Diet therapy

Correct answer: B. Checking the success of the diet plan

Explanation: Dietary follow-up monitors whether the patient is following the plan, tolerating it, receiving adequate nutrients, and moving toward the desired clinical outcomes. Weight, symptoms, laboratory values, intake, and practical difficulties may be reviewed. The plan can then be adjusted safely instead of assuming that the original prescription is working perfectly.

Correct answer: C. To get an indication of nutritional status

Explanation: Weight is a practical measurement that can provide an indication of nutritional status and change over time. Unplanned loss may suggest inadequate intake, illness, or wasting, while gain may reflect recovery, fluid retention, or excess energy depending on the context. Weight should be interpreted with height, body composition, symptoms, intake, and clinical findings rather than used alone.

Correct answer: D. It helps adherence and memory

Explanation: Written instructions provide a clear reference for foods to choose or avoid, portion guidance, meal timing, preparation methods, and special precautions. Patients and caregivers can review them later instead of relying only on memory after counselling. Clear language and confirmation of understanding are important, because written material supports adherence but does not replace individual explanation.

Correct answer: B. On correct planning and regular follow-up

Explanation: The success of diet therapy depends on a diet plan that suits the patient’s disease, nutritional needs, food habits, culture, and tolerance. It must also be followed regularly and reviewed when the patient’s condition changes. Therefore, correct planning together with adherence and follow-up gives the best therapeutic result; cost, colour, and decoration alone cannot treat disease.

Correct answer: C. To maintain nutrient adequacy and interest

Explanation: Food variety is useful because different foods supply different nutrients, including carbohydrates, proteins, fats, vitamins, minerals, and fibre. Variety also improves taste, prevents boredom, and makes it easier for a patient to follow a therapeutic plan for a longer time. Thus, it supports both nutritional adequacy and compliance, whereas offering only one food is nutritionally and practically unsuitable.

Correct answer: A. Because the patient may have difficulty tolerating the food

Explanation: A therapeutic diet should usually be changed gradually because illness may reduce digestive capacity, appetite, or tolerance. A sudden major change can cause nausea, discomfort, poor intake, rejection of the diet, or worsening of symptoms. Gradual modification allows the patient and digestive system to adapt, while professional advice helps ensure that nutritional needs remain covered.

Correct answer: A. Using diet according to a disease or health need

Explanation: Diet therapy is the planned use or modification of food to support prevention, treatment or management of a disease. It may alter energy, protein, fat, sodium, fibre, fluid, food consistency or meal timing according to the patient’s condition. It complements medical care and should be individualized rather than being a random restriction.

Correct answer: B. The patient’s nutritional needs

Explanation: A therapeutic diet must begin with assessment of the patient’s nutritional needs, medical condition, age, weight, usual intake, symptoms, allergies and ability to eat. This information allows the diet to be individualized safely. Utensil cost, room colour and clothing texture do not determine the patient’s nutritional prescription.

Correct answer: A. To help control body weight

Explanation: A low-energy diet reduces total energy intake while providing adequate protein, vitamins, minerals, fibre and other essential nutrients. Its main purpose is usually to support healthy weight control or gradual weight loss when clinically appropriate. It should not mean starvation, removal of water or indiscriminate restriction of all foods.

Correct answer: A. Saturated fat

Explanation: Limiting saturated fat can help reduce low-density lipoprotein cholesterol in many people and may support cardiovascular risk reduction. Saturated fat is found in foods such as large amounts of ghee, butter, fatty meat and some fried or processed foods. The overall pattern should emphasize unsaturated fats in appropriate amounts, fibre and medical guidance.

Correct answer: A. A low-purine diet

Explanation: In gout, uric acid crystals can collect in joints and cause painful inflammation. Purines are broken down to form uric acid, so a suitably planned low-purine diet may help reduce dietary purine load. Hydration and medication are also important, and dietary changes should be individualized because not every patient has identical needs.

Correct answer: A. Giving adequate fluids and oral rehydration solution

Explanation: Diarrhoea causes loss of water and electrolytes, so the first priority is preventing dehydration with oral rehydration solution and suitable fluids. ORS replaces both water and essential salts; continued age-appropriate feeding may also be important. Fried foods and extra chilli are not the treatment, while stopping fluids can make dehydration dangerously worse.

