Clinical Nutritionist CCN Clinical Assessment and Nutritional Diagnosis 2

Question 1

What does the subjective global assessment (SGA) primarily evaluate?

Accepted Answer

Medical history, dietary intake, GI symptoms, functional capacity, and physical examination

Answer

SGA is a validated bedside tool that categorizes nutritional status using history (weight change, dietary intake, GI symptoms, functional capacity) and physical examination (fat/muscle wasting, edema).

Question 2

Which dietary assessment method has the highest accuracy for estimating actual nutrient intake over multiple days?

Accepted Answer

Multiple-day weighed food record

Answer

A weighed food record in which the subject weighs all food before eating provides the most accurate quantitative estimate of nutrient intake when conducted over 3-7 days.

Question 3

A serum albumin level below which threshold indicates severe hypoalbuminemia associated with malnutrition?

Accepted Answer

2.1 g/dL

Answer

Serum albumin below 2.1 g/dL indicates severe hypoalbuminemia; values between 2.1-2.8 g/dL suggest moderate depletion, though albumin also reflects inflammation and hydration status.

Question 4

Which method is considered the gold standard for measuring body composition in clinical research?

Accepted Answer

Dual-energy X-ray absorptiometry (DEXA)

Answer

DEXA is the gold standard for body composition measurement, providing precise quantification of fat mass, lean mass, and bone mineral density with low radiation exposure.

Question 5

Handgrip strength measurement is used in nutritional assessment to evaluate which parameter?

Accepted Answer

Skeletal muscle function and sarcopenia risk

Answer

Handgrip strength is a validated surrogate measure of overall muscle strength and is used to screen for sarcopenia and functional decline associated with malnutrition.
