization of life-threatening complications (electrolyte imbalances, cardiac dysrhythmias) before psychological intervention; refeeding syndrome is a critical complication requiring slow nutrition reintroduction and close electrolyte monitoring. Nursing care across all three groups emphasizes therapeutic relationships, professional boundaries, family education, and adherence to the Mental Health Act (RA 11036), which mandates humane, community-based, recovery-oriented care that respects client autonomy and dignity. Effective care integrates medical monitoring, structured behavioral interventions, psychotherapy, and compassionate limit-setting within an interdisciplinary team framework.

Sections

A personality disorder is defined as an enduring, pervasive, and inflexible pattern of inner experience and behavior that deviates markedly from the expectations of the individual's culture, begins by adolescence or early adulthood, is stable over time, and leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning. Clients with personality disorders typically have limited insight into their maladaptive patterns—they often do not recognize their behavior as problematic and instead blame others or external circumstances. This lack of insight significantly complicates treatment and is a key distinguishing feature from other mental health disorders. Personality disorders are organized into three clusters based on descriptive similarities: **CLUSTER A—Odd, Eccentric, or Suspicious Presentation:** - **Paranoid Personality Disorder:** Characterized by a pervasive pattern of distrust and suspiciousness of others' motives. Clients interpret neutral remarks as insulting or threatening, question the loyalty of friends, suspect hidden meanings, and bear grudges. They fear that information will be used against them and are reluctant to confide in others. Nursing approach requires consistency, honesty, transparency in communication, and respect for their need for distance while gently encouraging appropriate engagement. - **Schizoid Personality Disorder:** Marked by detachment from social relationships and a restricted range of emotional expression. These clients prefer to work alone, show little interest in close relationships, appear indifferent to praise or criticism, and have few, if any, close friends. They are not acutely distressed by their isolation as they genuinely prefer solitude. Nursing care should respect their need for distance while providing non-intrusive support. - **Schizotypal Personality Disorder:** Involves acute discomfort with close relationships, cognitive or perceptual distortions, and eccentric behavior. Clients may have odd beliefs (magical thinking), unusual perceptual experiences, excessive social anxiety, and suspicious thoughts. They struggle with social engagement but do desire close relationships, unlike schizoid clients. Nursing intervention emphasizes patience, concrete communication, and gentle reality orientation without confrontation. **CLUSTER B—Dramatic, Emotional, or Erratic Presentation:** - **Borderline Personality Disorder (BPD):** One of the most challenging and high-risk personality disorders in clinical practice. Core features include unstable and intense relationships (rapidly cycling between idealization and devaluation), unstable self-image, recurrent self-harm and suicidal behavior, chronic feelings of emptiness, intense fear of abandonment (real or imagined), affective instability (rapid mood shifts), and identity disturbance. A critical concept in BPD is **splitting**—the tendency to view others and situations in extremes (all good or all bad), with no middle ground. This explains the characteristic relationship volatility. Clients with BPD have the highest risk for non-lethal self-harm (up to 80% engage in deliberate self-injury) and approximately 8-10% die by suicide. Nursing management requires firm, consistent, clear limits enforced uniformly by the entire team to prevent manipulation and splitting. A unified team approach is essential—all staff must agree on the care plan to prevent clients from "playing staff against each other." Safety interventions must prioritize suicide and self-harm prevention. Dialectical Behavior Therapy (DBT), which combines cognitive-behavioral techniques with mindfulness and acceptance strategies, is the evidence-based gold standard for BPD, teaching distress tolerance, emotion regulation, interpersonal effectiveness, and mindfulness skills. - **Antisocial Personality Disorder:** Characterized by a pervasive pattern of violation of others' rights, beginning in childhood or early adolescence and continuing into adulthood. Features include deceitfulness, manipulation, impulsivity, irritability, aggression, failure to conform to social norms and laws, lack of remorse or guilt, and reckless disregard for self or others. These clients may engage in criminal behavior and show no genuine guilt or attempt at restitution. They are skilled manipulators who can charm and deceive. Nursing care emphasizes firm, consistent limits; holding clients accountable for behavior without being punitive; avoiding power struggles; and clear communication among the team to prevent division and exploitation. - **Histrionic Personality Disorder:** Defined by excessive emotionality and attention-seeking. Clients are often highly dramatic, use physical appearance to draw attention, speak theatrically with exaggeration, are easily influenced by others, and perceive relationships as more intimate than they are. They crave novelty and excitement and may become bored easily. Nursing approach uses calm, matter-of-fact responses that do not reward or amplify dramatic behavior while still validating feelings. - **Narcissistic Personality Disorder:** Characterized by a grandiose sense of self-importance, preoccupation with fantasies of unlimited success or power, belief in being special and unique, need for excessive admiration, sense of entitlement, interpersonally exploitative behavior, and lack of empathy for others. Unlike BPD clients, narcissistic clients do not fear abandonment; rather, they demand special treatment. Nursing care requires maintaining professionalism, setting clear boundaries, not engaging in power struggles, and avoiding feeding the client's need for admiration. **CLUSTER C—Anxious, Fearful, or Dependent Presentation:** - **Avoidant Personality Disorder:** Characterized by social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Clients avoid occupational activities involving interpersonal contact due to fear of criticism or rejection. They are preoccupied with being criticized or rejected in social situations and inhibited in new interpersonal situations because of feelings of inadequacy. Nursing intervention focuses on building confidence, providing positive feedback, and creating safe, non-threatening environments for gradual exposure to social engagement. - **Dependent Personality Disorder:** Marked by an excessive need to be taken care of, with submissive and clinging behavior. Clients have difficulty making everyday decisions without reassurance from others, need others to assume responsibility for major areas of their lives, fear abandonment, have difficulty expressing disagreement, have difficulty initiating projects or doing things independently, and go to great lengths to obtain support. Nursing management encourages independent decision-making, reduces caretaking that fosters dependence, and sets realistic, progressively challenging goals to build autonomy. - **Obsessive-Compulsive Personality Disorder (OCPD):** Distinct from Obsessive-Compulsive Disorder (OCD), OCPD involves preoccupation with orderliness, perfectionism, and control, at the expense of flexibility and efficiency. Clients are devoted to details and rules, show excessive devotion to productivity, are reluctant to delegate, have a restricted emotional expression, and are rigid in their thinking. Unlike OCD, clients with OCPD do not experience true obsessions and compulsions as intrusive or distressing. Nursing approach respects the client's need for order while gently encouraging flexibility and emotional expression. **General Principles of Nursing Management for All Personality Disorders:** - Establish and maintain clear, firm, consistent limits and boundaries that are enforced uniformly by all team members - Use a consistent structured approach with excellent interdisciplinary communication to prevent manipulation and splitting - Prioritize safety, particularly self-harm and suicidal behavior risk - Help clients recognize the impact of their behavior on others through feedback delivered without judgment - Avoid engaging in power struggles or punishment-based approaches - Support evidence-based therapies (particularly DBT for BPD, Cognitive-Behavioral Therapy for others) - Focus on skill-building and healthy coping rather than attempting to change personality traits - Recognize that personality change is slow and requires sustained effort

