Diet therapy

Correct answer: A. An energy- and protein-rich diet

Explanation: Protein-energy malnutrition involves inadequate energy, protein, or both, so rehabilitation commonly requires energy-dense and protein-rich foods. These support weight gain, growth, tissue repair, enzymes, hormones, and immunity. Feeding should be gradual and monitored in severe cases because sudden feeding may create metabolic complications.

Correct answer: A. Nutritional balance according to the disease

Explanation: A patient’s diet should be acceptable in taste but also nutritionally adequate and appropriate for the disease. It may need modified energy, protein, sodium, fat, fibre, fluid, texture, or meal frequency. Palatability improves intake, while scientific planning ensures that the diet supports treatment and avoids worsening the condition.

Correct answer: A. The disease stage and medical advice

Explanation: Renal diet planning varies with kidney function, disease stage, dialysis status, urine output, laboratory values, blood pressure, and coexisting conditions. Depending on the case, protein, sodium, potassium, phosphorus, fluids, or energy may need adjustment. Because requirements differ greatly, the plan must be individualised by qualified professionals.

Correct answer: A. To provide nutrition according to the illness

Explanation: Diet therapy means planning and providing food according to a person’s disease, symptoms, nutritional requirements and treatment goals. It may adjust energy, protein, fat, carbohydrates, sodium, fluids, fibre, texture or meal timing. It supports recovery and disease management, but it does not automatically replace prescribed medicines. Therefore, option A is correct.

Correct answer: B. Controlled distribution of carbohydrates

Explanation: Carbohydrate amount, type and distribution across meals strongly influence post-meal blood glucose. A diabetic meal plan generally emphasises regular meals, high-fibre choices, suitable portions and limiting added sugars, while being individualised to medicines, activity and health status. Skipping meals or relying on juice is unsafe. Hence, controlled carbohydrate distribution in option B is correct.

Correct answer: C. Sodium

Explanation: Reducing sodium is a common dietary measure for hypertension because excess sodium can promote water retention and increase the volume of fluid in the circulation, raising blood pressure in susceptible people. The plan should also emphasise fresh foods and limit added salt, pickles, papad and highly processed foods. Therefore, option C is correct, although individual advice may vary.

Correct answer: D. Difficulty in chewing or swallowing

Explanation: A soft diet contains foods that are tender, moist and easy to chew and swallow. It can be useful for people with dental problems, swallowing difficulty, weakness, or during selected stages of recovery after surgery. It should still provide adequate energy and nutrients and must be adapted to the patient’s swallowing safety. Thus, option D is correct.

Correct answer: A. Gallbladder and heart-related problems

Explanation: A low-fat diet may be advised in gallbladder disorders to reduce the digestive workload and discomfort associated with fat, and in many cardiovascular conditions to help reduce saturated and trans-fat intake. The exact prescription depends on diagnosis and medical advice. It does not specifically treat a common cold, low blood pressure or calcium deficiency. Hence, option A is correct.

Correct answer: B. A burn or wound-healing patient

Explanation: Protein supplies amino acids needed for new tissue formation, immune function and wound repair. Requirements may rise after burns, injury or surgery, so a high-protein plan can be useful when clinically prescribed. Severe kidney disease may require protein adjustment rather than unsupervised increase, and protein alone does not correct dehydration. Therefore, option B is correct.

Correct answer: C. Protein and electrolyte control

Explanation: Kidney disease can impair the body’s ability to excrete nitrogenous waste, sodium, potassium, phosphorus and excess fluid. Depending on the stage of disease, dialysis status and laboratory findings, the dietitian may modify protein, electrolytes, fluids and energy. These changes must be individualised rather than applied identically to every patient. Thus, option C is correct.

Correct answer: D. Being mildly spiced and easy to digest

Explanation: A bland diet is designed to be gentle on the digestive tract. It generally uses mild seasoning, soft or easily digested foods and limited irritants such as very hot spices, excessive frying and sometimes acidic items, depending on tolerance. It is not necessarily nutritionally inadequate and should be planned to meet the patient’s needs. Therefore, option D is correct.

Correct answer: A. Increasing fibre and water

Explanation: Dietary fibre adds bulk and can help stimulate normal bowel movement, while adequate water helps hydrate and soften the stool. Whole grains, pulses, vegetables and fruits are useful sources, and gradual fibre increase may improve tolerance. Physical activity and medical evaluation may also be needed. Thus, option A is the appropriate general principle, unless a clinician advises otherwise.

Correct answer: B. Replacing water and electrolytes

Explanation: Diarrhoea causes loss of water and electrolytes such as sodium and potassium, which can rapidly lead to dehydration. Initial care therefore prioritises oral rehydration solution or other clinically appropriate fluids, continued suitable nutrition and monitoring for danger signs. Severe dehydration, blood in stool or persistent symptoms require medical care. Hence, option B is correct.

