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
Neurological system
CKS causes:
Altered mental ability Restless legs syndrome Muscle twitching, irritability Decreased concentration Peripheral neuropathy Seizures Dialysis encephalopathy
What does CKS cause to:
Integumentary
Musculoskeletal
Reproductive
Integumentary
-Pruritus
Musculoskeletal
- Systemic disorder of mineral and bone metabolism
- Results in skeletal complications
Reproductive
- Low sperm count, Infertility
- Decreased libido, sexual dysfunction
Psychological Manifestations
-
Personality and behavioural changes
Emotional ability
Withdrawal
Depression
Management Strategies
Dietary restrictions Fluid Restriction*** Cholesterol management Blood sugar management Weight management Anemia management*** (erythropoietin, iron, folic acid) Blood pressure management Daily Activity Smoking cessation Stress management
Treatment Options 4
Transplant
Conservative Care
Hemo Dialysis
Peritoneal Dialysis
Conservative Therapy
- Correct fluid volume overload or deficit
- Nutritional therapy
- Anemia therapy: erythropoietin, iron, folic acid
- Calcium supplements, phosphate binders
- Anti-hypertensives
What is Dialysis?
Procedure which:2
2 types:
Procedure which:
- Removes extra water from the body
- Removes waste products from the blood stream (removes waste)
2 types:
Peritoneal Dialysis – takes place inside the body
Hemodialysis – takes place outside the body (fake kidney) [2 needles into fistula/graft and connected to machine]
Artery - Vein fistula
Graft
What are they
and considerations
Connection between artery and vein
- No BPs
- No Ivs
- No blood tests
- No tight jewelry
a piece of living tissue that is transplanted surgically.
Kidney Transplantation
- Kidneys found where
- in hospital for how long
Healthy kidneys come from living donors or cadaveric donors
Usually hospitalized for 1-2 weeks
