Diet therapy

Correct answer: C. When the patient has a serious kidney or liver problem

Explanation: Kidney or liver disease can alter the metabolism, storage, and removal of nutrients. An apparently harmless supplement may therefore cause toxicity or worsen electrolyte, fluid, protein, vitamin, or mineral imbalance. Selection and dosage should be based on clinical assessment, laboratory results, prescribed requirements, and professional supervision rather than routine use.

Correct answer: B. Consider portion and natural sugar

Explanation: People with diabetes usually do not need to eliminate all fruit. The important principles are choosing suitable whole fruits, controlling the portion and counting their carbohydrate contribution within the meal plan. Whole fruit generally provides fibre and is absorbed more slowly than juice, while unrestricted portions or sweet drinks can raise blood glucose rapidly. Therefore, option B is correct.

Correct answer: A. To identify hidden sodium

Explanation: Packaged foods may contain substantial sodium even when they do not taste extremely salty. Reading the nutrition panel and ingredient list helps a patient identify sodium, salt, monosodium glutamate, brine and other sodium-containing ingredients. Limiting these products supports a lower-sodium dietary pattern, which can assist blood-pressure control along with prescribed treatment. Hence, option A is correct.

Correct answer: B. Low-fat modification

Explanation: A puri is generally deep-fried and absorbs a considerable amount of oil, whereas a phulka is prepared on a griddle with little or no added fat. Replacing the fried item with phulka therefore lowers the fat content and may reduce saturated-fat intake in the overall meal. This is a change in food choice and cooking method within diet therapy, so option B is correct.

Correct answer: C. Because disease stage and reports vary

Explanation: Renal dietary prescriptions depend on kidney function, disease stage, urine output, dialysis status, fluid balance and laboratory findings. Potassium or sodium may need restriction in one patient, while protein requirements can differ before and during dialysis. A single rule cannot safely be applied to everyone. Therefore, changing disease status and reports make option C correct.

Correct answer: D. They may increase intestinal discomfort

Explanation: Very sugary drinks have a high osmotic load. Excess sugar may draw water into the intestine or be poorly absorbed, which can worsen loose stools, bloating and abdominal discomfort. They also do not provide the balanced sodium-and-glucose composition needed for effective oral rehydration. Proper oral rehydration solution is preferred when appropriate, so option D is correct.

Correct answer: A. Fibre absorbs water and helps make stool softer and bulkier

Explanation: Dietary fibre, particularly bulky fibre, retains water and increases stool volume while helping the stool remain soft. If fluid intake is inadequate, added fibre may leave the stool dry, hard or difficult to pass, and in some cases may worsen discomfort or blockage. Adequate fluids, gradual fibre increase and suitable activity are usually considered together. Thus, option A is correct.

Correct answer: A. Because it may be hard to digest

Explanation: Fever can increase metabolic demand, but illness may also reduce appetite and digestive tolerance. Heavy fried foods contain much fat, remain in the stomach longer and may cause nausea, fullness or indigestion. Energy can instead be supplied through small, frequent, nutrient-dense and easily digestible foods, with fluids as needed. Therefore, option A is correct.

Correct answer: A. It may interfere with iron absorption

Explanation: Tea contains polyphenols and tannin-like compounds that can bind non-haem iron in the meal and reduce its absorption in the intestine. Separating tea from iron-rich meals can therefore help improve iron utilization, although the complete management of anaemia depends on its cause and medical advice. Vitamin C-rich foods can enhance non-haem iron absorption. Hence, option A is correct.

Correct answer: B. Gluten-free alternative

Explanation: Celiac disease is an immune-mediated condition in which gluten damages the lining of the small intestine. Wheat contains gluten, while plain rice is naturally gluten-free, so rice can replace wheat as part of a carefully planned diet. However, sauces, packaged foods and cross-contamination must also be checked. Thus, option B correctly identifies the principle.

Correct answer: A. Because dietary management can differ

Explanation: Lactose intolerance usually results from insufficient lactase and causes digestive symptoms after lactose consumption, while milk allergy involves an immune response to milk proteins and may cause skin, respiratory or serious systemic reactions. Their severity, substitutes and emergency precautions differ. Correct identification prevents unnecessary restriction or dangerous exposure, so option A is correct.

Correct answer: C. Boiling or steaming

Explanation: Boiling and steaming generally require little or no added fat, so they help reduce the saturated fat and total fat contributed by cooking. Deep frying, excess ghee and cream can substantially increase energy and saturated-fat intake. The rest of the meal still matters, including fibre-rich foods and appropriate portions, but among these choices boiling or steaming is the better method. Thus, option C is correct.

Correct answer: A. In energy deficit, protein may be used for energy

Explanation: Severe burns create a hypermetabolic and catabolic state in which the body needs adequate energy as well as protein for tissue repair, immune function and recovery. If energy intake is too low, amino acids supplied for healing may be oxidized as fuel instead of being used to build new tissue. A professionally planned diet must therefore meet both energy and protein needs. Option A is correct.

