Q

End Stage Kidney Disease -> Dialysis: What is Hemodialysis

A

They need to have access to run this. Can include permacath or a permanent access

54
Q

End Stage Kidney Disease -> Dialysis: What is a permacath

A

Can be tunneled, or permanently tunneled in chest.

55
Q

End Stage Kidney Disease -> Dialysis: What is a permanent access that is placed for hemodialysis?

A

This is either a fistula or a graft.

56
Q

End Stage Kidney Disease -> Dialysis: How does the fistula work?

A

They take an artery and a vein and combine them. Wait for them to future. By putting them together, the vein becomes bigger.

57
Q

End Stage Kidney Disease -> HemoDialysis: Why does the vein become bigger over time?

A

Become the machines have to run at a high rate

58
Q

End Stage Kidney Disease -> HemoDialysis: What is a Synthetic Vascular Graft?

A

They have a synthetic piece of tubing connecting the artery and vein.

59
Q

End Stage Kidney Disease -> HemoDialysis: What is the important thing to keep in mind when using fistula or graft?

A

You have to assess them for a thrill and bruit.

60
Q

End Stage Kidney Disease -> HemoDialysis: What is a thrill?

A

You have to feel for a thrill. Will feel the vibration, will be pulsating

61
Q

End Stage Kidney Disease -> HemoDialysis: What is a Bruit?

A

You have to listen for this. Turbulent blood flow

62
Q

End Stage Kidney Disease -> HemoDialysis: What happens if they don’t have thrill or bruit?

A

Notify physician immediately because patient will not be able to run on dialysis

63
Q

End Stage Kidney Disease -> Hemodialysis: What nursing intervention and precaution must you take for this patient?

A

There can be no peripheral sticks in that extremity. No blood draws, IVs, or blood pressure.

64
Q

End Stage Kidney Disease -> Hemodialysis: Why should you not take blood pressure on the affected extremity?

A

It will damage the fistula or graft

65
Q

End Stage Kidney Disease -> Hemodialysis: How does Dialysis work?

A

Removed blood for cleaning -> Blood Pump with Anticoagulant -> Dialysis Machine -> Airtrap and Air Director -> Clean blood infused

66
Q

End Stage Kidney Disease -> Hemodialysis: What type is usually seen in a patient?

A

Permacath or a Graft. The problem with fistula is that they take a few weeks to fully form and mature. They may also have bad vascular access.

67
Q

End Stage Kidney Disease -> Hemodialysis: What occurs inside of the dialysis machine?

A

Diffusion and Osmosis takes plce here. Toxins removed. Extra fluid removed. It is basically an artificial kidney

68
Q

End Stage Kidney Disease -> Peritoneal Dialysis: What is this?

A

Good option for patients that don’t want to do hemodialysis. Can do this at home.

69
Q

End Stage Kidney Disease -> Peritoneal Dialysis: What was the older school method before cycler was developed?

A

Simply drain solution into peritoneal cavity. That dwells within cavity and then pulls out extra fluid and toxinx. And then drained through drainage bag.

70
Q

End Stage Kidney Disease -> Peritoneal Dialysis: What should be seen within drainage bag?

A

White to straw like color. DOn’t want to see cloudy because they indicates infection. Don’t want to see brown because that indicates that catheter may have possibly punctured bowel..

71
Q

End Stage Kidney Disease -> Peritoneal Dialysis: Where is the catheter placed?

A

Within the peritoneal cavity and that stays there permanently after placement.

72
Q

End Stage Kidney Disease -> Peritoneal Dialysis: WHat happens when patients choose to do their dwelling?

A

Solution bag is hooked up and hung down so that it can drain.

73
Q

End Stage Kidney Disease -> Peritoneal Dialysis: How does this work in simple terms?

A

They fill, dwell, and drain sequence for those patients.

74
Q

End Stage Kidney Disease -> Peritoneal Dialysis: Where is the dialysis bag and drainage bag placed?

A

Dialysis is hung up high so it can drain into peritoneum

Drainage bag is hung low so fluid can flow out. Is effluent because its mixed with toxins and fluid

75
Q

End Stage Kidney Disease -> Peritoneal Dialysis: How to tell when they are done?

A

Patient will notify nurse and then nurse will disconnect. Nurse will be notified when they are ready to be hooked up again.

76
Q

End Stage Kidney Disease -> Peritoneal Dialysis: What is the method seen now?

A

The cycler. Patients hook themselves up to this at night and it cycles all night.

77
Q

AKI: What is this?

A

There has been injury to kidney. And acute. There is a rapid loss of renal function due to damage to kidneys

78
Q

AKI: What was this called before?

A

Acute renal failure

79
Q

AKI: What changes occur in the body because of this?

A

Metabolic Acidosis

Fluid/Electrolyte Imbalance

80
Q

AKI: This process is usually related to what?

A

A specific cause

81
Q

AKI: What are the three main types of causes?

A

Pre-Renal
Intra
Post

82
Q

AKI: What does Pre-Renal refer to?

A

Anything that is impairing blood flow getting ot the kidney. HEart cannot get blood flow down to the kidney

83
Q

AKI: What can cause blood flow to not get to kidneys?

A

Patient can be hypotensive, volume depleted (hypovolemic, dehydrated), shock, sepsis, impaired cardiac function.

