Exam 3: Urinary and Kidney 2 Flashcards
What is less common upper or lower UTIs
Upper UTIs
Upper UTI
Infection above the bladder
It occurs from upward spread of bacteria - like if a stricture or stone is not allowing bacteria in the bladder to empty and it then spreads into the ureters and kidneys
Could also be from systemic infections like those in the blood that reach the kidnes - and systemic infection can lead to abscesses (Ex: Tb can lead to abscess in the kidney)
What are upper UTIs usually due to
ascension of pathogenic bacteria from a bladder infection, static urine d/t obstruction, or systemic infections that result in abscesses
Upper UTIs include what
acute or chronic pyelonephritis (inflammation of renal pelvis)
Interstitial nephritis (inflammation of the kidney
Kidney abscesses
Pyelonephritis
Can be acute or chronic inflammation/infection of the renal pelvis
Acute Pyelonephritis s/s
chills
fever
leukocytosis
bacteriuria
pyuria
low back pain
flank pain
NV
HA
malaise
painful urination
Chronic Pyelonephritis s/s
Usually NO symptoms of infection unless an acute exacerbation occurs
Noticeable signs may include fatigue, HA, poor appetite, polyuria, excessive thirst and weght loss
When is chronic pyelonephritis diagnosed
often incidentally when being evaluated for HTN
What to look for on assessment for chronic pyelonephritis
poor urine concentrating ability
pyuria
azotemia
proteinuria
anemia
acidosis
Azotemia
nitrogenous waste in urine
When do we usually see s/s of pyelonephritis
usually only in acute exacerbations not so much chronic
How is the extent of chronic pyelonephritis checked
usually by IV urogram and lab work (lab work includes creatinine clearance, BUN,, and creatinine levels)
What is an important vital to check whenver a kidney issue is expected
Blood pressure - it is an important function of the kidneys
Common Nursing Dx for pyelnoephritis
1 PAIN
Infection
Alterations in voiding patterns
Knowledge deficits r/t lack of understanding of tests and procedures
Goals with Pyelonephritis
Pain reduction
Medication compliance
proper hygiene
Patient education on pyelonephritis is focused on ___.
prevention
Interventions for Pyelonephritis
Monitor VS, I&O, and Weight
Encourage fluids up to 3000 mL a day
Encourage adequate rest
Instruct on high calorie low protein diet
warm moist compresses to flank area
encourage warm baths (this one can cause infection though)
administer antibiotics analgesics antipyretics urinary antseptics and antiemetics as prescribed
monitor for signs of renal failure
education
How much fluid should be given a day to dilute urine in pyelonephritis
3-4 L / 3000mL-4000mL
What is an important sign of concerning I&O changes
increases or decreases in weight
Education topics for pyelonephritis
prevent further infection by adequate fluid consumption and regular bladder emptying, perineal hygiene and taking meds as prescribed
keep follow up appointments
Chronic Kidney Disease
Umbrella term to describe kidney damage or a decrease in the glomerular filtration rate for 3+ months
Untreated CKD can result in…
ESRD and a need for kidney transplant or dialysis
Risk Factors for CKD
Primary Cause: Diabetes
HTN
CV Disease
Obesity
What is different between Acute Kidney Injury and CKD
Acute Kidney injury is one time and reversible if you ID and treat promptly before it damages the function of the kidneys
CKD is 3+ months of this and the kidneys may progress to CRF
Causes of Acute Kidney Injury
hypovolemia
hypotension (decreased blood flow to kidneys)
Reduced cardiac output and heart failure
obstruction of kidney or lower urinary tract
obstruction of renal arteries or veins
may result in CKD but does not always
Causes fo CKD
diabetes
HTN!!!!!!!!
