Diet therapy

Correct answer: B. Strained fruit juice

Explanation: A low-fibre diet limits coarse fibre, seeds, peels, bran, and foods that may increase stool bulk or intestinal irritation. Strained fruit juice usually contains less fibre than whole fruit or juice with pulp, so it may be suitable in selected situations. The prescription and medical condition must guide its use.

Correct answer: C. Calcium and vitamin D

Explanation: Calcium is a major mineral in bone structure, while vitamin D helps the intestine absorb calcium and supports bone mineralisation. Adequate dietary sources, suitable sunlight exposure, physical activity, and treatment of underlying problems may be considered. Supplements should be used only when clinically indicated and advised.

Correct answer: D. Excess chilli and strong spices

Explanation: A bland diet is designed to reduce irritation and make digestion easier, especially when the gastrointestinal tract is sensitive. Strong chilli, very hot spices, and heavily fried or highly seasoned foods may aggravate symptoms in some patients. Foods should remain mild, soft, adequately cooked, and individually tolerated.

Correct answer: A. To choose alternatives within the same nutrition group

Explanation: A food-exchange list groups foods with approximately similar amounts of energy and important nutrients. It lets a patient replace one food with another from the same group while keeping the prescribed meal plan reasonably consistent. This improves variety, cultural suitability, choice, and long-term adherence to diet therapy.

Correct answer: B. Maintaining hygiene and preventing infection

Explanation: Covering hospital food protects it from dust, insects, droplets, handling, and microorganisms during preparation, transport, and service. This helps preserve food hygiene and reduces the possibility of food-borne infection, which is particularly important for patients whose immunity may be reduced. Safe temperature and clean utensils are also necessary.

Correct answer: C. Helping iron absorption

Explanation: Vitamin C improves the absorption of non-haem iron found in plant foods by helping keep iron in a more absorbable form. Amla, guava, citrus fruits, tomato, and lemon are useful sources. Tea or coffee taken with an iron-rich meal may reduce absorption, so meal timing and the total diet also matter.

Correct answer: D. Reducing saturated fat and using unsaturated fat in moderation

Explanation: Reducing saturated fat from foods such as excess butter, ghee, fatty meat, and some processed foods can help improve the blood-lipid profile. Replacing part of it with unsaturated fats from nuts, seeds, fish, or suitable vegetable oils may be beneficial when portions remain controlled. Fibre-rich foods and overall energy balance are also important.

Correct answer: A. To understand how quickly a food raises blood glucose

Explanation: The glycaemic index compares how quickly a carbohydrate-containing food raises blood glucose relative to a reference food. It can help with food selection, but it is not the only factor: portion size, total carbohydrate, cooking, ripeness, fibre, and the complete meal also affect glucose response. Individual advice remains important.

Correct answer: B. To know nutritional status and the effect of the diet

Explanation: Regular weight measurement helps identify trends in nutritional status, fluid balance, recovery, unintended loss, or excessive gain. When interpreted with intake, symptoms, laboratory results, and the clinical condition, it shows whether the diet is effective and whether the plan needs adjustment. A single measurement is less informative than a reliable trend.

Correct answer: C. When there is a risk of micronutrient deficiency

Explanation: Food fortification means adding selected vitamins or minerals to a commonly eaten food. It may help when a patient or population is at risk of deficiencies such as iron, iodine, vitamin A, or vitamin D deficiency, provided the product suits the clinical condition. It complements, but does not automatically replace, a balanced diet or prescribed treatment.

Correct answer: A. They can be part of heart-friendly fats

Explanation: Omega-3 fatty acids, especially those obtained from suitable fish, nuts, seeds, or medically advised sources, can be part of a heart-healthy eating pattern. Their benefit depends on the whole diet, amount, food source, and medical condition. They do not cure all diseases, and excessive supplements or oils may add unnecessary energy or interact with treatment.

Correct answer: B. To reduce gas and bloating

Explanation: A sudden large increase in fibre can cause gas, abdominal discomfort, bloating, cramps, or changes in bowel habits because the digestive system and intestinal bacteria need time to adapt. Increasing fibre step by step, choosing varied sources, and drinking adequate fluid when medically permitted can improve tolerance and support regular bowel movement.

Correct answer: A. To balance effects of some medicines and food

Explanation: Food can change how quickly a medicine is absorbed, how strongly it acts and whether it causes stomach irritation. Some medicines must be taken with food, whereas others work best before or between meals. Coordinating the schedule helps maintain treatment effectiveness and reduces avoidable adverse effects. Diabetes medicines are a common example, so option A is correct.

