Exam 3: Urinary and Kidney 2 Flashcards
1
Q
What is less common upper or lower UTIs
A
Upper UTIs
2
Q
Upper UTI
A
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)
3

24
Q
What is different between Acute Kidney Injury and CKD
A
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
25
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
26

HTN!!!!!!!!
chronic glomerulonephritis
pyelo/other infections
obstruction of urinary tract if not treated
hereditary lesions
vascular disorders
medications/toxic agents

ID potential sources of imbalance
assess nutritional status
knowledge of their nutrition and I&Os
assess potential complications like HTN, anemia, weight change, etc
31
Nursing Dx for CKD
Excess fluid volume
Imbalanced nutrition
Deficient knowledge
Risk for situational low self esteem
32
Goals for CKD
maintain ideal body weight and dont have excess fluid
work with their preferences for an appropriate diet
adequate intake
33
Diet is very important to CKD but...
can be very restrictive - especially regarding preferences
34
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
35
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
36
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
37
Conservative Gerontological management of CKD includes
nutritional therapy
fluid control
phosphate binders
38
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
39
Goal of Hemodialysis
to remove toxic nitrogenous waste and water from the blood
clean and remove blood then return it to the system
40
What is vascular access for hemodialysis like
double lumen, large bore catheter into a large vein OR AV fistula or AV graft
41
AV Fistula/Graft
permanent joinings of artery and vein that takes 3 mo to heal - for more permanent access for hemodialysis
42
When there is a hemodialysis vascular access...
never take BP on that side and assess for bruits or thrills
43
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
44
Ways to protect vascular access
avoid BPs (place colorful band to indicate this), tight dressings, restraints, or jewelry over the device
45
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
46
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
47
Why is it so important to use proper dressing change technique when dealing with hemodialysis patients
because renal patients are more prone to infection
48
Why does the IV rate for hemodialysis need to be as slow as possible
because dialysis patients cannot secrete water - use a pump
49
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
50
Why are blood transfusions administered during dialysis
so excess K+ can be removed
51
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
52
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
53
Goal fo Hemodialysis
remove toxxi substances and metabolic wastes
reestablish normal F&E balance
54
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)
55
How much longer is peritoneal dialysis
pretty continuous - does what hemodialysis does in 6-8 hours over 36-48 hours
56
Types of Peritoneal Dialysis
Acute Intermittent Peritoneal Dialysis
Continuous Ambulatory Peritoneal Dialysis
Continuous Cyclic Peritoneal Dialysis
57
Acute Intermittent Peritoneal Dialysis
A nurse warms, spikes, and hangs each container of dialysate
Requires strict asepsis
If dialysate does not drain right, nurse will facilitate draining by turning patient from side to side or raising the head of the bed - NEVER push the catheter further into the peritoneal cavity
58
Common routine for acute intermittent peritoneal dialysis
hourly exchanges that involve 10 minute infusion, 30 minute dwell time and 20 minute drain time
59
Impotant assessments to be done with acute intermittent peritoneal dialysis
I&O
VS
Weight
Patient status
Skin turgor and mucous membranes to evaluate fluid status
presence of edema check
60
Continuous Ambulatory Dialysis (CAP)
2nd most common form
performed at home 4-5 times a day every day
Longer dwell time --> better results
managed by the patient or a trained caregiver
61
Continuous Cyclic Peritoneal Dialysis
uses a cycler machine and combines overnight intermitted PD with a prolonged dwell time during the day
lower infection rates since fewer bag changes and tubing disconnections occur
greater freedom to work
May need home visits by nurse or f/u calls or visits to outpatient settings to make sure dialysate is ok and BP is monitored carefully
62
Renal Calculi Cause what pain
RENAL COLIC - originating in lumbar region radiating around the side and down toward the testicle in mean and to the bladder in women

