Diet therapy

Correct answer: B. A diet modified to help manage or treat a disease

Explanation: A therapeutic diet is a normal diet modified in amount, consistency, nutrients, or meal pattern to meet the needs of a person with a disease or medical condition. It supports treatment but must be planned according to professional advice. Thus, option B gives the correct meaning.

Correct answer: A. Keeping added sugar and carbohydrate intake controlled and distributed appropriately

Explanation: Diabetes diet planning aims to support blood-glucose control while providing adequate energy and nutrients. Carbohydrate quantity, quality and distribution across meals are considered, and added sugars are generally limited. A balanced plan may include fibre-rich foods and individualized portions; it does not require eating only fat, avoiding all vegetables or stopping water. Hence, option A is correct.

Correct answer: B. Reducing salt or sodium intake

Explanation: Reducing excessive sodium intake is a common dietary measure in hypertension. Sodium can contribute to fluid retention and may increase blood pressure in susceptible individuals. A suitable plan may also emphasize fruits, vegetables, whole grains and overall dietary balance, depending on medical advice. It does not require avoiding all fruit or eating sweets. Therefore, option B is correct.

Correct answer: D. For healing and digestive support

Explanation: After surgery, the body may require extra support for tissue repair, recovery, and restoration of strength. Digestion, appetite, and tolerance may also be temporarily affected. Therefore, the diet may be modified in amount, texture, frequency, or nutrient content to support healing and comfortable digestion under professional guidance.

Correct answer: A. The patient’s age, disease, and preferences

Explanation: An individualized diet is planned after considering factors such as age, sex, diagnosis, nutritional status, appetite, digestion, food tolerance, cultural practices, and personal preferences. These factors help make the diet safe, suitable, acceptable, and nutritionally adequate rather than applying exactly the same plan to every patient.

Correct answer: B. So that the patient can consume the diet safely and comfortably

Explanation: Tolerance means how well a patient can accept, digest, swallow, and comfortably consume a food or modified diet. Considering tolerance helps prevent nausea, pain, choking, intolerance, or refusal. It makes diet therapy safer, more acceptable, and more likely to provide the nutrients needed for recovery.

Correct answer: A. Modifying diet according to disease

Explanation: Therapeutic nutrition means adapting the patient’s diet to support management of a disease or medical condition. Changes may involve energy, protein, salt, sugar, fibre, fluids, meal frequency or food consistency, depending on professional assessment. It is part of treatment support and should be prescribed or supervised by qualified health professionals.

Correct answer: B. The patient’s disease and nutrition need

Explanation: Medical nutrition therapy is an individualized approach based on the patient’s diagnosis, symptoms, treatment, nutritional status and nutrient requirements. Personal preferences, culture and resources are also considered so that the plan is acceptable and practical, but the disease and nutrition needs provide its clinical foundation. It should be planned by a qualified professional.

Correct answer: D. To clarify the type and amount of diet

Explanation: A written diet prescription communicates the required type, texture, amount, timing and restrictions of food for a particular patient. It guides the kitchen, nursing staff, patient and family, and helps the healthcare team provide consistent care. The prescription is part of the treatment plan and should reflect the patient’s condition and professional advice.

Correct answer: B. Monitoring and evaluation

Explanation: Monitoring and evaluation determine whether a nutrition intervention is being implemented and whether it produces the intended outcomes. The professional may review food intake, weight, laboratory values, symptoms, tolerance, or other measurable indicators and compare them with the original goals. The plan can then be continued, modified, or stopped appropriately. Therefore, option B is correct.

Correct answer: C. Avoid the identified allergen food

Explanation: The main dietary rule in food allergy is strict avoidance of the specific food or ingredient that triggers the immune reaction. Labels, cross-contact during preparation, and hidden ingredients must also be considered. However, all foods should not be removed unnecessarily; safe alternatives should maintain adequate energy and nutrient intake under professional guidance.

Correct answer: C. When the patient has swallowing or digestive difficulty

Explanation: A high-fibre diet should not be increased suddenly in a patient who has difficulty swallowing, poor gastrointestinal tolerance, obstruction risk, or certain digestive problems. Fibre may need to be modified in form and amount, and adequate fluid may be necessary. The patient’s diagnosis and tolerance should guide the plan rather than applying the same diet to everyone.

Correct answer: B. A balanced reduced-energy diet with behaviour change

Explanation: Obesity is best managed through a sustainable reduction in energy intake, nutritious food choices, suitable physical activity, and gradual behaviour change. A balanced reduced-energy diet should provide essential nutrients and avoid extreme restriction. Crash diets and complete food avoidance can cause nutrient deficiencies, loss of muscle, fatigue, and later overeating. Individual goals should be planned with professional guidance.