1. PERSONALITY DISORDERS: DEFINITION, CLUSTERS, AND CLINICAL CHARACTERISTICS

Examples

  • A client with Borderline Personality Disorder idealized their primary nurse for weeks, calling her 'the only one who truly understands,' but then devalued her dramatically after a minor perceived slight, stating 'you don't care about me at all.' This exemplifies splitting. The nursing response is to remain calm, professional, and consistent, ensuring the entire team maintains the same care plan and boundaries to prevent the client from manipulating staff into conflicting approaches.
  • A client with Antisocial Personality Disorder convinces one staff member that medication is causing terrible side effects while telling another staff member nothing is wrong, attempting to obtain medication changes. A unified team approach, where all staff communicate and maintain consistent positions, prevents this manipulation.
  • A client with Dependent Personality Disorder asks the nurse to make decisions about their daily activities (clothing, meals, schedule). Rather than simply deciding for them, the nurse might say: 'I can help you think through the options, but I believe you're capable of making this choice. What feels right to you?' This encourages autonomy.
  • A client with Avoidant Personality Disorder refuses to attend group therapy due to fear of being judged. The nurse might arrange for initial attendance of a smaller, safer group and provide positive feedback about their courage, gradually building confidence for larger groups.

Key Points

  • Personality disorders are ego-syntonic—clients do not recognize their behavior as problematic; this lack of insight complicates treatment
  • Three clusters organize personality disorders: Cluster A (odd/eccentric), Cluster B (dramatic/erratic), and Cluster C (anxious/fearful)
  • Borderline Personality Disorder involves splitting, intense fear of abandonment, self-harm, and suicidal behavior; requires firm limits and unified team approach
  • Antisocial Personality Disorder features manipulation, deceitfulness, lack of remorse, and violation of others' rights; requires clear accountability without punishment
  • Nursing care emphasizes consistency, clear communication among team members, safety prioritization, and skill-building through evidence-based therapies
  • Dialectical Behavior Therapy (DBT) is the gold standard for Borderline Personality Disorder

