What is the flavanoid in turmeric that has anti-inflammatory properties?

  • Curcumin

  • Quercetin

  • Glutathione

  • Coenzyme Q10

Correct answer: Curcumin

Curcumin is the flavanoid in turmeric that has anti-inflammatory properties.

What should the healthy weight gain range be for a woman, pregnant with twins, whose pre-pregnancy BMI is 21.4?

  • 37-54 lbs

  • 15-25 lbs

  • 25-35 lbs

  • 28-40 lbs

Correct answer: 37-54 lbs

A healthy weight gain range is based on a woman's pre-pregnancy Body Mass Index (BMI) and the number of babies she carries.

A BMI of 21.4 is in the "normal" weight category.

The recommendation for someone with a normal BMI and carrying twins = a gain of 37-54 lbs.

  • Twins and overweight = 31-50 lbs
  • Singleton and overweight = 15-25 lbs
  • Singleton and normal weight = 25-35 lbs
  • Singleton and underweight = 28-40 lbs

83.

Using the Hamwi formula, determine the ideal body weight for a 65-year-old female who is 62 inches tall, weighs 116 pounds, and has a small frame.

  • 99 lbs

  • 105 lbs

  • 121 lbs

  • 106 lbs

Correct answer: 99 lbs

The Hamwi formula computes a person's ideal body weight (IBW) according to the following:

  • Male: 106 lbs for first 5 ft + 6 lbs for each additional inch
  • Female: 100 lbs for first 5 ft + 5 lbs for each additional inch
  • *Subtract 5 lbs for each inch below 5 ft (may vary from 2 to 5 lbs based on institution), and allow +/-10% range for small to large frames for individual differences.

To calculate the IBW for this person, the equation is:

100 lbs + (5 lbs x 2 in.) = 110 lbs

(-10% for small frame) 110 x 0.90 = 99 lbs

The other choices are calculated incorrectly by subtracting only 5%, adding 10%, and using the formula for men.

84.

Which of the following is not a long-term consequence of uncontrolled diabetes?

  • Elevated fasting glucose

  • Neuropathy

  • Retinopathy

  • Nephropathy

Correct answer: Elevated fasting glucose

Long-term consequences of uncontrolled diabetes include neuropathy (peripheral and autonomic damage, such as gastroparesis), retinopathy (leading to blindness), and nephropathy (decreased renal function).

Short-term consequences of uncontrolled diabetes include elevated fasting glucose, elevated 2-hour postprandial glucose, and ≥6.5% HgbA1C.

85.

An outpatient diabetes clinic wants to determine if their nutrition education program is worthwhile in terms of its costs. The cost to run the program includes RD staffing, educational materials, and overhead costs, while the measured outcomes include HgA1C%, diabetes complications, and dietary changes.

Which quality improvement study should be used and why?

  • Cost-benefit analysis because it examines program outcomes in terms of money saved

  • Cost-effectiveness analysis because it determines whether the goal of the intervention is worthwhile in terms of costs

  • Cost-effectiveness analysis because it compares alternatives

  • Cost-benefit analysis because it provides comparisons of alternative courses of action in terms of their costs

Correct answer: Cost-benefit analysis because it examines program outcomes in terms of money saved

A cost-benefit analysis should be used because the goal is to determine whether the nutrition education program is worthwhile in terms of its overall costs. Cost-benefit analysis examines program outcomes in terms of money saved and determines whether the goal of the intervention is worthwhile in terms of costs.

Cost-effectiveness analysis compares alternatives and provides comparisons of alternative courses of action in terms of their costs, financial gains, savings, and effectiveness in obtaining objectives. This analysis would be useful if the goal was to determine which nutrition education program or class was most useful.

86.

In a restaurant, waitstaff greet customers with a smile, take their orders efficiently, and promptly address any concerns. Which term best describes these interactions between the waitstaff and customers?

  • Customer service

  • Foodservice

  • Social marketing

  • Transaction

Correct answer: Customer service

Customer service is the interaction between service staff and customers. It is also the act of helping others.

