Domain II: Nutrition Care for Individuals and Groups Flashcards
Nutrition Care Process
standardized, consistent structure and framework used to provide nutrition care. This is different from standardized care, which infers that all patients receive the same care
Steps of nutrition care process
ADIME:
assessment, diagnosis, intervention, monitor, evaluate
Critical thinking
integrates facts, informed opinions, active listening and observations. a reasoning process where ideas are produced and evaluated. includes ability to conceptualize, think rationally, think creatively, be inquiring, and tink autonomously
Nutrition screening
use of preliminary nutrition assessment techniques to identify people who are malnourished or at risk for malnutrition
Who can conduct a nutrition screening?
all health care members can participate, brief 5-10 minutes
Nutrition screening reviews:
client’s history, lab results, weight, physical signs
For screening to be effective, the mechanism must be accurate based on:
specificity: can it ID patients without a condition
sensitivity: can it ID those who have the condition
Cultural competence
the ability to provide care to patients with diverse values, beliefs and behaviors and tailor delivery to meet their social, cultural and linguistic needs
Nutrition risk screening requirements of the Joint Commission
nutrition risk identified in hospitalized patients
within 24 hours
at intervals during stay
does NOT mandate method of screening
Nutrition Screening tools include:
SGA: Subjective Global Assessment
MNA: Mini Nutritional Assessment; 65+years old
NSI: Nutrition Screening Initiative; elderly
GNRI: Geriatric Nutritional Risk Index
MST: Malnutrition Screening Tool; acute hospitalized adults
NRS: Nutrition Risk Screening; med-surg
MUST: Malnutrition Universal Screening Tool
Nutrition Assessment critical thinking skills include:
- Observe verbal/nonverbal cues that can guide effective interviewing methods
- Determine appropriate data to collect
- Select tools and procedures and apply in valid, reliable ways
- Distinguish relevant from irrelevant, and important from unimportant data
- Validate, organize and categorize the data
Nutrition Assessment components: review, cluster, identify
REVIEW data for factors that affect nutritional and health status
Data is CLUSTERED for comparison with characteristics of a diagnosis: food/nutrition related history, lab/medical tests, nutrition-focused physical findings, anthropometrics, client history
Indicators are compared to IDENTIFIED STANDARDS and criteria for interpretation and decision-making. Indicators are clearly defined markers that can be observed and measured, also used to monitor and evaluate progress towards nutrition outcomes. Nutrition care criteria are what indicators are compared against.
Documentation includes:
date and time, pertinent data and comparison with standards, patient’s perceptions, values and motivation related to problem, changes in patient’s level of understanding, behaviors, outcomes, reason for discharge
Dietary intake assessment, analysis
- diet history-present patterns of eating. Do not ask leading questions
- food record-food diary, record of everything eaten in a specific period of time
- 24-hour recall-mental recall of everything eaten in previous 24 hours, clinical setting (underreporting and overreporting concerns)
- food frequency lists-how often an item is consumed. Community setting. Quick way to determine intakes of large numbers of people
Pertinent medical and family history
provides insight into nutrition-related problems

Estimates desirable body weight
F: 5’=100# + 5# for each inch
M: 5’=106# + 6# for each inch
small frame: subtract 10%
large frame: add 10%
Amputations: entire leg=16%; lower leg with foot=6%; entire arm=5%; forearm with hand=2.3%

% weight change
stresses significance of weight change; assess nutritional risk
(usual-current)/usual *100
significant weight loss: 10% within 6 months
tricep skinfold thickness (TSF)
measures body fat reserves; measures calorie reserves
standard: male 12.5 mm, female 16.5 mm
arm muscle area AMA

BMI body mass index
compares weight to height
1. weight in kg divided by height in meters squared; or weight in pounds divided by height in inches squared X703
2. healthy adult: 18.5-24.9
healthy for most elderly: 24-29
overweight: 25-29
obese: 30+
3. BMI for age charts starting at 2 years old
Waist circumference
M > 40, F > 35 is independent risk factor for disease
best for assessing risk, predicts central adiposity
Waist to hip ratio
differentiates between android and gynoid obesity
WHR of 1.0 or greater in men, 0.8 or greater in women is indicative of android obesity and an increased risk for obesity-related diseases (diabetes, hypertension)
BIA bioelectrical impedance analysis
