MNT Flashcards
Thiamine Deficiency
Wernicke-Korsakoff syndrome- allcoholic liver disease
Diet for hepatic failure
If not comatose: 1-1.5 g pro/kg
30-35 kcal/kg
30-35% fat w MCT oil if needed
Adding BCAA and decreasing aromatic amino acids
Cholecystectomy
Surgical removal of gall bladder
Bile secreted from liver directly into intestine
Pancreatitis
Inflammation with edema
*premature activation of enzymes within pancreas leads to autodigestion
Acute pancreatitis
Put pancreas to rest-withhold all feeding,maintain hydration
Progress as tolerated to low fat diet
Elemental enteral nutrition into jejunum may be tolerated
Chronic pancreatitis
PERT- pancreatic enzymes orally with meals and snacks to minimize fat malabsorption from lack of pancreatic lipase
Parenteral B12 and antacids may be needed
To avoid pain: avoid large meals with fatty foods and alcohol
What is cystic fibrosis
Disease of exocrine glands- secretion of thick mucus that obstructs glands and ducts
Chronic pulmonary disease, pancreatic enzyme deficiency, high perspiration electrolyte levels, and malabsorption result
Treatment for cystic fibrosis
PERT with meals and snacks
High protein- 15-20% kcal –> malabsorption due to pancreatic deficiency
High kcal- 110-200% of normal needs
Unrestricted fat
Liberal in salt
Age appropriate doses of water soluble vitamins and minerals
Supplement water-soluble forms of fat soluble vitamins
Fat soluble vitamin concern for cystic fibrosis
Vitamin a and e
Mostly a-poorly absorbed even with oral enzymes
Normal levels for:
LDL
Total cholesterol
HDL
40 (M) >50 (F)
Diet for atherosclerosis
Increase complex cho–> body converts cholesterol into bile; thus decreasing cholesterol levels
HTN
> 140 systolic- heart in contraction
90 diastolic- in relaxation
Obesity major factor in cause and treatment
Thiazide diuretics
May induce hypokalemia
DASH diet
Recommended for HTN
Whole grains, fruits and vegetable, low fat dairy, poultry and fish, moderate sodium, limit etoh, decrease sweets
Heart failure
Low na as needed (2-3 g) Dash diet, fluid restriction and needed
- 2 g pro stable
- 37 g pro depleted
High homocysteine levels
Independent risk factors for coronary heart disease
Proximal convoluted tubule
Major nutrient resorption
Loop of Henle
Water and sodium balance
Distal tubule
Acid base balance in kidneys
Vasopressin (ADH)
Hormone From hypothalamus
Elevates blood pressure
Renin
Hormone that acts as vasoconstrictor
Elevates blood pressure
Erythropoietin (EPO)
Hormone stimulated by kidney stimulates bone marrow to produce RBC
Renal disease
Decreases globular filtration rate and creatinine clearance (Urine tests)
Increases serum creatinine and BUN (blood test)
Renal solute load
Solutes exerted in 1 L urine
*mainly measures nitrogen (60%) and sodium
Renal calculi
Kidney stones
1.5-2 L of fluid redesign to dilute urine
Calcium oxalate stones
Adequate calcium to bind oxaloacetate
Low oxalate diet (dark leafy Greene, chocolate, strawberries, nuts, beets
Uric acid stones
Alkaline ash/ acid ash diet
Prevent acidic stones- alkaline ash by adding cations -vegetables fruits
Prevent alkaline stones- create acid ash: increase anions by adding meat
AKI/ acute renal failure
Oliguria-urine output <500ml
Azotemia- increase urea in blood
Associated with trauma
Diet therapy for AKI
.6-.75 g pro/kg. increase as GFR returns to normal to 1.2-1.5 g/kg
25-35 kcal/kg
Nephrosis symptoms
Albuminuria hyperlipidemia
Nephrosis nutrition therapy
Protein restriction .8-1.0 g/kg
Fat restriction- ~30%
35 kcal/g
High complex cho
CKD
Moderate/ GFR <25 0.6 pro/kg
ESRD
Retention of nitrogen metabolizes
HBV protein
Goal: control edema/prevent deficiencies
HD nutrition
1.2 g pro/kg
30-35 cal/kg
2-3 g potassium
800-1000 mg phosphorus
Peritoneal dialysis nutrition
1.2-1.3 g pro/kg SBW
30-35 kcal/kg
Potassium unrestricted
800-1000 mg phosphorus

Rapid acting insulin
Aspart novolog lispro humalog
Take 5-15 min before eating
Duration 4 hr
Short acting insulin/ regular
30-45 minutes before meal
1 unit covers 10-15 g
Duration 3-6 hr
Intermediate a ting insulin NPH
Onset 2-4 he
Duration 10-18 hr
Include bedtime snack of cho and protein
Long acting insulin
Glargine lantus determir levemir. Onset 2-4 hr. duration 18-24 hr
Insulin secretagogues
Glucotrol
Promote insulin secretion
Biguanides/ metformin/ glucophage
Enhance insulin action
Supress hepatic glucose production
Thiazolidinediones/ actos
Improve peripheral insulin sensititivity
Postprandial or reactive hypoglycemia
Overstimulation of pancreas or increase insulin sensitivity; blood glucose falls below normal 2-5 hr after eating
- goal is to prevent marked rise in blood glucose that would stimulate more insulin
- avoid simple sugars/ 5/6 small meals a day and spread cho throughout day
Addison’s disease
Absence of adrenal hornones
Hypoglycemia sodium loss and tissue wasting
Diet: High pro frequent feelings high salt
Hyperthyroidism
Elevated t3 and t4
Increased BMR leading to weight loss
Diet-increase kcal
Hypothyroidism
T4 low, t3 normal
Decreased BMR leading to weight gain
Diet: weight reduction
Endemic goiter
Inadequate iodine intake
Diet: iodized salt, free of goiteogens (cabbage family)
Galactosemia
Missing enzyme that would have converted galactose-1-PO4 into glucose-1-PO4
treated solely by diet- galactose and lactose free
**no drugs
No organ meats MSG extenders milk whey casein curds dates bell peppers
Urea cycle defects
Unable to synthesiZe urea from ammonia
Ammonia accumulation
Diet: protein restriction to lower ammonia
PKU
Missing enzyme- phenylalanine hydroxylase- which would convert phenylalanine into tyrosine
Diet: low in phenylalanine, avoid aspartame
Need for phenylalanine decreases with age and infection
Glycogen storage disease
Deficiency if go oar 6 phosphatase in liver
Impairs gluconeogenesis and glycogenolysis
Liver can’t convert glycogen ito glucose leading to hypoglycemia
