Practice questions
01 Advising a healthy person to improve food habits for preventing heart disease comes under which scope?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Preventive nutrition
Explanation: Nutrition counselling is not limited to treating an existing illness. A healthy person may receive advice about balanced food, fibre, saturated fat, sodium, activity, and healthy body weight to reduce future cardiovascular risk. Since the goal is to prevent disease before it develops, this is preventive nutrition rather than disease treatment alone.
02 Advising a lactating mother on energy, water, and balanced food comes under which scope?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Lactation and maternal nutrition
Explanation: Lactation increases the mother’s needs for energy, fluids, and a balanced supply of nutrients. Counselling should support milk production, maternal recovery, hydration, adequate food variety, and culturally practical choices while avoiding unnecessary restrictions. These needs belong to lactation and maternal nutrition, whereas sports nutrition concerns athletic performance.
03 Making a food list by considering culture, taste, and income is what type of service?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Individualized and practical diet counselling
Explanation: Effective diet counselling must be individualized and practical. Considering culture, taste, income, local foods, cooking facilities, and family habits makes the food list acceptable, affordable, and easier to follow. A single identical list may ignore important barriers and reduce adherence, while photography and promotion do not provide personal nutrition guidance.
04 Modifying a diet plan after getting food-tolerance information from a nurse is an example of what?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Multidisciplinary team-based clinical care
Explanation: The nurse contributes observations about appetite, nausea, vomiting, swallowing, tolerance, and actual intake. The dietitian uses that clinical information to adjust the plan, showing coordinated care among healthcare professionals. This is multidisciplinary team-based clinical care; it is not an isolated decision, a presentation change, or kitchen procurement.
05 Communicating research findings to the community in simple language is an example of which combined scope?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Research and nutrition education
Explanation: Nutrition research becomes socially useful when its findings are translated into understandable, accurate, and actionable messages. Explaining evidence to community members supports informed food choices and healthy practices, while the research provides the foundation for the advice. Therefore, the activity combines nutrition research with nutrition education and communication.
06 Correcting wrong infant-feeding beliefs in a village comes under which scope?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Infant nutrition education and community counselling
Explanation: Correcting harmful infant-feeding beliefs requires accurate education about breastfeeding, complementary feeding, hygiene, meal frequency, safe preparation, and age-appropriate foods. Community counselling also respects local practices while addressing misinformation and referring serious problems. This is an important infant and community nutrition service, not transport, textile, or business work.
07 Making a nutritious menu while reducing food waste in food service is an extension of which scope?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Food-service management
Explanation: Food-service management includes menu planning, nutritional adequacy, budgeting, purchasing, portion control, safe preparation, acceptability, and waste reduction. A nutritious menu that uses resources efficiently therefore extends food-service management beyond cooking alone. The other options have no relationship to institutional meal planning or nutrition.
08 In which situation will a dietitian’s scope depend on team decision with a doctor?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Giving special nutrition support to a critically ill patient
Explanation: Option A is correct because critically ill patients may need enteral or parenteral nutrition, fluid adjustment and careful monitoring of organ function, medication and laboratory values. These decisions involve medical risks and therefore require coordinated work with doctors, nurses and other professionals. This is multidisciplinary nutrition practice.
09 Why is giving even the correct food to the wrong patient a safety issue within scope in a hospital?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Because it can affect both patient safety and the diet order
Explanation: Option B is correct because a diet may be prescribed for a particular allergy, disease, texture, nutrient restriction or procedure. Giving it to another patient can cause an allergic reaction, aspiration, metabolic complication or interference with treatment. Correct patient identification and matching the meal to the authorised diet order are essential clinical food-service responsibilities.
10 How does the scope of clinical nutrition bridge research and practice?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. By applying evidence according to patient need and context
Explanation: Option C is correct because evidence-based practice does not mean copying a research result without thought. The dietitian evaluates the quality and relevance of evidence, then combines it with clinical judgement, the patient’s preferences, culture, resources, diagnosis and goals. This careful translation of research into individual care creates the bridge between science and practice.
11 When is family counselling ethically appropriate within the scope of clinical nutrition?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. When patient consent and confidentiality are respected
Explanation: Option A is correct because family members can support shopping, cooking, feeding and adherence, but the patient remains the centre of care. Counselling should involve the family with the patient’s informed consent, respect privacy and consider decision-making capacity. Information should be shared only when authorised or legally required, never casually or coercively.
12 For clinical nutrition scope to be effective at policy level it should be based on what?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Scientific evidence and public health need
Explanation: Option B is correct because a sound nutrition policy must respond to the actual burden of malnutrition and disease while using reliable scientific evidence. Policymakers also need information about feasibility, equity, cost, culture, food availability and likely outcomes. Rumours, advertising or one person’s preference cannot provide a responsible basis for population-level decisions.
13 Why is the scope of clinical nutrition in a cancer patient not limited only to weight checking?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because food tolerance, treatment effects and nutrition needs are also considered
Explanation: Option A is correct because cancer and its treatments may affect appetite, taste, swallowing, digestion, metabolism and the body’s nutrient needs. Nutrition care therefore considers weight trends, muscle loss, intake, symptoms, treatment effects, food tolerance, laboratory information and patient goals. Weight remains useful, but it is only one part of a holistic assessment and supportive-care plan.
