Q

Acute postinfectious glomerulonephritis (APIGN):

A
  1. May develop as a response to a gourp A beta-hemolytic streptococal infections of the skin or pharynx or as a result of infection by the Staphylococcus, Pneumococcus, or Coxsackie virus.

Q

Acute proliferative glomerulonephritis

A
  1. Glomerular damage results from immune complex reaction that localizes on the glomerular capillary wall.
  2. Antibody-Antigen complexes become lodged in the glomeruli -> inflammation and obstruction
  3. Glomerular membranes are thickened and capillaries in the glomeruli are obstructed by damaged tissue cells, leading to decreased GFR.
  4. Vascular permeability increases-> protein, RBCs, red cell clasts are excreted.
  5. Sodium & water are retained-> expanded intravascular volume & interstitial compartments and resulting in characteristic edema.

Manifestations

A
  1. abrupt onset of hematuria, proteinura,
  2. Salt & water retention-> increases extracellualr fluid volume-> HTN, Edema
  3. evidence of Azotemia (10-14 days after initial infection)
  4. Urine is brown or cola colored
  5. Edema primarialy in face, around eyes. Dependent- hands, & upper extremiteis.
  6. Fatigue, N/V/H.
16
Q

Older Adult manifestation:

A
  1. May have fewer symptoms
  2. Nausea, malaise, arthralgias, proteinuria- common
  3. HTN, Edema - seen less often
  4. Pulmonary infiltrates- may occur early due to worsening of preexisting condition such as heart failure.
17
Q

Acute phase

A
  1. Bed rest is a key component of treatment plan during acute phase.
  2. Edema & midle to moderate HTN should be treated with sodium restriction and diuretic- Lasix.
18
Q

Severe HTN w/Cerebral dysfunction

A
  1. Medical emergency

2. give diazoxide or hydralazine IV

19
Q

Fluid requirements determined by careful monitoring of:

A
  1. Urinary Output
  2. Weigth
  3. Bloodpressure
  4. Serum electrolytes
  5. Dietary restriction of sodium and potassium may be necessary with severe azotemia, protein intake may need to be limited.
20
Q

Diagnostic Tests:

A
  1. Throat or Skin Cultures- defect infection by group A beta hemolytic streptococci
  2. Antistreptolysin O tieter- streptococcal exoenzymes
  3. ESR- elevated in APIGN or lupus nephritis
  4. KUB (Kidney, Ureter, Bladder)- abdominal x-ray- evaulates kidney size. Enlarged= acute nephritis, Small=late Chronic
  5. Kidney Scan
  6. Biopsy- most reliable diagnostic for glomerular disorders, helps determine type, prognosis, and appropriate treatment
  7. BUN- measures urea nitrogen (end product of protein metabolism)
  8. Serum Creatinine- creatinine in the blood, excreted by kidnesy= indicator or kidney function. level>4= serious impairment
  9. Urine Creatinine- levels decrease when renal function is impaired
  10. Creatinine Clearance- used to evaluate GFR. amount of blood cleared of creatinine in 1 minute, depends on pressure of blood
  11. Serum electrolytes-
  12. UA- RBCs. proteins- 24 hour specimen.
21
Q

Avoid Nephrotoxic antibiotics

A
  1. Aminoglycoside antibiotics, streptomycin, some cephalosporins.
22
Q

Agressive Immunosupressive Therapy used for:

A
  1. To treat the acute inflammatory process such as RPGN, Goodpasture’s, and exacerbations of SLE
  2. When begun early, significantly reduces risk of end-stage renal disease and renal failure.
  3. Prednisone- large dose of 1mg/Kg/day
23
Q

Ace inhibitors

A
  1. Reduce protein loss associated with nephrotic syndrome
  2. Reduce proteinuria and slow the progression of renal failure.
  3. Protective effect on the kidney in clients with diabetic nephropathy.
24
Q

NSAIDs

A
  1. Also reduce Proteinuira in some clients

2. Can increase Salt and water retention

25
Q

Antihypertensives

A
  1. Maintain blood pressure, which is important because systemic and renal hypertension is associated with a poorer prognosis in clients with glomerular disorders.
26
Q

Bed Rest ordered during

A

Acute Phase!

27
Q

If edema is significant or client is hypertensive…

A
  1. Restrict sodium intake to 1-2g/day
28
Q

If Azotemia is present…

A
  1. Restrict proteins, thos included in the diet should be complete or high-value proteins. Compelte proteins supply amino acids required for growth and tissue maintenace.
29
Q

Treatment for RPGN and Goodpastures’s syndrome

A
  1. Plasmapharesis- remove damaging antibodies from plasma

2. Used in conjunciton with immunosupressive therapy.

  3. if Cath, use sterile intermittent or straight cath or maintain a closed drainage system for indwelling
  4. Instruct pt. on good hand hygiene, limit visitors & screen for upper respiratory infections.
36
Q

Risk for Impaired Skin Integrity:

A
  1. Dependent areas or areas prone to pressure are vulnerable to skin breakdown.
  2. Turn pt. frequently
  3. pad bony prominences or susceptibe areas with sheepskin or protect skin with a transparent dressing.
  4. Make sure bed is free of crumbs & wrinkles
37
Q

Risk for Imbalanced Nurtirition: Less than body requirements

A
  1. client follows a “no addes salt” and low-protein diet
  2. To increase appetitie, encourage family to bring clients favorite foods fomr home, serve age appropriate quantities to children, and allow children to eat with other clients or with family members.
38
Q

Fatigue:

A
  1. Anemia, loss of plasma porteins, headache, anorexia, and nausea compund the fatigue
  2. Schedule activites and procedures to provide adequate rest and energy conservation. Prevent unnecessary fatigue
  3. Assist with ADLs as need
  4. Reduce energey demands with frequent small meals and short periods of acitivity.
