Nutrition

Correct answer: A. Unintentional weight loss and weakness

Explanation: Undernutrition may occur when energy or nutrient intake is insufficient, or when the body cannot properly absorb or use nutrients. Important warning signs can include unintentional weight loss, weakness, fatigue, reduced muscle mass, poor appetite, delayed wound healing, and repeated illness. These signs require proper assessment rather than self-diagnosis, but weight loss with weakness is a relevant clinical clue. Hence, option A is correct.

Correct answer: D. Other safe calcium sources should be considered

Explanation: Avoiding milk does not remove the body's need for calcium. The diet planner should identify suitable alternatives according to the patient's age, health condition, allergies, culture, and overall diet. These may include curd or fortified products when tolerated, calcium-set tofu, ragi, sesame, certain leafy vegetables, or other medically appropriate foods. The exact choice should consider calcium availability and the patient's clinical needs.

Correct answer: A. By controlling the quantity of food eaten

Explanation: Portion control means eating a measured and appropriate quantity of food rather than taking unrestricted servings. It helps regulate energy intake for weight management and can make carbohydrate intake more predictable for people with diabetes. It should be planned according to individual needs and professional advice.

Correct answer: A. It helps keep the meal pattern and carbohydrate intake more consistent

Explanation: Regular meal timing helps distribute food and carbohydrate intake more evenly through the day. This can reduce long gaps or unexpectedly large meals and supports more predictable blood-glucose patterns. It does not replace prescribed medicines, glucose monitoring, or individualized advice from a health professional.

Correct answer: A. Take easy-to-eat, small, and nutritious meals

Explanation: Fatigue can reduce a patient’s ability or willingness to prepare, chew, or finish a large meal. Easy-to-eat foods served in small portions can reduce effort and tiredness, while several meals or snacks across the day can improve total energy and nutrient intake. The foods should still be balanced and selected according to the patient’s medical condition; skipping meals or taking only sweets is not appropriate.

Correct answer: A. To understand the effect of the plan and whether changes are needed

Explanation: Reassessment is a systematic review of the patient’s response after a nutrition intervention. The dietitian or health professional may examine food intake, weight, symptoms, laboratory findings, functional status, and adherence. This information shows whether the nutrition goals are being achieved and whether the plan should be continued, strengthened, simplified, or modified. Thus, reassessment supports monitoring and evidence-based adjustment.

Correct answer: A. Contaminated food can harm a person even when it is nutritious

Explanation: Nutrient value and food safety are separate but essential qualities. Nutritious food supplies energy, protein, vitamins, minerals, and other substances needed by the body, whereas hygiene helps prevent contamination by pathogens, toxins, chemicals, or foreign matter. A contaminated food may retain its nutrients but still cause infection or poisoning. Therefore, good nutrition requires both adequate nutrients and safe handling, preparation, storage, and serving.

Correct answer: A. When support is needed for use of plant-source iron

Explanation: Taking vitamin C with iron-rich plant foods can improve the absorption of non-haem iron in the digestive tract. Useful combinations include lentils, beans, or leafy vegetables with lemon, amla, guava, or another vitamin-C-rich food. Vitamin C does not replace iron, but it helps the body use plant-source iron more effectively. Therefore, option A is correct; the other options are unrelated to iron absorption.

Correct answer: A. Weakening of bones

Explanation: Calcium is a major mineral in bones and teeth, while vitamin D helps the intestine absorb calcium and supports normal bone mineralisation. If both nutrients are deficient, bones may become weak, soft, or more easily fractured, and the long-term risk of disorders such as rickets or osteoporosis may rise. Haemoglobin is primarily associated with iron, not calcium or vitamin D. Therefore, option A is correct.

Correct answer: A. Dehydration

Explanation: Water is essential for maintaining blood volume, cellular function, temperature regulation, digestion, and waste removal. When a patient drinks too little, the body may lose more fluid than it receives, causing dehydration. Possible signs include thirst, dry mouth, weakness, dizziness, dark urine, and reduced urine output. Therefore, dehydration is the correct risk associated with inadequate water intake. The patient’s medical condition should also be considered when planning fluid intake.

