Study Notes
Nutrition Screening and Assessment
- Nutrition screening is used to identify patients who may be at nutritional risk, diagnose malnutrition, and identify patients who should receive a comprehensive nutritional assessment by an RD.
Electrolytes and Fluid Balance
- Sodium is an electrolyte cation that exists primarily extracellularly.
- Patients with a BMI of 17 and clinical profile (K-2.1, Phos-1.9, Mg-1.1, tachycardia, and fluid retention) may require electrolyte repletion followed by slow advancement of feedings to prevent refeeding syndrome.
Lab Profiles and Acid-Base Balance
- A lab profile with pH-7.3, HCO3-35, and PaCO2-47 may represent respiratory acidosis with compensation.
Therapeutic Diets and Nutrition Support
- A patient with Stage V CKD with HD requires a therapeutic diet with 1.2 gm pro/kg, 50% high biological value, 3-4 gm Na, and restricted fluid intake.
Patient Case Studies: Ruth
- Ruth requires a feeding tube and a method of feeding that provides 1.5 gm pro/kg, with a weight-based calorie goal and fluid intake of at least 2400 mL.
- The MSJ REE formula is used to calculate energy and protein goals: REE = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) - 161.
- Jevity 1.0 is recommended as the tube feeding formula, providing 16% of total calories from protein.
- The goal rate of feeding is 100 mL/hr, with a total of 2400 mL or 2400 kcal/day.
- Based on Albumin levels (2.8) and UUN (10), the protein intake may need to be increased.
Patient Case Studies: Ron
- Ron, a 56-year-old male, requires nutrition support after a hematopoietic stem cell transplant and graft-versus-host disease of the GI tract.
- His nutrition support goals include:
- Energy needs: 3360 kcal/day (MEE x 1.2)
- Protein needs: 178 gm/day (1.8-2.5 gm/kg)
- Fat infusion: 25% of total calories, with a volume of 420 mL over 12 hours
- TPN recommendation: D20AA6.8 in 2.58 L with 420 mL 20% IL over 12 hours, or D20AA6.8 at 110 mL/hr with 35 mL/hr 20% IL.
- Final solution provides 3.06 L fluid, 3353 kcal, and 180 gm pro/day.
