Nephrotic vs Nephritic Syndrome: Protein Loss vs Inflammatory Damage
One syndrome leaks protein, the other leaks blood — but they're one letter apart, and NCLEX questions hinge on whether you pick "foamy urine with edema" or "cola-colored urine with hypertension." Swapping these loses the question every time.

Side-by-side2 compared
Dimension
Nephrotic Syndrome
Nephritic Syndrome
Mechanism & causes
- Glomerular membrane leaks protein
- Minimal change disease (children)
- Diabetes, lupus, amyloidosis
- Glomerular inflammation damages capillaries
- Post-streptococcal GN (children)
- IgA nephropathy, lupus, Goodpasture
Urine, edema & BP
- ★Foamy/frothy urine (massive protein)
- Generalized edema, anasarca; BP normal/low
- ★Cola-/tea-colored urine (RBCs)
- Periorbital edema; HTN; oliguria
Diagnostics & labs
- Massive proteinuria > 3.5 g/day
- Albumin <2.5; hyperlipidemia
- ★Hematuria with RBC casts
- Proteinuria <3.5; ↑BUN/Cr (azotemia)
Nursing priorities
- Daily weight, I&O, assess edema
- Infection prevention (lost immunoglobulins)
- Monitor BP, I&O, urine color
- Watch oliguria & azotemia; daily weights
Management
- Corticosteroids (esp. minimal change)
- Albumin, statin; ACEi/ARB to ↓ proteinuria
- Treat underlying cause/inflammation
- Antihypertensives, diuretics; antibiotics if strep
Patient teaching
- Low-sodium diet; report fever/infection
- Take steroids as prescribed; don't stop abruptly
- Sodium & fluid restriction; complete strep abx
- Report ↓/dark urine, swelling
Red flags — escalate
- Sudden dyspnea/leg pain → thromboembolism
- Signs of infection (peritonitis, sepsis)
- Severe HTN, headache → encephalopathy
- Rising BUN/Cr, anuria → acute renal failure
Complications
- ★Thromboembolism (lost antithrombin III)
- Infection, malnutrition, AKI
- Hypertensive crisis, fluid overload
- Progression to chronic GN / CKD

Clinical Pearl
Nephr-O-tic = prOtein Out (foamy urine, edema). Nephr-I-tic = Inflamed, blood In (cola urine, HTN).
