Glomerulonephritis Test 5 Flashcards
1
Q
Glomerulonephritis
A
Immunologic process involving the urinary tract predominantly affect the renal glomerulus
-glomerular injury as result of inflammation, affecting both kidneys equally
2
Q
Etiology of glomerulonephritis:
A
- immunological reaction
- SLE
- strep infection
- Vascular injury
- hypertension
- Metabolic disease
- diabetes mellitus
- Disseminated intravascular coagulation
3
Q
Glomerulonephritis patho:
A
- Antigen-antibody complex formation and reaction with glomerular tissue
- causes inflammation in glomerulous -primary vs. ssecondary-associated with systemic disease-acute, chronic, idiopathic or may occur as a complication of other diseases-rapidly progressive (loss of fx in days/weeks)
4
Q
Attacks the glomerular basement membrane which-
A
becomes more porous
- proteinuria, hematuria, azotemia
- decreased glomerular filtration
- retention of metabolic waste
- retention of water and sodium
5
Q
Early S/S of glomerulonephritis:
A
- proteinuria and hematuria: early sign
- bacteria neg in the U/A
- Azotemia: elevated BUN and Creatinine early sign
- Increased urine specific gravity
- Elevated antistreptolysin O titer/
- Elevated Sed rate
- Metabolic acidosis d/t impaired glomerular filtration causing retention of waste products
- Oliguria
6
Q
S/S of glomerulonephritis early/late:
A
- Anemia
- Fatigue
- Anuria
- HA
- Malaise
- mild fever
- anorexia
- flank pain or CVA tenderness
7
Q
S/S of glomerulonephritis (late):
A
- Increased B/P r/t fluid overload
- Edema
- JVD
- Periorbital edema
- End stage renal failure
- irreversible renal failure occurs in less than 1% of patients
- Circulatory congestion
- dyspnea
- CHF
- Complications r/t fluid overload
- CHF
- encephalopothy
- pulmonary edema
- sepsis from infection
- end stage renal failure
- *Irreversible renal failure occurs in less than 1% of patients
8
Q
Glomerulonephritis Diagnostic studies:
A
- Urinalysis
- bacteria neg
- RBC, WBC, and casts
- urine smoky or rusty in appearance
- hematuria
- proteinuria
- Possible decreased urine creatinine clearance
- Serum BUN/Creatinine
- ESR
- Antistreptolysin-O titer (ASO)
- Chronic
- fixed specific gravity
- metabolic acidosis
9
Q
Glomerulonephritis prevention:
A
- early detection and treatment of respiratory infections to prevent increase antigen/antibody complex formation
- supportive, symptomatic care
- diuretics for severe fluid overload
- antihypertensive therapy (only after fluid control has proven unsuccessful)
- Rest during acute stage to decrease workload on kidneys
- decrease the metabolic activity
- advance activity as symptoms disappear; no protein or blood in the urine
10
Q
Dietary management:
A
- Dietary sodium restriction
- fld volume deficit r/t decrease glomerular filtration rate
- Potassium restriction
- if GFR is <10 ml/min
- hyperkalemia can cause dysrhythmia and neuromuscular symtoms
- protein restriction
- 1-1.2 g/day when BUN/Creatinine is elevated
- to decrease metabolic waste products and decrease stress on the kidney
- Sufficient dietary carbohydrates
- carb prevention protein being used as energy, leading to muscle wasting and nitrogen imbalances
- 2500-3500 calories/day
- monitor pt for weight loss
11
Q
Chronic Glomerulonephritis:
A
- reflects the end stage of glomerular inflammatory disease from progressive destruction of the glomeruli
- Leads to gradual loss of renal function from tubular atrophy, chronic interstitial inflammation and arteriosclerosis
- Extremely variable
- Insidious or rapid
- May follow AGN but often there is no hx of infection
- Treatment mirrors AGN and is supportive and symptomatic
- No specific therapy to arrest or reverse the disease process
- Treatment of renal failure begins when illness progress to end stage
12
Q
S/S
A
- U/A- foamy dark smokey color, protein and blood will decrease as the fewer nephrons are intact. Urine specific gravity will become fix same as the plasma. Casts in the urine
- Metabolic Acidosis- r/t impaired glomerular filtration.
- HA especially in morning
- HTN- d/t activation of renin-angiotensin aldosterone system.
- dyspnea on exertion
- blurred vision
13
Q
S/S continued
A
- Lassitude
- weakness
- fatigue
- edema
- nocturia
- effects on the GI:
- anorexia
- weight loss
