31
Q

A

-MI, arrhythmias, numbness/tingling in hands, death

32
Q

Side effects of low K+

A

weakness

33
Q

Tx if TGs are elevated?

A
  • Reduce refined CHOs, alcohol
  • Add omega-3
  • Reduce BW, exercise
34
Q

Typical lipid patterns in PD?

A
  • Normal Chol
  • High TG
  • Low HDL
35
Q

Why does the creatinine level increase in proportion of LBM breakdown? Why does this change with ethnicity?

A

As it is a product of LBM breakdown

-In African Americans, they have more LBM and therefore are expected to have higher creatinine levels

36
Q

Why abnormal lipid values in dialysis?

A

-Dextrose absorption from dialysate and protein losses into the PD contribute to impaired TG clearance

37
Q

How can a patient compensate for a “salt outing”?

A

By reducing fluid until next dialysis (less hypovolemia)

38
Q

Why may the nutritional diagnosis be due to inadequate food intake?

A
  • Physiological factors (N/V, dysgeusia)
  • Psychological factors (Emotional distress, anxiety)
  • Social barriers (limited income, inability to prepare foods at home)
39
Q

Why may the aetiology of systemic inflammation be related to?

A
  • Dialysis
  • Fluid status/volume overload
  • GI bacterial overgrowth
  • Failed kidney transplant
40
Q

Endocrine disorders associated with uremia?

A
  • Hyperparathyroidism
  • Hyperglucagonemia (Increase glucagon, more gluconeogenesis and glycogenolysis leading to increased BG and insulin resistance)
  • Resistance to the actions of insulin and IGF-1
41
Q

What does metabolic acidosis result in?

A

Increased protein catabolism

42
Q

When does renal bone disease develop?

A

In the early stages of CKD

43
Q

Why do patients with CKD have decreased Ca absorption (2)?

A
  • Altered metabolism of vitamin D

- Inability to excrete phosphate or hyperphosphatemia

44
Q

What does suboptimal calcium and phosphate regulation result in?

A
  • Decreased calcium, or hypocalcemia

- Hyperparathyroidism and renal osteodystrophy

45
Q

What results in secondary hyperparathyroidism?

A
Failure of the endocrine function of the kidneys to
produce calcitriol (1,25 - dihydroxy cholecalciferol)
46
Q

How should secondary hyperparathyroidism be treated?

A

Supplement with active form of Vit D: to increase
calcium absorption and raise serum calcium level and
suppress PTH secretion

47
Q

How should hyperphosphatemia be controlled through diet? What are key offending items?

A
  • Restrict to Phos of 12 mg/kg/day ORR 15 mg/gPro/day

- Dairy, meat, fish, poultry, legumes, bits, bran, cola, chocolate, beer**

48
Q

Other ways to control hyperphosphatemia?

A
  • Use phosphate binders (Sevelamer –> Renagel –> Calcium free)
  • Avoid aluminum containing binders
  • Take binders with food
49
Q

High calcium and phosphate solutes result in what?

A

-Metastic calcification in soft tissue areas, and can lead to renal osteodystrophy

50
Q

Aluminum hydroxide as a phos binder?

A
  • Increases plasma aluminum in patients with HD and PD

- Aluminum is toxic at low concentrations - linked to dementia

51
Q

Calcium based salts as a phos binders?

A
  • Not to be used in hypercalcemia

- Contributes to calcium deposit functions

52
Q

Sevelamer (RENAGEL or RENVELA) as a phos binder?

A
  • Safe due to low absorption
  • Lowers LDL
  • Gi disturbances do not use in bowel obstruction
53
Q

Lanthanum (Phosrenol) as a phos binder?

A
  • Lanthanum accumulation can become a problem

- Expensive

54
Q

____ is a clinical consequence of CKD

A

Anemia

55
Q

What is anemia caused primarily by?

A

Decreased production of the EPO hormone in the kidney

56
Q

Secondary causes of anemia?

A
  • Residual blood loss in the dialyzer
  • Inflammation due to infection and co-morbid conditions
  • Hyperparathyroidism can be adjunctive cause
57
Q

Treatment with anemia?

A
  • Treat with EPO injections and adequate iron from IV dextran
  • Return blood to patient as much as possible
  • Treat hyperparathyroidism
  • Avoid blood transfusions which may help prevent iron overload and antibody production which may prevent successful transplantation later
58
Q

Why is constipation common in dialysis?

A
  • Low fluid intake
  • Inactivity
  • Use of calcium containing phos binders
  • F/V avoidance due to k content
  • Low fibre food choices
59
Q

What can severe constipation lead to?

A

Impaction and bowel perforation

60
Q

How should we treat constipation?

A
  • Add foods high in fiber content
  • Increase fluid intake if possible
  • Add fibre in form of psyllium hydrophillic mucilloid (Metamucil)
  • Use stool softener (Docusate Sodium/Colace)
61
Q

During dialysis, how is BP affected?

A

Causes hypotension

62
Q

What does food ingestion during dialysis cause?

A

-Decreased constriction of resistance vessels in certain vascular beds, especially splanic beds - which can last for 2 hours

63
Q

Guidelines regarding food ingestion and dialysis?

A

-Avoid food just before and during dialysis if prone to hypotension

64
Q

Diabetics not prone to hypotension may eat what during dialysis?

A
  • Low fat meal, or use small CHO snack food; fruit, crackers

- Avoid a hypoglycemic episode