chronic glomerulonephritis
pyelo/other infections
obstruction of urinary tract if not treated
hereditary lesions
vascular disorders
medications/toxic agents
CKD may lead to need for…
Dialysis or Kidney Transplant if enough damage occurs
Stages of Chronic Renal Failure (CRF)
Stage 1: Slight Damage
- Mild Decrease in Fxn
- Moderate Decrease
- Severe Decrease
- ESRD
What is the GFR (Glomerular Filtration Rate) like at all 5 stages of CRF
- GFR >90
- GFR 60-89
- GFR 30-59
- GFR 15-29
- GFR <15
Things to Assess with CKD
fluid status
ID potential sources of imbalance
assess nutritional status
knowledge of their nutrition and I&Os
assess potential complications like HTN, anemia, weight change, etc
Nursing Dx for CKD
Excess fluid volume
Imbalanced nutrition
Deficient knowledge
Risk for situational low self esteem
Goals for CKD
maintain ideal body weight and dont have excess fluid
work with their preferences for an appropriate diet
adequate intake
Diet is very important to CKD but…
can be very restrictive - especially regarding preferences
Gerontologic Considerations for CKD
Risks like aging, HTN, atherosclerosis, HF, DM, and cancer predispose elders to kidney disease
Polypharmacy and changes in renal bloodflow, decreased GFR, and decreased renal clearance are also assoc with changes in renal function
What is the double sided issues with the gerontologic risk factors for renal disease
while they increase CKD incidence they also mask th s/s of it and make it harder to diagnose
Why do diuretics need to be monitored carefully when given to elderly
We need to assess for dehydration that can further compromise renal function and contribute further to renal failure
Conservative Gerontological management of CKD includes
nutritional therapy
fluid control
phosphate binders
Renal Replacement Therapy
Dialysis: Hemodialysis and Peritoneal Dialysis
Replacement therapy is needed when the kidneys cannot remove waste products - the waste that is usually excreted is urea
Goal of Hemodialysis
to remove toxic nitrogenous waste and water from the blood
clean and remove blood then return it to the system
What is vascular access for hemodialysis like
double lumen, large bore catheter into a large vein OR AV fistula or AV graft
AV Fistula/Graft
permanent joinings of artery and vein that takes 3 mo to heal - for more permanent access for hemodialysis
When there is a hemodialysis vascular access…
never take BP on that side and assess for bruits or thrills
Nursing Management Considerations for Hemodialysis
VS (esp. BP) and hemodynamic Status
Protecting Vascular access device
Palpating for thrills
Observe for infection
Dressing changes
Adjusting IV rate and strict I&O
Assess for complications
Administer blood transfusions during dialysis
Education
pain management
psychological support
Ways to protect vascular access
avoid BPs (place colorful band to indicate this), tight dressings, restraints, or jewelry over the device
How often should a thrill be checked for over the access for dialysis
every 8 hours - if absent there may be a blockage or clot
What complications and s/s should be monitored for when a patient is on hemodialysis
infection at site: redness, draining, fever, chills, swelling
Fluid overload
HF
pulmonary edema secondary to fluid build up
substernal chest pain, low grade fever, pericardial friction rub –> All 3 indicate pericarditis
Why is it so important to use proper dressing change technique when dealing with hemodialysis patients
because renal patients are more prone to infection
Why does the IV rate for hemodialysis need to be as slow as possible
because dialysis patients cannot secrete water - use a pump
If a patient on hemodialysis progresses to pericardial effusion what can be telling of this
the friction rub will disappear and heart sounds will be distant and pulsus paradoxus is noticeably worse
Why are blood transfusions administered during dialysis
so excess K+ can be removed
Things to education Hemodialysis patients on
dietary intake to prevent complications of hypoalbuminemia and hyperkalemia
infection prevention
proper med complianace
proper care of the catheter site
proper nutritional choices
When is peritoneal dialysis appropriate
for patients who cannot tolerate hemodialysis or have severe HTN, HF, and pulmonary edema that does not respond to hemodialysis
may be tx of choice for those unwilling or unable to go to hemodialysis
Goal fo Hemodialysis
remove toxxi substances and metabolic wastes
reestablish normal F&E balance
Peritoneal Dialysis Procedure
sterile dialysate is introduced into the peritoneal cavity through an abdominal catheter at intervals
waste products move from an area of higher concentration (blood) to an area of lower concentration (dialysate) through a semi permeable membrane (peritoneum)
