Review
The purpose of a dietary assessment includes all of
the following except:
A) analyze the diet to prevent obesity
B) study the patient’s food habits and snacking
patterns
C) identify the patient who may be at a nutritional and
oral health risk
D) determine the overall consistency of the diet
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Answer
A) Analyze the diet to prevent obesity is
the correct answer.
The dental hygienist does not give
dieting advice when doing a dietary
assessment. The hygienist studies the
food habits and compares them to the
current standards and addresses any
concerns.
