09.05 Chronic Renal Failure for CCRN Review
Outline
Nursing Points
General
- Chronic renal failure
- Decline in kidney function
- Stages
- Diminished renal reserve
- 50% nephron loss
- Renal insufficiency
- 75% nephron loss
- End Stage Renal Disease (ESRD)
- 90% nephron loss
- Uremic Syndrome
- 100% nephron loss
- Inverse relationship
- As creatinine level increases GFR decreases
- Hyperkalemia
- Causes EKG changes
- Peak T waves
- High potassium level of 6.7-6.9
- Prolonged PR interval
- Potassium level 7
- Lose P wave
- Potassium level 7.5
- Wide complex
- Potassium level 7.8-7.9
- Biphasic
- Potassium level 8
- Sine wave
- Calcium chloride IVP – treatment for EKG involvement
- Protects heart to allow normal conductivity
- Does not lower K level
- Muscle weakness
- Treatment
- Insulin -hides potassium
- Glucose
- Sodium bicarb -pushes potassium into the cell
- K excelate –> removes potassium from cell into the bowel
- Calcium and Phosphate
- Reciprocal relationship
- Kidney disease
- Low vitamin D
- Low Calcium
- High Phosphate
- Treatment
- Amphogel –> Decreases phosphate
- Oscal –> Increase calcium
- Hyperphosphatemia
- Chvostek’s sign
- Trousseau’s sign
- Twitch
- Seizures
- Same as hypocalcemia
- Hypercalcemia
- Muscle weakness
- Apathy
- Diabetes
- Nephrogenic diabetes inspidus
- Same as hypophosphatemia
