Practice questions
01 If a dietitian plans a diet using seasonal foods for a low-income family, which feature of nutrition practice is demonstrated?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Practical and affordable diet planning
Explanation: Using seasonal foods can reduce cost and improve availability while still allowing a balanced diet. For a low-income family, the dietitian must combine nutrient needs with budget, local supply, cooking resources, and family preferences. This practical, resource-sensitive approach is affordable diet planning.
02 If a dietitian advises healthy habits to a person whose reports are normal, which scope is demonstrated?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Health promotion and prevention
Explanation: Nutrition care is not limited to treating an existing disease. Advising a person with normal reports about balanced eating, physical activity, appropriate portions, and healthy routines can maintain wellness and reduce future risk. This preventive and health-promoting role is correctly described as health promotion and prevention.
03 If food consistency is modified along with a therapeutic diet in a hospital, which combined scope is involved?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Therapeutic diet and food service
Explanation: Hospital diets may be modified in nutrient composition and in physical consistency. A patient may need a liquid, soft, minced, or pureed form because of swallowing, chewing, digestive, or medical problems. Coordinating the therapeutic prescription with safe preparation and service represents therapeutic diet and food service.
04 If a dietitian plans for a high-risk patient using information from the doctor, nurse, and family, which scope is demonstrated?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Multidisciplinary clinical nutrition service
Explanation: High-risk patients often have complex medical, dietary, functional, and social needs. Information from doctors, nurses, and family helps the dietitian understand treatment, symptoms, care capacity, and home circumstances. Working with this team is a multidisciplinary clinical nutrition service rather than isolated counselling.
05 If a nutrition expert provides local, inexpensive, and nutritious options in a shopping list, which service is involved?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Practical diet counselling
Explanation: A shopping list translates nutrition advice into practical food choices. By selecting local, affordable, and nutrient-rich items, the dietitian helps the client manage budget, availability, household needs, and health goals. This is practical diet counselling; laboratory analysis and industrial production address different professional tasks.
06 If a dietitian modifies a patient’s diet plan after follow-up, which skill is demonstrated?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Clinical monitoring and plan modification
Explanation: Follow-up provides evidence about how the patient is responding to the prescribed diet. The dietitian may review symptoms, intake, weight, laboratory findings, adherence, and tolerance, then adjust foods, quantities, consistency, or timing. This continuing cycle of monitoring and adjustment is clinical monitoring and plan modification.
07 If a dietitian maintains a complete history and confidentiality while giving online advice, what quality of nutrition service is demonstrated?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Safe digital nutrition service
Explanation: Online nutrition counselling still requires appropriate assessment, accurate documentation, informed communication, and protection of personal health information. Maintaining a complete history supports safe professional decisions, while confidentiality protects the client’s privacy. These practices together describe a safe digital nutrition service rather than casual online communication.
08 If a nutrition expert suggests reducing the fat content of a food product, which scope is involved?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Food product improvement
Explanation: Recommending a reduction in fat content applies nutrition knowledge to the composition and improvement of a food product. The expert may consider energy value, the type of fat, taste, texture, shelf life, consumer needs, and regulatory requirements. This product-oriented nutrition role is food product improvement.
09 If a dietitian selects food by considering both chewing difficulty and a patient’s nutrition needs, which scope is involved?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Special diet and clinical nutrition
Explanation: A patient who has difficulty chewing may need a modified texture, but the food must still provide adequate energy, protein, vitamins, and minerals. Selecting meals that meet both functional limitations and nutritional requirements is a clinical dietetic decision. It therefore belongs to special diet planning within clinical nutrition.
10 If a nutrition expert suggests changes in school meals based on research, which scopes are connected?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Research, child nutrition, and food service
Explanation: Research-based changes to school meals connect evidence with the nutritional needs of children and the practical management of food service. Research helps identify effective improvements; child nutrition guides nutrient and age appropriateness; food-service considerations address procurement, preparation, safety, cost, and delivery. Thus, option D is correct.
11 Which is the broadest explanation of the scope of clinical nutrition and dietetics?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. It extends to treatment, prevention, education, research, food service, digital service and community health
Explanation: Clinical nutrition and dietetics is a multidisciplinary field. It includes nutritional assessment, therapeutic diet planning, patient counselling, disease prevention, food-service management, research, digital counselling, and community work. Because it serves individuals and populations in many settings, option B gives the most complete description of its scope.
12 If a dietitian plays different roles in hospital, community, food service, and digital counselling, what does this prove?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. The scope of dietetics is multi-sectoral and expands according to changing needs
Explanation: A dietitian may work in hospitals, public-health programmes, institutional food services, schools, private practice, and tele-nutrition. These roles require different skills but share the goal of improving nutrition and health. The variety of settings demonstrates a broad, multi-sectoral scope rather than a narrow kitchen or single-disease role.
13 Which statement best explains the broad scope of clinical nutrition and dietetics?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. It extends to patient care, community education, food service, research and policy
Explanation: The field combines scientific nutrition knowledge with practical health care. Professionals assess patients, design therapeutic diets, educate communities, manage food services, conduct research, and contribute to health planning. Thus, its scope is multidimensional and connected with both individual care and population health; option B is the complete statement.