Somatic symptom and related disorders represent a fascinating intersection of genuine physical symptoms with psychological underpinnings. The hallmark feature is that **symptoms are real to the client and are not intentionally or consciously produced**—this distinction is critical and fundamentally different from malingering (faking for external gain) or factitious disorder (deliberately inducing symptoms). Clients are not "faking" in the colloquial sense; their distress is genuine, though the medical cause may be minimal or absent. **Key Disorders in This Category:** **Somatic Symptom Disorder:** Characterized by one or more distressing somatic symptoms accompanied by excessive thoughts, feelings, or behaviors related to those symptoms. The client devotes excessive time and energy to health concerns, experiences persistent and elevated anxiety about health, and may engage in excessive health-related behaviors (repeatedly checking the body for signs of illness, seeking reassurance) or excessive avoidance (avoiding medical care due to fear of hearing bad news). The physical symptoms may be specific and localized or diffuse and vague. The excessive cognitive and behavioral responses are often more impairing than the symptoms themselves. For example, a client with chest pain (which may or may not have a cardiac cause) becomes so focused on preventing a heart attack that they avoid any activity, social engagement, or work, leading to complete functional impairment. **Illness Anxiety Disorder (formerly Hypochondriasis):** Distinguished by preoccupation with having or acquiring a serious disease. Unlike somatic symptom disorder, the client has minimal or no somatic symptoms—the anxiety is about potentially getting sick or already being sick without evidence. The client engages in excessive health-related behaviors (frequent medical visits, extensive internet research about diseases, body checking) or excessive avoidance (avoiding medical care or situations where they might encounter illness). The difference from somatic symptom disorder is clear: somatic symptom disorder has prominent physical symptoms; illness anxiety disorder does not. **Conversion Disorder (Functional Neurological Symptom Disorder):** A fascinating condition involving neurological symptoms (such as paralysis, blindness, numbness, seizures, or aphonia—inability to speak) that are inconsistent with recognized neurological disease patterns. Neurological testing typically reveals no organic cause. Notably, some clients with conversion disorder demonstrate **"la belle indifférence"** (beautiful indifference)—a surprisingly calm or even cheerful attitude toward their seemingly serious neurological deficit, which contrasts sharply with the usual emotional response to genuine neurological loss. For example, a client paralyzed from the waist down might discuss their paralysis with apparent unconcern. This is thought to reflect the unconscious "gain" or relief the symptom provides (primary gain—reducing anxiety or intrapsychic conflict; secondary gain—receiving attention, avoiding responsibilities). However, not all clients with conversion disorder show la belle indifférence, so its absence does not rule out the diagnosis. **Factitious Disorder:** This is distinct from the above and involves the deliberate falsification, feigning, or induction of physical or psychological symptoms to assume the sick role. Unlike malingering, where symptoms are produced for external gain (avoiding work, obtaining compensation), factitious disorder is driven by psychological need to be sick. In severe cases, healthcare workers may deliberately induce symptoms in themselves or, in Factitious Disorder Imposed on Another (formerly Munchausen Syndrome by Proxy), in another person (such as a child). **Critical Nursing Principles for Somatic Symptom and Related Disorders:** 1. **Rule out genuine medical illness first:** These clients can also develop real medical conditions. A complete medical workup is essential before attributing symptoms to psychological causes. Dismissing symptoms without proper investigation can miss serious pathology and damage the therapeutic relationship. 2. **Acknowledge that symptoms are real to the client:** Even when no medical cause is found, the client's distress, pain, or physical sensation is genuine. Telling a client "it's all in your head" is counterproductive, invalidating, and damaging to the therapeutic relationship. This phrase is never appropriate. 3. **Avoid confrontation about the psychological nature of symptoms:** Directly confronting a client by saying "your symptoms are psychological" or "you're creating this yourself" typically leads to increased defensiveness, increased symptom reporting, and disruption of the therapeutic alliance. Instead, take a gentle, collaborative approach that gradually helps the client make connections between stress and symptoms. 4. **Limit secondary gain and attention to symptoms:** Excessive nursing attention focused on physical symptoms can inadvertently reinforce and maintain them. Conversely, a matter-of-fact, professional approach that acknowledges symptoms without excessive focus redirects the client's energy toward adaptive coping and functioning. For example, rather than spending 30 minutes discussing symptoms, the nurse might acknowledge them briefly ("I hear you're experiencing chest discomfort; that must be distressing") and then redirect to activities or skills: "Let's talk about what helps you feel calmer when you're anxious." 5. **Help the client recognize connections between emotions/stress and physical symptoms:** Over time, gently and collaboratively guide the client to notice patterns: "I noticed your headaches tend to happen after difficult conversations with your family. Have you noticed that too?" This promotes insight without blame. 6. **Teach adaptive coping and stress management:** Provide concrete skills in relaxation (deep breathing, progressive muscle relaxation), mindfulness, problem-solving, and healthy lifestyle (sleep, exercise, social engagement). These are more adaptive than focusing on symptoms. 7. **Maintain a consistent primary healthcare provider:** "Doctor-shopping" (seeing many providers seeking confirmation of disease) and repeated testing can reinforce health anxiety and the sick role. A consistent provider who knows the client's history and maintains appropriate limits is more effective. 8. **Coordinate with the interdisciplinary team:** Ensure all providers (physicians, mental health providers, nurses) maintain consistent messaging and avoid reinforcing the sick role through excessive testing or symptom-focused visits. **Nursing Diagnoses Commonly Associated with These Disorders:** - Ineffective coping (related to anxiety about health) - Anxiety (related to health preoccupation) - Social isolation (related to symptom focus and avoidance) - Self-care deficit (related to excessive avoidance or symptom preoccupation) - Impaired role performance (related to excessive symptom focus) - Powerlessness (related to feeling unable to control symptoms) **Prioritization Under Maslow's Hierarchy:** Most clients with somatic symptom disorders present with safety and belongingness needs as priorities. Physical safety (ruling out medical illness) is first; however, once medical causes are ruled out, the focus shifts to addressing the anxiety, isolation, and loss of function. Self-actualization through adaptive coping and engagement in meaningful activities becomes important.

2. SOMATIC SYMPTOM AND RELATED DISORDERS: MIND-BODY CONNECTIONS AND NURSING IMPLICATIONS

Examples

  • A 45-year-old client presents to the clinic with multiple somatic complaints: fatigue, diffuse pain, gastrointestinal distress, and cognitive complaints. Extensive workup finds no specific medical cause. Rather than dismissing the client, the nurse acknowledges: 'I see you're experiencing significant distress from these symptoms. While the tests didn't identify a specific disease, your discomfort is real. Let's explore what's happening in your life right now and develop strategies to help you feel better.' The nurse then learns the client's daughter has been ill, causing significant worry. Through gentle exploration, the client begins to recognize that stress increases symptoms.
  • A client with Illness Anxiety Disorder spends hours daily researching diseases online and makes frequent medical appointments seeking reassurance. The nurse works with the healthcare team to establish a plan: scheduled appointments at regular intervals (not as-needed), consistent messaging that reassurance-seeking maintains anxiety, teaching of mindfulness and reality-testing (rather than symptom checking), and gradually redirecting toward activities and social engagement.
  • A client with Conversion Disorder presents with sudden paralysis of the left leg following a stressful argument with a supervisor. Neurological testing is normal. The nurse avoids confrontation ('your symptoms are psychological') but instead collaborates: 'It sounds like you've been under a lot of stress at work. Let's talk about what you're experiencing and explore ways to help you feel better.' Over time, as stress is addressed and the client engages in physical therapy (presented as 'helping you regain function'), the paralysis gradually resolves.
  • A 68-year-old client with long-standing somatic symptom disorder presents with new chest discomfort. The nurse ensures a full cardiac workup is performed (EKG, troponins, stress test) because this client can develop real cardiac disease. Once cardiac causes are ruled out, the nurse uses the established approach of acknowledging symptoms, limiting focus on them, and redirecting toward coping and functioning.

