WGU C787 NUTRITION AND FOOD SAFETY
EXAM 2026 |140 QUESTIONS WITH
ACCURATE SOLUTIONS
1. If a patient is diagnosed with hypertension, which dietary
approach would you recommend based on the DASH principles?
A. Eliminating all fats from the diet regardless of their type
B. Increasing red meat consumption and limiting fruits
C. Incorporating more fruits, vegetables, and whole grains while reducing
sodium intake
D. Focusing solely on high-protein foods and avoiding all carbohydrates
Rationale:
The DASH (Dietary Approaches to Stop Hypertension) diet emphasizes fruits,
vegetables, whole grains, lean proteins, and low-fat dairy while limiting sodium. This
pattern has been clinically proven to lower blood pressure and improve cardiovascular
health. Eliminating all fats or carbohydrates is unnecessary and can cause nutrient
imbalances. Red meat intake is typically limited due to saturated fat content.
2. Which of the following conditions is the physical discomfort
resulting from the lack of food?
A. Starvation
B. Food insecurity
C. Hunger
D. Poverty
Rationale:
Hunger refers specifically to the physical sensation caused by not having enough food
to eat. Food insecurity is a broader socioeconomic condition describing limited access
to adequate food. Starvation is a severe, prolonged lack of food leading to metabolic
damage. Poverty may contribute to hunger but is not a physiological condition itself.
,3. Identify an obese BMI.
A. BMI < 18.5
B. BMI > 30.0
C. BMI 18.5–24.9
D. BMI 25.0–29.9
Rationale:
A BMI greater than 30.0 is classified as obesity according to CDC and WHO standards.
This category is associated with increased risk for chronic diseases such as diabetes,
heart disease, and hypertension. A BMI between 25.0 and 29.9 is considered
overweight, not obese. BMI values below 18.5 indicate underweight.
4. Describe the significance of household food security status in
relation to public health.
A. Household food security status is irrelevant to public health concerns
B. Household food security status focuses solely on food waste management
C. Household food security status reflects the ability of individuals to access
sufficient, nutritious food, impacting overall health and well-being
D. Household food security status only measures food quantity
Rationale:
Household food security is a critical public health indicator because it affects
nutritional status, disease risk, and health outcomes. Insecure households often
experience higher rates of malnutrition and chronic illness. It measures both
availability and access to nutritious food, not just quantity. Public health programs rely
on this data to guide interventions.
, 5. What are two infections that can be transmitted through the
fecal-oral route?
A. Shigellosis and Cholera
B. Salmonella and E. coli
C. Listeriosis and Campylobacter
D. Hepatitis A and Norovirus
Rationale:
Hepatitis A and Norovirus are classic fecal-oral pathogens transmitted through
contaminated food, water, or poor hygiene. These infections spread easily in food
service and community settings. Proper handwashing and sanitation are essential
prevention strategies. While other listed infections may involve foodborne
transmission, they are not primarily fecal-oral.
6. If a public health official is creating a nutrition program, how is
the Estimated Average Requirement (EAR) used?
A. Ignoring EAR and focusing only on individuals
B. Determining food safety standards
C. Setting maximum nutrient limits
D. Identifying average nutrient needs of a population to guide dietary
planning
Rationale:
The EAR represents the intake level estimated to meet the needs of 50% of a specific
population group. It is primarily used for assessing and planning nutrient intakes at the
population level. EARs are not meant to define individual requirements or upper intake
limits. Public health programs rely on EAR data to prevent nutrient deficiencies.
7. Discuss the nutritional differences between skim milk and full-fat
milk regarding protein and calcium.