Correct answer: C. Iron

Explanation: Iron is required to form haemoglobin, the protein in red blood cells that carries oxygen. Inadequate iron can lead to iron-deficiency anaemia, although anaemia may also have other causes and should be medically assessed. Iron-rich foods include pulses, meat, eggs and leafy vegetables, and supplementation should be taken only when appropriately advised.

Correct answer: A. Vitamin C

Explanation: Vitamin C improves absorption of non-haem iron found in many plant foods by helping convert it into a form that the intestine can absorb more efficiently. Lemon, amla, guava, orange and tomato can accompany iron-rich meals. Vitamin D has important roles in bone and calcium metabolism, but it is not the specific answer to iron absorption.

Correct answer: A. Balanced energy control

Explanation: Diet therapy for obesity generally aims at a sustainable energy deficit while preserving adequate protein, micronutrients, fibre and hydration. Portion control, nutrient-dense foods, regular activity and behaviour change are usually combined rather than using starvation or extreme restriction. The plan should be individualized according to health status, preferences, medicines and professional advice.

Correct answer: A. Avoiding the identified allergenic food

Explanation: The safest dietary measure is to identify and avoid the food that triggers the allergy, while checking ingredient labels and preventing cross-contact. A healthcare professional can help maintain nutritional adequacy and create an emergency plan when needed. Eating more of the allergen can cause a severe reaction, while avoiding every food is unnecessary and nutritionally unsafe.

Correct answer: A. To know the patient's food habits

Explanation: The main purpose of taking a diet history is to record what, how much, how often, and when a patient eats. It also reveals food preferences, dislikes, allergies, cultural practices, and usual habits. This information helps the dietitian assess nutritional intake and prepare a suitable, practical therapeutic diet.

Correct answer: A. Diet adherence improves

Explanation: Including a patient's food preferences makes the prescribed diet more acceptable, enjoyable, and realistic. When meals respect suitable likes, culture, routine, and available foods, the patient is more likely to eat the recommended amount and follow the plan consistently. Thus adherence and treatment support improve.

Correct answer: A. Helping the patient understand the correct diet

Explanation: Diet counselling gives the patient clear, understandable information about permitted foods, restricted foods, portions, timing, preparation, and the reason for each recommendation. It encourages questions and problem-solving, so the patient can apply the therapeutic diet correctly in everyday life and support disease management.

Correct answer: A. In poor appetite or weakness

Explanation: Small, frequent meals are useful when a patient has poor appetite, weakness, nausea, early fullness, or difficulty tolerating a large meal. Smaller portions reduce the burden on digestion while repeated servings provide energy and nutrients across the day. The exact plan should still follow the patient's condition and medical advice.

Correct answer: A. It can improve appetite

Explanation: Colour, neat arrangement, appropriate temperature, pleasant aroma, and suitable serving vessels can make food more appealing. This sensory appeal may stimulate interest and appetite, especially in a patient who is tired or reluctant to eat. Presentation does not replace nutritional quality, but it can encourage adequate intake.

Correct answer: A. Burning or discomfort in the mouth

Explanation: Food that is excessively hot can burn the lips, mouth, tongue, or throat and may cause pain, discomfort, and reluctance to eat. A safe, comfortably warm temperature protects the patient and supports pleasant feeding. Temperature should be checked before serving, particularly for children, older adults, and weak patients.

Correct answer: A. Light and in small amounts

Explanation: After vomiting, a light, bland, easily digested food in small amounts is generally better tolerated than a heavy, oily, or spicy meal. Small portions given at suitable intervals reduce gastric strain and may lower the chance of renewed vomiting. Fluids and refeeding must be adjusted to the patient's condition and professional advice.

Correct answer: A. Nutritional needs of the mother and foetus

Explanation: A pregnant patient's diet must support the health of both the mother and the developing foetus. Planning considers adequate energy, protein, iron, folate, calcium, fluids, and other nutrients, while also considering symptoms, medical conditions, food safety, and cultural preferences. Food should not be stopped without a clinical reason.

Correct answer: A. Adequate nutrition for growth

Explanation: A sick child still needs adequate energy, protein, fluids, and micronutrients because growth and tissue repair continue during illness. Food should be suitable for age, appetite, symptoms, and ability to digest or swallow. Small attractive meals may help, but severe illness requires assessment and advice from a qualified professional.
