What is Nephrotic Syndrome?
Nephrotic syndrome is altered kidney function from increased glomerular basement membrane permeability to plasma protein (albumin). The leak produces the classic picture: gross proteinuria, generalized edema (anasarca), hypoalbuminemia, oliguria, and hyperlipidemia.
It is classified by etiology or by the histologic change in the glomerulus, and it takes three forms: primary minimal change nephrotic syndrome (MCNS), secondary nephrotic syndrome, and congenital nephrotic syndrome. MCNS is the idiopathic type and the most common, accounting for 80% of cases. It can hit at any age but usually starts in the preschool years and shows up more in boys than girls. Secondary nephrotic syndrome follows systemic disease. Congenital nephrotic syndrome (CNS) comes from a rare autosomal recessive gene on the long arm of chromosome 19; its prognosis has improved with early protein and nutritional support, continuous cycling peritoneal dialysis (CCPD), and renal transplantation. MCNS usually does well, but relapses are common and most children respond to treatment.
Nursing Care Plans and Management
Care planning centers on relieving edema, supporting nutrition, conserving energy, preventing infection and relapse, and getting the family solid on medication and diet compliance.
Nursing Problem Priorities
- Management of edema and fluid balance
- Monitoring and maintenance of nutritional status
- Prevention and management of infection
- Administration and monitoring of prescribed medications
- Assessment and management of complications (e.g., thrombosis, hyperlipidemia)
- Regular monitoring of renal function and laboratory values
- Patient and family education
Nursing Assessment
Assess for the following subjective and objective data:
- Edema in the face, hands, feet, or legs
- Proteinuria producing frothy or foamy urine
- Hypoalbuminemia
- Hyperlipidemia
- Weight gain from fluid retention
- Fatigue and generalized weakness
- Loss of appetite
- Increased susceptibility to infection
- Abdominal pain or discomfort
- Thrombosis in severe cases
Assess for factors related to the cause:
- Decreased kidney function
- Fluid accumulation
- Inability to ingest, digest, or absorb nutrients
- Inadequate secondary defenses
Nursing Diagnosis
Build the nursing diagnoses from your assessment and the patient's priorities. The labels matter less than the clinical judgment behind them.
Nursing Goals
Goals and expected outcomes may include:
- The child's edema will decrease.
- The child will reach ideal body weight without excess fluid.
- The client will eat a nutritionally balanced diet.
- The child will alternate activity with rest.
- The parents will verbalize the cause and treatment of the illness.
- The child's temperature will stay <99°F.
- The child's breath sounds will be clear bilaterally.
- The child's urine will be clear without foul odor.
Nursing Interventions and Actions
1. Managing Fluid Volume and Hypervolemia
Lost protein means lost oncotic pull, so fluid leaks into tissue. Edema, weight gain, and fluid overload are what you are managing.
Weigh the child daily on the same scale, same time, same clothing. Daily weight is your best hydration marker. A gain over 0.5 kg/day means fluid retention.
Strictly monitor and record intake and output. This is how you track fluid balance.
Identify other sources of excess fluid (food, medications). Catching hidden sources keeps the regimen on track.
Limit fluid intake as ordered. Allowed intake is set by weight, urine output, and response to treatment.
Administer corticosteroids (e.g., prednisone), immunosuppressive agents, and diuretics as prescribed. See Pharmacologic Management
Provide frequent oral hygiene. Reduces dryness of the mouth and mucous membranes.
Teach parents dipstick urine testing and collection, and have them log results. Tracking urine protein shows the severity of the loss.
Teach parents about kidney function and the disease. Understanding the condition lets them follow through on the regimen.
2. Promoting Optimal Nutritional Balance
Urinary protein loss can drop total body protein, driving muscle wasting and weight loss. Watch protein and calorie intake and adjust the diet to match.
Assess nutritional patterns: food preferences, caloric intake, diet history. These shape the meal plan.
Encourage a high-potassium, low-fat, low-sodium diet with moderate protein. Potassium offsets potassium-wasting diuretics; low sodium limits fluid retention; protein compensates for urinary loss.
Make mealtimes comfortable and pleasant. Reduces factors that kill appetite.
Offer six small nutrient-dense meals rather than three large ones. Smaller meals cut the feeling of fullness and the stimulus to vomit.
Do not schedule medications right before meals. Pre-meal dosing produces fullness that worsens anorexia.
Refer to a dietitian. A dietitian sets daily nutrient requirements and methods for support.
3. Promoting Infection Control and Minimizing Risk for Infection
These children lose immunoglobulins in the urine and are on immunosuppressants, so they catch respiratory and urinary infections easily. Hand hygiene, respiratory precautions, and prophylactic antibiotics are your defense.
Assess for fever, respiratory changes (dyspnea, productive yellow sputum), urinary changes (cloudy, foul-smelling urine), and skin changes (tenderness, redness, swelling). Steroid and immunosuppressant therapy raises infection risk; catch it early to prevent relapse.
