Introduction

Correct answer: A. Diet planning and counselling according to individual needs

Explanation: Dietetics is the practical application of nutrition. It involves assessing a person’s needs, planning suitable meals, adapting food choices to health conditions and preferences, and counselling the person about implementation. It is therefore directly related to diet planning and counselling, making option A correct.

Correct answer: C. Giving small, frequent meals

Explanation: Small, frequent meals are generally more acceptable when a patient has a poor appetite. They reduce the pressure of eating a large quantity at one time and can help the patient obtain energy and nutrients gradually. Meals should still be planned according to the patient’s disease, tolerance, and medical advice.

Correct answer: A. They can indicate internal nutritional status

Explanation: Biochemical tests analyse blood, urine, or other body samples to provide objective information about the body's internal nutritional condition. They may help identify deficiencies, excesses, or changes in nutrient metabolism that cannot be judged only by appearance or dietary history. Therefore, option A is correct. Such results should be interpreted with clinical signs, anthropometric measurements, and the person's diet.

Correct answer: A. Because disease condition and activity keep changing

Explanation: Energy requirements during illness depend on factors such as the type and severity of disease, fever, infection, inflammation, wounds, metabolic stress, physical activity, mobility, age, and recovery stage. A patient who is resting may need a different amount from one with fever or increased healing needs. Diet plans must therefore be assessed and adjusted rather than treated as fixed. Option A is correct.

Correct answer: A. Taking nutrition-related action according to an identified problem

Explanation: Nutrition intervention is the planned action taken to address a diagnosed nutrition problem or need. It may include changing the patient’s food intake, providing counselling, modifying nutrients or texture, or coordinating nutrition support. It is more than simply naming a disease; it is a practical step toward improvement.

Correct answer: A. To link the diet with the patient’s medical condition and nutritional needs

Explanation: The central idea of clinical nutrition is that food and nutrient care must be connected with the patient’s medical condition, symptoms, treatment, and nutritional requirements. A suitable diet can support healing, maintain strength, prevent complications, and improve recovery, so planning must remain patient-centred.

Correct answer: A. To assess fluid balance and hydration

Explanation: A patient's water-drinking habit helps the nutrition professional estimate fluid intake and assess the risk of dehydration or excessive fluid consumption. This information is especially relevant during fever, vomiting, diarrhoea, heavy sweating, or kidney and heart conditions. Water intake alone does not determine protein needs, chewing ability, or food allergies, so option A is the most appropriate answer.

Correct answer: B. Clear broth or strained juice

Explanation: A clear liquid diet consists of transparent, low-residue fluids that leave little undigested material in the digestive tract. Examples include clear broth, strained fruit juice without pulp, plain tea, and oral rehydration fluids. Fried, coarse, or solid foods do not meet the definition. Therefore, clear broth or strained juice is the correct answer. Such diets may be used temporarily when easy digestion or limited gastrointestinal stimulation is required.

Correct answer: A. Providing nutrition by bypassing the digestive tract

Explanation: Parenteral nutrition supplies nutrients directly into the bloodstream, usually through intravenous access, instead of passing them through the stomach and intestines. It may be considered when the gastrointestinal tract cannot be used adequately or safely. It requires careful medical monitoring because complications such as infection or metabolic imbalance are possible. Therefore, option A correctly describes bypassing the digestive tract.

Correct answer: B. They show food intake and changes in it

Explanation: Dietary records document what a patient eats and drinks, including approximate amounts, timing, tolerance, and changes in intake. Health professionals can compare the record with nutritional requirements, identify inadequate or excessive intake, and adjust counselling or the diet plan. Records also help monitor progress over time. They do not alter taste or stop treatment, so option B is correct.

Correct answer: D. How often different foods are consumed

Explanation: A food frequency questionnaire records how often selected foods or food groups are consumed over a specified period, such as a week, month, or several months. It is useful for identifying usual dietary patterns and habits rather than measuring one single day precisely. It may also ask about portion frequency and preparation. Therefore, option D is the correct answer.

Correct answer: D. Limit lactose-containing milk and dairy foods according to tolerance

Explanation: Lactose intolerance occurs when the body does not produce enough lactase to digest lactose, the natural sugar in milk. Limiting the amount of milk or other lactose-containing foods, choosing lactose-free products, or using suitable alternatives may reduce symptoms. Many people can tolerate small portions, so complete dairy avoidance is not automatically necessary.

Correct answer: B. It is the study of diet care according to the patient’s condition

Explanation: Clinical nutrition is the application of nutrition science to the care of people who are ill or have special medical needs. It includes assessing nutritional status, identifying nutrition-related problems, planning an appropriate diet, coordinating care with the medical team, and monitoring the patient’s response. Therefore, diet care must be adapted to the patient’s disease, treatment, symptoms, and ability to eat.

