Glomerulonephritis
Key Points
- Ang glomerulonephritis ay pamamaga ng renal glomeruli na nagpapahina sa filtration ng fluid at metabolic waste.
- Ang acute cases ay madalas immune-triggered pagkatapos ng infection; ang chronic cases ay maaaring dulot ng autoimmune disease at tuloy-tuloy na inflammatory injury.
- Karaniwang findings ang hematuria, proteinuria, oliguria, edema, hypertension, at tumataas na BUN/creatinine kasabay ng bumababang GFR.
- Ang severe disease ay maaaring umusad tungo sa uremic complications, acute kidney failure, o chronic kidney damage.
- Ang nursing priorities ay infection management, fluid-balance surveillance, blood-pressure control, at structured self-management teaching.
Pathophysiology
Sinisira ng glomerular inflammation ang filtration membrane at binabawasan ang selective permeability control. Habang tumitindi ang inflammation, maaaring tumagas ang protein at dugo sa ihi habang bumababa ang kabuuang filtration capacity.
Ang acute glomerulonephritis ay karaniwang sumusunod sa immune activation pagkatapos ng infection (halimbawa streptococcal triggers). Ang chronic glomerulonephritis ay sumasalamin sa matagal na inflammatory injury, na madalas kaugnay ng autoimmune conditions gaya ng systemic-lupus-erythematosus at vasculitic disease patterns.
Classification
- Acute glomerulonephritis: Biglaang inflammatory onset matapos ang immune trigger na may mabilis na clinical change.
- Chronic glomerulonephritis: Progressive, long-duration inflammatory damage na may tuloy-tuloy na nephron loss.
- Immune-mediated forms: Autoantibody o immune-complex activity na nagtutulak ng persistent glomerular injury.
- Secondary inflammatory forms: Infection-, toxin-, o medication-associated inflammatory damage.
Nursing Assessment
NCLEX Focus
I-prioritize ang signs ng filtration failure kasama ng fluid-overload at blood-pressure deterioration trends.
- Tayahin ang urinary cues: hematuria, proteinuria, oliguria, at nagbabagong urine output pattern.
- Tayahin ang cardiovascular cues: hypertension, edema, jugular venous distention, at overload-related murmur changes.
- Tayahin ang neurologic at GI uremic cues: confusion, nausea, pagsusuka, poor appetite, at metallic taste.
- Tayahin ang integumentary at hematologic cues: pallor, pruritus, petechiae/easy bruising, at anemia-related fatigue.
- I-trend ang kidney at inflammatory diagnostics: BUN, creatinine, GFR, electrolytes, CBC, at urinalysis.
- I-review ang diagnostics para sa etiology at severity: renal ultrasound o CT, at kidney biopsy kapag inutos.
Nursing Interventions
- Suportahan ang paggamot sa underlying cause (infectious at immune-mediated pathways) at i-monitor ang response failure.
- Ibigay at i-monitor ang mga inutos na gamot (antibiotics, immunosuppressive agents, diuretics, at antihypertensives).
- I-monitor ang daily weights, intake/output, at 24-hour trends para matukoy agad ang fluid-overload progression.
- Ipatupad ang inutos na sodium/fluid restrictions at edema-reduction supports (halimbawa extremity elevation).
- I-coordinate ang renal-replacement escalation kapag nagkaroon ng acute failure, kabilang ang dialysis preparation at monitoring.
- Suportahan ang plasmapheresis pathways kapag excessive immune-complex burden ang target ng treatment plan.
- Turuan ang pasyente tungkol sa medication adherence, symptom escalation reporting (lumalalang edema, nabawasang urine output), at follow-up attendance.
- Palakasin ang nutrition planning, kabilang ang individualized protein guidance batay sa renal stage at kasalukuyang status.
Renal Deterioration Risk
Ang pagkaantala sa pagkontrol ng aktibong glomerular inflammation ay maaaring umusad tungo sa acute kidney failure, persistent uremia, at chronic renal damage.
Pharmacology
| Drug Class | Examples | Key Nursing Considerations |
|---|---|---|
| antibiotics(mga antibiotic) | class-based agents | Gamitin kapag may natukoy na bacterial trigger; i-monitor ang culture/lab response trends. |
| immunosuppressants(mga immunosuppressant) | corticosteroids, other agents | Binabawasan ang immune-mediated inflammation; i-monitor ang infection risk at therapy toxicity. |
| diuretics(mga diuretic) | class-based agents | Binabawasan ang edema/fluid burden; i-monitor ang urine output at electrolytes. |
| ace-inhibitors(ACE inhibitors) | class-based agents | Kinokontrol ang blood pressure at binabawasan ang proteinuria progression risk. |
| angiotensin-ii-receptor-blockers(angiotensin II receptor blockers) | class-based agents | Alternatibong blood-pressure/proteinuria pathway kapag clinically indicated. |
Clinical Judgment Application
Clinical Scenario
Isang client na may recent streptococcal illness ang may edema, hypertension, oliguria, hematuria, at tumataas na creatinine.
- Recognize Cues: Pattern ng filtration injury na may fluid overload at renal decline.
- Analyze Cues: Ang aktibong glomerular inflammation ay nagpapahina sa kidney function at nagpapataas ng complication risk.
- Prioritize Hypotheses: Pinakamataas na prayoridad ang pagpigil sa acute decompensation mula sa fluid overload at lumalalang renal failure.
- Generate Solutions: Paigtingin ang monitoring, ipatupad ang medication/fluid plans, at i-coordinate ang diagnostic clarification.
- Take Action: Ibigay ang inutos na therapy, i-trend nang mabuti ang labs at output, at agad i-escalate ang deterioration.
- Evaluate Outcomes: Bumababa ang edema at blood pressure, nagsi-stabilize ang urine output, at bumabagal ang paglala ng renal trend.
