Rn Adult Medical Surgical Chronic Kidney Disease

Chronic Kidney Disease (CKD) is a progressive condition where the kidneys gradually lose their function over time. As a registered nurse (RN) specializing in adult medical-surgical care, managing patients with CKD requires a comprehensive understanding of the disease, its complications, and the interventions aimed at slowing progression and improving quality of life. This article delves into the intricacies of CKD, focusing on the RN's role in assessment, intervention, and education within the medical-surgical setting.

Understanding Chronic Kidney Disease

Chronic Kidney Disease (CKD) is characterized by the gradual loss of kidney function over time. This progressive decline impacts the kidneys' ability to filter waste, regulate fluid and electrolyte balance, and produce hormones. CKD is classified into five stages based on the Glomerular Filtration Rate (GFR), a measure of kidney function:

• Stage 1: Kidney damage with normal or increased GFR (≥90 mL/min/1.73 m²)
• Stage 2: Kidney damage with mildly decreased GFR (60-89 mL/min/1.73 m²)
• Stage 3a: Moderately decreased GFR (45-59 mL/min/1.73 m²)
• Stage 3b: Moderately decreased GFR (30-44 mL/min/1.73 m²)
• Stage 4: Severely decreased GFR (15-29 mL/min/1.73 m²)
• Stage 5: Kidney failure (GFR <15 mL/min/1.73 m²) or requiring dialysis

Common causes of CKD include diabetes, hypertension, glomerulonephritis, polycystic kidney disease, and urinary tract obstructions. Early detection and management are crucial to slow the progression of CKD and prevent complications.

The RN's Role in Assessing CKD Patients

A thorough assessment is the foundation of nursing care for patients with CKD. As an RN in an adult medical-surgical setting, your assessment should include:

History and Physical Examination

• Medical History: Obtain a detailed history of present illness, including the duration and severity of CKD symptoms. Document co-morbidities such as diabetes, hypertension, heart failure, and peripheral vascular disease. Gather information about medications, allergies, and past surgeries.
• Medication Review: Review all medications, including prescription, over-the-counter, and herbal supplements. Pay particular attention to nephrotoxic drugs like NSAIDs and certain antibiotics. Assess for adherence to prescribed medications.
• Family History: Inquire about a family history of kidney disease, diabetes, or hypertension, as these can increase the risk of CKD.
• Social History: Assess lifestyle factors such as smoking, alcohol consumption, and dietary habits. Evaluate the patient's understanding of CKD and their ability to manage the condition.
• Physical Examination:
  • Vital Signs: Monitor blood pressure, heart rate, respiratory rate, and temperature. Hypertension is a common finding in CKD.
  • Fluid Status: Assess for signs of fluid overload, such as edema, jugular venous distension (JVD), and crackles in the lungs. Monitor daily weights and urine output.
  • Cardiovascular System: Auscultate heart sounds for murmurs or extra sounds. Palpate peripheral pulses to assess circulation.
  • Respiratory System: Assess respiratory effort and auscultate lung sounds for abnormalities.
  • Integumentary System: Inspect the skin for dryness, itching, and signs of uremic frost.
  • Neurological System: Evaluate mental status, including alertness, orientation, and cognitive function. Assess for signs of uremic encephalopathy, such as confusion, lethargy, and seizures.
  • Gastrointestinal System: Assess for nausea, vomiting, and loss of appetite. Inspect the abdomen for distension or tenderness.

Diagnostic and Laboratory Data

• Glomerular Filtration Rate (GFR): Monitor GFR trends to assess the stage and progression of CKD.
• Urine Analysis: Assess for proteinuria, hematuria, and urinary casts. Monitor urine albumin-to-creatinine ratio (UACR) to quantify proteinuria.
• Serum Creatinine and Blood Urea Nitrogen (BUN): Elevated levels indicate impaired kidney function. Monitor trends to assess disease progression.
• Electrolytes: Monitor sodium, potassium, calcium, phosphorus, and magnesium levels. Electrolyte imbalances are common in CKD and can lead to serious complications.
• Hemoglobin and Hematocrit: Assess for anemia, which is a common complication of CKD due to decreased erythropoietin production.
• Parathyroid Hormone (PTH): Monitor PTH levels to assess for secondary hyperparathyroidism, a common complication of CKD.
• Vitamin D Levels: Assess for vitamin D deficiency, which can contribute to secondary hyperparathyroidism and bone disease.
• Lipid Profile: Monitor cholesterol and triglyceride levels, as CKD patients are at increased risk for cardiovascular disease.
• Albumin: Monitor serum albumin levels, as hypoalbuminemia is common in CKD and can contribute to edema.

