January 28 - Chronic Kidney Disease Flashcards
Kidney disease is a result of:
Creating:
Acute or Chronic
Kidney disease may result in the partial or complete impairment of kidney function, resulting in an inability to excrete metabolic waste products and water.
Acute or Chronic
Acute Kidney Injury (previously termed acute renal failure)
What is the Etiology
May progress to
Previously termed acute renal failure (ARF)
Etiology: prerenal, intrarenal, postrenal
May progress to chronic kidney disease (CKD)
What is Chronic Kidney Disease Presence: Progressive: How many stages: End result is?
Presence of kidney damage or decreased level of kidney function (Glomerular filtration rate GFR<60ml/minutes) for 3 months or more
Progressive, irreversible loss of kidney function
Divided into 5 stages depending on level of decrease in function
End result is systemic disease affecting every organ
5 Stage of Kidney Disease
1 = kidney dmg with normal GFR = > 90 2 = Kidney Dmg with mild GFR = 60-89 3 = Moderate GFR = 30-59 4 = Severe GFR = 15-29 5 = Kidney Failure < 15 (or dialysis)
Kidney Disease Etiology
Diabetes Uncontrolled Hypertension Chronic kidney infections/inflammation Severe Injury Inherited disorders Congenital Defects Certain Medications
Clinical Manifestations
Retained substances:
Urea Creatinine Phenols Hormones Electrolytes Water Other substances
Nursing Assessment
Urinary changes Edema Significant change in weight Shortness of breath (SOB) Skin Changes GI concerns – N & V, acute pain Fatigue Change in cognitive function
Diagnostic Studies
Urine dipstick : Persistent proteinuria
Albumin-creatinine ratio
What is Uremia
And SS
Syndrome that incorporates all the signs and symptoms resulting from build up of waste products and excess fluid associated with kidney disease.
Early s/s: n & v, fatigue, pruritus, hypertension, proteinuria, hyperglycemia
What is Polyuria
Oliguria
Anuria
Polyuria
Results from inability of kidneys to concentrate urine
Specific gravity fixed around 1.010
Oliguria
Occurs as CKD worsens
Anuria
Urine output <40 mL per 24 hours
Electrolyte/Acid-Base Imbalances
Potassium:
Sodium:
What alterations
State of:? which does
Potassium: hyperkalemia
Sodium: edema, hypertension, heart failure
Calcium and phosphate alterations
Magnesium alterations
Metabolic acidosis
Inability to excrete acid; defective reabsorption/regeneration of bicarbonate
Metabolic disturbances
Accumulation
Altered Carbohydrate metabolism
Elevated Triglycerides
Waste product accumulation
-As GFR ↓, BUN ↑ and serum creatinine levels ↑
Altered carbohydrate metabolism
-Cellular insensitivity to the normal action of insulin
Elevated triglycerides
-Altered lipid metabolism
Hematological System
Anemia
Bleeding tendencies
Infection
Anemia
-↓ production of erythropoietin
Bleeding tendencies
-Defect in platelet function
Infection
- Changes in leukocyte function
- Altered immune response and function
- Diminished inflammatory response
Cardiovascular system
Most common form of kidney death is cardiac
CKS causes:
Hypertension Heart failure Left ventricular hypertrophy Peripheral edema Dysrhythmias Pericarditis
Gastrointestinal System
CKS causes:
Mucosal ulcerations Stomatitis Uremic fetor GI bleeding Anorexia Nausea & Vomiting
