time and type of fluids consumed . type amount of special foods . preparation of foods and fluids.
physical assessment nutrittion
hair brittle, poor wound healing, lack of subucutaneous muscle wasting, irregular cardio vascular HR, BP, enlarged spleen and liver. general weakness or imparied cordination.
anthropometric tools
Height, weight illness and injury can put risk for malnutriotn. ( weight changes from usual. same time and frequency. , BMI ideal 18.5-24.5 overweight 25-29. obese greater than 30, BMI= weight KG/ height m2
clinical values fluid amounts I+O
adults 2,000 to 3,00 mL (2-3L) per day
total average output
1,750-3,00 mL/day
protein levels
albumin 3.5-5 g/dL
prealbumin
prealbumin levels are used to measure effectiveness of total parenteral nutrition. expected range 15-36 mg/dL. less than 10,7 mg/dL severe malnutrition.
nitrogen balance
relationship between protein breakdown (catabolism) and protein synthesis( anabolism)
Record protein intake in grams over 24 hrs and divide by 6.25
record nitrogen excretion in urine over 24 hr and add 4 g
subtract nitrogen output from intake
24 protein intake /6.25 = nitrogen intake.
24 hr urinary urea nitrogen +4 g= total nitrogen output
nitrogen intake-total nitrogen output+nitrogen balance
neutral NB indicated adequate nutritional intake
anoretic medications
surpress appetite and reduce food intake. when combined with excersise program and can result in weight lose.
Orlistant- prevent digestion of fats
Lorcaserin-stimulates serotonin receptors in the hypothalamus in the brain to curb appetite.
phentermine-topiramate-suppresses the appetite and induces feeling fo stiety.