Correct answer: B. Fibre, fluids, and physical activity

Explanation: Constipation is often helped by gradually increasing fibre from vegetables, fruits, whole grains, and pulses, together with adequate fluids and regular physical activity. Fibre should be increased according to tolerance, because a sudden increase without enough fluid may cause bloating or discomfort. Severe, sudden, painful, or persistent constipation needs medical evaluation to exclude an underlying condition.

Correct answer: D. To understand the patient’s problems and barriers

Explanation: Active listening means paying close attention to the patient, understanding both spoken and unspoken concerns, asking suitable questions, and responding empathetically. In diet counselling, it helps identify barriers such as cost, food preferences, cultural practices, poor appetite, or lack of family support. Understanding these barriers allows the counsellor to prepare a practical plan that the patient is more likely to accept and follow.

Correct answer: D. Helping the body repair and regain strength

Explanation: Convalescence is the period of recovery after illness, injury, or treatment. During this stage, an appropriate diet supplies enough energy, protein, vitamins, minerals, fluids, and other nutrients to support tissue repair, restore muscle and immune function, replace losses, and gradually rebuild strength. The exact diet should be adjusted to the patient’s condition and tolerance.

Correct answer: C. The patient’s disease or intolerance

Explanation: Food restrictions in a therapeutic diet should have a clear clinical reason, such as the patient’s disease, allergy, intolerance, swallowing problem, or prescribed nutrient restriction. Unnecessary elimination can reduce variety, enjoyment, and nutrient adequacy. The plan should therefore be individualized and professionally supervised. Option C is the correct answer.

Correct answer: A. Adjusting the diet according to the patient’s condition

Explanation: Diet adaptation means tailoring the type, quantity, texture, timing, or nutrient content of food to the patient’s disease, symptoms, treatment, tolerance, culture, and nutritional requirements. It is not a cosmetic or arbitrary change. Individualized adaptation makes the diet safer, more acceptable, nutritionally suitable, and more likely to support recovery and adherence.

Correct answer: C. So changes can be made according to the patient’s changing needs

Explanation: A patient’s symptoms, appetite, laboratory findings, treatment, food tolerance, and personal circumstances may change during care. A flexible plan allows safe substitutions and appropriate adjustments without abandoning therapeutic goals. It also respects preferences and improves adherence. Flexibility does not mean ignoring medical restrictions; every change must remain clinically safe and nutritionally adequate.

Correct answer: D. When the digestive tract needs rest

Explanation: A low-fibre diet may be prescribed temporarily when the digestive tract needs reduced stimulation or rest, such as during certain acute gastrointestinal conditions or after some procedures. Fibre normally adds bulk and promotes bowel movement, so reducing it can help control irritation, stool volume, or discomfort. It should be used only for the indicated period and under professional guidance, because long-term restriction may reduce fibre benefits.

Correct answer: D. So that the plan remains practical and sustainable

Explanation: A therapeutic diet should be nutritionally adequate as well as affordable and realistic for the patient’s household. Offering lower-cost equivalents, seasonal foods, locally available ingredients, and different preparation choices can preserve nutrient goals without creating financial hardship. A plan that fits the budget is more likely to be followed consistently, making it more sustainable and clinically useful over time.

Correct answer: A. The patient’s medical needs and balanced nutrition

Explanation: Restriction of salt, sugar, or fat should be individualized according to the diagnosis, laboratory findings, medicines, symptoms, and overall nutrient requirements. Unnecessary or excessive restriction may reduce palatability, energy intake, or important nutrients. The correct principle is to meet the patient’s medical needs while preserving adequacy, balance, safety, and acceptability of the diet.

Correct answer: B. Modifying food according to disease, digestion ability and need

Explanation: A therapeutic diet is planned or modified to support treatment while considering the patient’s disease, symptoms, digestion, nutritional requirements, allergies, cultural habits and ability to eat. Therefore, changing the food according to the individual’s medical and nutritional needs is correct. Giving every patient the same food or stopping medicines because of taste is unsafe and does not represent diet therapy.

Correct answer: B. Giving light, low-smell food in small portions

Explanation: Nausea can be aggravated by strong smells, heavy spices, fatty foods and large meals. Small, frequent portions of bland or lightly flavoured food, with fluids offered appropriately, may improve tolerance. The exact plan depends on the illness and clinical advice, but permanently withholding food or offering fried, strongly flavoured food is generally unsuitable. Therefore, option B is best.

Correct answer: D. Providing diet, education, and support according to the patient's problem

Explanation: Nutrition intervention means carrying out planned actions to solve or improve an identified nutrition problem. It may include changing the diet, modifying food texture, giving nutrition education, arranging feeding support, or coordinating care with the health team. The correct answer is D because it describes purposeful help based on the patient's individual nutrition needs.
