AnswerAnswer
True
The most accurate indicator of fluid loss or gain in an acutely ill patient is weight. An accurate daily weight must be obtained and recorded. A 1 kg weight gain is equal to 1000 mL of retained fluid.

Chronic GlomerulonephritisChronic Glomerulonephritis
• Causes include repeated episodes of acute glomerular nephritis, hypertensive nephrosclerosis, hyperlipidemia, and other causes of glomerular damage.
• Symptoms vary; may be asymptomatic for years, as glomerular damage increases, before signs and symptoms develop of renal insufficiency/failure.
• Abnormal laboratory tests include urine with fixed specific gravity, casts, and proteinuria; and electrolyte imbalances and hypoalbuminemia.
• Medical management is determined by symptoms.

Renal FailureRenal 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 GFR and oliguria
• Chronic renal failure (ESRD) is a progressive, irreversible deterioration of renal function that results in azotemia

• Protection of vascular access; assess site for patency and signs of potential infection, and do not use for blood pressure or blood draws.
• Monitor fluid balance indicators and monitor IV therapy carefully; accurate I&O, IV administration pump.
• Assess for signs and symptoms of uremia and electrolyte imbalance; regularly check lab data.
• Monitor cardiac and respiratory status carefully.
• Hypertension: monitor blood pressure, antihypertensive agents must be held on dialysis days to avoid hypotension.

InterventionsInterventions
• Pain relief measures and analgesic medications
• Promote airway clearance and effective breathing pattern by appropriate pain relief, deep breathing coughing exercises, and incentive spirometry and positioning
• Monitor UO and maintain potency of urinary drainage systems
• Use strict asepsis with catheter and appropriate technique in providing all care
• Monitor for signs and symptoms of bleeding
• Encourage leg exercises, early ambulation, and monitor for signs of DVT
