Chapter 2: Nutrition Care Process Flashcards
an in-depth evaluation of both objective and subjective data related to an individual’s food and nutrient intake, lifestyle, and medical history.
Nutrition Assessment
It is an ongoing, nonlinear and dynamic process that involves data collection and continual analysis of the patient/client’s status compared to specified criteria.

Five Components of Nutrition Status
- Food/nutrition-related history
- Anthropometric measurements
- Biochemical data, medical tests and procedures 4. Nutrition-focused physical findings
- Client history
Food/nutrition-related history
• Diet history
• Food and beverage intake
• Medication/supplement use
• Enteral and parenteral intake
refers to the daily eating pattern of an individual, including specific foods and calories consumed and relative quantities.
Dietary Intake Data
a detailed daily record of the food and drink one consumes over a certain period of time.
Food Diary
consist of a finite list of foods and beverages with response categories to indicate the usual frequency of consumption over the time period queried.
Food Frequency Questionnaire
a structured interview intended to capture detailed information about all foods and beverages consumed by the respondent in the past 24 hours, most commonly, from midnight to midnight of previous day.
24 - hour diet recall
Provide either an estimated or actual determination of some aspect of body composition.

to determine body fats stores and nutritional status. The most common measurement site is triceps skin fold (TSF). Measurements can also be performed in subscapular and suprailiac skin folds.
Skinfold thickness
provides information on skeletal muscle mass.
Mid-arm and mid-arm muscle circumferences (MAC)
determines the percentage of red blood cell of whole blood. It reflects the body’s iron supply. It is the iron component of the blood that transports oxygen.
Hemoglobin
a ratio of the volume of red blood cells to the volume of all these components together, called whole blood
Hematocrit
a protein that regulates iron absorption. It can be measured by the total iron-binding capacity (TIBC) (the amount of iron which it can bind). Serum iron is the amount of transferrin-bound iron
Transferrin
Measures visceral protein status
Total lymphocyte count
Protein malnutrition has been shown to decrease immune function. This diminished reaction to antigen is called
anergy
It is an indicator of visceral protein status. Because it has a long half-life (about 20 days), it is not an indicator that detects subtle or early changes in nutritional status.
Albumin
Also called thyroxine-binding prealbumin is the transport protein for thyroxine and retinol-binding protein. The half-life is 24-48 hours so it is an excellent value to monitor the effects of recent nutritional support and changes in nutritional status.