Key Points

  • Somatic symptom and related disorders feature real symptoms that are NOT intentionally produced; clients are not malingering
  • Three main categories: Somatic Symptom Disorder (prominent symptoms with excessive health focus), Illness Anxiety Disorder (health preoccupation with minimal symptoms), Conversion Disorder (neurological symptoms inconsistent with medical disease; may show la belle indifférence)
  • Factitious disorder is distinct and involves deliberate symptom production for psychological need to assume sick role
  • Nursing approach: rule out medical illness, acknowledge symptoms as real, limit secondary gain, help identify emotion-symptom connections, teach adaptive coping
  • Never tell a client 'it's all in your head' or confront them about psychological causes of symptoms
  • Consistent primary provider and team coordination prevent excessive testing and reinforcement of the sick role

Eating disorders represent severe disturbances in eating behavior and related thoughts and emotions, characterized by persistent eating patterns and associated behaviors that significantly impair physical health or psychosocial functioning. These disorders have the **highest mortality rate of any psychiatric illness**—approximately 5-20% mortality rate, primarily from medical complications and suicide. The majority of affected individuals are adolescents and young adults, though prevalence in males is increasing. Eating disorders are fundamentally about **control, self-worth, and body image**—not simply about food. Understanding this psychological foundation is essential for effective nursing care. **ANOREXIA NERVOSA** **Definition and Clinical Presentation:** Anorexia nervosa is characterized by three essential features: (1) restriction of energy intake leading to significantly low body weight (below what is minimally normal for age, sex, and height); (2) intense fear of gaining weight or becoming fat, even though the client is underweight; and (3) disturbance in the way one's body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of current low body weight. Clients are typically perfectionistic, have strong needs for control, and may have obsessive-compulsive traits. Two subtypes exist: **restricting type** (weight loss achieved through dieting and/or excessive exercise) and **binge-eating/purging type** (regular episodes of binge eating or purging behavior). **Physical Assessment Findings (Reflect Starvation):** - **Amenorrhea:** Loss of menstruation (one or more missed cycles) due to severe caloric restriction and low body fat - **Cardiovascular:** Bradycardia (slow heart rate, often 40-50 bpm or lower), hypotension (low blood pressure), and orthostatic changes - **Thermoregulation:** Hypothermia (low body temperature) - **Integumentary:** Dry, brittle skin; dry, thinning hair; lanugo (fine, downy body hair that develops as the body attempts to maintain warmth with loss of subcutaneous fat) - **Electrolyte disturbances:** Hypokalemia (low potassium), hyponatremia (low sodium), hypochloremia (low chloride), hypophosphatemia (particularly important in refeeding); these can cause cardiac arrhythmias - **Metabolic:** Elevated BUN and creatinine (from dehydration), elevated liver enzymes, low albumin (nutritional marker) - **Hematologic:** Anemia, thrombocytopenia (low platelets), leukopenia (low white cells) - **Skeletal:** Osteoporosis and increased fracture risk from prolonged inadequate nutrition and estrogen deficiency - **Gastrointestinal:** Constipation, delayed gastric emptying, abdominal distension **Severe Medical Complications:** - **Cardiac dysrhythmias:** The most life-threatening complication; can occur suddenly and cause sudden cardiac death even in seemingly stable clients - **Cardiac failure:** From severe electrolyte disturbances and malnutrition - **Electrolyte emergencies:** Severe hypokalemia, hypomagnesemia, hypophosphatemia - **Organ damage:** Renal dysfunction, liver dysfunction, pancreatic insufficiency - **Neurological:** Seizures (from electrolyte imbalance), cognitive impairment - **Death:** From cardiac complications, electrolyte disturbances, infections, or suicide **BULIMIA NERVOSA** **Definition and Clinical Presentation:** Bulimia nervosa is characterized by recurrent episodes of binge eating (eating large amounts of food with a sense of loss of control) followed by compensatory behaviors to prevent weight gain. Compensatory behaviors include self-induced vomiting, misuse of laxatives or diuretics, fasting, and/or excessive exercise. The binge eating and compensatory behaviors occur at least once per week for three months. A crucial distinction: **clients with bulimia are typically of normal weight or slightly overweight**, which makes the disorder less visually obvious than anorexia and can delay diagnosis. Clients typically feel shame, guilt, and disgust after binge-purge episodes, often hiding the behavior from others. **Physical Assessment Findings (Largely from Purging):** - **Dental:** Enamel erosion and caries (cavities) from exposure to gastric acid during vomiting; the client's teeth appear worn and translucent - **Oral:** Russell's sign—calluses, scarring, or cuts on the knuckles and back of hands from friction against teeth during self-induced vomiting - **Facial:** Parotid gland swelling (from repeated vomiting), puffy face (from fluid retention or electrolyte imbalance) - **Gastrointestinal:** Esophagitis, esophageal tears or perforation (potentially fatal), gastric dilation, rectal bleeding - **Electrolyte disturbances:** **Hypokalemia and metabolic alkalosis** (from loss of stomach acid and potassium through vomiting); these cause cardiac arrhythmias - **Cardiovascular:** Cardiac arrhythmias (from electrolyte loss), palpitations - **Metabolic:** Elevated amylase (from repeated vomiting) - **Gastrointestinal:** Constipation (from laxative abuse), abdominal pain **REFEEDING SYNDROME: A CRITICAL COMPLICATION** **What It Is:** Refeeding syndrome is a dangerous, potentially fatal metabolic shift that occurs when nutrition is reintroduced too rapidly to a severely malnourished client. It is most common in anorexia nervosa but can occur in any severely undernourished state (malignancy, starvation, prolonged fasting). The mechanism is profound: as the body shifts from catabolism (breaking down) to anabolism (building up), insulin levels surge. Insulin drives electrolytes—**particularly phosphate (phosphorus), potassium, and magnesium**—into cells for ATP synthesis and new cellular protein synthesis. This creates a state of **intracellular sufficiency with extracellular deficiency**, meaning blood levels drop dangerously low even though total body stores are depleted. **Hallmark Finding:** **Hypophosphatemia** is the hallmark of refeeding syndrome. Phosphate is critical for cellular energy (ATP), oxygen transport (2,3-DPG), and muscle function. Severe hypophosphatemia causes: - Rhabdomyolysis (muscle breakdown) - Respiratory muscle weakness (leading to respiratory failure) - Impaired myocardial contractility (heart failure) - Seizures - Altered mental status - Death **Associated Electrolyte Disturbances:** - **Hypokalemia:** Cardiac