Nutrition Assessment/ Data Collection Flashcards
Diet History consist of:
-Time, type, amount of food eaten from breakfast, lunch, dinner, snacks. Including any kind so of drinks.
-Also type of diet
-Allergies
-Medications/ Supplements
Tools to determine nutritional status
-Anthropometric Tools: Weight, Height, BMI
-Clinical Values: I&O, Protein levels, Pre-albumin, Nitrogen Balance
Anthropometric: Ideal Body weight
Female: 45kg (100lbs) for first 152cm (5ft), and 2.3kg (5lbs) for each additional 2.5 cm(1in)
Male: 48kg (106lbs) for the first 152 cm, and 2.7 (6lbs) for each additional 1in.
Weight loss indicating severe malnutrition in starvation or chronic disease
> 5%/ month
7.5%/3m
10%/ 6m
20%/ 1y
Severe malnutrition medication for acute or injury disease
> 2%/wk
5%/1m
7.5%/3m
How do we read the measurement of height?
To the nearest 0.1 cm or 1/8 inch
What is a healthy BMI
18.5-24.9
Prealbumin
-can measure malnutrition risk for critically ill patients and reflects acute changes rather than gradual changes
-Can be used to measure efficacy of TPN
-Expected Range 15-36
-<10.7 indicate protein-calorie malnutrition & presence of inflammatory process
Nitrogen Balance Formula
- 24 hr protein intake/ 6.26= Nitrogen Intake (g)
- 24 hr urinary urea nitrogen +4g= Total Nitrogen Output
- Nitrogen output-nitrogen intake = Nitrogen Balance
Hormones that can be a risk factor for obesity
Leptin & Gherlin
Expected Waist in Obese
Females: >88.9 cm (35in)
Males: >101.6cm (40in)
Waist to hip ratio
-Can be used to predict CAD
-indicate fat in abomen
F: 0.8+
M:0.95 +
Anoretic Medications
Suppress appetite and reduce food intake
Orlistat
Prevents fat digestion
AE: Oily discharge, de. Vitamin and food absorption, fecal incontinent, dec. Bile flow
Albumin
-Dec level indicate malnutrition, liver, or kidney disease
Expected range: 3.5-5
