Assignment brief
A 3rd-year nursing student is assigned to create a comprehensive nursing care plan for a 17-year-old female patient admitted to an inpatient psychiatric unit with a new diagnosis of Anorexia Nervosa, restricting type. The patient presents with significant weight loss (BMI 15.5 kg/m²), bradycardia (heart rate 48 bpm), and electrolyte imbalances (hypokalemia, hypophosphatemia). She expresses intense fear of gaining weight and distorted body image. The assignment requires the student to develop at least three distinct nursing diagnoses, prioritizing the most immediate physiological and psychological needs. For each diagnosis, the student must provide the appropriate NANDA-I label, related factors (etiology), and defining characteristics (signs and symptoms). The student should also identify at least two measurable patient outcomes (goals) and three nursing interventions with their rationales, referencing current evidence-based practice guidelines and scholarly literature. Focus on the diagnostic reasoning process and the justification for the chosen diagnoses and interventions.
Reference example
Nursing Diagnosis: Imbalanced Nutrition: Less Than Body Requirements
Patient Profile: A 17-year-old female admitted with Anorexia Nervosa, restricting type. BMI 15.5 kg/m², bradycardia (HR 48 bpm), hypokalemia, hypophosphatemia. Expresses intense fear of weight gain and distorted body image.
Nursing Diagnosis: Imbalanced Nutrition: Less Than Body Requirements related to insufficient food intake secondary to psychological distress, distorted body image, and fear of weight gain as evidenced by BMI of 15.5 kg/m², reported intentional restriction of food intake, and laboratory findings of hypokalemia and hypophosphatemia.
Defining Characteristics:
Objective: Body mass index (BMI) of 15.5 kg/m²; bradycardia (heart rate 48 bpm); laboratory values indicating hypokalemia (e.g., serum potassium 2.8 mEq/L) and hypophosphatemia (e.g., serum phosphorus 1.5 mg/dL); observed refusal to eat meals; significant weight loss from previous baseline.
Subjective: Patient verbalizes, "I don't need to eat," "I feel fat even though I'm losing weight," and expresses a desire to maintain a weight significantly below healthy parameters.
Related Factors:
Psychological distress associated with body image dissatisfaction and a pervasive fear of gaining weight.
Cognitive distortions regarding food, weight, and body shape.
Physiological factors contributing to appetite suppression or altered metabolism (though the primary driver is psychological).
Ritualistic behaviors surrounding food and eating.
Patient Outcomes (Goals):
Patient will demonstrate a gradual increase in caloric intake, consuming at least 75% of prescribed meals and snacks within 7 days.
Patient will achieve a weight gain of 0.5 to 1 lb per week, reaching a BMI of at least 17.0 kg/m² within 4 weeks.
Patient will verbalize a reduction in anxiety related to food intake and weight gain, reporting a decrease in fear from a 9/10 to a 5/10 on a subjective distress scale within 10 days.
Nursing Interventions and Rationales:
Establish a therapeutic milieu and structured eating schedule: Provide a safe, supportive environment free from food-related triggers. Implement a consistent meal and snack schedule (e.g., 3 meals and 3 snacks per day) to normalize eating patterns and provide regular opportunities for nutritional intake.
Rationale: A structured environment reduces anxiety and provides predictability, which is crucial for individuals with eating disorders. Regular, frequent meals help to re-establish a normal metabolic rate and prevent extreme hunger or fullness, which can trigger compensatory behaviors (NANDA International, 2021).
Monitor vital signs, weight, and intake/output closely: Assess vital signs (especially heart rate, blood pressure, temperature) and weigh the patient daily or as per protocol, using a standardized procedure (e.g., same time, same scale, after voiding, in hospital gown). Accurately document all food and fluid intake.
Rationale: Close monitoring is essential due to the significant physiological risks associated with malnutrition, including cardiac arrhythmias, electrolyte imbalances, and hypothermia. Weight monitoring provides objective data on nutritional status and response to interventions (Haber, 2020).
Provide nutritional counseling and education: Collaborate with a registered dietitian to develop a meal plan tailored to the patient's needs, gradually increasing caloric and nutritional content. Educate the patient about the importance of balanced nutrition for physical and mental health, addressing her specific fears and misconceptions in a non-confrontational manner.
Rationale: Nutritional rehabilitation is the cornerstone of treatment. Education helps the patient understand the physiological consequences of starvation and the benefits of adequate nutrition, fostering a more collaborative approach to recovery (APA, 2022).