14 How is the scope of clinical nutrition specialized in measuring patient progress?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Assessing diet adherence, health indicators and patient response together
Explanation: Option B is correct because monitoring combines several sources of evidence: adherence to the plan, weight or body-composition trends, symptoms, appetite, tolerance, functional status, laboratory findings and relevant health indicators. Accurate records allow comparison over time and help the dietitian decide whether to continue, intensify or modify the intervention. Guesswork cannot provide reliable evaluation.
15 Under which condition is online counselling scope in clinical nutrition considered safe?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. With identity confirmation, confidentiality and proper assessment
Explanation: Option C is correct because tele-nutrition still requires professional accountability. The practitioner should verify identity, obtain relevant history and consent, use a secure communication system, protect records and determine whether remote assessment is adequate. Red flags or complex conditions may require referral for in-person medical care. Public posts and casual comments cannot ensure safety or confidentiality.
16 How is clinical nutrition scope linked with multiple diseases in an elderly patient?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Making an individualised plan according to appetite, chewing, medicines and diseases
Explanation: Option B is correct because older adults may simultaneously have diabetes, hypertension, kidney disease, swallowing difficulty, poor appetite, dental problems and multiple medicines. A safe plan must balance disease-related restrictions with adequate energy, protein, hydration, texture, enjoyment and the patient’s preferences. Individualised assessment and coordination with the clinical team are therefore essential.
17 The scope of clinical nutrition in supplement advice is linked with which precaution?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Advising after assessing need and safety
Explanation: Supplements should not be prescribed merely because they are popular or advertised. Clinical nutrition first assesses the person’s dietary intake, nutritional requirement, medical condition, possible interactions, dosage and safety. A supplement is recommended only when it is needed and appropriate, while normal wholesome food remains important. Therefore, option D is the scientifically and ethically correct precaution.
18 Where is the scope of clinical nutrition limited in food–medicine interaction?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Advising dietary precautions and coordinating with a doctor
Explanation: A clinical nutrition professional can explain food choices, nutrient restrictions and possible food–medicine concerns, and can communicate with the prescribing doctor. However, independently stopping a medicine, changing its dose or declaring ordinary food to be medicine exceeds the professional boundary. Safe care requires teamwork, referral and respect for medical authority. Thus, option A correctly describes the permitted role.
19 Why is including a patient’s culture an important part of clinical nutrition practice?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because culture affects dietary acceptability and adherence
Explanation: Cultural practices influence the foods a person prefers, avoids, can afford, prepares and accepts socially or religiously. A culturally sensitive clinical dietitian adapts recipes, portions and substitutions without compromising medical requirements. This improves trust, feasibility and long-term adherence. Cultural foods should be modified where necessary, not automatically rejected. Therefore, option A is correct.
20 Which use of media is responsible within the scope of clinical nutrition?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Sharing evidence-based messages and correcting myths
Explanation: Media can extend nutrition education, but communication must be accurate, ethical and understandable. Evidence-based messages can correct myths about supplements, fad diets and miraculous cures without exposing patient identity or promising results that science cannot support. Responsible communication protects the public from harm and encourages realistic healthy behaviour. Hence, option C is correct.
21 How can the scope of clinical nutrition be measured in corporate wellness?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. By improvements in employees’ health habits and food choices
Explanation: A corporate nutrition programme should be evaluated by meaningful outcomes rather than by the number of activities delivered. Useful indicators include healthier food choices, improved meal patterns, participation, physical or biochemical risk improvement when appropriate, and sustained behaviour change. Posters alone do not prove effectiveness, and fear-based methods are unethical. Therefore, option A is the best measure.
22 Why does the scope of clinical nutrition go beyond food distribution during disaster relief?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because nutritional needs, safety, hygiene and vulnerable groups must also be considered
Explanation: Emergency nutrition involves more than distributing calories. Planners must consider the age, illness, pregnancy, disability and cultural needs of affected people, while maintaining safe water, hygiene, storage and preparation. Nutrient quality and equitable access also matter. Simply counting packages can miss serious risks such as contamination or exclusion of vulnerable groups. Thus, option A is correct.
23 What should clinical nutrition emphasise when teaching food-label claims?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Understanding the claim’s scientific basis and nutrition context
Explanation: A health or nutrition claim should be interpreted alongside the ingredient list, serving size, nutrient declaration, product context and available scientific evidence. Marketing language can create a misleading impression even when a statement is technically allowed. Critical label reading helps patients choose suitable foods and avoid exaggerated claims. Thus, option B represents responsible nutrition education.
24 Which strategy should clinical nutrition use when addressing diet myths?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Using scientific information, simple examples and respectful dialogue
Explanation: Myths are corrected most effectively when the professional listens respectfully, identifies the source of the belief, explains the evidence in simple language and offers practical alternatives. Insult or fear may damage trust and cause resistance. Nutrition counselling should support informed decisions rather than promote products. Consequently, option B is the ethical and evidence-based strategy.
25 Institutional menu planning in clinical nutrition depends on which balance?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Nutritional adequacy, cost, hygiene and acceptability
Explanation: An institutional menu must meet nutrient and therapeutic requirements while remaining affordable, hygienically prepared and acceptable to the people who eat it. It also needs practical planning for supplies, labour, portions and cultural preferences. Focusing only on appearance, oil or price ignores essential service responsibilities. Therefore, option A gives the complete and balanced basis for menu planning.