14 In which example is the expert scope of clinical nutrition most clearly visible?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Making a diet intervention based on the patient’s disease, investigations and food habits
Explanation: Expert clinical nutrition begins with assessment of diagnosis, laboratory findings, symptoms, nutritional status, usual intake, preferences, and constraints. The dietitian then individualises the intervention and monitors its response. Giving everyone the same food ignores clinical differences, while disclosure of private information is unethical and plate decoration is not expert care.
15 Which answer correctly states the scope of a dietitian in a multidisciplinary health team?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Linking the patient’s nutrition needs with the complete care plan
Explanation: Within a multidisciplinary team, the dietitian contributes specialised nutrition assessment, estimates requirements, recommends suitable food or nutrition support, educates the patient, and communicates with doctors and nurses. The dietitian does not independently prescribe medicine, manage accounts, or disclose confidential information. Option B accurately describes coordinated nutrition care.
16 Why is the scope of clinical nutrition considered to begin with nutritional assessment?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Because the patient’s needs are unclear without assessment
Explanation: Nutritional assessment gathers relevant information such as diagnosis, body measurements, laboratory data, symptoms, food intake, allergies, preferences, socioeconomic conditions, and functional ability. This information identifies risks and guides a safe, realistic, individualised plan. Without assessment, advice may be unsuitable or unsafe, so option C is correct.
17 How is the scope of clinical dietetics visible in therapeutic diets?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Modifying quantity, texture and nutrient composition according to disease and condition
Explanation: A therapeutic diet adapts ordinary food to the patient’s medical and nutritional requirements. Changes may involve energy, protein, sodium, fibre, carbohydrate, fluid, meal frequency, texture, or route of feeding. The modification depends on diagnosis and tolerance, is coordinated with the health team, and is monitored; it is not universal fasting or taste-only menu design.
18 What is the expert scope of clinical nutrition in hospital food service?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Ensuring that the safe, prescribed diet reaches the correct patient
Explanation: Hospital food service must translate the authorised diet order into safe meal production and delivery. This includes accurate identification, checking allergies and restrictions, preventing cross-contact, maintaining hygiene and temperature control, and confirming that the correct tray reaches the correct patient. These responsibilities protect patients and support treatment; decoration alone is not clinical nutrition.
19 Why does the scope of clinical nutrition extend to discharge counselling?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Because adherence to the diet plan and follow-up care are needed at home
Explanation: Discharge counselling ensures continuity between hospital treatment and home care. The dietitian explains the prescribed diet, portions, meal timing, foods to include or avoid, medicine–food precautions, warning signs, and follow-up requirements in language the patient and family can use. This improves adherence and reduces preventable complications. Diet remains important after discharge, so B is correct.
20 In which situation does the scope of clinical nutrition extend to special nutrition support?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. When a person cannot safely take normal food
Explanation: Special nutrition support is considered when oral intake is unsafe, inadequate, or impossible, such as in severe swallowing difficulty, critical illness, or certain gastrointestinal conditions. After assessment and team discussion, enteral feeding may use the gastrointestinal tract, while parenteral nutrition uses intravenous access when necessary. It must be individualised and monitored; therefore C is correct.
21 Why is the scope of clinical nutrition important in food-label education?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. So people can understand nutrient information and choose foods correctly
Explanation: Food-label education develops practical nutrition literacy. People learn to examine serving size, energy, protein, sugars, sodium, saturated fat, allergens, ingredients, and relevant claims instead of relying only on advertising. This helps patients and families select foods consistent with therapeutic or preventive goals. Labels do not replace professional advice, but understanding them supports informed and safer choices.
22 The expert scope of clinical nutrition in the community is most linked with what?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Nutrition-risk identification, health education and prevention
Explanation: Community nutrition extends professional care beyond the individual clinic. It involves identifying groups at nutritional risk, screening and referral, providing culturally suitable education, supporting healthy food practices, and preventing deficiency and chronic disease. Effective work respects privacy and local resources. Therefore, option B correctly connects clinical nutrition expertise with community health rather than entertainment or disclosure of records.
23 How can the scope of clinical nutrition be linked with policy making?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. By providing technical input for nutrition guidelines and public-health programmes
Explanation: Nutrition professionals can contribute evidence-based technical knowledge to policy development. They may help interpret dietary data, formulate nutrient recommendations, design food-based guidelines, establish standards for institutional meals, plan supplementation programmes, and evaluate population outcomes. Such work should use reliable evidence, equity considerations, and transparent monitoring. Therefore, C correctly represents the policy-related scope of clinical nutrition.
24 Which question best links the scope of clinical nutrition with research?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Which dietary pattern improves health outcomes?
Explanation: Clinical nutrition research investigates relationships between dietary intake, nutrition interventions, disease risk, recovery, quality of life, and measurable health outcomes. A well-designed study may compare dietary patterns while controlling for relevant factors and collecting valid evidence. The other questions concern unrelated subjects, so option A is the only research question relevant to clinical nutrition and dietetics.
25 With which ethical condition is the scope of clinical nutrition applied in private practice?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. With evidence-based advice, confidentiality and follow-up
Explanation: Private practice does not remove professional responsibility. A dietitian should assess the client, use current scientific evidence, explain realistic benefits and limits, protect personal information, obtain appropriate consent, document care, and arrange follow-up. Miracle claims, using identity for promotion, and identical plans without assessment can harm clients and violate ethical practice. Thus C is correct.