Implement behavioral interventions: Utilize techniques such as supervised mealtimes, distraction therapy post-meal, and reinforcement of positive eating behaviors. Set clear limits on behaviors that interfere with eating (e.g., excessive exercise, purging).
Rationale: Behavioral strategies help to manage the complex psychological components of the eating disorder, reinforcing adaptive behaviors and discouraging maladaptive ones. Supervision ensures safety and accountability during meals (NANDA International, 2021).
Address electrolyte imbalances: Administer prescribed electrolyte replacements (e.g., potassium chloride, phosphate supplements) as ordered by the physician. Monitor serum electrolyte levels regularly.
Rationale: Severe malnutrition can lead to dangerous electrolyte disturbances that increase the risk of cardiac arrest. Prompt correction is vital for patient safety (Haber, 2020).

Nursing Diagnosis: Disturbed Body Image related to cognitive distortion and unmet psychological needs secondary to Anorexia Nervosa as evidenced by patient's persistent verbalization of feeling "fat" despite significant weight loss, refusal to look at her reflection, and preoccupation with body shape and weight.
Defining Characteristics:
Objective: Patient avoids mirrors and reflections; patient covers body with loose clothing; patient expresses disgust when discussing her body.
Subjective: Patient states, "I look disgusting," "My thighs are huge," "I can't stand seeing myself."
Related Factors:
Unmet psychological needs (e.g., need for control, self-esteem).
Sociocultural pressures regarding thinness.
Internalized societal standards of beauty.
Cognitive distortions regarding perception of body size and shape.
Patient Outcomes (Goals):
Patient will engage in at least one non-body-focused activity daily within 1 week.
Patient will verbalize at least one neutral or positive statement about her body or appearance within 2 weeks.
Patient will tolerate looking at her reflection for a brief period (e.g., 30 seconds) without significant distress within 3 weeks.
Nursing Interventions and Rationales:
Promote self-esteem through non-body-focused activities: Encourage participation in activities that do not emphasize appearance or weight, such as art therapy, music therapy, journaling, or group discussions on topics unrelated to food or body image.
Rationale: Shifting focus away from the body helps the patient develop a sense of self-worth independent of weight and shape, fostering a more balanced perspective (Haber, 2020).
Facilitate verbalization of feelings and concerns: Create opportunities for the patient to express her fears, anxieties, and negative thoughts about her body in a safe, non-judgmental environment. Use active listening and therapeutic communication techniques.
Rationale: Expressing emotions can help the patient process her distorted thoughts and begin to challenge them. Understanding the underlying unmet needs driving the body image disturbance is crucial for effective intervention (NANDA International, 2021).
Challenge cognitive distortions gradually: Gently question and explore the patient's negative self-perceptions. Encourage her to consider alternative perspectives and evidence that contradicts her distorted beliefs. Avoid direct confrontation, which can increase defensiveness.
Rationale: Cognitive restructuring is a key component of therapy for eating disorders. By challenging distortions, the nurse helps the patient develop a more realistic and accurate perception of her body (APA, 2022).
Encourage gradual exposure to body image: As tolerated, encourage the patient to look at herself in a mirror for short periods, starting with non-threatening views (e.g., seeing her hands or feet) and progressing to more challenging views. Provide support and reassurance during these exposures.
Rationale: Gradual exposure can help desensitize the patient to her fears and reduce the anxiety associated with confronting her body image. This process should be carefully managed to avoid overwhelming the patient (Haber, 2020).

Nursing Diagnosis: Risk for Electrolyte Imbalance
Nursing Diagnosis: Risk for Electrolyte Imbalance related to inadequate fluid and electrolyte intake, and potential purging behaviors (if present, though primary diagnosis is restricting type) secondary to malnutrition and altered metabolic state.
Risk Factors:
Insufficient intake of potassium, sodium, phosphorus, and other essential electrolytes due to severe food restriction.
Potential for vomiting or laxative abuse (even in restricting type, these can occur under stress).
Renal compensatory mechanisms attempting to conserve sodium and water, leading to altered electrolyte balance.
Cardiac effects of malnutrition, including altered membrane potentials.
Patient Outcomes (Goals):
Patient will maintain serum electrolyte levels within normal limits (e.g., potassium 3.5-5.0 mEq/L, phosphorus 2.5-4.5 mg/dL) throughout hospitalization.
