Exam #7 Flashcards
Common GU Symptoms
Pain
Changes in voiding
Gastrointestinal symptoms
Unexplained anemia
Glomerular Filtration Rate
Amount of plasma filtered through the glomeruli per unit of time
125-200 mL/hour
BUN
10-20 mg/dL
Creatinine
Waste product of skeletal muscles
0.7–1.4 mg/dL
Anuria
Urine less than 50 mL in 24 hours
Oliguria
Urine less than 0.5 mL/kg/hour
GU Diagnostic Exams
UA/Urine culture Specific gravity Osmolality BUN/Creatinine KUB Ultrasonography CT/MRI Nuclear scans Intravenous urography Renal angiography Cystoscopy Biopsies
Cystoscopy Nursing Care
NPO Status
Post procedure: tell them to expect burning with urination, hematuria, polyuria, high risk for UTI, monitor for urinary retention
Treat with sitz bath, antispasmodics, intermittent catheter
Kidney Biopsy
Percutaneous or open biopsy
Check coags before procedure
Pre-op urine specimen
NPO/IV
Post-op: IV to keep urine clear, pain control
Gerontological Considerations
GFR decreases
More susceptible to ARF and CRF due to sclerosis of glomeruli and renal vasculature
Renal reserve is decreased
Higher risk for adverse drug effects/interactions
Prone to hypernatremia and fluid volume deficit
Decreased bladder wall contractility
Chronic Kidney Disease
Damage to kidneys without signs/symptoms, related to acute inflammation
5 is end-stage renal failure
Screening and early intervention is important; prevent progression by decreasing risk, help eliminate HTN, treat anemia, decrease hyperglycemia
S/S of CKD
Elevated creatinine
Anemia
Metabolic acidosis, abnormal calcium and phosphorus levels
Fluid retention, edema, S/S of CHF, increase in potassium
Electrolyte imbalances
Difficult to control HTN
Treatment of CKD
Find the cause and eliminate it
Keep BP below 130/80
Prevent complications by controlling hyperglycemia, managing anemias, decreasing salt intake
Diet: low protein, low sodium, low potassium, low phosphate
Primary Glomerular Diseases
Acute nephritic syndrome
Chronic glomerulonephritis
Major Clinical Manifestations of Primary Glomerular Diseases
Proteinuria, hematuria
Decreased GFR
Decreased excretion of sodium, edema
Hypertension
Acute Nephritic Syndrome
Acute glomerulonephritis
Caused by immune respone
Signs/Symptoms of Acute Nephritic Syndrome
Hematuria, edema
Azotemia, proteinuria
Oliguria, hypoalbuminemia, hyperlipidemia, urinary casts, BUN and CRE increased, urine output decreases, Hgb and Hct decreased, hypertension
Treatment of Acute Nephritic Syndrome
Biopsy of kidney
Prognosis is excellent
Some need dialysis if it becomes a chronic problem
Treat the symptoms, steroids to help with inflammatory process, low sodium diet, keep track of intake and output, antibiotics
Complications of Acute Nephritic Syndrome
Hypertensive encephalopathy
Heart failure
Pulmonary edema
Chronic Glomerulonephritis
Kidneys decrease in size and increase in fibrous content
Glomeruli and tubules are scarred
Renal arteries are thickened
Leads to stage 5 CKD
Cause of Chronic Glomerulonephritis
Repeated episodes of acute nephritic syndrome, hypertensive nephrosclerosis, glomerular sclerosis
Secondary: lupus
Signs/Symptoms of Chronic Glomerulonephritis
May not have any at first
Increased irritability, increased nocturia, headache, dizziness, digestive problems, look chronically ill/poorly nourished, yellow-gray pigmentation, retinal hemorrhage, heart failure
Treatment of Chronic Glomerulonephritis
Treat symptoms
Sodium/water restriction
Antihypertensives
Daily weight and diuretic medications
Careful protein with a high biologic value
Dialysis
Nephrotic Syndrome
Type of renal failure with increased glomerular permeability
Caused by damage to glomerular capillary membrane