arrhythmias, muscle weakness - **Hypomagnesemia:** Cardiac arrhythmias, seizures, personality changes - **Hypocalcemia:** Tetany, seizures - **Fluid overload:** From sodium retention and insulin-driven fluid movement into cells, leading to pulmonary edema and heart failure **Clinical Presentation:** Refeeding syndrome typically emerges within the first week of nutritional reintroduction. Signs include respiratory distress, cardiac arrhythmias, weakness, confusion, seizures, and heart failure. Because symptoms overlap with other complications and can develop rapidly, prevention is critical. **Prevention and Nursing Management of Refeeding Syndrome:** 1. **Start nutrition slowly:** Initial caloric intake should be modest (typically 1,200-1,500 kcal/day), with slow advancement by 200-400 kcal every few days as tolerated 2. **Monitor electrolytes closely:** Baseline and frequent monitoring (daily to every 2-3 days initially) of phosphate, potassium, magnesium, and calcium 3. **Aggressive supplementation:** Replace electrolytes PRN based on lab values; phosphate replacement may require IV administration 4. **Monitor cardiac rhythm:** Continuous cardiac monitoring in severe cases; EKG monitoring for arrhythmias 5. **Monitor fluid balance:** Daily weights (same time, same scale, same clothing), intake and output, physical assessment for edema or signs of fluid overload 6. **Thiamine and multivitamin supplementation:** Prevent Wernicke encephalopathy (thiamine deficiency) 7. **Monitor closely for complications:** Watch for signs of heart failure, respiratory compromise, muscle weakness, altered mental status **GENERAL NURSING MANAGEMENT OF EATING DISORDERS** **Phase 1: Medical Stabilization (Life-Threatening Complications First)** This is the priority when clients present in acute crisis. Approach Maslow's hierarchy: physical safety is first. - Address severe electrolyte imbalances (potassium, phosphate, magnesium) through IV replacement if needed - Correct fluid balance and address dehydration - Monitor cardiac rhythm continuously for arrhythmias - Assess and stabilize respiratory status - Treat hypoglycemia if present - Consider involuntary hospitalization if the client is refusing care and medically unstable (under RA 11036 provisions for psychiatric emergency) - Involve physician, nutritionist, psychiatrist, and nursing team **Phase 2: Nutritional Rehabilitation** - **Establish a structured eating plan** with specific caloric goals, meal times, and food choices - **Observe during and for approximately one hour after meals** to prevent purging (hiding food, self-induced vomiting) or other avoidance behaviors. This is critical in bulimia nervosa. - **Monitor weight consistently:** same scale, same time (typically early morning after voiding), same type of clothing (or paper gown); weigh at least 2-3 times per week, more frequently if unstable - **Document intake and output carefully** - **Monitor electrolytes:** at least weekly initially during active refeeding; phosphate, potassium, magnesium are critical - **Advance calories gradually:** typically by 200-400 kcal every few days as tolerated; avoid rapid increases that precipitate refeeding syndrome - **Use a matter-of-fact, non-punitive approach:** avoid power struggles over food, which reinforce the client's sense of control and can worsen the disorder - **Engage the client collaboratively:** help them set realistic weight goals (not rapid weight loss, which is unhealthy, but steady, modest gain) - **Ensure nutritionist involvement:** plan appropriate, balanced meals **Phase 3: Psychological and Behavioral Intervention** - **Cognitive-Behavioral Therapy (CBT):** Evidence-based first-line treatment for eating disorders, addressing distorted thoughts about body image and weight, teaching adaptive coping - **Address distorted body image:** use evidence-based techniques (e.g., mirror exposure, confronting irrational thoughts) - **Build self-esteem and self-worth:** Help the client develop identity and self-concept beyond appearance and weight - **Teach healthy coping:** stress management, emotion regulation, interpersonal skills, problem-solving - **Family involvement:** particularly crucial for adolescents; Family-Based Therapy (FBT) is evidence-based for adolescent anorexia nervosa, empowering parents to help the child restore healthy eating - **Address underlying issues:** trauma, anxiety, depression, perfectionism, control issues - **Prevent relapse:** develop relapse prevention plan, teach early warning signs **Psychopharmacology:** - **Antidepressants (SSRIs such as fluoxetine):** Helpful for comorbid depression and anxiety; evidence strongest for bulimia nervosa in reducing binge-purge episodes - **Bupropion (Wellbutrin):** **CONTRAINDICATED in eating disorders**, particularly bulimia nervosa, because it **lowers the seizure threshold**, and electrolyte imbalances (especially hypokalemia from purging) increase seizure risk; the combination is dangerous - Antipsychotics and anxiolytics: may be used for co-occurring symptoms - No medication is a cure; psychotherapy is essential **Nursing Diagnoses and Interventions Under NANDA Framework:** 1. **Imbalanced nutrition: Less than body requirements** (Anorexia Nervosa) - Provide structured meal plan; supervise meals - Monitor weight and electrolytes - Provide nutritional counseling 2. **Risk for injury** (Electrolyte imbalance, cardiac dysrhythmia) - Monitor electrolytes closely - Continuous cardiac monitoring if indicated - Assess for signs of complications 3. **Disturbed body image** - Use CBT techniques; mirror work - Address distorted thoughts - Build alternative identity and self-worth 4. **Risk for self-harm** (in BPD co-occurring or severe eating disorder) - Assess for suicidal/self-harm ideation - Safety planning - Supervision if needed 5. **Ineffective coping** (related to perfectionism, control needs) - Teach healthy coping strategies - Stress management and relaxation - Problem-solving training 6. **Social isolation** (related to shame, body preoccupation) - Encourage social engagement - Address shame and stigma - Family involvement **Discharge Planning and Relapse Prevention:** - Establish outpatient follow-up: psychiatry, therapy (CBT), nutrition, primary care - Educate client and family on relapse warning signs (preoccupation with weight, food restriction, excessive exercise, body checking, purging) - Provide crisis resources: hotline numbers, crisis team contact - Connect to support groups (e.g., National Eating Disorders Association) - Follow-up at 1 week, then ongoing **Special Considerations in Philippine Healthcare Context (RA 11036):** Under the Mental Health Act, eating disorders qualify as serious mental health conditions requiring humane, community-based, recovery-oriented care. Involuntary hospitalization is permitted if the client is in acute medical danger (severe electrolyte imbalance, cardiac dysrhythmia, weight below critical threshold). Care must respect the client's dignity and right to self-determination while ensuring medical safety. Community mental health centers and barangay health workers play roles in ongoing support and relapse prevention.