Foodservice defines and encompasses the entire organization, not just the interaction between staff and customers. Social marketing is using marketing concepts to increase the acceptability of social ideas or practices. Transaction is a distractor.

87.

18 FTEs produced 1,990 meals during a 40-hour week. How many meals were produced per labor hour?

  • 2.76 meals per labor hour

  • 0.36 meals per labor hour

  • 14.47 meals per labor hour

  • 49.75 meals per labor hour

Correct answer: 2.76 meals per labor hour

Meals per labor hour = # meals produced / # hours worked

To solve:

  1. 18 FTEs x 40 hours = 720 hours
  2. 1,900 meals / 720 hours = 2.76 meals per labor hour

88.

A dietitian viewing a patient's blood sugar readings that the patient uploaded from her glucometer to use in educating the patient would be defined as what?

  • Telenutrition

  • Nutrition education

  • Telemedicine

  • Telehealth

Correct answer: Telenutrition

The Academy of Nutrition and Dietetics defines telenutrition as "the interactive use, by a RDN, of electronic information and telecommunications technologies to implement the Nutrition Care Process."

89.

Which of the following is not part of the feedback loop that regulates the creation of thyroid hormones?

  • Pancreas

  • Hypothalamus

  • Pituitary gland

  • Thyroid gland

Correct answer: Pancreas

The hypothalamic-pituitary-thyroid axis (HPT axis) is made up of the hypothalamus, pituitary gland, and thyroid gland. 

The pancreas produces insulin, a hormone that helps regulate blood sugar. It is not involved in the production of thyroid hormones. 

90.

A registered dietitian has developed a survey to assess middle school students' dietary habits and nutritional knowledge. She wants to ensure that the survey genuinely and accurately reflects the concepts she's studying, and not other unrelated factors. Before finalizing the survey, she wants to evaluate a specific type of validity to ensure its effectiveness. Which type of validity is the dietitian most concerned with?

  • Construct validity

  • Behavioral validity

  • Face validity

  • Criterion validity

Correct answer: Construct validity

Construct validity evaluates how well a tool measures the theoretical trait or concept it's designed to measure. It's about ensuring that the tool clearly measures the construct (e.g. "nutritional knowledge") and not other unrelated factors. If the dietitian wants to ensure her survey truly gauges dietary habits and nutritional knowledge without being influenced by external or unrelated factors, she's looking at construct validity.

Face validity comes from pilot testing with the intended audience and finding out if the tool is suitable. Criterion validity determines how well one measure predicts an outcome for another measure. Behavioral validity is a fabricated term.

91.

Which of the following is an example of lobbying?

  • A group of RDs meets with legislators to encourage support of an issue

  • A food service manager informs employees of goals, policies, and responsibilities 

  • Nutritionists present their views in front of a bill's sponsors

  • An appropriations committee provides funding for a nutrition bill

Correct answer: A group of RDs meets with legislators to encourage support of an issue

Lobbying is performing activities aimed at influencing public officials and legislators. An example of lobbying is when a group of RDs meets with legislators to encourage support of an issue.

Orientation is informing employees of goals, policies, and responsibilities. A public hearing is when testimony is heard by a bill's sponsors. An appropriations committee provides money for programs, which attaches funding to legislation. An example would be an appropriations committee providing funding for a nutrition bill.

92.

Which of the following is not a key characteristic of functional medicine?

  • Use of herbal supplements

  • Focus on root cause of dysfunction

  • Use of evidence-based treatment

  • Consideration of the patient as a whole system

Correct answer: Use of herbal supplements

Functional medicine is an evidence-based type of practice that takes into account the body as a whole system. It focuses on the patient as that whole system, not just a disease state. It aims to treat the root cause of dysfunction, not just treat the dysfunction directly. 

Herbal supplements could be used within functional medicine practice, but that is not a key characteristic of functional medicine. 

93.

Which of the following is the correct arrangement of meat grades from highest to lowest quality?

  • Prime, Choice, Select, Standard

  • Prime, Choice, Standard, Select

  • Select, Prime, Standard, Choice

  • Choice, Prime, Select, Standard

Correct answer: Prime, Choice, Select, Standard

Meats are graded from highest to lowest: Prime, Choice, Select, Standard.

