Collaborative management:

 Preserve renal function

Renal Failure




Results when kidney’s cannot remove wastes or
perform regulatory functions
Systemic disorder resulting from many different
causes
Acute renal failure- reversible syndrome that
results in decreased GFR and oliguria
Chronic renal failure- progressive; irreversible
deterioration of renal function resulting in
azotemia
Acute Renal Failure


Pathophysiology
Types of acute renal failure include:
Prerenal
 Intrarenal
 Postrenal

Phases of Acute Renal Failure


Phases of rapid decrease in renal function lead
to the collection of metabolic wastes in the
body.
Phases include:
Onset
 Diuretic
 Oliguric
 Recovery


Acute syndrome may be reversible with prompt
intervention.

Treatment


Diet therapy
Dialysis therapies
Hemodialysis
 Peritoneal dialysis







Standard treatment
Dialysate solution
Vascular access
Continuous arteriovenous hemofiltration
Continuous venovenous hemofiltration
Posthospital Care



If renal failure is resolving, follow-up care may
be required.
There may be permanent renal damage and the
need for chronic dialysis or even transplantation.
Temporary dialysis is appropriate for some
clients.
Chronic Renal Failure




Progressive, irreversible kidney injury; kidney
function does not recover
Azotemia
Uremia
Uremic syndrome
Stages of Chronic Renal Failure



Diminished renal reserve
Renal insufficiency
End-stage renal disease

Imbalanced Nutrition: Less Than
Body Requirements

Interventions include:

Dietary evaluation for:
Protein
 Fluid
 Potassium
 Sodium
 Phosphorus


Vitamin supplementation
Excess Fluid Volume

Interventions:
Monitor client’s intake and output.
 Promote fluid balance.
 Assess for manifestations of volume excess:

Crackles in the bases of the lungs
 Edema
 Distended neck veins


Drug therapy includes diuretics.
Decreased Cardiac Output

Interventions:
Control hypertension with calcium channel blockers,
ACE inhibitors, alpha- and beta-adrenergic blockers,
and vasodilators.
 Instruct client and family to monitor blood pressure,
client’s weight, diet, and drug therapy.

Risk for Infection

Interventions include:
Meticulous skin care
 Preventive skin care
 Inspection of vascular access site for infection
 Monitoring of vital signs for manifestations of
infection

Risk for Injury

Interventions include:
Drug therapy
 Education to prevent fall or injury, pathologic
fractures, bleeding, and toxic effects of prescribed
drugs

Fatigue

Interventions:
Assess for vitamin deficiency, anemia, and buildup
of urea.
 Administer vitamin and mineral supplements.
 Administer erythropoietin therapy for bone marrow
production.
 Give iron supplements as needed.