Patient will demonstrate understanding of the risks associated with electrolyte imbalances by verbalizing at least two potential complications within 48 hours.
Nursing Interventions and Rationales:
Monitor laboratory values regularly: Closely monitor serum electrolytes (potassium, sodium, chloride, magnesium, phosphorus) as ordered by the physician, typically daily or more frequently during initial stabilization.
Rationale: Early detection of imbalances is critical for preventing life-threatening complications such as cardiac arrhythmias (Haber, 2020).
Administer electrolyte replacements as prescribed: Ensure timely and accurate administration of oral or intravenous electrolyte supplements as ordered. Monitor for adverse effects of refeeding, such as refeeding syndrome.
Rationale: Correcting deficiencies is paramount. Refeeding syndrome, a potentially fatal complication of nutritional rehabilitation, can cause rapid shifts in electrolytes, particularly phosphate, potassium, and magnesium (APA, 2022).
Encourage adequate fluid intake: Promote intake of fluids, balancing with the nutritional plan, to help maintain hydration and electrolyte balance, unless contraindicated.
Rationale: Proper hydration is essential for overall physiological function and helps prevent concentration of electrolytes (Haber, 2020).
Educate patient on signs and symptoms of electrolyte imbalance: Teach the patient to report symptoms such as muscle weakness, palpitations, dizziness, confusion, or nausea.
Rationale: Patient awareness and prompt reporting of symptoms can facilitate early intervention and prevent severe complications.

Understanding Nursing Diagnoses for Anorexia Nervosa
Anorexia Nervosa (AN) is a complex eating disorder characterized by persistent restriction of energy intake leading to significantly low body weight, an intense fear of gaining weight, and a disturbance in the way one's body weight or shape is experienced. Developing accurate nursing diagnoses is fundamental to providing effective, patient-centered care. These diagnoses guide the nursing process, from assessment and planning to intervention and evaluation. This section explores key nursing diagnoses relevant to AN, using a detailed example to illustrate the application of NANDA-I (North American Nursing Diagnosis Association International) terminology and diagnostic reasoning.
Core Components of a Nursing Diagnosis
A nursing diagnosis is a clinical judgment about individual, family, or community responses to actual or potential health problems/life processes. It typically includes three parts (or two for risk diagnoses):
Problem: The NANDA-I label that identifies the health problem (e.g., Imbalanced Nutrition: Less Than Body Requirements).
Etiology (Related Factors): The factors that contribute to or are associated with the problem (e.g., insufficient food intake, psychological distress).
Signs and Symptoms (Defining Characteristics): The objective and subjective data that provide evidence of the problem (e.g., low BMI, patient's verbalizations).
Analysis of the Example: Imbalanced Nutrition: Less Than Body Requirements
Structure and Components
The primary nursing diagnosis, 'Imbalanced Nutrition: Less Than Body Requirements,' is structured according to NANDA-I guidelines. The problem statement clearly identifies the core issue: nutritional deficit. The etiology, 'related to insufficient food intake secondary to psychological distress, distorted body image, and fear of weight gain,' precisely links the nutritional problem to its underlying psychological drivers, which is critical in AN. The defining characteristics are robust, encompassing both objective data (low BMI, bradycardia, lab values) and subjective data (patient's verbalizations), providing strong evidence for the diagnosis.
Thesis/Claim
The central claim is that the patient's nutritional status is compromised due to a complex interplay of psychological factors and behavioral patterns characteristic of Anorexia Nervosa. This diagnosis asserts that the physiological state (malnutrition) is a direct consequence of the psychological distress and cognitive distortions associated with the disorder. The inclusion of specific physiological indicators like bradycardia and electrolyte imbalances reinforces the severity and the immediate threat to the patient's physical well-being.
Evidence and Justification
The evidence presented is multi-faceted and compelling. Objective data, such as a BMI of 15.5 kg/m², bradycardia (HR 48 bpm), hypokalemia (2.8 mEq/L), and hypophosphatemia (1.5 mg/dL), are critical physiological indicators of severe malnutrition and its consequences. Subjective data, including the patient's statements ('I don't need to eat,' 'I feel fat'), directly reflect the distorted body image and fear of weight gain that fuel the disorder. The related factors are well-supported by the typical presentation of Anorexia Nervosa, as described in diagnostic manuals like the DSM-5-TR and clinical literature. The nursing interventions are directly linked to addressing these evidenced factors, aiming to correct the nutritional deficit while simultaneously tackling the underlying psychological issues.