94.

On average, how much water does a person lose per day due to insensible water loss?

  • 1.0 L

  • 0.5 L

  • 1.5 L

  • 2.0 L

Correct answer: 1.0 L

On average, a person loses between 0.8 and 1.2 liters of water per day due to insensible water loss. Insensible water losses include transepidermal diffusion (water that passes through the skin and is lost by evaporation) and evaporative water loss through the respiratory tract—in other words, water lost through skin and breathing.

A sensible water loss can be seen, felt, and measured; for example, urine output.

95.

Which of the following health care professionals is not allowed to participate in the nutrition screening process?

  • All health care team members can participate

  • Dietetic technician

  • Registered nurse

  • Registered dietitian

Correct answer: All health care team members can participate

All health care team members can participate in the nutrition screening process and serve a supportive role in this preliminary step. The health care member that performs this step can vary, but it is usually done by an RN upon the patient's admission.

The nutrition screen is not part of the ADIME process, which is conducted by the RD. 

96.

Which of the following is false about functional foods?

  • All functional foods are altered versions of natural foods

  • Functional foods do not have a legal definition

  • Nutraceuticals are functional foods

  • The FDA oversees functional food marketing

Correct answer: All functional foods are altered versions of natural foods

Functional foods are defined as any food that provides health benefits beyond that of their nutrient content. This includes naturally occurring foods.

Functional foods are not defined by law. They may also be called nutraceuticals. The FDA oversees marketing claims of functional foods.

97.

According to the ADA, which of the following is a "reasonable accommodation" to make a workplace and dining area accessible to a person with disabilities?

  • Installing wheelchair ramps

  • Installing elevators

  • Widening aisles to at least 46"

  • Widening doorways at a company with 10 employees

Correct answer: Installing wheelchair ramps

The Americans with Disabilities Act (ADA) went into effect in 1994 for companies with 15 or more employees. It provides general guidelines for implementing reasonable accommodations for persons with disabilities in the workplace and dining areas. Accommodations may include installing ramps, widening doorways, and lowering shelves and counters. 

Installing elevators might be an undue hardship and therefore an unreasonable accommodation due to its nature and cost.

Aisles must be at least 36" wide to accommodate persons with wheelchairs.

Companies with fewer than 15 employees are not mandated by the ADA to implement reasonable accommodations.

98.

Which of the following groups of fruits and vegetables is considered climacteric?

  • Peach, banana, apple

  • Grapes, melon, lemon

  • Watermelon, pomegranate, grapes

  • Grapefruit, cherries, peppers

Correct answer: Peach, banana, apple

Climacteric fruits and vegetables ripen post-harvest. Examples of these include peaches, pears, bananas, apples, and tomatoes.

Non-climacteric fruits and vegetables ripen before harvest. Examples of these include grapes, melon, peppers, and citrus fruits.

99.

Which of the following is an example of an entitlement program?

  • SNAP

  • FMNP

  • WIC

  • TEFAP

Correct answer: SNAP

The Supplemental Nutrition Assistance Program (SNAP) is an example of an entitlement program. SNAP provides coupons and electronic debit cards, known as electronic benefit transfer (EBT) cards, to the eligible needy. Entitlement programs are programs funded by Congress for any person who qualifies due to level of income or other eligibility requirements. 

The Farmers' Market Nutrition Program (FMNP), Women, Infants, and Children (WIC), and The Emergency Food Assistance Program (TEFAP) are examples of nonentitlement programs. Nonentitlement programs compete for funds through the congressional appropriation process and establish eligibility requirements for recipients.   

100.

Which of the following does not have a direct and significant impact on determining longevity in humans?

  • Basal metabolic rate

  • Access to healthcare

  • Environment

  • Genetics

Correct answer: Basal metabolic rate

Basal Metabolic Rate (BMR) is a measure of energy expenditure and does not directly affect longevity.

Longevity depends on lifestyle, environment, genetics, and access to healthcare.
