Clinical nutrition

Correct answer: D. Bones, blood, and body functions

Explanation: Minerals are inorganic nutrients that perform structural and regulatory functions in the body. Calcium and phosphorus help build and maintain bones and teeth; iron is needed for haemoglobin and oxygen transport; sodium and potassium help maintain fluid balance and nerve and muscle activity; and iodine supports thyroid hormone production. Thus minerals contribute to bones, blood, and normal body functions. They do not primarily affect plate shine, food smell, or cooking time.

Correct answer: A. It maintains fluid balance in the body

Explanation: Water is essential for maintaining blood volume and fluid balance, transporting nutrients, removing waste through urine, regulating body temperature, lubricating joints, and supporting digestion and cellular reactions. Illness, fever, vomiting, diarrhoea, sweating, or some treatments can increase fluid loss, while certain heart or kidney conditions may require carefully prescribed limits. Therefore the patient’s water intake should be adequate and clinically appropriate, not treated merely as a matter of taste.

Correct answer: B. Deficiency or excess of nutrients

Explanation: Malnutrition is a condition in which the body receives, absorbs, or uses nutrients inadequately or excessively. It includes undernutrition, such as wasting, stunting, or micronutrient deficiencies, and overnutrition, such as overweight and obesity. The term therefore does not mean only hunger or insufficient food. Poor diet quality, disease, impaired absorption, increased requirements, and excessive intake can all contribute to malnutrition and may affect growth, immunity, healing, and health.

Correct answer: B. Balanced energy control

Explanation: Obesity management requires a sustainable balance in which energy intake is appropriate in relation to energy expenditure, while the diet still supplies protein, vitamins, minerals, fibre, and adequate fluids. Portion control, nutrient-dense foods, regular activity, sleep, and behaviour change are often combined. A suitable calorie reduction should be gradual and individualised rather than based on starvation or eliminating water. Increasing sweets or fried foods would generally increase excess energy intake.

Correct answer: C. Protein and energy

Explanation: During recovery, the body may need additional protein and energy to replace damaged tissue, support immune responses, produce enzymes and blood components, and restore strength. Protein supplies amino acids for healing, while energy from carbohydrates and fats helps spare protein for tissue building. The actual requirement depends on the illness, wound size, age, appetite, kidney function, and treatment, so it should be assessed and prescribed appropriately. Spices, colour, and packaging do not meet these needs.

Correct answer: D. Understanding the patient’s food habits

Explanation: A diet history records what a person usually eats and drinks, including the types and quantities of foods, meal timing, preparation methods, snacks, supplements, preferences, intolerances, and barriers to eating. It helps identify nutrient gaps, excesses, irregular patterns, allergies, and cultural or financial factors that may affect the diet. This information becomes an important part of nutritional assessment and allows a realistic care plan to be prepared.

Correct answer: C. Porridge

Explanation: Porridge is commonly suitable for a soft diet because cooking makes it tender, moist, and easy to chew and swallow. Its ingredients and thickness can be adjusted to the patient’s condition, and it may provide energy and other nutrients when prepared appropriately. Hard dry chickpeas and fried snacks are difficult to chew, while very spicy foods may irritate some patients. The exact food list should still follow the prescribed consistency and the patient’s tolerance.

Correct answer: D. Milk and soup

Explanation: A full liquid diet includes foods and drinks that are liquid or become liquid at room temperature and can usually be swallowed without chewing. Depending on the prescription, it may include milk, strained soup, yoghurt, custard, smooth porridge, nutritious beverages, and other suitable liquids. The diet must provide as much energy and protein as possible and may require fortification or supplements. Raw nuts, dry gram, and hard paratha are solid foods and do not fit a full liquid diet.

Correct answer: A. Hypertension

Explanation: A low-sodium diet is useful in hypertension because excess sodium can encourage water retention and may contribute to increased blood pressure. Reducing salt intake can support blood-pressure control, especially when combined with medical advice, appropriate medicines, physical activity, and other prescribed dietary changes. It should be followed according to the healthcare professional’s guidance.

Correct answer: C. To teach the patient how to follow the correct diet

Explanation: Patient education explains the purpose, food choices, portions, timing, and precautions of a prescribed diet. When the patient understands these instructions, adherence is more likely during hospital care and after discharge. Education also helps the patient identify practical ways to continue the plan at home.

Correct answer: B. Fibre and water

Explanation: Dietary fibre adds bulk and can help form softer, more manageable stools, while adequate fluid supports the movement of stool through the intestine. Fruits, vegetables, pulses, and whole grains are useful sources. Fibre should be increased gradually, and medical advice is important in special conditions.

