25
Diuretic phase of AKI
``` Movement towards recovery Starts 2-6 weeks Lasts 1-3 weeks Renal perfusion and GFR increase LARGE DILUTE URINE Risk for dehydration and electrolytes 10L/hr ```
26
Recovery phase of AKI | Convalescent phase
Takes up to a year | Damage does not grow back
27
Signs and symptoms of AKI
``` Weight gain Decreased urine output Fluid volume overload Nausea HA, confusion Cramps, twitching Dysthymia ```
28
Drug History that may lead to AKI
NSAIDS Antibiotic Some antifungals
29
Treatment for AKI
``` IV fluid challenge Calcium channel blockers Bicarbonate infusion Renal diet Dialysis ```
30
More drugs that hurt the kidney
Acetylcytetine Dopamine Diuretics
31
Renal diet
Stay away from Potassium Sodium Phosphorus
32
Prevention and health maintenance
Avoid hypotension Monitor labs Monitor weight Use touch nephrotoxic drugs
33
Nursing care in AKI
Monitor fluid balance Labs Maintain MAP of 65 Educate
34
Causes of CKD
Diabetes HTN AKI Genetic
35
CKD
Progressive, irreversible kidney injury GFR 15 or less Azotemia Uremia
36
Renal filtering function decreases fluid and electrolytes
Acidosis Hyperkalemia Hypertension
37
Wastes build up in blood Toxic to CNS, RBCs, platelets
Increased creatinine and BUN
38
Kidney metabolic functions decrease
Erythropoietin | Vitamin D activation
39
No symptoms of CRF until
75-80% loss of nephrons
40
Chronic renal failure GFR
Less than 60ml/min for 3 months or more
41
CRF difficult to diagnose
Healthy nephrons enlarge to compensate
42
Stage 1
At risk | Greater than 90
43
Stage 2
Mild 60-89
44
Stage 3
Moderate 30-59
45
Stage 4
Severe 15-29
46
Stage 5
End stage | Less than 15
47
Stage 2..... | What to do?
Control risk factors No NSAIDS No ACE/ARBS
48
What happens to patient at stage 2
``` 75-90% loss Polyuria Nocturia Hyponatremia Increase in BUN May be diet controlled ```
49
Stage 3, what to do?
Same as #2
50
Stage 4 what to do?
Initiate AV fistula
51
RRT is considered for
Fluid overload Really bad hyperkalemia Symptoms from azotemia
52
Stage 5, what to do ?
More than 90% loss Hyperkalemia kills them Death without transplant or RRT
53
CKD manifestations
Kidney changes Metabolic changes Electrolyte changes
54
Calcium can not be
Absorbed from food due to decrease production of vitamin D, also stimulated by kidneys
55
Calcium is reabsorbed from the bones to
Balance the loss in the blood and pH of blood Also need for muscle contraction
56
Phosphate binders
Eat with food to decrease phosphorus | Keeps calcium up and bones in better shape
57
Calcium and blood
Calcium is needed for clotting cascade
58
Uremia manifestations
``` Metallic taste in mouth Anorexia Nausea Vomiting Muscle cramps Uremic frost Itching Fatigue Hiccups Edema Dyspnea Paresthesias ```
59
Creatinine
Comes from proteins in skeletal muscle
60
BUN levels
Vary with protein intake
61
Renal osteodystrophy
Less vitamin D from kidney= less calcium Increased phosphorus Increased parathyroid hormone Bone mineral loss
62
Pericarditis
Occurs with CKD | Pericardial sac becomes inflamed from toxins
63
Decreased erythropoietin levels
Decreased RBC lifespan | Decreased platelets
64
Calcium channel blockers best for
Improve GFR
65
ACE inhibitors best for
Slow progression of pts with CKD and hypertension
