22 Questions
Which component is NOT considered in the nutritional assessment?
Physical activity level
What does nutritional status refer to?
The body's nutrient stores and metabolism of energy and nutrients
What does nutritional risk refer to?
Risk of having nutrition-related health problems
What is the purpose of nutritional screening?
To quickly identify individuals with nutritional risks
Which component is NOT considered in nutritional screening?
Height and weight measurements
What is the primary goal of nutritional assessment?
To identify patients needing nutritional support
Why is malnutrition associated with increased morbidity?
It exacerbates the disease state
What is used to assess body size, weight, and proportions in anthropometry?
Height, weight, circumferences, and skinfolds
Which of the following is NOT a component of body composition?
Delayed hypersensitivity
When is knee height measurement recommended for obtaining height data?
When unable to stand straight or have spinal deformities
What can involuntary weight loss predict?
Risk of functional impairment
What does Mid-upper arm circumference (MAC) assess?
Subcutaneous adipose tissue
Which of the following is true about mid-upper arm muscle circumference (MAMC)?
MAMC is corrected for subcutaneous fat and is insensitive to small changes in muscle.
Which of the following reflects sub-cutaneous adipose tissue stores and is a better indicator of total body fat than a single skinfold measurement?
Mid-upper arm fat area (MAFA)
What does a waist circumference of >102 cm in men and >88 cm in women indicate?
High risk of cardiovascular disease and type 2 diabetes.
Which technique measures impedance to a low-frequency electrical current and estimates fat mass, fat-free mass, and total body water?
Bioelectrical impedance (BIA)
Which method is recognized as a gold-standard for bone density and a reference method for body composition?
Dual energy X-ray absorptiometry (DXA)
Which measure reflects muscle, bone, and subcutaneous fat, but is not sensitive to changes in muscle?
Mid-upper arm circumference (MAC)
How is the mid-upper arm muscle area (MAMA) related to changes in muscle?
MAMA is more sensitive to changes in muscle than MAMC.
What does a high BMI with low waist circumference indicate in terms of health risk?
Low risk of cardiovascular disease and type 2 diabetes.
What is the main limitation of bioelectrical impedance (BIA) as a body composition measurement technique?
Influenced by hydration status.
What does a waist : hip ratio >1.0 for males indicate?
High risk of cardiovascular disease.
