Test 2 Flashcards
MNT energy needs for BPD & CLD
25-50% > control
50-85 kcal / kg BW / d (no growth)
120-130 kcal / kg BW / d (growth)
MNT macronut needs for BPD & CLD
protein: provide ≥ 7% kcal
fat & CHO: added to formula after concentrated to 24 kcal / oz–fat provides essential FAs & cals when fluid tolerance & CO2 load is limited–excessive CHOs ↑ RQ & output of CO2
resp. quotient (RQ)
ratio–CO2 expired : vol. of O2 inspired
MNT fluid needs for BPD & CLD
for fluid balance: restrict Na & fluids & use diuretics
when fluids restricted, use parenteral lipids or cal-dense enteral feedings (formulas >24 kcal / oz)
MNT vit & min needs for BPD & CLD
monitor drug-nut interactions
Vit. K for bone development
Vit. A for proper development
adequate stores of Fe, Zn, & Ca due to prematurity
diuretics, bronchodilators, antibiotics, cardiac anti-arrhythmics, & corticosteroids→↑ed urinary losses of min’s, esp. Cl, K, & Ca (resp. acidosis ↑ losses)–def. of Cl or K→muscle weakness & impaired growth
MNT macronut needs for COPD
energy needs ↑ed due to labored breathing–NO overfeeding
protein (15-20% kcal)–1.2-1.7 g / kg dry BW / d–encourage BCAAs–long-term steroids→protein catabolism & gluconeogenesis→ - N2 balance
fat (30-45% kcal)–for hypercapnia, severe dyspnea, or ventilation weaning pts—IV form + hyperlipidemia→inflammation
CHO (40-55% kcal)–↑er RQ→produce more CO2→breathing difficulty ↑→exhaustion→ARF
MNT vit & min needs for COPD
cor pulmonale + fluid restriction→limit Na & fluids
may need K for diuretics
↑ed losses of Cl, K, & Ca from meds→supp
Mg & Ca for muscle contraction & relaxation
inadequate stores of Fe, Zn, Ca, & P due to prematurity→supp
long-term steroids→osteoporosis risk→Ca supp
smokers: +16 mg / d for 1 pack / d
MNT fluid needs for COPD
possible 1° or 2° dehydration
intense sputum & expectoration→body’s hydration ↓→secretion removal ↓ (stay hydrated!)
nut-drug interactions for COPD
- bronchodilators: anorexia & ↓ed K
- expectorants: xerostomia→caries, loss of teeth, gum diseaes, stomatitis, & glossitis, nut. imbalances, wt loss; loss of taste
- corticosteroid: K supp; monitor Vit. D, Ca, K, & Mg; avoid St. John’s Wort; monitor pts at risk for Zn def; avoid immune-enhancing supp’s
MNT macronut needs for CF
3000-4000 kcal / d
protein: 15-20% kcal / d b/c malabsorption
CHO: 45-65% kcal / d (adjust as needed)
fat: 35-40% kcal / d—include essential FAs & fat-sol. vit’s—limits food volume & improves palatability—may have steatorrhea
MNT vit & min needs for CF
H2O-sol. vit’s absorbed better than fat-sol. ones, even those w/ pancreatic enzyme replacement therapy (PERT)
↑ Na b/c losses through sweating, lethargy, vomiting, & dehydration
MNT for Ca kidney stones
fluids: 3 L / d
cranberry juice acidifies urine (for UTIs & struvite stones)
black current juice will alkalize urine & prevent uric acid stones
tea, coffee, beer, & wine ↓ risk of stone formation
protein: moderate animal (.8 g / kg BW)
Ca: do NOT restrict (if restricted, bone min. wasting & ↓ed bone min. density→fracture risk ↑)
oxalates: ~60 mg / d
K: ↓-oxalate fruits & veg’s
Mg: inhibits oxalate formation
Phosphate: excess urine phosphate ↑ Ca-phosphate stone risk
Na: 500 mg Vit. C / d–Vit B6 needed in oxalate met.
MNT for uric acid stones
protein: restrict dietary purines (meat, fish, & poultry) b/c acid production–implement alkaline-ash diet
MNT for cystine stones
maintain alkaline urine pH typically via meds (raise pH to 7.5 via alkaline-ash diet)
avoid excess methionine (fish), which ↑ production of methionine
> 4 L / d of fluids
MNT for struvite stones
long-term antibiotics, surgical removal, & shockwave lithotripsy