high protein and sodium diets
81
Cystoscopy
Surgical management for stones in the bladder or lower ureter
1-2 catheters are inserted past the stone and mechanically guide it down
NO INCISIONS
82
What occurs after the cystoscopy removes the stone
the catheters stay in place for 24 hours to drain urine trapped proximal to the stone and dilate the ureter
and continuous chem irrigation is used to dissolve the stone
83

inform client that ambulation is important (get them up and walking)
94
ESWL Management
Assess and manage foley cath if needed
Assess nephrostomy tube (may be placed 1-5 days for chemical irrigation)
Encourage 3-4 L of fluid a day following procedure
instruct client to monitor for complications of infection, hemorrhage, and fluid extravasation into retroperitoneal cavity
95
Ureterolithotomy

may need a nephrostomy tube and indwelling catheter after
tube will need aspetic tecnique or pyelnephritis can occur
99
Pyelolithotomy
Large flank incision into kidney to remove stones from the renal pelvis
penrose drain and indwelling catheter
100
When is a partial or total nephrectomy done
for extensive kidney damage, renal infection, or severe obstruction and to prevent stone recurrence
101
What is postoperative care of a partial or total nephrectomy like
Plan of care is based on incision location and type of drainage tubes (penrose drains lg amounts of urine - the tube is connected to a bag to collect urine)
Protect skin from urinary damage (ostomy pouch over penrose drain to protect it if excessive urinary drainage)
Monitor nephrostomy tube (attached to drainage bag for free flow of urine) and folet with strict I&O
102
If there is urethral cathters in place after a nephrectomy...
NEVER IRRIGATE THEM - they are for draining urine
We can irrigate the nephrostomy tube if there is an order, but we never irriagate these
103
What are important nursing interventions for any open procedure
maintaining airway clearance and breahting
relieving pain - heat, analgesia
promoting urinary elimination - neph tube
104
Important interventions/care post nephrostomy
(percutaneous or surgical)

urinary diversion
110
What are the3 types of urinary diversion
Indiana Pouch
Kock Pouch
Ureterosigmoidostomy
111
Indiana Pouch
Type of continent urinary diversion
For patients whose bladder was removed or no longer functions
It is made from the terminal ileum and part of the cecum
One way flush valve that has a catheter drain it every 4-6 hours in order to empty it
112
Kock Pouch
Similar to indiana, but has a nipple like valve/stoma - the end of the small intestine is connected to the outside
You need a bowel prep and oral antibiotics before doing this
113
When is a kock pouch contraindicated
IBD - Irritable bowel disease
114
Ureterosigmoidostomy
Continent urinary diversion
ureters attached to sigmoid colon - NOT a continent ostomy
products leave rectum
permanent ostomy and is non reversible
115
What does it mean that uretersigmoidostomy is NOT a continent ostomy
it means there is always something draining from it - and it is the consistency of watery diarrhea
With this ostomy it allows urine to flow through the colon and out of the rectum - voiding goes through the rectum
116
Kidney Transplantation
implanation of human kidney from compatible donor if recipient has irreversible kidney failure
117
How does a kidney transplant cost compared to dialysis
it is 1/3 the cost of dialysis
118

Have in semi fowler and monitor
121
Post Op Kidney Transplant Interventions
Place in semi fowlers position
Monitor patency of Foley cath and gross hematuria and clots, (not expected) --> Notify physician if this occurs
Assess urine characteristic (Starts pink and bloody but gradually returns to normal wihtin days to weeks)
If 3 foley irrigation, monitor to prevent blood clot formation
Note the Foley should be removed ASAP to prevent infection
Maintain protective isolation precautions and monitor for infection
Monitor IV fluids closely for fluid overload or oliguria

*Some anti rejection meds may mask s/s of rejection so you really want to be diligent when assessing
123
Aspects of Client Education with Kidney Transplants
avoid prolonged periods of sitting
recognize s/s of infection and rejection
avoid contact sports
avoid exposure to people with infections
take medications as prescribed and know importance of maintaining immunosuppressive therapy for life
124
What is kidney transplant surgeyr like
sometimes the diseased kidney is left there and ureter is disconnected and attached to a new donor kidney