Correct answer: A. To support the wound-healing process

Explanation: Pressure injuries increase the need for complete nutrition. Protein and energy support tissue formation, while vitamins and minerals such as vitamin C, vitamin A, zinc and iron contribute to collagen formation, immune function, oxygen transport and repair. Deficiencies can delay healing, although supplementation should be based on assessment rather than given indiscriminately. Therefore, option A is correct.

Correct answer: A. Fat digestion and tolerance may be affected

Explanation: Some liver and biliary conditions can impair bile production, bile flow or fat handling, leading to poor tolerance, nausea, bloating or steatorrhoea after high-fat meals. A temporary or individualized reduction in fat may therefore improve symptoms, but the exact prescription depends on the diagnosis, nutritional status and medical advice. Fat is still an important nutrient, so complete elimination is not implied. Option A is correct.

Correct answer: A. It can cause nutrient deficiency and adherence issues

Explanation: An extreme crash diet may provide too little protein, vitamins, minerals, fibre and energy, causing fatigue, loss of lean tissue and other health problems. It is often difficult to sustain, so weight may return when normal eating resumes. Evidence-based obesity management generally uses a nutritionally adequate, gradual and sustainable calorie deficit with activity and behavioural support. Therefore, option A is correct.

Correct answer: B. Choose tolerable flavours and small meals

Explanation: Cancer treatment may cause metallic taste, reduced taste, nausea, mouth soreness or early fullness. The diet should be individualized by trying tolerated flavours, suitable temperatures and textures, while offering small frequent meals to protect energy and protein intake. Strong spices or excess salt can worsen symptoms for some patients and are not universally appropriate. Thus, option B is correct.

Correct answer: B. Iron- and vitamin C-rich diet

Explanation: Low haemoglobin may indicate anaemia, although the exact cause must be investigated. A suitable plan may emphasize iron-rich foods such as legumes, green leafy vegetables, fortified cereals or animal sources, together with vitamin C, which improves absorption of non-haem iron. Tea or coffee close to meals may reduce absorption. The final treatment depends on medical evaluation, so option B is the appropriate primary focus.

Correct answer: A. Each patient’s condition, needs, and tolerance differ

Explanation: A disease label does not describe the whole patient. Diet planning must consider age, nutritional status, symptoms, disease severity, laboratory findings, treatment, allergies, swallowing ability, cultural preferences, food access, and tolerance. Two people with the same diagnosis may therefore need different amounts, textures, nutrients, or meal schedules. Individual assessment makes therapy safer and more effective.

Correct answer: A. Gradual monitored change according to the patient’s condition

Explanation: A therapeutic diet should be introduced gradually and adjusted to the patient’s diagnosis, nutritional status, appetite, digestive tolerance, and medical treatment. Monitoring symptoms, intake, weight, hydration, and relevant investigations helps identify intolerance early and prevents sudden nutritional stress. Therefore, a supervised, patient-specific transition is safer than abruptly stopping food or adding nutrients without assessment.

Correct answer: A. Identify practical barriers and modify the plan

Explanation: Understanding information does not guarantee adherence. The dietitian should explore barriers such as cost, cooking facilities, work schedule, family support, taste preferences, side effects, or confusing instructions. The plan can then be simplified and adapted through collaborative counselling. Identifying barriers and modifying the plan is more effective and respectful than blame or extreme restrictions.

Correct answer: A. Review symptom improvement, adherence, and related tests

Explanation: Diet-therapy outcomes should be evaluated using several relevant indicators rather than one superficial observation. Improvement in symptoms, actual adherence, body weight or functional status, dietary intake, and disease-specific laboratory results together show whether the intervention is effective. Follow-up also allows the diet plan to be adjusted safely when goals are not being achieved.

Correct answer: A. Meeting nutrition needs with regular safe adherence by the patient

Explanation: A therapeutic diet is successful when it fulfils the patient’s nutrient and energy requirements, is safe for the medical condition, and can be followed regularly. Adherence is essential because even a scientifically correct diet cannot help if the patient cannot accept or maintain it. Therefore, adequate nutrition combined with safe, consistent practice is the broadest indicator of success.

Correct answer: A. Assessment, an individualized plan, adherence, and monitoring

Explanation: Scientific diet therapy follows a systematic cycle. The patient is first assessed for diagnosis, nutritional status, symptoms, laboratory findings, lifestyle, preferences, and resources. A suitable individualized plan is then prepared, implemented, and reviewed for adherence and response. It is modified when necessary. This patient-centred assessment-to-monitoring process makes option A the correct answer.

Correct answer: B. Blood-glucose control and controlled energy intake

Explanation: A patient with both diabetes and obesity needs a plan that manages blood glucose while also supporting gradual, safe energy control. Appropriate portions, regular meal timing, high-fibre foods when suitable, better fat quality, and individualized carbohydrate distribution are generally more useful than total fasting or eliminating all carbohydrates. Therefore, option B gives the most balanced goal.