Maintain and teach aseptic technique and handwashing. Frontline prevention.
Keep the child warm and regulate room temperature and humidity. Avoids chilling and upper respiratory infection.
Use a private room or pair with non-infectious children. Protects from transmission.
Administer antibiotic therapy as ordered. Prevents or treats infection per culture and sensitivity. See Pharmacologic Management
Have parents and child avoid people with active infections. Limits exposure.
Tell parents to notify the physician immediately at any sign of infection. Allows prompt intervention before relapse.
4. Managing Fatigue and Energy Balance
Disease, protein loss, and muscle wasting all drain energy. Find the driver (anemia, electrolyte imbalance) and pace activity around it.
Assess fatigue, weakness, degree of edema, and difficulty moving in bed. Severe edema keeps the child still and prone.
Plan activity and watch behavior afterward. Builds endurance without overdoing it; disease, steroids, and inactivity cause mood swings and irritability.
Reinforce bed rest during the acute stage. Prevents energy expenditure when edema is severe.
Offer chosen play as tolerated, with rest periods. Provides stimulation within tolerance as edema resolves.
Allow quiet play and let the child set their own limits. Promotes independence and control.
Have the child rest when exhausted. Conserves energy.
Tell parents and child full activity returns as the disease resolves. Sets the expectation of recovery.
5. Initiating Health Teachings and Patient Education
Families need the disease process, diet, medication regimen, and warning signs cold. Solid teaching is what keeps them compliant and catches relapse early.
Assess knowledge of the disease, relapse signs, diet, activity, medications and side effects, and urine and vital sign monitoring. Identifies teaching needs for followup care.
Assess anxiety and need for help caring for the child. Anxiety blocks learning.
Teach parents and child the cause and expected treatment. Encourage questions. Gives them what they need to manage the condition.
Tell parents immunizations may be delayed. Protects an immunocompromised child.
Teach that steroids and immunosuppressants must be tapered, never stopped abruptly. Abrupt withdrawal causes complications.
Teach that relapse is possible and infection can trigger it. Drives the point on prevention.
Have parents return-demonstrate dipstick testing for albumin, edema checks, daily weights, and blood pressure, and report any weight gain or albumin in the urine immediately. Catches relapse early.
Praise parents and child as they build skills. Reinforcement keeps them engaged.
Reinforce physician orders on sodium restriction and activity progression. Supports a return to normal living.
Explain the disease may relapse with remissions and exacerbations and may require repeat hospitalization. Reinforces why compliance matters.
6. Administering Medications and Pharmacologic Support
Corticosteroids are the backbone of treatment; they cut inflammation and suppress the immune response to reduce proteinuria. Immunosuppressants, ACE inhibitors or ARBs, diuretics, and anticoagulants get added based on the patient.
Corticosteroids (e.g., prednisone) First-line. They reduce inflammation, suppress immunity, cut proteinuria, and often bring remission. Continue until urine is protein-free and stays normal for 10 days to 2 weeks; therapeutic response usually comes in 1 to 3 weeks.
Immunosuppressive agents (e.g., cyclophosphamide, mycophenolate mofetil) For steroid-resistant or steroid-dependent disease. They modulate immunity and reduce proteinuria, often paired with corticosteroids to control disease and prevent relapse.
Diuretics (e.g., furosemide) Address edema and fluid retention by increasing urine output and reducing overload.
Frequently Asked Questions
What is nephrotic syndrome? Nephrotic syndrome is a glomerular problem in which the basement membrane becomes leaky to albumin. Protein pours into the urine (proteinuria), blood albumin falls, and that single defect drives the rest of the picture: edema, low blood protein, and high cholesterol. In children, minimal change disease is the most common cause (NIDDK).
Why does the swelling (edema) happen? When albumin is lost in the urine, blood protein levels fall. Low protein in the blood lets water move out of the vessels into the tissues, collecting in the face, legs, arms, and abdomen. Severe, generalized swelling is called anasarca.
What is the first-line treatment? Corticosteroids such as prednisone are the backbone of treatment. They reduce inflammation, suppress the immune response, cut proteinuria, and often bring remission. Most children with minimal change disease respond, and therapy usually continues until the urine is protein-free and stays normal for 10 days to 2 weeks (NIDDK, National Kidney Foundation).
What is added when steroids are not enough? For steroid-resistant or steroid-dependent disease, immunosuppressants such as cyclophosphamide or mycophenolate mofetil are added. Diuretics like furosemide treat edema and fluid overload, and ACE inhibitors or ARBs and anticoagulants may be used based on the patient.
What should parents monitor at home? Teach parents to dipstick the urine for albumin, check for edema, take daily weights, and monitor blood pressure. They should report any weight gain or albumin in the urine right away, since these catch a relapse early.
Does nephrotic syndrome come back? Yes. It often follows a relapsing course with remissions and exacerbations and may require repeat hospitalization. Reinforcing why adherence to medication, sodium restriction, and monitoring matters helps families manage the long course.
