Diet therapy

Correct answer: B. Patient's condition and nutritional need

Explanation: Diet planning during illness is part of diet therapy and must be individualized. The planner considers the disease, severity, symptoms, digestion and absorption, treatment, allergies, food tolerance, age and nutritional requirements. A suitable diet supports recovery while avoiding foods that may worsen the condition; therefore, option B is correct.

Correct answer: A. Nutrition care in disease management

Explanation: A therapeutic diet is a planned modification of normal food intake used to support the treatment or management of a disease or medical condition. It may alter nutrients, energy, texture, consistency, meal timing or feeding method according to the patient’s diagnosis and tolerance. It works alongside medical care and should be planned by an appropriately qualified professional. Thus, option A is correct.

Correct answer: A. To make the diet affordable and acceptable

Explanation: Using locally available foods can make a planned diet more affordable, culturally familiar, seasonal, practical, and acceptable to the person or family. Familiar foods are usually easier to purchase, prepare, and include regularly, which improves adherence to dietary advice. Local availability does not automatically reduce nutritional quality; foods should still be selected hygienically and combined to meet energy and nutrient needs. Therefore, option A is correct.

Correct answer: B. To improve diet acceptance and adherence

Explanation: Religious and cultural food habits influence what a patient is willing and able to eat. When a therapeutic diet respects acceptable foods, preparation methods, and customary practices, the patient is more likely to accept the meals, consume the required nutrients, and follow the diet consistently. This improves dietary adherence and supports recovery; it does not alter laboratory reports or the colour of medicines. Therefore, option B is correct.

Correct answer: D. In some diseases, on a doctor’s or dietitian’s advice

Explanation: Salt intake may need to be limited in selected medical conditions, such as hypertension, certain heart problems, kidney disease, or fluid retention. The degree of restriction depends on the patient’s diagnosis and treatment plan, so it should not be imposed casually. Option D is correct because professional advice is required.

Correct answer: A. It can help the patient accept the diet better

Explanation: Knowing a patient’s food preferences helps the nutrition professional select acceptable foods and design a more realistic meal plan. When the diet respects taste, culture, habits, and available foods, the patient may be more willing to eat it and follow the advice. Preference improves acceptability, but it does not cure disease by itself.

Correct answer: B. To help decide food quantity

Explanation: Appetite gives useful information about how much and how often a patient is likely to eat. A person with poor appetite may need small portions, attractive presentation, appropriate meal spacing and nutrient-dense foods, while the plan must still meet medical and nutritional requirements. Appetite alone does not replace professional assessment, but it helps adjust the practical amount and frequency of food. Hence, option B is correct.

Correct answer: B. When light and easily digestible food is needed

Explanation: Reducing strong spices can be useful when a patient needs a mild, light or easily digestible diet, or when spicy foods worsen gastrointestinal discomfort. This modification may improve acceptance and tolerance, although the exact restriction depends on the person's symptoms and medical advice. It does not relate to painting, buying shoes or printing a book. Thus, the need for light and easily digestible food makes option B correct.

Correct answer: A. To improve acceptance and compliance

Explanation: Taste, aroma, appearance, and texture influence whether a patient is willing to eat the prescribed diet. If food is nutritious but unpleasant, the patient may leave it unfinished, skip meals, or fail to follow the diet consistently. Considering taste within medical and nutritional restrictions improves acceptance and compliance. Taste alone cannot cure disease, but it supports adequate intake and the success of diet therapy.

Correct answer: C. Because it may cause nutrient deficiency or harm

Explanation: A strict restriction can remove important calories, protein, vitamins, minerals or fluids from the diet if it is not medically justified. Patients have different diseases, treatments and nutritional needs, so a therapeutic diet must be planned and monitored by a qualified professional. Unsupervised restrictions may worsen weakness or delay recovery.

Correct answer: B. It can improve diet acceptance and adherence

Explanation: A therapeutic diet is useful only when the patient is willing and able to eat it. Pleasant, familiar, and appropriately prepared flavours can improve appetite, acceptance, and adherence, helping the patient consume the prescribed nutrients. Taste must still be balanced with medical restrictions, texture, safety, and the patient’s cultural preferences.

Correct answer: D. Providing adequate fluids

Explanation: Adequate fluid intake helps replace water lost through urine, sweat, breathing, vomiting, diarrhoea, or fever and therefore supports normal hydration. Fluid needs vary with age, illness, weather, activity, and kidney or heart function. In clinical care, the prescribed amount and the patient’s ability to drink must be considered rather than giving an identical volume to everyone.

Correct answer: A. Low-salt homemade food

Explanation: A low-sodium diet limits added salt and foods that contain large amounts of sodium. Low-salt homemade food is usually a better choice because ingredients and seasoning can be controlled. Packaged snacks, pickles, papad, sauces, and processed foods may contain hidden sodium, so labels and portion sizes should also be checked. The exact restriction depends on medical advice.