Something is going on within heart/body.

84
Q

AKI: What happens in the body when the kidneys are dehydrated?

A

The kidneys aren’t getting the blood that they need. That is what cuases this injury

85
Q

AKI: What does Intra-Renal refer to?

A

Damage to the glomeruli or kidney tubules within the nephron of the kidney. Happening inter-renally.

86
Q

AKI: What medications can cause problems to the kidney?

A

Antibiotics, aminoglycosides, NSAIDSs .

87
Q

AKI: What other problems can cause intra-renal problems?

A

Infections, Crush Injury because myoglobulins get released

88
Q

AKI: Example of crush injury?

A

Arm got caught in a press. Have brutal injury to arm but muscle release the myoglobulin enzyme which goes to the kidney and plugs in the renal .

89
Q

AKI: What diagnostic exam can occur in hospital that can cause this?

A

CT with contrast. Contrast is a really big nephrotoxic agent. Can cause neuropathy.

90
Q

AKI: What can we do as nurses during intra-renal stage?

A

Make sure we hydrate them to help them buffer kidneys like bicarb.

91
Q

AKI: Patient at risk during intra-renal when creatinine is at what level?

A

2

92
Q

AKI: What occurs during Post-Renal AKI?

A

This pertains to anything that happens after kidneys.

93
Q

AKI: What problems does Post-Renal occur?

A

Kidney stone past kidney that blocks urine flow. Have back flow into kdiney

BPH, causing black flow

UTI, patient may not be able to empty bladder

94
Q

AKI: In simple terms, what is happening in post-renal

A

there is an obstruction that is causing pressure on the kidney and decreases GFR.

95
Q

AKI: How many phases are there for this

A

4

96
Q

AKI: What occurs in the first phase?

A

Initiation - The initial assault

97
Q

AKI: What is the second phase

A

Oliguria period. Urine starts to drop. 0.5mL/kg per hour. Kidney starts to lose some of function

98
Q

AKI: What serum changes occur in second phase

A

Serum Creatinine increased
BUN Increased
Potassium increased

Electrolyte Imbalance and hold onto toxins.

99
Q

AKI: What changes will we see on tele for high potassium?

A

Peaked T waves ,

100
Q

AKI: What should we be doing during second phase?

A

Treat whatever is causing this. If hypotensive, give fluids. If on antibiotics, take antibiotic away.

If post-renal cause like UTI, antibiotic to treat UTI

101
Q

AKI: What occurs in the third phase?

A

Diuresis. We start to have gradual increase in urine output. GFR recovers, potassium starts to go to normal,

Patient is starting to correct

102
Q

AKI: What must we do during third phase?

A

Monitor this patient closely.

103
Q

AKI: During third phase, how do we treat high potassium?

A

Can give Kayexalate . Can be given orally or rectally.

104
Q

AKI: How does Kayexalate work>

A

Reduces the content of potassium. Basically binds to stool and patients poop it out.

105
Q

AKI: At what level could you give kayexalate ?

A

When potassium is at like 5.7, 5.8. Not showing EKG changes yet and can give this to lower it.

106
Q

AKI: What to do with Potassium is at 6.5 and they are starting to have PVCs, dysrhythmias

A

You will give them insulin. It will push potassium back into cell and lowers the potassium level within body.

107
Q

AKI: What must you give with insulin?

A

D50 as well. This is so you don’t bottom the patients blood sugar.

108
Q

AKI: What occurs in the fourth phase?

A

Recovery phase, patient is recovering.

Lab values returned to normal

109
Q

AKI: How long may fourth phase take?

A

3-12 months to recover. And they may still have a little drop in their GFR.

110
Q

ESKD - Meds, Hemodialysis: How will there lab values be the day of dialysis?

A

Worse than what is was the day before. Typically dialyzes 3x per week

111
Q

ESKD - Meds, Hemodialysis: What levels will you see on the day of dialysis?

A

Elevated Potassium, BUN, Creatine, and Phosphorus

112
Q

ESKD - Meds, Hemodialysis: Why would Phosphorus be elevated?

A

They are opposite of Calcium. As phosphorus goes up, calcium goes down.

113
Q

ESKD - Meds, Hemodialysis: What will be done since phosphorus is elevaed?

A

Will be given phosphorus and calcium binders. One being PhosLo.

114
Q

ESKD - Meds, Hemodialysis: When is PhosLo given?

A

With a meal. Allows medication to be most effective.

115
Q

ESKD - Meds, Hemodialysis: Why are calcium supplements given?

A

Like tums, it will bring calcium levels up and phosphorus levels down.

116
Q

ESKD - Meds, Hemodialysis: What is Renvela?

A

This is used to prevent hypocalcemia that has been caused by high phsophorus levels. Gets phorphorus levels down.

117
Q

ESKD - Meds, Hemodialysis: What is important to know with phosphorus binders?

A

They must be given with meals.

118
Q

ESKD - Meds, Hemodialysis: Why may EPO be given??

A

TO help stimulate RBC production.

119
Q

ESKD - Diet - Hemodialysis: What type of diet will they be on?

A

Low protein diet because protein is hard for the kidneys to process.

120
Q

ESKD - Diet: What type of protein can they can?

A

High biologic protein. Like dairy, meat, because that’s what necessary for nutrition.

121