Organization and Flow
The presentation of the nursing diagnoses follows a logical order of priority. 'Imbalanced Nutrition' is placed first due to its immediate life-threatening potential, followed by 'Disturbed Body Image,' which is a core psychological feature and a significant driver of the nutritional problem. 'Risk for Electrolyte Imbalance' is also a critical physiological concern, often intertwined with malnutrition and refeeding. Each diagnosis is clearly delineated with its components (defining characteristics, related factors/risk factors), patient outcomes, and nursing interventions with rationales. This structured format enhances clarity and facilitates understanding of the care plan.
Tone and Language
The tone is professional, objective, and clinical, appropriate for academic and professional nursing contexts. The language is precise, utilizing specific medical and nursing terminology (e.g., 'bradycardia,' 'hypokalemia,' 'cognitive distortions,' 'therapeutic milieu'). Contractions are avoided in the formal diagnosis and intervention descriptions, maintaining a formal academic style. The rationales for interventions are evidence-based, referencing authoritative sources like NANDA-I and clinical texts, which adds credibility and demonstrates a commitment to best practices.
Revision Opportunities and Considerations
While the example is strong, potential revisions could involve further specifying the 'related factors' for 'Disturbed Body Image' by linking them more directly to developmental stage or specific life events if known. For 'Risk for Electrolyte Imbalance,' explicitly mentioning the risk of 'refeeding syndrome' within the rationale for interventions would strengthen the emphasis on this critical complication. Additionally, incorporating patient-centered goals that reflect shared decision-making (e.g., 'Patient will collaborate with the dietitian to identify three preferred healthy foods within 1 week') could enhance the patient's engagement in their care plan. Ensuring all interventions are explicitly linked to specific, measurable outcomes is also a continuous area for refinement in care planning.
Example of a Risk Diagnosis: Risk for Electrolyte Imbalance
The diagnosis 'Risk for Electrolyte Imbalance' is crucial because the physiological consequences of starvation can manifest rapidly and severely. The risk factors listed (insufficient intake, potential purging, altered metabolic state) are directly linked to the pathophysiology of Anorexia Nervosa. The interventions focus on proactive monitoring (labs) and corrective measures (electrolyte replacement), alongside patient education. This highlights the preventative aspect of nursing care, aiming to avert a crisis before it occurs. The outcomes are focused on maintaining physiological stability (normal lab values) and patient awareness of potential dangers.

FAQs
What is the most critical nursing diagnosis for a patient with Anorexia Nervosa?
The most critical nursing diagnosis is often 'Imbalanced Nutrition: Less Than Body Requirements' due to the severe physiological consequences of starvation, including electrolyte imbalances, cardiac complications, and organ damage. 'Risk for Electrolyte Imbalance' and 'Risk for Refeeding Syndrome' are also critically important, especially during nutritional rehabilitation.
How do I differentiate between 'Imbalanced Nutrition: Less Than Body Requirements' and 'Deficient Knowledge' regarding nutrition in Anorexia Nervosa?
'Imbalanced Nutrition' focuses on the physiological deficit and the behavioral/psychological factors preventing adequate intake. 'Deficient Knowledge' relates to a lack of understanding about nutritional principles. While a patient with AN may have deficient knowledge, the core problem is the psychological resistance to eating and the resulting malnutrition, not simply a lack of information. The nursing diagnosis should reflect the primary issue driving the condition.
Can Anorexia Nervosa be diagnosed solely based on weight loss?
No. While significant weight loss and a low BMI are key indicators, Anorexia Nervosa is a complex psychiatric disorder. The diagnosis also requires the presence of intense fear of gaining weight, distorted body image, and significant self-evaluation based on weight and shape, as outlined in the DSM-5-TR. Nursing diagnoses should reflect this multifaceted nature.
What is 'Refeeding Syndrome' and why is it important for nursing diagnoses?
Refeeding syndrome is a potentially fatal complication that can occur when nutritional support is initiated for individuals who are severely malnourished. Rapid shifts in fluids and electrolytes (especially phosphate, potassium, and magnesium) can occur, leading to cardiac, respiratory, and neurological problems. Nursing diagnoses and interventions must proactively address the risk of refeeding syndrome, particularly during the initial stages of nutritional rehabilitation, through careful monitoring and gradual refeeding.