3. EATING DISORDERS: ASSESSMENT, COMPLICATIONS, AND LIFE-THREATENING CARE CONSIDERATIONS

Examples

  • A 19-year-old female with anorexia nervosa (restricting type) is admitted with a weight of 38 kg (BMI 15.4; normal is 18.5-24.9). Labs show K+ 2.8 (normal 3.5-5.0), Mg 1.4 (normal 1.7-2.2), PO4 2.0 (normal 2.5-4.5), Ca 7.2 (normal 8.5-10.2). EKG shows prolonged QT interval. She denies the seriousness of her condition and does not want treatment. Medical stabilization is initiated: IV potassium repletion, IV magnesium, IV phosphate, continuous cardiac monitoring. Once medically stable (K+ > 3.0, cardiac arrhythmias resolve), a structured eating plan begins at 1,500 kcal/day with advance by 200 kcal every 3-4 days as tolerated. Nurse observes meals and supervises for 1 hour afterward. Daily weights are obtained. Labs are monitored every 2-3 days. Therapy begins, addressing perfectionism and need for control. Family is involved.
  • A 24-year-old male with bulimia nervosa presents with frequent binge-purge episodes (3-4 times daily), dental erosion, Russell's sign, and lab findings of K+ 3.2, HCO3- 32 (metabolic alkalosis). He feels shame and depression. A structured meal plan of 3 meals + 3 snacks (totaling 2,000-2,200 kcal) is established. Nurse observes during meals and for 1 hour afterward; the client sits in a supervised area where purging is visible and discouraged. Electrolytes are monitored and replaced. Fluoxetine is initiated for depression and to help reduce binge-purge frequency. CBT addresses distorted thoughts about body and weight, teaches emotion regulation, and helps identify triggers. Family therapy addresses family dynamics that may contribute.
  • A 16-year-old female with anorexia nervosa weighing 35 kg is admitted for medical stabilization. On day 3 of refeeding at 1,800 kcal/day, she develops sudden dyspnea, palpitations, and anxiety. Stat labs show PO4 1.2 (severe), K+ 2.5, Mg 1.3, Ca 6.8. EKG shows ST changes and prolonged QT. Clinical diagnosis: refeeding syndrome. IV phosphate, potassium, and magnesium are rapidly administered; caloric intake is reduced back to 1,200 kcal/day and advanced more slowly; cardiac monitoring continues. This scenario illustrates why slow refeeding and close electrolyte monitoring are critical.
  • A 45-year-old female with long-standing bulimia nervosa presents with esophageal discomfort after a binge-purge episode. Endoscopy reveals esophageal tears (from forceful vomiting) and mucosal erosion. She is hospitalized, NPO (nothing by mouth), on IV fluids and nutritional support while the esophagus heals. This demonstrates a severe purging-related complication. Treatment includes acid-blocking medication, careful reintroduction of food, therapy, and family support to address relapse risk.

Key Points

  • Eating disorders have the highest mortality rate of any psychiatric illness; medical complications (cardiac, electrolyte) are life-threatening
  • Anorexia nervosa: restriction → low weight, intense fear of weight gain, distorted body image; findings include amenorrhea, bradycardia, hypothermia, lanugo, electrolyte imbalance, osteoporosis
  • Bulimia nervosa: binge-purge pattern, typically normal weight; findings include hypokalemia/metabolic alkalosis, dental erosion, Russell's sign, parotid swelling, cardiac arrhythmias
  • Refeeding syndrome: rapid nutrition reintroduction → insulin surge → electrolytes driven into cells → severe hypophosphatemia (hallmark), hypokalemia, hypomagnesemia → cardiac/respiratory failure, seizures, death
  • Prevention of refeeding syndrome: start nutrition slowly, monitor electrolytes (especially phosphate) closely, supplement aggressively, monitor cardiac rhythm and fluid balance
  • Nursing management prioritizes medical stabilization first, then structured eating plan with observation during and after meals, slow caloric advancement, weight monitoring with same conditions, electrolyte monitoring, CBT, family involvement, and relapse prevention
  • Antidepressants (fluoxetine) help bulimia; bupropion is contraindicated due to seizure threshold lowering with electrolyte imbalance
  • Observe eating-disorder clients for approximately 1 hour after meals to prevent purging
  • Use matter-of-fact, non-punitive approach; avoid power struggles over food

