Nursing Management—Acute
Glomerulonephritis
• Patient assessment
• Maintain fluid balance
• Fluid and dietary restrictions
• Patient education
• Follow-up care
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Chronic Glomerulonephritis
• Causes include repeated episodes of acute glomerular
nephritis, hypertensive nephrosclerosis, hyperlipidemia,
and other causes of glomerular damage
• Some patients are asymptomatic for years; as
glomerular damage increases, signs and symptoms of
renal insufficiency and renal failure develop
• Abnormal laboratory test results include urine with
fixed specific gravity, casts, and proteinuria; electrolyte
imbalances; and hypoalbuminemia
• Medical management is determined by symptoms

Nursing Management of
Chronic Glomerulonephritis

• Cardiac status
• Neurologic status
• Emotional support
• Teaching self-care
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Nephrotic Syndrome
• Any condition that seriously damages the
glomerular membrane and results in increased
permeability to plasma proteins
• Results in hypoalbuminemia and edema
• Causes include chronic glomerulonephritis, diabetes
mellitus with intercapillary glomerulosclerosis,
amyloidosis, lupus erythematosus, multiple
myeloma, and renal vein thrombosis
• Medical management includes drug and dietary
therapy

Renal Failure
• Results when the kidneys cannot remove wastes
or perform regulatory functions
• A systemic disorder that results from many
different causes
• Acute renal failure is a reversible syndrome that
results in decreased glomerular filtration rate (GFR)
and oliguria
• Chronic renal failure (ESRD) is progressive;
irreversible deterioration of renal function results
in azotemia
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Causes of Acute Renal Failure
• Hypovolemia
• Hypotension
• Reduced cardiac output and heart failure
• Obstruction of the kidney or lower urinary tract
• Obstruction of renal arteries or veins
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Causes of Chronic Renal Failure
• Diabetes mellitus
• Hypertension
• Chronic glomerulonephritis
• Pyelonephritis or other infections
• Obstruction of urinary tract
• Hereditary lesions
• Vascular disorders
• Medications or toxic agents

Question
The movement of solute (waste products) from an area of
higher concentration to an area of lower concentration is
which of the following?
a. Anuria
b. Diffusion
c. Osmosis
d. Ultrafiltration
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Nursing Management of the Hospitalized
Patient on Dialysis
• Protect vascular access; assess site for patency and
signs of potential infection, and do not use it for blood
pressure or blood draws
• Monitor fluid balance indicators and monitor IV therapy
carefully; keep accurate I&O and IV administration
pump records
• Assess for signs and symptoms of uremia and
electrolyte imbalance; regularly check lab data
• Monitor cardiac and respiratory status carefully
• Monitor blood pressure; antihypertensive agents must
be held on dialysis days to avoid hypotension
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Nursing Management of the Hospitalized
Patient on Dialysis (cont.)
• Monitor all medications and medication dosages
carefully; avoid medications containing potassium and
magnesium
• Address pain and discomfort
• Implement stringent infection control measures
• Monitor dietary sodium, potassium, protein, and fluid;
address individual nutritional needs
• Provide skin care: prevent pruritus; keep skin clean and
well moisturized; trim nails and avoid scratching
• Provide CAPD catheter care

contribute to altered nutritional intake, ie, stomatitis or
anorexia
