Free Registered Dietitian MCQ Questions and Answers — Questions and Answers

Question 1: The best vegetables for preventing cancer are those that contain thiols. There are thiols in:

Food with blue, blue-red and violet pigments
Flax seed, oats and barley
The cabbage family (Correct answer)
Prunes and dried fruits

Correct answer: The cabbage family

Vegetables belonging to the cabbage family, also known as cruciferous vegetables, are rich in sulfur-containing compounds called glucosinolates. When these vegetables are prepared or digested, glucosinolates are converted into biologically active compounds like isothiocyanates and indoles, which are types of thiols or related sulfur compounds. These compounds are well-known for their potent anti-cancer properties, making cruciferous vegetables like broccoli, cabbage, and kale excellent choices for cancer prevention.

Question 2: Which supplement might a patient who has had their stomach removed need?

Vitamin B6
B12 (Correct answer)
Zinc
Copper

Correct answer: B12

The stomach produces intrinsic factor, a glycoprotein essential for the absorption of vitamin B12 in the small intestine. When the stomach is removed (gastrectomy), the production of intrinsic factor ceases. Without intrinsic factor, dietary vitamin B12 cannot be absorbed, leading to a deficiency. Therefore, patients who have undergone a gastrectomy typically require lifelong vitamin B12 supplementation, often via injection or high-dose oral supplements.

Question 3: Which activity should a production manager devote the most time to?

Directing and controlling (Correct answer)
Planning and organizing
Organizing and directing
Organizing and controlling

Correct answer: Directing and controlling

In a production management role, directing involves guiding and motivating employees to achieve production goals, while controlling involves monitoring performance, comparing it to standards, and taking corrective action. These two functions are critical for ensuring efficient operations, maintaining quality, and meeting deadlines in a production environment. While planning and organizing are important initial steps, the ongoing day-to-day responsibilities of a production manager heavily involve overseeing execution and ensuring adherence to plans.

Question 4: You may learn more about the frequency of nutrition-related health issues in the following:

Nutrition Screening Initiative
Nationwide Food Consumption Survey
Healthy People 2011
NHANES III (Correct answer)

Correct answer: NHANES III

NHANES (National Health and Nutrition Examination Survey) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. It combines interviews and physical examinations, collecting extensive data on diet, health conditions, and biomarkers. NHANES III, specifically, provided a comprehensive snapshot of nutrition-related health issues in the U.S. population, making it a key source for understanding their frequency and prevalence.

Question 5: The following is the first stage in ensuring a top-notch curriculum for clinical dietetics practice:

Constructing a tool to gauge the workload of clinical dietitians
Clinical staff productivity in comparison to national averages
Reviewing current standards of practice (Correct answer)
Monitoring the level of documentation in medical records

Correct answer: Reviewing current standards of practice

To develop a high-quality curriculum for clinical dietetics, it is essential to first understand the foundational knowledge and skills required for competent practice. This involves reviewing the current Standards of Practice (SOP) and Standards of Professional Performance (SOPP) set by professional organizations like the Academy of Nutrition and Dietetics. These standards define the minimum expectations for dietitians and serve as the blueprint for curriculum development, ensuring graduates are prepared for real-world clinical roles.

Question 6: A dietitian needs knowledge of the following to suggest nutrition management to a patient with end-stage renal disease who is receiving hemodialysis:

Patient's usual carbohydrate intake
Patient's intake of iron pre-admission
Specific gravity of the urine
Serum potassium level (Correct answer)

Correct answer: Serum potassium level

Patients with end-stage renal disease (ESRD) on hemodialysis often have impaired kidney function, leading to an inability to excrete excess potassium. High serum potassium levels (hyperkalemia) can be life-threatening, causing cardiac arrhythmias. Therefore, monitoring serum potassium is crucial for dietitians to provide appropriate dietary recommendations, such as limiting high-potassium foods, to prevent dangerous electrolyte imbalances in these patients.

Question 7: What is the temperature at which fats smoke?

Above 525 degrees F
Above 500 degrees F
Above 442 degrees F (Correct answer)
Above 350 degrees F

Correct answer: Above 442 degrees F

The smoke point of a fat or oil is the temperature at which it begins to break down and produce smoke, indicating the degradation of its fatty acids. While specific smoke points vary widely depending on the type of fat and its refinement, many common cooking oils have smoke points in the range of 375-450°F. The option 'Above 442 degrees F' represents a general high smoke point, characteristic of oils suitable for high-heat cooking, and is the most appropriate choice among the given options.