Nursing Interventions for CKD Patients

Based on the assessment findings, the RN implements targeted interventions to manage CKD and prevent complications. Key nursing interventions include:

Fluid Management

• Monitor Fluid Balance: Accurately record intake and output. Weigh patients daily to assess fluid status.
• Fluid Restriction: Implement fluid restrictions as prescribed by the physician. Educate patients and families about the rationale for fluid restriction and strategies for managing thirst.
• Diuretics: Administer diuretics as prescribed to manage fluid overload. Monitor electrolyte levels and blood pressure.

Electrolyte Management

• Potassium Management: Monitor potassium levels and implement strategies to prevent hyperkalemia. Restrict dietary potassium intake. Administer potassium-binding resins (e.g., sodium polystyrene sulfonate) as prescribed. Monitor ECG for signs of hyperkalemia.
• Phosphorus Management: Restrict dietary phosphorus intake. Administer phosphate binders (e.g., calcium acetate, sevelamer) with meals to reduce phosphorus absorption. Monitor calcium and PTH levels.
• Calcium Management: Monitor calcium levels and administer calcium supplements as prescribed. Manage secondary hyperparathyroidism with vitamin D analogs and calcimimetics.

Blood Pressure Management

• Antihypertensive Medications: Administer antihypertensive medications as prescribed, such as ACE inhibitors, ARBs, beta-blockers, and calcium channel blockers. Monitor blood pressure and adjust medications as needed.
• Lifestyle Modifications: Educate patients about lifestyle modifications to control blood pressure, such as reducing sodium intake, exercising regularly, and maintaining a healthy weight.

Anemia Management

Ethical Considerations

Caring for patients with chronic kidney disease involves several ethical considerations. RNs must ensure they are providing care that respects patient autonomy, beneficence, non-maleficence, and justice.

• Autonomy: Patients have the right to make informed decisions about their care. RNs must provide comprehensive information about treatment options, risks, and benefits, allowing patients to participate in shared decision-making. This includes respecting the patient's decision to accept or refuse treatment, including dialysis or kidney transplant.
• Beneficence: RNs are obligated to act in the best interest of their patients. This involves providing evidence-based care, promoting comfort, and maximizing quality of life. In the context of CKD, beneficence may include interventions to slow disease progression, manage symptoms, and prevent complications.
• Non-Maleficence: RNs must avoid causing harm to their patients. This includes carefully monitoring medications, preventing infections, and minimizing the risk of adverse events. In CKD care, this involves avoiding nephrotoxic medications and managing potential complications of treatment, such as hyperkalemia or fluid overload.
• Justice: RNs must ensure that all patients receive fair and equitable care, regardless of their socioeconomic status, race, ethnicity, or other factors. This involves advocating for access to affordable medications, dialysis services, and kidney transplantation. RNs should be aware of and address any disparities in CKD care within their communities.

End-of-Life Care

As CKD progresses to end-stage renal disease (ESRD), RNs may be involved in providing end-of-life care. This includes:

• Advance Care Planning: Facilitating discussions about advance directives, such as living wills and durable power of attorney for healthcare.
• Palliative Care: Providing palliative care to manage symptoms and improve quality of life for patients who are not candidates for or choose to forgo dialysis or kidney transplant.
• Hospice Care: Referring patients to hospice care when appropriate, to provide comfort and support during the final stages of life.

Conclusion

Managing patients with chronic kidney disease in an adult medical-surgical setting requires a comprehensive and multifaceted approach. As a registered nurse, your role encompasses assessment, intervention, education, and advocacy. By understanding the complexities of CKD, implementing evidence-based interventions, and providing compassionate care, you can significantly impact the lives of patients living with this chronic condition. Continuous professional development and staying abreast of the latest advances in CKD management are essential to provide the highest quality of care.
