The cafeteria served green beans for lunch starting at 11 a.m. By 1 p.m., the remaining
green beans have become overcooked and mushy. What pigment is found in the green
beans at 1 p.m.?
A. Chlorophyllase
B. Chlorophyll
C. Pheophytin
D. Chlorophyllin
Correct answer: Chlorophyllin
The green pigment found in green beans is known as chlorophyll. This green pigment turns to
bright green in alkaline environments and is known as chlorophyllin. During this chemical
change, the alkaline softens the cellulose, and the hemicellulose is broken down, becoming
mushy.
Green pigment turns to olive green in acid environments and is known as pheophytin.
Chlorophyllase is a plant enzyme that splits off from chlorophyll to form chlorophyllide.
What are the 4 P's of the marketing mix?
A. Packaging, positioning, people, perishables
B. Intangibility, perishability, heterogenicity, inseparability
C. product, place, price, promotion
D. Marking niche, market place, market segmentation, market strategy
,Correct answer: Product, place, price, promotion
A marketing mix is developed to achieve an organization's objectives and satisfy the target
market. The 4 P's of the marketing mix are product, place, price, and promotion.
Once the marketing mix is established, the 7 P's of marketing include product, price, promotion,
place, packaging, positioning and people.
Service marketing includes intangibility, perishability, heterogenicity, and inseparability.
A marketing plan includes the following: marketing niche, marketplace, market segmentation,
marketing objective, marketing strategy, and the marketing mix (4 P's).
During an initial nutrition assessment, an RD identifies that a client is anemic and
encourages her to eat more foods with iron. The RD provides the client with a handout of
high-iron foods, shows her pictures of high-iron foods, and develops a high-iron meal plan
with foods the client prefers. When the client returns for a follow-up nutrition assessment,
she reports that she has increased her consumption of iron-rich foods and has higher
energy levels. The RD praises the client and encourages continuation of the new eating
patterns. What type of change strategy is the RD using?
A. Avoidance learning
B. Positive reinforcement
C. Extinction
D. Positive cause-effect
Correct answer: Positive reinforcement
Positive reinforcement is a behavior modification method that focuses on encouraging repetition
of a certain behavior and provides meaningful attention from a superior.
Avoidance learning is when a client learns to escape undesirable consequences or avoid criticism
,by improving future performance. Extinction focuses on reducing an undesirable behavior until it
goes away, or becomes extinct. Positive cause-effect is a fabricated term.
The hospital is developing a Healthy Eating for Diabetes book for client nutrition
education. The hospital population is low-income and has a low education level, and the
hospital accepts patients without insurance. When creating client nutrition education
written material, what should the reading level be?
3rd grade
8th grade
12th grade
6th grade
Grade: 6th grade
When creating written educational materials, the reading level should be around the 6th grade for
audiences of lower literacy. For the general population, the reading level should be around 8th
grade, for example, for a hospital serving a population with an average education level.
When determining readability, the SMOG index is a useful tool for determining grade level, by
finding the average number of polysyllabic words in a block of text. After conducting a SMOG
index on the written education material, one may choose to set the reading level at a 3rd or 12th
grade level, but for this question, 6th grade level is most appropriate.
Which of the following fruits/vegetables should be washed just before serving?
Cucumbers
Mangos
Carrots
Raspberries
, Correct answer: Raspberries
Mushrooms and berries (strawberries, raspberries, blackberries) should be washed just before
serving because these fruits/vegetables readily absorb water and become mushy.
Other fruits and vegetables, such as cucumbers and carrots, can be washed before storing to wash
away dust and spray residues.
Some fruits and vegetables, such as bananas and mangos, do not require washing because the
skin is not eaten.
If an anthoxanthin is cooked in an aluminum pan, what color will the end product be?
Yellow
Bluish
Colorless
No change
Correct answer: Yellow
Antoxanthins, or flavones, are water-soluble white pigments. An example of a plant rich in
anthoxanthin is the onion. Anthoxanthins are colorless in acid and yellow in alkaline. Aluminum
is an alkaline environment.
Anthocyanin is a water-soluble red, blue, or purple pigment. An example of a plant rich in
anthocyanin is blueberries. Anthocyanins are bright red in acid (such as metals) and bluish in
alkaline.

link between omega-6 consumption and coronary artery disease. She has established her
topic, research, question, and hypothesis. What is her next step in the study?