Correct answer: C. Energy- and protein-rich foods

Explanation: An underweight patient may benefit from energy-dense and protein-rich foods, provided that the cause of low weight and the patient’s medical condition are assessed. Nutrient-dense meals, nourishing snacks, and appropriate fortification can increase intake without relying only on large meal volumes. The plan should also consider appetite, digestion, allergies, infection, and any underlying disease.

Correct answer: D. To help protect the patient from infection

Explanation: Hygienic food service includes safe hand hygiene, clean equipment, safe water, proper cooking, protection from contamination, correct storage temperatures, and careful serving. Patients may have weakened immunity, so contaminated food can cause serious food-borne infection and delay recovery. The purpose is not to make food costly or less nutritious; it is to protect patient safety, making option D correct.

Correct answer: A. Advice from a health professional

Explanation: Dietary restrictions should be prescribed or approved by an appropriate health professional, such as a doctor or registered dietitian, after considering the patient’s disease, nutritional status, medicines, allergies, and food needs. Unplanned restrictions may cause nutrient deficiencies or interfere with treatment. Therefore, option A is correct because expert advice protects both safety and nutritional adequacy.

Correct answer: C. Helping control blood sugar

Explanation: A diabetes diet plan aims to distribute carbohydrate-containing foods appropriately, support regular meal timing, provide adequate nutrients, and help keep blood glucose within the individually recommended range. It does not mean permanently stopping food; people with diabetes still need balanced meals and suitable portions. Diet is one part of management and works together with prescribed medicines, physical activity, monitoring, and medical advice. Therefore, helping control blood sugar is the relevant general aim.

Correct answer: D. To help manage blood pressure

Explanation: Excessive sodium intake can promote water retention and may increase the amount of fluid in the circulation in salt-sensitive individuals. This can contribute to elevated blood pressure. Consequently, reducing very salty foods and avoiding unnecessary added salt may support blood-pressure management, especially when recommended by a qualified healthcare professional. Salt control is not a complete treatment by itself; it should accompany an overall plan that may include medicines, physical activity, weight management, and monitoring. Thus, option D is correct.

Correct answer: B. For suitability according to the disease

Explanation: A therapeutic diet is modified to meet the nutritional needs and limitations created by a disease or medical treatment. The type of food may be changed to control nutrients, avoid harmful ingredients, manage allergies, improve tolerance, or support healing. For example, a patient may require low-sodium, diabetic, soft, or renal-friendly choices. Thus, option B is correct.

Correct answer: C. A plan containing only costly and unavailable foods

Explanation: A practical diet plan must be realistic for the patient’s household. It should use foods that are available, affordable, culturally acceptable and possible to prepare, while still meeting medical and nutritional needs. A plan based only on costly or unavailable foods cannot be followed consistently, even if it appears nutritionally ideal on paper. Therefore, option C correctly identifies an impractical plan.

Correct answer: B. It makes food suitable according to the disease and treatment needs

Explanation: A therapeutic diet is planned or modified to support a particular disease, symptom, treatment, or stage of recovery. Changes may involve energy, protein, carbohydrate, fat, sodium, fluid, fibre, meal frequency, or food texture. Such a diet complements medical care, helps control symptoms and complications, and supports healing, but it should follow professional advice. Hence, option B is correct.

Correct answer: C. Helping control blood glucose

Explanation: In diabetes, planning the amount, timing, and type of carbohydrate-containing foods can help reduce sharp changes in blood glucose. A suitable plan also considers energy needs, fibre, meal distribution, medication, activity, and individual health conditions. Diet cannot replace prescribed treatment, but it is an important part of diabetes management. Therefore, option C is correct.

Correct answer: A. When the patient has a low appetite

Explanation: Small and frequent meals are useful when a patient has poor appetite or cannot tolerate a large meal. Dividing the daily requirement into manageable portions can improve intake and reduce discomfort. The exact plan must still consider the illness, swallowing ability, digestive tolerance, and medical advice, rather than applying the approach automatically to every patient.

Correct answer: A. To ensure patient safety by avoiding foods that trigger an allergic reaction

Explanation: Knowing a patient’s food allergy is a patient-safety requirement because even a small amount of an allergen may cause itching, swelling, vomiting, breathing difficulty, or a life-threatening reaction such as anaphylaxis. Allergy information guides safe menu planning and prevents accidental exposure. Calorie calculation is a separate assessment, so option A is correct.

Correct answer: C. It modifies food according to the disease condition

Explanation: A therapeutic diet is a planned modification of the usual diet to meet the needs created by a disease or medical condition. Changes may involve energy, protein, fat, sodium, sugar, fibre, fluid, meal timing, or food consistency. The purpose is to support treatment, control symptoms, prevent complications, and promote recovery. It is not identical for every patient. Thus, option C is correct.
