Nutrition

Correct answer: B. Unintentional weight loss and low food intake

Explanation: Unintentional weight loss and reduced food intake are important warning signs of possible malnutrition. They may indicate inadequate energy or protein intake, illness-related metabolic stress, swallowing difficulty, poor appetite, or problems with digestion and absorption. Such findings should prompt timely nutrition screening and, when indicated, a complete assessment rather than being ignored.

Correct answer: A. Protein deficiency

Explanation: Calories describe energy intake, but they do not guarantee adequate protein. Protein supplies amino acids needed for muscle maintenance, tissue repair, enzymes and immune functions. A patient may consume enough energy from carbohydrates or fats while still having inadequate protein, leading to weakness or poor recovery. Protein intake, clinical signs and other medical causes should therefore be assessed first; option A is correct.

Correct answer: B. Micronutrient deficiency despite energy intake

Explanation: Hidden hunger is a form of malnutrition in which a person may consume enough calories, feel full or even have a normal body weight, yet lack essential vitamins and minerals such as iron, iodine, vitamin A or zinc. It can impair growth, immunity, learning and work capacity without obvious signs of starvation. Thus, option B gives the correct meaning.

Correct answer: C. Energy-dense but nutrient-poor diet

Explanation: An energy-dense diet provides many calories in a relatively small amount of food, often because it contains substantial fat or refined carbohydrate. If it supplies little fibre, vitamins and minerals, it is nutrient-poor despite its high energy value. Such a pattern can contribute to constipation, micronutrient deficiencies and unhealthy weight gain. Therefore, option C is correct.

Correct answer: A. They may contain more sodium, free sugar and unhealthy fat, but less fibre

Explanation: Many highly processed foods are formulated with substantial sodium, free sugar, saturated fat or trans fat, while their fibre and micronutrient content may be limited. Frequent intake can therefore increase energy density and lower overall diet quality, contributing to risks such as obesity, hypertension and poor blood-glucose control. Processing itself is not always harmful, but foods with this nutrient profile should be limited. Hence A is correct.

Correct answer: D. They make quantity instructions practical and followable

Explanation: Household measures translate an abstract quantity into an object the patient uses every day. Specifying one bowl, half a bowl or two teaspoons makes portion instructions easier to understand and reproduce at home than using unfamiliar weights alone. Consistent household measures support portion control, accurate implementation and better adherence, although the dietitian should define the approximate size of the utensil when precision is important. Hence D is correct.

Correct answer: A. Making the diet plan sustainable and practical for long term

Explanation: An early improvement may not last if the patient cannot continue the diet. The expert should identify barriers such as cost, availability, taste, culture, schedule, symptoms, and family support, then modify the plan so it is affordable, acceptable, practical, and nutritionally adequate over the long term. Sustainable adherence is essential for lasting benefit.

Correct answer: A. Checking quantity, quality, variety, hygiene, tolerance and adherence

Explanation: Good nutrition cannot be judged by one visible feature of food. A comprehensive assessment considers the amount and quality of nutrients, variety of food groups, hygiene and safety, tolerance of the patient, cultural suitability and actual adherence. Looking at all these factors gives a more accurate picture of nutritional well-being.

Correct answer: A. Review food variety and the risk of micronutrient inadequacy

Explanation: Normal laboratory values provide useful information, but they do not always reveal early or future dietary inadequacy. A monotonous diet may lack particular vitamins, minerals, fibre or protective food components. The expert should review food-group variety, intake patterns and risk factors, then provide practical improvements without unnecessary restriction.

Correct answer: A. Protein, energy and micronutrient quality

Explanation: Adequate quantity does not guarantee adequate nutrition. Fatigue and delayed wound healing may indicate insufficient protein, energy availability, iron, zinc, vitamin C, or other micronutrients, although medical causes must also be considered. Assessment should examine the quality and variety of the diet, absorption, illness-related needs, laboratory findings, and clinical signs rather than relying only on the amount of food eaten.

Correct answer: A. Future nutritional risk caused by prolonged low food intake

Explanation: A normal blood report reflects the tested indicators at that moment and does not guarantee that future intake will remain adequate. Persistently poor appetite can reduce energy, protein, vitamin, and mineral intake, gradually deplete body stores, and increase the risk of undernutrition. The expert should review dietary history, weight trend, symptoms, functional status, and clinical condition, then provide appropriate support. Blood tests are useful, but they must be interpreted alongside actual food intake and appetite.

Correct answer: A. Risk of micronutrient deficiency

Explanation: Body weight reflects size or mass, but it does not reveal whether the diet supplies all essential vitamins and minerals. A monotonous diet may provide enough calories while lacking iron, folate, vitamin A, vitamin B12, calcium, zinc, or other micronutrients. Therefore, the assessment should review food groups, dietary variety, symptoms, relevant clinical findings, and—when indicated—laboratory results.

Correct answer: C. Adequacy of protein and micronutrients

Explanation: Healing requires more than calories. Protein supplies amino acids for collagen formation, tissue repair, immune function, and maintenance of lean tissue. Micronutrients such as vitamin C, vitamin A, zinc, iron, and copper also support collagen synthesis, immunity, oxygen transport, and cell growth. The assessment should review protein quality and amount, micronutrient-rich foods, absorption, disease, and other clinical factors.

Correct answer: C. Iron-rich food and better absorption

Explanation: Diet counselling for many cases of iron-deficiency anaemia focuses on iron-rich foods such as legumes, green leafy vegetables, meat, eggs, or fortified foods, according to the person's diet. Vitamin C-rich foods can improve non-haem iron absorption, whereas tea or coffee taken with meals may reduce it. The underlying cause still requires medical evaluation.

Correct answer: C. So that health claims are scientific and not misleading

Explanation: Food and health claims can influence consumer choices and may sometimes exaggerate benefits or omit important limitations. Clinical nutrition professionals use scientific evidence, label information, and ethical standards to judge whether a claim is accurate, relevant, and understandable. This protects people from misinformation and supports informed decisions; therefore, option C is correct.
