Chronic Kidney Disease Hesi Case Study

Chronic kidney disease HESI casestudy scenarios are a common focus for nursing students preparing for the HESI exit exam because they integrate pathophysiology, assessment, prioritization, and therapeutic communication into a single clinical picture. Understanding how to analyze a CKD case study not only boosts exam performance but also strengthens the clinical reasoning skills needed for real‑world patient care. Below is a detailed walk‑through of a typical chronic kidney disease HESI case study, complete with background information, assessment data, nursing diagnoses, planned interventions, and evaluation criteria that mirror the style of HESI questions.

Introduction to Chronic Kidney Disease in HESI Case Studies

Chronic kidney disease (CKD) is defined as a gradual loss of kidney function over months or years, often resulting from diabetes, hypertension, or glomerulonephritis. In HESI case studies, the patient usually presents with nonspecific symptoms such as fatigue, decreased urine output, or peripheral edema, prompting the student to recognize early signs of renal impairment. The case study format challenges learners to connect laboratory trends (e.g., rising serum creatinine, falling eGFR) with clinical manifestations and to prioritize nursing actions that slow disease progression, manage complications, and prepare the patient for possible renal replacement therapy.

Pathophysiology Relevant to the Case The kidneys maintain fluid, electrolyte, and acid‑base balance while excreting metabolic waste. In CKD, progressive nephron loss leads to:

• Reduced glomerular filtration rate (GFR) – causing accumulation of urea, creatinine, and potassium. * Impaired sodium and water excretion – resulting in volume overload, hypertension, and edema. * Disrupted erythropoietin production – leading to normocytic, normochromic anemia.
• Altered vitamin D activation – contributing to secondary hyperparathyroidism and renal osteodystrophy.
• Increased inflammatory cytokines – accelerating cardiovascular risk.

These pathophysiological shifts generate the assessment findings that appear in the HESI case study stem.

HESI Case Study Overview

Patient Profile

• Name: J.M., 58‑year‑old male
• Medical History: Type 2 diabetes mellitus (12 years), hypertension (10 years), hyperlipidemia
• Meds: Metformin 500 mg BID, Lisinopril 20 mg daily, Atorvastatin 40 mg HS
• Allergies: NKDA

Presenting Situation
J.M. reports increasing fatigue over the past 6 weeks, occasional shortness of breath on exertion, and noticeable swelling of his ankles and feet. He notes that his urine appears “foamy” and that he has needed to urinate less frequently. Vital signs on admission: BP 168/94 mm Hg, HR 92 bpm, RR 18/min, SpO₂ 96 % on room air, temperature 37.1 °C.

Laboratory Results

Subjective Data

• “I feel tired all the time and my legs feel heavy.”
• “I’ve been eating less because I don’t feel hungry.”
• “I notice my urine looks bubbly when I go to the bathroom.”

Objective Data

• Bilateral pitting edema 2+ up to mid‑calf.
• Auscultation: basilar crackles lungs, S₃ gallop.
• Skin: pallor, dryness.
• Neurologic: alert and oriented x3, mild difficulty concentrating.

Nursing Diagnoses (Prioritized)

1. Excess Fluid Volume related to decreased renal excretion as evidenced by hypertension, peripheral edema, basilar crackles, and elevated BUN/creatinine.
2. Decreased Cardiac Output related to fluid overload and anemia as evidenced by tachycardia, S₃ gallop, and low hemoglobin.
3. Activity Intolerance related to anemia and fatigue as evidenced by reports of tiredness and reduced endurance.
4. Imbalanced Nutrition: Less Than Body Requirements related to anorexia and dietary restrictions as evidenced by weight loss (if noted) and low serum albumin (if measured).
5. Risk for Electrolyte Imbalance (Hyperkalemia) related to reduced glomerular filtration as evidenced by serum K⁺ 5.6 mmol/L.
6. Knowledge Deficit regarding CKD management, dialysis options, and medication adherence as evidenced by patient statements about limited understanding of disease progression.

Planning and Interventions

Fluid Management

• Monitor daily weights, intake and output, and signs of pulmonary congestion.
• Restrict sodium to <2 g/day and fluid intake based on current volume status (often 1500‑2000 mL/day unless overt overload).
• Administer prescribed loop diuretic (e.g., furosemide 40 mg IV BID) and assess for effectiveness and ototoxicity.
• Educate patient on recognizing sudden weight gain (>2 lb in 24 h) as a sign of fluid retention. ### Anemia Correction
• Collaborate with provider to initiate erythropoiesis‑stimulating agent (ESA) therapy if hemoglobin remains <10 g/dL despite iron repletion.
• Provide oral or IV iron supplementation as indicated (check ferritin and TSAT).
• Encourage small, frequent meals high in protein and calories to support erythropoiesis.

Electrolyte Surveillance

• Check serum potassium q6‑8h initially, then daily once stable.
• Implement potassium

Electrolyte Surveillance

• Implement potassium-binding agents (e.g., sodium polystyrene sulfonate) as prescribed, and monitor for adverse effects.
• Restrict dietary potassium intake to <20 mEq/day, avoiding high-potassium foods like bananas, oranges, and potatoes.
• Administer calcium gluconate if hyperkalemia is severe or life-threatening, while awaiting definitive treatment.
• Educate the patient on the risks of hyperkalemia (e.g., cardiac arrhythmias) and the importance of adhering to dietary and medication regimens.

Knowledge Deficit

• Provide structured education on chronic kidney disease (CKD) progression, including the role of dialysis, medication adherence, and lifestyle modifications.
• Use teach-back methods to ensure understanding of instructions regarding fluid, diet, and medication management.
• Collaborate with a CKD educator or social worker to address barriers to care, such as financial constraints or lack of access to resources.
• Document patient understanding and adjust teaching strategies as needed to address gaps in knowledge.

Imbalanced Nutrition: Less Than Body Requirements

• Assess for signs of malnutrition (e.g., weight loss, low

Imbalanced Nutrition: Less Than Body Requirements

• Assess for signs of malnutrition (e.g., weight loss, low serum albumin, prealbumin, muscle wasting) weekly.
• Collaborate with a renal dietitian to develop an individualized meal plan optimizing protein intake (1.0-1.2 g/kg/day of high-quality protein) while managing phosphorus, potassium, and sodium.
• Administer phosphate binders with meals as prescribed if serum phosphorus is elevated.
• Consider oral nutritional supplements (e.g., renal-specific formulas) if oral intake is consistently inadequate.
• Monitor appetite, nausea, vomiting, and early satiety; prescribe antiemetics or appetite stimulants as needed.

Conclusion

This comprehensive nursing care plan addresses the complex needs of a patient with advanced Chronic Kidney Disease (CKD) presenting with fluid overload, anemia, hyperkalemia, knowledge deficits, and malnutrition. Interventions focus on meticulous monitoring, targeted pharmacological management (diuretics, ESAs, iron binders, potassium control agents), and stringent dietary modifications to mitigate immediate complications like pulmonary edema and cardiac arrhythmias. Crucially, the plan prioritizes patient education and empowerment, employing teach-back methods and collaboration with dietitians and social workers to address barriers and foster understanding of disease progression, dialysis options, and the critical importance of medication and regimen adherence. By systematically addressing fluid balance, electrolyte stability, anemia correction, nutritional support, and knowledge enhancement, the nurse plays a pivotal role in improving symptom management, slowing disease progression, reducing hospitalizations, and ultimately enhancing the patient's quality of life and readiness for potential renal replacement therapies. Ongoing reassessment and adaptation of the care plan are essential to meet the evolving needs of the patient throughout their CKD journey.