Effective nursing care for personality, somatic, and eating disorders extends beyond the clinical setting into patient and family education, professional boundaries, and adherence to Philippine mental health law. The Mental Health Act (Republic Act No. 11036) establishes a framework for humane, community-based, recovery-oriented mental health care that protects client rights while ensuring safety. **PATIENT AND FAMILY EDUCATION** **For Personality Disorders:** - Educate families about the **chronic, relapsing nature** of personality disorders; change is slow and requires sustained effort - Teach the value of **consistent, structured limit-setting** without punishment; explain that clear boundaries actually create safety and therapeutic opportunity - Explain the concept of **splitting** in Borderline Personality Disorder and how to prevent it: "We all agree on the same plan so he doesn't feel he can divide and conquer us" - Teach families about **warning signs of suicide and self-harm**, especially in Borderline Personality Disorder (up to 8-10% die by suicide, up to 80% engage in non-lethal self-injury) - Emphasize the importance of **not withdrawing support** when the client devalues or tests boundaries; consistency is the therapeutic agent - Provide psychoeducation about therapy (particularly DBT for BPD), explaining that **therapy is harder than hospitalization** and requires active participation - Teach families to maintain their own mental health and set boundaries to prevent caregiver burnout - Explain that **limit-setting is not punishment**; it is therapeutic **For Somatic Symptom and Related Disorders:** - Educate families that **symptoms are real to the client, not fabrication**; teach them not to dismiss or minimize - Guide families to avoid **reinforcing the sick role**—excessive attention to symptoms, repeated reassurance-seeking, enabling avoidance of activities - Explain that **reassurance is temporary** and actually maintains anxiety in the long term; instead, families should redirect toward healthy coping and activity - Teach families not to engage in "hunting" for medical causes; trust the healthcare team's evaluation - Provide stress management techniques families can model - Explain that **psychological intervention is not dismissing the client**; rather, it addresses the underlying emotional and behavioral patterns maintaining the symptoms **For Eating Disorders:** - Educate families about the **seriousness and high mortality** of eating disorders; this is not vanity or willfulness - Teach families about **relapse warning signs**: preoccupation with weight, food restriction, excessive exercise, body checking, purging, social withdrawal - Explain **refeeding syndrome** in simple terms: "The body has been starving, so we have to reintroduce food very slowly. If we feed too fast, the minerals go into the cells and blood levels drop dangerously, causing heart and breathing problems" - Teach families **not to fight over food**; power struggles reinforce the eating disorder. Instead, provide the structured meal plan and step back from the emotional battle - For adolescents, explain **Family-Based Therapy (FBT)**: parents play an active role in helping the teenager restore normal eating; this is evidence-based and effective - Teach families about **medications that help** (fluoxetine for bulimia) and that **bupropion is dangerous** in eating disorders - Connect families to support resources: National Eating Disorders Association (NEDA) in Philippine context, support groups, mental health services **PROFESSIONAL BOUNDARIES AND PREVENTING BURNOUT** These disorders can evoke strong emotional responses in healthcare providers—frustration with personality disorders' apparent lack of insight, pity and over-involvement with somatic disorders, or despair about eating disorders' severity. Setting professional boundaries is essential: - **Maintain a consistent, professional relationship** that is warm but boundaried; friendly does not mean friendship - **Do not take behavior personally**; recognize that splitting, manipulation, and testing of boundaries are symptoms, not personal attacks - **Debrief with colleagues and supervisors** after difficult interactions; this prevents isolation and burnout - **Participate in team meetings and communication** to maintain a unified approach; divided staff are vulnerable to splitting and manipulation - **Know your limits**: if a particular client or disorder evokes strong emotional responses, discuss with a supervisor or consider reassignment - **Model healthy coping**: practice stress management, maintain boundaries with clients and family, take care of your own mental health - **Recognize secondary trauma** in eating disorder care: seeing young people suffering with body hatred can be emotionally taxing **LEGAL AND ETHICAL CONSIDERATIONS UNDER RA 11036** **Republic Act No. 11036 (Mental Health Act) Overview:** The Mental Health Act mandates that mental health care in the Philippines is humane, community-based, recovery-oriented, and respectful of human rights. Key provisions include: 1. **Client Rights:** - Right to receive mental health services with respect for human dignity and autonomy - Right to information about diagnosis, treatment, and prognosis in understandable language - Right to refuse treatment except in emergency situations - Right to confidentiality and privacy - Right to a designated mental health professional - Right to family/support system involvement (unless client objects) - Right to community-based care whenever possible - Right to appeal involuntary admission or treatment decisions 2. **Involuntary Admission:** Permitted only when a client is in acute psychiatric crisis or presents serious danger to self or others and refuses voluntary treatment. This requires assessment by authorized mental health professionals and involves legal safeguards. 3. **Commitment to Community-Based Care:** Hospitals should facilitate discharge and transition to community mental health centers, barangay health stations, and support services to prevent institutionalization. 4. **Prohibited Practices:** - Restraint and seclusion only as last resort in truly dangerous situations, with documentation - No psychiatric abuse or discrimination - No unnecessary medication or over-medication - No discrimination based on mental health status 5. **Confidentiality:** Information shared by the client is confidential, except when there is imminent danger to self or others (duty to warn) or suspected child/elder abuse. **Application to Each Disorder Group:** **Personality Disorders:** - Clients with Antisocial Personality Disorder may try to manipulate staff into rule violations; clear limits and documentation protect both client and staff - Involuntary admission may be appropriate if a client in a Borderline Personality Disorder crisis presents suicidal behavior and refuses help - Consistent team documentation of observations and care is essential to prevent staff manipulation and splitting **Somatic Symptom and Related Disorders:** - Clients have the right to refuse testing; however, reassurance that "nothing is wrong" does not serve them; gentle exploration of emotion-symptom connections respects autonomy while promoting insight - Continued testing "to prove there's nothing wrong" is ineffective and expensive; collaborative decision-making shifts this pattern **Eating Disorders:** - Involuntary hospitalization is justified when a client is medically unstable (severe electrolyte imbalance, cardiac dysrhythmia, weight dangerously low [BMI <12-13], unable to tolerate oral intake) and refuses care - Family involvement is vital, especially for adolescents; however, the client's right to privacy and voice is maintained within family therapy - Advance directives (e.g., specifying preferences for treatment if hospitalization becomes necessary) can be developed during stable periods - Respect for autonomy and recovery-orientation means moving toward community-based, outpatient therapy as soon as medically safe **CULTURAL COMPETENCE AND SPECIAL POPULATIONS** **Filipino Cultural Considerations:** - **Family-centredness (pakikipagkapwa):** Mental health care in the Filipino context is often family-centered. Family members expect involvement and may be essential to recovery. However, balance family involvement with client privacy and autonomy. - **Stigma:** Mental health conditions, particularly eating disorders and somatic complaints, carry significant stigma in some Filipino communities. Education and normalization are important. - **Barangay health workers:** In many areas, mental health care begins with barangay health systems; coordination between hospitals and community health workers is essential - **Religious and spiritual factors:** Faith is often central in Filipino recovery; respect religious practices and involve spiritual counselors if the client wishes - **Gender roles:** Cultural expectations about female body image and role may interact with eating disorder development; explore these gently - **Language:** Use appropriate language level; if the client speaks primarily Tagalog/Pilipino, ensure materials and education are provided in that language **Rising Prevalence in Males:** Historically, eating disorders were considered female-predominant; however, males now represent 15-25% of eating disorder cases. Males often present later (delayed diagnosis), may focus more on muscularity ("bigorexia") than thinness, and may hide binge-eating and purging more effectively. Screening should not be sex-based; all adolescents and young adults should be assessed for eating disorders. **LGBTQ+ Considerations:** Individuals who identify as LGBTQ+ may have higher rates of eating disorders and body dissatisfaction, potentially related to discrimination and body image pressure. Affirming, non-discriminatory care is essential; use client's preferred pronouns; ensure supportive environment.