Correct answer: B. When the patient's condition or test results change

Explanation: A therapeutic diet is individualized and should be reviewed during follow-up. Changes in symptoms, weight, appetite, diagnosis, medication, laboratory values or treatment stage may alter nutrient requirements and restrictions. Regular monitoring prevents an unsuitable plan from continuing and allows the dietitian or doctor to adjust it safely. Thus, option B is the only appropriate answer.

Correct answer: C. Use lemon and mild herbs

Explanation: A low-sodium diet limits added salt and foods containing large amounts of sodium, such as pickles and many packaged sauces. Lemon juice, fresh herbs, mild spices, garlic, ginger, or other permitted flavourings can improve palatability without substantially increasing sodium. The exact diet should still follow the healthcare provider’s advice.

Correct answer: A. A patient with weak immunity

Explanation: Patients with weakened immunity have reduced ability to resist harmful microorganisms and may develop serious illness from contamination that would be mild in a healthy person. Their food requires careful hand hygiene, safe water, thorough cooking, prevention of cross-contamination, correct storage, and avoidance of unsafe raw or spoiled foods. This is an essential part of therapeutic care.

Correct answer: A. It may help reduce some potassium

Explanation: Some potassium can move from vegetables into the cooking water during soaking and boiling. Discarding that water may reduce the potassium content of the portion, although the amount removed varies with the vegetable, cutting size, water volume, and method. This practice should follow renal diet advice.

Correct answer: A. Assess intake and improve energy protein plan

Explanation: Rapid unintentional weight loss with reduced intake signals possible nutrition risk. The dietitian should assess dietary intake, symptoms, swallowing, disease status, medicines, and anthropometric changes, then modify the plan to provide suitable energy and protein. Progress should be monitored and urgent clinical causes referred appropriately.

Correct answer: A. Adherence and motivation improve

Explanation: Shared goal-setting respects the patient’s preferences, culture, routine, resources, and readiness to change. Goals that the patient helps choose are usually realistic and more meaningful, which increases motivation and adherence. The dietitian can then review progress and adjust the plan rather than imposing an impractical prescription.

Correct answer: B. Local options like pulses and milk

Explanation: A therapeutic diet must be nutritionally appropriate and affordable enough to follow. Pulses, beans, soy, milk or curd, eggs where acceptable, and other locally available foods can provide protein at lower cost than imported products. The final choice should also consider allergies, medical restrictions, culture, availability, and preparation facilities.

Correct answer: A. To avoid nutrient deficiency

Explanation: The confirmed allergenic food must be avoided to prevent an allergic reaction, but removing it without planning may reduce energy, protein, vitamins, minerals, or fibre. A safe substitute from a nutritionally comparable food group helps maintain adequate growth and health. Alternatives must be selected carefully to avoid the allergen and prevent cross-contact, preferably with professional guidance.

Correct answer: B. To help satiety and blood sugar control

Explanation: Dietary fibre, especially from vegetables, pulses, whole grains, and suitable fruits, can slow digestion and glucose absorption. This may reduce sharp post-meal blood glucose rises and improve fullness, which can support weight management. Fibre does not remove all carbohydrates, and portions and the total meal pattern still matter in diabetes.

Correct answer: A. Some substitutes may be high in potassium

Explanation: Many salt substitutes replace sodium chloride with potassium chloride. In kidney disease, impaired potassium excretion may cause potassium to accumulate in the blood, producing dangerous hyperkalaemia and heart rhythm problems. Therefore a salt substitute should not be assumed safe; kidney function, medicines, and laboratory results must be considered by a clinician.

Correct answer: A. Are you able to follow the plan

Explanation: Asking whether the patient can follow the plan reveals adherence, barriers, affordability, symptoms, preferences, and practical difficulties. The dietitian can use this information to modify portions, timing, recipes, or goals. Follow-up is not merely a formality; it connects the prescribed plan with the patient’s actual behaviour and response.

Correct answer: A. Deficiency of some nutrients and boredom

Explanation: A monotonous diet may exclude entire food groups and therefore reduce the supply of particular vitamins, minerals, protein sources, or fibre. Repetition can also cause boredom and reduce appetite and adherence. Appropriate variety, within medical restrictions, improves nutrient adequacy, enjoyment, and the likelihood that the patient will continue the therapeutic plan.