Correct answer: C. Dehydration

Explanation: Diarrhoea causes repeated loss of water and electrolytes such as sodium and potassium. If these losses are not replaced, dehydration can lead to weakness, dizziness, reduced urination, shock, and serious complications. Oral rehydration solution and professional medical care are important, especially for children and older adults.

Correct answer: A. Clean and attractive serving

Explanation: Clean, appealing presentation can stimulate interest and make a patient more willing to eat. Suitable colour, aroma, temperature, portion size, and pleasant serving practices may improve acceptance, while hygiene must always be maintained. Personal preference and the prescribed therapeutic restrictions should also be respected.

Correct answer: B. Nutrition assessment

Explanation: Nutrition assessment is generally the first step because it collects information about dietary intake, anthropometry, biochemical data, clinical signs, medical history, and social factors. This information helps identify nutrition problems and provides a sound basis for diagnosis, intervention, monitoring, and follow-up.

Correct answer: C. Weight management

Explanation: A calorie-controlled diet adjusts energy intake to support a suitable body weight. When intake is lower than expenditure, gradual weight loss may occur; when intake matches expenditure, weight can be maintained. The plan must remain nutritionally balanced and should be individualized rather than based on extreme restriction.

Correct answer: D. Weight loss and weakness may occur

Explanation: Very low energy intake may prevent the body from meeting its needs for activity, metabolism, tissue repair, and temperature regulation. The person may lose weight and develop fatigue, weakness, poor concentration, or nutrient deficiencies. Persistent restriction can be harmful and should be assessed by a nutrition professional.

Correct answer: C. To improve diet compliance

Explanation: Considering reasonable food preferences makes a prescribed diet more acceptable and practical. A patient is more likely to eat meals that fit cultural habits, taste, budget, and usual routines, provided they meet therapeutic requirements. Better acceptance can improve adherence and nutritional intake without replacing professional dietary guidance.

Correct answer: A. Fruits and whole grains

Explanation: Fruits and whole grains are good sources of dietary fibre. Fibre supports bowel regularity, contributes to fullness, and can help maintain healthy blood glucose and cholesterol patterns when included in a balanced diet. Fibre-rich choices include vegetables, pulses, nuts, seeds, and intact or minimally refined grains.

Correct answer: D. Because some medicines can affect nutrition or food intake

Explanation: Some medicines can change appetite, taste, digestion, absorption, fluid balance, or the use of particular nutrients. Food can also alter the absorption or effect of certain medicines. Considering drug–diet interactions helps professionals plan safer meals and medication timing, while the patient should follow advice from the healthcare team.

Correct answer: A. In some heart and obesity-related conditions

Explanation: A low-fat diet may be useful for some people with cardiovascular risk or obesity as part of an overall balanced plan. Replacing excess saturated and trans fats with healthier choices can support heart health, while appropriate energy control can assist weight management. Advice must be individualized to the patient.

Correct answer: B. Because it can provide protein and calcium

Explanation: Milk can provide high-quality protein, calcium, phosphorus, and several other nutrients. Protein supports growth and tissue maintenance, while calcium contributes to bones and teeth. Its nutritional value varies among products, and people with lactose intolerance, allergy, or dietary restrictions may need suitable alternatives recommended by a professional.

Correct answer: C. It provides a record of daily food intake

Explanation: A food diary records what a person eats and drinks, including portions, timing, preparation, snacks, and sometimes symptoms. This information helps a dietitian identify intake patterns, missed nutrients, excesses, intolerances, and barriers to adherence. It therefore supports a more accurate nutrition assessment and counselling plan.

Correct answer: D. Because it may burn the mouth and cause discomfort

Explanation: Very hot food should not be served to a patient because it can burn the lips, mouth, tongue, throat, or digestive lining and may cause pain or difficulty in eating. Ill, weak, elderly, or sedated patients may be less able to judge temperature accurately. Food should therefore be checked and served at a safe, comfortable temperature.

Correct answer: A. To check the effect of the diet plan

Explanation: Follow-up evaluates whether the nutrition intervention is being followed and whether it is improving the patient’s symptoms, intake, weight, laboratory values, functional status, or other goals. The plan can then be continued, strengthened, or modified. Regular review is essential because medical and nutritional needs may change.

Correct answer: A. When digestion is weak or there is weakness due to illness

Explanation: Easily digestible food is useful when illness, fever, surgery or digestive weakness makes it difficult to process heavy meals. Soft, mild and properly cooked foods generally place less strain on the digestive system while supplying needed nutrients. The exact choice still depends on the disease and professional advice; it is not related to decoration or utensils.