Correct answer: A. Gluten-free diet

Explanation: Celiac disease is an immune-mediated condition in which gluten triggers intestinal injury. A strict gluten-free diet avoids wheat, barley, rye and foods contaminated with them, allowing the intestinal lining to heal and improving nutrient absorption. Oats may require special consideration because of contamination and individual advice. Therefore, option A is correct, and the diet should be professionally planned for nutritional adequacy.

Correct answer: C. Providing adequate fluids and energy

Explanation: Fever can increase fluid loss through sweating and may raise energy needs because of a higher metabolic rate. Diet planning therefore commonly emphasises adequate fluids, easily digested energy-giving foods and small frequent meals according to appetite and tolerance. Food should not be stopped without a medical reason, and fluid restriction is inappropriate unless specifically prescribed. Hence, option C is correct.

Correct answer: D. Iron- and vitamin C-rich foods

Explanation: Iron is needed to make haemoglobin, while vitamin C improves the absorption of non-haem iron from plant foods. Helpful choices may include pulses, green leafy vegetables, fortified foods, meat when appropriate and amla or citrus fruits. Excess tea with meals can reduce iron absorption because of polyphenols. The cause of anaemia still requires diagnosis, but option D is the best dietary combination.

Correct answer: A. Balanced energy control and regular meals

Explanation: A safe obesity-management plan creates a sustainable, individually appropriate reduction in energy intake while preserving protein, fibre, vitamins and minerals. Regular meals, portion awareness, minimally processed foods and physical activity are generally more useful than starvation or crash diets. The goal is gradual improvement in health and body weight, not severe restriction. Therefore, option A is correct.

Correct answer: B. Energy- and protein-dense foods

Explanation: An underweight person may need energy-dense and protein-rich foods to support healthy weight gain, muscle maintenance and tissue repair. Examples can include pulses, dairy or suitable alternatives, eggs, nuts, seeds, healthy oils and fortified snacks, provided they fit the person’s condition. Small frequent meals can improve intake. The cause of low weight should also be assessed, so option B is correct.

Correct answer: C. Very spicy and acidic food

Explanation: Very spicy or acidic foods may aggravate burning, pain or digestive discomfort in some people with peptic ulcer disease. A gentle diet with less irritating preparation may improve tolerance, but food triggers differ between individuals and diet does not replace medical treatment for the ulcer. Avoiding only foods that cause symptoms is preferable to unnecessary broad restriction. Therefore, option C is the best answer.

Correct answer: A. It improves patient compliance with the diet

Explanation: Considering cultural, religious, sensory and personal food preferences makes a therapeutic plan more acceptable and realistic. When patients like and understand the foods included, they are more likely to follow portions, meal timing and restrictions consistently. Preferences must still be balanced with nutritional needs, allergies, safety and medical goals; they do not cure disease or automatically replace medicine. Hence, option A is correct.

Correct answer: A. Changing food according to disease and need

Explanation: Diet modification means deliberately changing the type, amount, texture, nutrient content, consistency, timing or preparation of food to meet a patient’s medical and nutritional needs. Examples include reducing sodium, controlling carbohydrates, increasing fibre, altering protein or changing from solid to soft foods. It is not the same as eliminating all food or mixing medicines into meals. Therefore, option A is correct.

Correct answer: C. To prevent infection

Explanation: Hygiene is essential in diet therapy because a sick person may have reduced immunity and may be more vulnerable to food-borne infection. Clean hands, utensils, water, preparation surfaces, and proper storage help prevent contamination. Therefore, the correct answer is C, prevention of infection; taste, colour, and calories are not the main purpose of hygiene.

Correct answer: D. Reducing weight loss and weakness

Explanation: A general nutritional goal in cancer care is to maintain body weight, energy, muscle tissue, hydration, and treatment tolerance. Appetite may be poor, while energy and protein needs can increase. Small, frequent, nutrient-dense meals may help. Hence D is correct; stopping food, providing only empty calories, or removing all protein would worsen nutritional status.

Correct answer: A. Giving strained soup

Explanation: Straining soup removes coarse particles and produces a smoother consistency, which may make it easier for a patient with swallowing or digestive difficulty to consume. Texture modification includes liquid, semi-liquid, soft, minced, or pureed forms. Salt, colour, or the name of a food does not change its physical texture, so A is correct.

Correct answer: B. Low-fat food

Explanation: A low-fat diet may be recommended in some gallbladder conditions because fat stimulates gallbladder contraction and digestion requires bile. Reducing fried foods, cream, butter, and other greasy items can lessen digestive discomfort for some patients. The exact restriction depends on the diagnosis and medical advice, but B is the appropriate general choice.
