Q

How does chronic glomerulonephritis occur?

A

may be genetic

  • can be from the same causes of acute glomerulonephritis
  • develops more slowly with fewer symptoms and may result in irreversible damage
  • may result from unresolved acute glomerulonephritis

Q

Two types of antibody-induce immunological conditions affecting the glomerulus in glomerulonephritis, which are?

A

-Type 1 and Type 2
>both result in accumulation of antigens, antibodies, and complement in the glomeruli and GBM, which ultimately results in injury to the glomerular membrane and a decrease in effective filtration through the glomeruli
-there is an overall decrease in the glomerular filtration rate (GFR) and an increase in permeability to larger-size proteins

Q

Type 1 antibody induced immunological condition

A

the antibodies produced are specific for antigens within the glomeruli and glomerulus basement membrane (GBM)
-as a result of that interaction, immunoglobulins and complement are deposited along the basement membrane

Q

Type 2 antibody immunological condition

Q

Clinical Manifestations in glomerulonephritis

A

as a result of increased permeability, protein and blood are seen in the urine as well as WBCs and casts

  • patients present edematous, with decreased urine output and hypertension
  • BUN and creatinine are elevated

Q

Would albumin and complement levels be decreased or increased?

A

decreased albumin and complement levels

-decreased complement indicates an immune-mediated response

Q

Treatment

A

based on the cause of the disease and symptom management

-medications and supportive care

18
Q

Medications

A

focus on antibiotic treatment; Penicillin for post-streptococcal glomerulonephritis if the infection is actively present

  • diuretics and other anti-hypertensives to treat hypertension
  • corticosteroids not always recommended but may be used to modulate the inflammatory response triggered by an immunological mechanism
19
Q

Supportive care treatments

A
  • The edema is treated with the restriction of sodium and fluids
  • If BUN is elevated, reductions in dietary protein to reduce the buildup of metabolic waste
  • plasmapheresis
  • rest
20
Q

Supportive Care treatments: Plasmapheresis

A

reduce the immune-triggered inflammation
-is an extracorporeal separation of the blood components to filter out immune complexes created as a part of the immunological response; the filtered plasma is discarded while the red blood cells and a replacement colloid such as donor plasma are returned to the patient

21
Q

Assessment and Analysis: clinical manifestations is based on what?

A

are present because of the damage of the GBM

  • hematuria
  • oliguria
  • periorbital edema
  • peripheral edema of the lower extremities
  • generalized body edema
  • ascites
  • abdominal or flank pain
  • hypertension
22
Q

Nursing Diagnoses

A
  • impaired urinary elimination r/t effects of damage to the glomerular membrane
  • ineffective therapeutic regimen management r/t the lack of knowledge regarding the treatment regimen
23
Q

Nursing Assessments

A
  • vital signs
  • daily weights
  • intake and output
  • measuring abdominal girth or extremity size
  • skin condition
  • monitor dietary intake
  • lab analysis; RFTs, WBC count, urinalysis
24
Q

Assessments: Vital signs

A

hypertension is a common finding because of fluid retention associated with glomerulonephritis
-hypertension is a risk factor for cardiovascular disease, stroke, and renal failure

25
Q

Assessments: Daily weights

A

weight gain is associated with sodium and water retention

26
Q

Assessments: intake and output

A

is essential is assessing the accumulation of fluids

  • increases in fluid retention can develop because of the potential sodium retention associated with renal impairment
  • fluid retention is a risk factor for elevated blood pressure and heart failure
27
Q

Assessments: measuring abdominal girth or extremity size

A

important in assessing fluid retention

-fluids tend to pool in dependent areas such as the abdomen or extremities

28
Q

Assessments: Skin condition

A

edema can increase the risk of skin breakdown

29
Q

Assessments: monitor dietary intake

A

a patient with glomerulonephritis has the potential for malnourishment from the excessive loss of protein in the urine because of the damage of the glomeruli

  • excess sodium intake can cause fluid retention, resulting in elevated blood pressure and heart failure
  • protein intake may need to be limited if the BUN is elevated and there are no signs of malnutrition
30
Q

Assessment: Renal Function Tests (RFT)

A

BUN/creatinine should be monitored to track renal function

31
Q

Assessment: WBC count

A

elevations indicate infection

32
Q

Assessment: Urinalysis

A

protein and RBCs can be found in the urine because of damage in the GBM

33
Q

Nursing Actions

A
  • administer anti-hypertensives as prescribed
  • administer corticosteroids as ordered
  • maintain low to moderate protein diet
  • dietary sodium and fluid restriction
34
Q

Actions: administer anti-hypertensives as prescribed

A

diuretics are used to combat sodium and fluid retention

-other anti-hypertensives such as ACE inhibitors may be prescribed to control blood pressure adequately

35
Q

Actions: administer corticosteroids as ordered

A

may be indicated to modulate the inflammatory response triggered by the immunological mechanism

36
Q

Actions: maintain a low to moderate protein diet

A

care must be taken to limit protein intake if the BUN is elevated, but a low to moderate protein diet may be needed to treat protein loss through the urine

37
Q

Actions: dietary sodium and fluid restriction

A

necessary to prevent fluid retention, which can cause elevated blood pressure and heart failure

38
Q

Nursing Teachings

A
  • overview of the disease process
  • prescribed medications
  • dietary restrictions
  • avoid infections
39
Q

Evaluating Care outcomes

A

based on improvements in kidney function and the symptoms associated with glomerulonephritis

  • monitoring serum BUN, creatinine, and electrolytes is important in assessing the condition of the patient
  • patient teaching can be evaluated by the patients verbalization of information regarding the condition
40
Q

A well-managed patient

A

has a blood pressure within normal limits, no edema, and renal function within normal limits
