NURS1602 Final Exam With
Complete Solution
Define the scope and science of nutrition - ANSWER Nutrition science is an
interdisciplinary field that studies dietary intake and behavior, as well as the
nutrients and constituents in food, their use by the body, and their influence
on human health
Distinguish between the different types of DRI values and what each
represents - ANSWER RDA: recommended dietary allowance
--Recommended nutrient intake levels that meet the daily needs and
decrease risk of chronic disease in almost all healthy people
UL: tolerable upper intake
--Maximum amount of nutrient allowed that has been proven to have no risk
of side effects
Understand/explain the basis of the scientific method and how it is used in
nutrition research - ANSWER Nutrition employs the scientific method.
Research design and consistency across studies are important determinants
of the quality, reliability, and applicability of study findings
Hypothesis, measurements and data gathering, and interpretation of results
Describe the three types of experimental design and the primary advantages
of each - ANSWER Randomized controlled trial
--participants recruited and assigned randomly to control group and
,experimental group; patients blind to treatment; data analyzed to see
differences between control and experimental group (placebo)
--Results are directly applicable to humans
Epidemiologic Studies
--observes the associations between variables in a population; can never
establish cause and effect because neither variable is manipulated or
controlled (no intervention)
--Can assess complex interactions amongst genetics, behavioral, and
environmental factors
Experimental Model System
--Animal experiments, cell culture studies, and biochemical analysis are used
as model systems to understand how nutrients in our diet affect
physiological and health in humans; much nutrient information from these
studies
--Can be performed when human studies would be too costly, unethical, or
require an impractical length of time to complete
Describe reliable sources of nutrition information - ANSWER Registered
dietitians (RD) is the standard legal definition for someone having extensive
knowledge and training in foods, nutrition, and dietetics
Identify at least five determinants of eating behavior - ANSWER Experiences
with food(familiar, preferences)
Social Factors(cultural norms, social norms, social setting)
Individual Factors(Perceptions, beliefs, attitudes)
, Environmental Factors(Cost, accessibility, convenience)
Psychological Factors(mood, stress)
Biological Factors(hunger, taste, pleasure)
Discuss factors that may contribute to dietary and weight changes during the
college years - ANSWER
Fallacy of freshman 15 - ANSWER Around 2-4 pounds
Characteristics of diets of late adolescence and early adulthood - ANSWER
More fast food, processed food, sugary beverages, fewer vegetables, whole
grains, and milk(low in calcium, iron and fiber)
Define moderate alcohol consumption and what is considered a standard
drink - ANSWER Standard drink: 14 grams of pure alcohol(12 ounces of beer,
5 ounces of wine, 1.5 ounces of distilled liquor)
Moderate consumption for men: 2 standard alcoholic drinks per day
For women: 1 standard alcoholic drink per day
Describe how alcohol is absorbed and metabolized in the body - ANSWER
Absorbed in stomach and small intestine
Metabolized in the liver into fat for energy
Alcohol stays in the blood and body fluids until the liver is able to metabolize
it(one ounce per hour); intoxicating effects depend on gender, weight, food
intake, use of drugs/medicine, and genetics
Discuss the definitions of and potential consequences of heavy drinking and