Correct answer: B. To make the diet more acceptable

Explanation: Food preferences are important because a diet is more likely to be followed when it includes acceptable, familiar, culturally appropriate, and enjoyable choices. Considering preferences can improve appetite, satisfaction, cooperation, and long-term adherence without compromising medical requirements. The dietitian still balances these preferences with the patient’s condition and nutrient needs. Therefore, option B is correct.

Correct answer: D. It helps the patient remember instructions

Explanation: Written diet advice gives the patient a clear record of foods, portions, timing, preparation methods, restrictions, substitutions, and safety instructions. It reduces confusion after the consultation and allows the patient or caregiver to check the plan while shopping, cooking, and eating at home. It also supports communication and follow-up. Therefore, option D is correct; written advice does not replace the physician or make food costlier.

Correct answer: D. Risk of infection

Explanation: Ignoring food safety can expose a patient to harmful microorganisms, toxins, or contamination. Improper handwashing, unsafe water, undercooking, cross-contamination, and poor storage can cause food-borne illness. Patients may be especially vulnerable because illness or weak immunity can reduce their ability to resist infection. Thus, option D is the correct answer.

Correct answer: D. They are easier to follow

Explanation: Small, specific, achievable goals make dietary behaviour change more manageable. A patient can practise one change, receive feedback, and gradually build confidence before adding another goal. This approach may improve adherence and long-term sustainability, although goals should still be nutritionally appropriate and agreed upon with the patient. Therefore, option D is correct.

Correct answer: C. Ethical and respectful behaviour

Explanation: Confidentiality means protecting private information such as a patient’s diagnosis, nutrition assessment, dietary history, and counselling details. It demonstrates professional ethics, respect for dignity, and responsible care. Maintaining privacy also strengthens trust, which encourages patients to share accurate information needed for safe and individualized nutrition counselling.

Correct answer: C. Eat small meals during the day and follow the prescribed portions.

Explanation: Option C is correct because it gives specific, practical, and measurable advice: eat smaller meals at suitable intervals and follow the prescribed portion sizes. Good diet instruction should be realistic, safe, easy to remember, and appropriate to the patient’s condition. Option A is incomplete because it does not state a limit, while B is unsafe and D provides no therapeutic guidance.

Correct answer: D. The plan may not remain practical or followable.

Explanation: Option D is correct because the cost and availability of foods strongly influence whether a patient can follow a diet plan. If expensive, rare, or unaffordable foods are prescribed without considering the family’s resources, adherence may be poor. A good plan uses nutritious, locally available, culturally acceptable, and affordable choices whenever possible.

Correct answer: B. Some medicines may require particular food timings or precautions.

Explanation: Option B is correct because food and medicines can interact in several ways. Food may change the absorption or effect of a medicine, and some medicines must be taken with food while others require an empty stomach. Asking about this relationship helps the dietitian provide safe advice and avoid preventable treatment problems.

Correct answer: C. Provide simple education and safe alternatives.

Explanation: Option C is correct because fear of food should be addressed through empathetic communication, simple nutrition education, and safe, acceptable alternatives. The dietitian should identify the source of fear, correct misinformation, respect the patient’s culture and preferences, and coordinate care when needed. Stopping all food or ignoring the concern can worsen nutritional risk.

Correct answer: A. Find the reason and make the plan practical

Explanation: The first practical step is to identify why the patient cannot follow the prescribed diet. Barriers may include cost, taste, cultural beliefs, lack of knowledge, poor appetite, side effects, or difficulty with preparation. After understanding the barrier, the dietitian can modify the plan realistically while protecting nutritional needs and medical goals. Blaming the patient or adding restrictions without discussion is neither scientific nor helpful.

Correct answer: C. Clearly identifying the patient's nutrition problem

Explanation: Nutrition diagnosis is the step in which a nutrition professional identifies and describes a specific nutrition-related problem, such as inadequate intake, excessive intake, or difficulty following a prescribed diet. It is different from a medical diagnosis, which identifies a disease. The correct answer is C because it directly refers to recognizing the patient's nutrition problem so that suitable intervention can be planned.

Correct answer: A. The patient shows discomfort after the diet or a worsening condition

Explanation: Immediate review is needed when a patient develops discomfort after eating, cannot tolerate the prescribed plan, or shows a worsening clinical condition. These signs may indicate an allergy, intolerance, inadequate intake, or another safety concern. The dietitian should reassess the patient and coordinate with the healthcare team rather than continuing an unsuitable plan.
