Q

Changes in creatinine levels indicates a

A

chronic problem with the kidneys. It is a waste product that is filtered out by the kidneys, so it takes some time to build up once the kidneys start fucking up.

What is AKI?
Acute kidney injury, When the function of the kidneys goes down drastically after an injury to the organ
26
Changes in creatinine with AKI?
50% increase above baseline creatinine
27
How does hypovolemia, hypotension, reduced cardiac output and heart failure affect the kidneys?
Blood flow is needed for the kidneys to work properly. Hypovolemia and hypotension could cause less fluid to get to the kidneys, which fucks them up
28
Causes of AKI
hypovolemia, hypotension, reduced cardiac output, heart failure, obstruction of the kidneys, lower urinary tract, renal arties or renal veins could all cause AKI
29
categories of AKI
prerenal - when damage occurs before the kidneys (such as poor perfusion to the nephrons) intrarenal - when damage occurs to the kidneys postrenal - obstruction distal to the kidneys
30
phases of AKI
Initiation - the injury Oliguria - decreased urine output (less than 30 mLs) increased BUN and potassium Diuresis - gradual increase of urine output. Monitor for dehydration, especially in older patients. recovery - improvement in renal function. Can take up to several months. This is not a super fast process.
31
chronic kidney disease causes
Diabetes mellitus, hypertension, chronic glomerulonephritis, pyelonephritis or other infections, obstruction of urinary tract, hereditary lesions, vascular disorders, medications or toxic agents
32
Nephrosclerosis
Hardening or renal arteries (expected with aging). Major cause of chronic kidney disease *treat underlying hypertension* Increased risk in African Americans and diabetic nephropathy
33
Acute nephritic syndrome
34
Glomerulonephritis
35
Acute Nephritic Syndrome
Postinfectious glomerulonephritis, rapidly progressive glomerulonephritis, and membranous glomerulonephritis whatever that means most common cause is strep throat Usual treatment is antibiotics, corticosteroids and sometimes immunosuppresants
36
Acute Nephritic Syndrome Manifestations
hematuria, edema, azotemia, proteinuria, and hypertension
37
Azotemia
abnormal increase of nitrogenous waste in the blood. Leads to increased BUN. Urine will look like cola
38
Nursing management of acute nephrotic syndrome
assessment, education, follow up Maintain fluid balance, fluid and dietary restrictions (low salt, low protein, high carbohydrates. Possible fluid restrictions)
39
Chronic Glomerulonephritis
Repeated acute glomerular nephritis, hypertensive nephrosclerosis, hyperlipidemia, and other causes of glomerular damage
40
Glomerulonephritis symptoms and lab changes
can be asymptomatic for years urine with fixed specific gravity, casts, proteinuria, electrolyte imbalances, and hypoalbuminemia
41
Nursing management for chronic glomerulonephritis
Potential fluid and electrolyte imbalances, cardiac status, neurologic status (can have neuropathy and possibly diminished deep tendon reflexes)
42
Nephrotic Syndrome
Any condition that seriously damages the glomerular membrane and results in increased permeability to plasma proteins. Leads to hypoalbuminemia and edema
43
Causes of Nephrotic Syndrome
chronic glomerulonephritis, diabetes mellitus with intercapillary glomerulosclerosis, amyloidosis, lupus erythematosus, multiple myeloma, and renal vein thrombosis
44
Polycystic Kidney Disease
Genetic disorder—most common inherited cause of kidney failure. cysts may also be in other organs Autosomal dominant and autosomal recessive
45
Polycystic kidney disease treatment
No cure, supportive treatment. Patients will need dialysis or kidney transplants
46
risk factors for renal cancer
Tobacco use, increased BMI, African American descent
47
symptoms of renal cancer
May be asymptomatic with only painless hematuria with dull back pain
48
Chronic renal disease (ESRD)
a progressive, irreversible deterioration of renal function that results in azotemia (build up of BUN and creatinine)
49
assessment for chronic renal disease
Fluid and nutritional status, patient knowledge, activity tolerance, self-esteem, potential complications
50
complimentary problems to kidney disease and injury
Pericarditis, pericardial effusion, pericardial tamponade Hypertension, anemia, bone disease and metastatic calcifications Hyperkalemia, improper calcium balance, can lead to changes in vitamin D
51
assessment for patient on hemodialysis
protect vascular access for dialysis (keep it clean, no BP no blood draw) closely watch and maintain fluid balance, monitor cardiac and respiratory systems closely (hold cardiac medications before dialysis) watch for s/s of uremia and electrolyte imbalance, regularly check lab data
52
interventions for patient on hemodialysis
monitor medications and dosages, address pain, infection control measures, moisturize their skin bc they're gonna get very dry
53
diet for dialysis patients
low sodium, potassium, protein restrictions, fluid restrictions, individual nutritional needs
54
Anuria
is less then 50 mL in 24 hours
55
Oliguria
urine output less than 400 mL in 24 hours
56
Lower UTI
cystitis, prostatitis, urethritis
57
Upper UTI
pyelonephritis, interstitial nephritis, renal abscess, perirenal nephritis
58
nursing intervention for UTI
Medications as prescribed: antibiotics, analgesics, and antispasmodics. Application of heat to the perineum to relieve pain and spasm Increased fluid intake Avoidance of urinary tract irritants such as coffee, tea, citrus, spices, cola, and alcohol Frequent voiding Patient education
59
causes of urinary retention
Adults 60 years and older may have 50 to 100 mL of residual urine remaining in the bladder after voiding Postoperative spasms Diabetes, prostatic enlargement, urethral pathology, trauma, pregnancy, neurologic disorder medications (anesthesia among others)
60
Lithiasis
stones. Usually calcium of some sort or uric acid
61
Genitourinary tract injury management
control hemorrhage, pain and infection; monitor for oliguria, shock, s/s acute peritonitis
62
ilieal conduit surgery patient education
pus and mucous in the urine may be seen in the urine depending on the type of tissue used to create the stoma
63
what does 24 hour urine measure
creatinine, urea nitrogen, sodium, chloride, calcium, catecholamines, and proteins
64
creatinine
results form protein and muscle breakdown. kidney function must be 50% lost for a difference to be apparent
65
BUN
blood urea nitrogen breakdown of protein in the liver, creating the biproduct BUN which is excreted by the kidneys
66
hemodialysis vs peritoneal dialysis
hemodialysis is blood running through a dialyzer and back into circulation. peritoneal dialysis is when hypertonic dialysate solution is inserted in the peritoneal cavity and then drained at the time it needs to be
67
old person respiratory changes
Alveoli can lose their shape and become baggy. The diaphragm can, over time, become weaker, decreasing the ability to inhale and exhale