4. PATIENT AND FAMILY EDUCATION, PROFESSIONAL BOUNDARIES, AND LEGAL CONSIDERATIONS UNDER RA 11036

Examples

  • A nurse educates the family of a 22-year-old with Borderline Personality Disorder: 'Your son idealizes me one day and says I don't care about him the next. This is called splitting—he's viewing situations and people in black and white. If some staff say 'yes' to a request and others say 'no,' he feels this is proof of inconsistency and may become more distressed. When you all agree on the same plan, even when he disagrees or tests you, you're helping him learn that consistency is trustworthy. It's harder than giving in, but it's what helps him heal.' The family commits to a unified approach.
  • A nurse educates the family of a client with somatic symptom disorder: 'When your mother says her back hurts and you immediately suggest she rest, get her ice, adjust pillows, and offer medication, you're showing love. But this can accidentally reinforce the pain focus. Instead, you might say: "I hear your back hurts; that sounds frustrating. Should we take a walk together?" You're acknowledging without over-focusing. Over time, this redirects her energy toward activity and coping. It's not about ignoring her; it's about not reinforcing the sick role.' The family learns this subtle distinction.
  • A nurse educates a family with a 17-year-old with anorexia nervosa: 'Eating disorders are very serious; your daughter's heart is at risk. That said, the more you fight with her about eating, the more control and power the eating disorder has. Your job is not to convince her to eat; that's the treatment team's job. Your job is to provide the structured meals the nutritionist recommends, step back from the emotional battle, and maintain your relationship. Family therapy will help you navigate this.' The family reframes their role from food police to supportive presence.
  • A nurse documents careful observations of a client with Borderline Personality Disorder: 'Client stated to primary nurse: "You're the only one who really cares; the other nurses don't understand." Client stated to nursing assistant: "I don't trust those nurses; they don't do anything for me." Clear documentation of these statements and the reminder to client of the team's unified plan prevents splitting and protects the client and staff. At team meeting, all staff are aligned: 'We all care and follow the same plan.' Client is redirected to see the consistency.

Key Points

  • Patient and family education emphasizes the chronic, relapsing nature of these disorders and the need for consistent, patient approaches
  • For Borderline Personality Disorder, educate families about splitting and why a unified team approach prevents manipulation and is therapeutic
  • For somatic disorders, educate families not to reinforce the sick role and to recognize that reassurance-seeking maintains anxiety long-term
  • For eating disorders, families need to understand seriousness and mortality, relapse warning signs, refeeding syndrome risk, and to avoid food-centered power struggles
  • Professional boundaries, team communication, and debriefing prevent staff burnout and splitting in personality disorders
  • RA 11036 protects client rights: dignity, autonomy, confidentiality, and community-based care; involuntary admission only in acute crisis with danger
  • Culturally competent care in Philippine context respects family-centeredness, addresses stigma, involves barangay health systems, and respects religious/spiritual factors
  • Eating disorders affect males increasingly; screening should not be sex-based; rising bigorexia (muscularity focus) in males warrants attention
  • LGBTQ+ individuals need affirming, non-discriminatory care with attention to higher eating disorder and body dissatisfaction risk
