Nephrotic Syndrome in Children nursing care: what to assess and what to do first

The clinical picture

Nephrotic syndrome in children is most often minimal change disease, a glomerular condition that lets protein leak freely into the urine. The defining triad is heavy proteinuria, hypoalbuminaemia and generalised oedema, usually in a child between two and six years old who was otherwise well days before.

The oedema does not arrive evenly. Parents almost always describe periorbital oedema first thing in the morning, the eyes looking puffy on waking, which then eases through the day as the child is upright and fluid redistributes. By afternoon the same child may show ankle or scrotal or labial swelling instead, and by the time oedema is visible round the abdomen as ascites, the disease has usually been active for several days.

Urine often looks frothy from the protein content, and the child may have gained several kilograms of weight in fluid alone before anyone suspects a renal cause. Blood pressure is usually normal or only mildly raised, which distinguishes the presentation from nephritic syndromes.

Assessment: what to look for and in what order

Start the shift by asking a parent whether the child's eyes were puffy on waking that morning. It is the single most reliable early marker they will have noticed themselves, and asking for it directly gets a faster answer than asking generally about swelling.

Weigh the child at the same time each day, on the same scale, in the same clothing weight. Daily weight is the most sensitive indicator of fluid status in nephrotic syndrome and will change before oedema is visibly worse or better.

Measure abdominal girth if ascites is present, and track it alongside weight. Check for periorbital oedema, then move systematically down the body to scrotal or labial swelling, ankle oedema and any pleural effusion signs such as reduced breath sounds at the bases.

Dip the urine for protein each void if ordered, and send a first morning specimen for protein-to-creatinine ratio. Take blood pressure every shift, and watch for signs of hypovolaemia — cool peripheries, tachycardia, delayed capillary refill — which can coexist with total body fluid overload because so much fluid has shifted out of the vascular space.

Immediate interventions

Start strict intake and output, including nappy weights in a younger child, and record it hourly if the child is acutely unwell. Fluid restriction is used selectively rather than routinely, and is guided by the treating team based on the degree of oedema and serum sodium, not applied automatically to every admission.

Begin corticosteroid therapy as prescribed, typically oral prednisolone, and give it with food to reduce gastric irritation. Do not give diuretics without a specific order — in a child who is intravascularly depleted despite visible oedema, a diuretic can worsen hypovolaemia and precipitate acute kidney injury.

Screen for infection at admission and treat any identified source promptly. Children with nephrotic syndrome lose immunoglobulins in the urine alongside albumin, so they are functionally immunosuppressed and at real risk of spontaneous bacterial peritonitis and cellulitis, on top of whatever immunosuppression the steroids add later.

Ongoing nursing management

Continue daily weights and urine protein dipsticks until proteinuria clears, which is usually within two to three weeks of starting steroids in minimal change disease. Chart the trend, not just the daily number, so the team can see the direction of response.

Protect oedematous skin. Periorbital and scrotal tissue in particular can break down under prolonged swelling, so reposition regularly, keep skin dry, and elevate oedematous limbs where practical.

Monitor for steroid side effects across the admission and beyond: mood change, increased appetite, hypertension and hyperglycaemia. Keep the child away from anyone with an active infection, including staff and visiting siblings with a cold, given the combined effect of urinary immunoglobulin loss and steroid immunosuppression.

Reassess for relapse risk at every follow-up. Relapse is common in this condition and is defined by protein reappearing in the urine, so ongoing nursing contact after discharge matters as much as the inpatient stay.

Patient and family education

Teach the family to dip the child's urine at home each morning using reagent strips, and to keep a simple log of the result alongside the child's weight. Explain that a positive dip after a period of clear results is the earliest sign of relapse and should prompt a call to the team, not a wait-and-see approach.

Explain the puffy-eyes pattern directly: tell parents this is often the first thing they will notice again if the disease relapses, so they know what they are watching for rather than waiting for more obvious swelling.

Cover infection precautions in plain terms — avoiding known chickenpox contacts while on high-dose steroids, reporting fever promptly, and completing any recommended vaccination catch-up once the child is in remission and steroid dose has been reduced, following the treating team's specific timing.

How this appears on the NCLEX

NCLEX items on nephrotic syndrome in children usually test whether the candidate recognises the classic presentation and picks the correct first nursing action. A question stem describing a preschool-age child with morning eye puffiness and frothy urine is testing recognition of minimal change disease, not a nephritic process, so answers involving hypertension emergencies or gross haematuria as the primary finding are usually distractors.

Expect priority-setting items: daily weight and strict intake and output are commonly the correct first nursing action over less specific choices like general skin care. Questions may also test the diuretic trap — selecting to withhold or clarify a diuretic order in a child showing hypovolaemic signs despite visible oedema is a frequently tested safety judgement.

Watch for questions pairing steroid therapy with infection risk, asking the candidate to identify teaching points such as avoiding live vaccines during high-dose treatment or reporting fever immediately.