Correct answer: A. Including pulses, milk, eggs, or other suitable protein sources

Explanation: Protein is needed for growth, maintenance, tissue repair, enzymes, hormones, immune functions, and many body processes. If a diet lacks protein sources, suitable foods such as pulses, beans, soy, milk, curd, eggs, fish, or meat can be added according to the patient’s preferences, health condition, and dietary pattern. Rice and chapati mainly provide carbohydrates, while oil and ghee mainly provide fat. Fruits and vegetables are valuable foods but do not alone correct an inadequate protein intake. Therefore, option A is correct.

Correct answer: B. It can help the absorption of some iron

Explanation: Vitamin C improves the absorption of non-haem iron, the form found mainly in plant foods. It can help convert ferric iron to the more absorbable ferrous form and can reduce the effect of some absorption inhibitors. Thus, foods such as citrus fruits, guava or tomatoes may be included with pulses and leafy vegetables. This supports dietary iron intake but does not replace medical treatment when anaemia is diagnosed.

Correct answer: C. Include other safe calcium sources

Explanation: Avoiding milk does not automatically mean that calcium needs cannot be met. The diet can include suitable alternatives such as curd or other tolerated dairy products, calcium-set tofu, ragi, sesame, leafy vegetables, legumes or fortified foods, depending on the patient's tolerance, culture and medical condition. The plan should also consider vitamin D and overall dietary adequacy. Therefore, selecting safe alternative calcium sources is the appropriate step.

Correct answer: A. To reduce iodine loss

Explanation: Iodized salt is used to help prevent iodine deficiency, which can affect thyroid hormone production and normal growth and development. Prolonged heating, storage in unsuitable conditions and exposure to moisture may reduce the iodine retained in salt or food. It is therefore sensible to store salt in a closed, dry container and add it toward the end of cooking when practical. This does not mean that all heating removes iodine immediately.

Correct answer: A. Pay attention to fluid intake

Explanation: Dietary fibre adds bulk and can help regulate bowel movement, but many types of fibre work best when adequate fluid is available. Increasing fibre without enough fluid may cause bloating or worsen constipation in some people. A suitable plan usually combines gradual fibre increase, adequate fluids, regular physical activity and attention to the underlying cause. Fluid advice must still be individualised for patients with restrictions such as heart or kidney disease.

Correct answer: A. Checking quantity, quality, variety, hygiene and compliance

Explanation: A broad evaluation of nutrition does not depend on one visible feature of food. It considers the amount eaten, nutrient quality, variety of food groups, hygiene and safety, suitability for the person, and the patient’s ability to follow the plan. Therefore, option A gives the most complete assessment.

Correct answer: B. Micronutrient and fibre deficiencies may remain hidden

Explanation: Stable body weight mainly suggests that energy intake and expenditure may be relatively balanced; it does not prove that the diet supplies every nutrient. A monotonous diet can provide enough calories while lacking vitamins, minerals, fibre and sometimes essential fatty acids or protein quality. A detailed diet assessment is therefore still needed.

Correct answer: A. Low micronutrient and fibre intake

Explanation: Energy-dense foods provide many calories in a small amount, but they may contain little fibre, vitamins and minerals, especially when they are highly processed or rich in added fat and sugar. A patient can therefore meet energy needs while developing poor micronutrient intake. The first assessment should check dietary quality and nutrient density.

Correct answer: B. During energy deficiency, protein may be used as fuel instead of for building and repair

Explanation: Protein is needed for tissue growth, repair, enzymes, hormones and immune functions. When energy intake is inadequate, the body can break down and use protein as fuel, leaving less protein for these important roles. This is called the protein-sparing principle: sufficient energy helps preserve dietary protein for growth and repair.

Correct answer: A. शरीर में उनका भंडारण सीमित हो सकता है

Explanation: Water-soluble vitamins, mainly the B-complex vitamins and vitamin C, are generally not stored in large amounts in the body. Excess quantities are often excreted in urine, although this does not make unlimited intake safe. Regular consumption of varied foods helps maintain an adequate supply. Therefore, option A is correct. They support functions such as energy metabolism, blood formation, immunity, and tissue repair.

Correct answer: B. कुछ विटामिनों के अवशोषण में वसा सहायक हो सकती है

Explanation: Vitamins A, D, E, and K are fat-soluble. A suitable amount of dietary fat helps the body digest and absorb these vitamins, so completely eliminating fat may reduce their utilization and may also lower energy intake. This does not mean that unlimited fat is desirable; the type and quantity should fit the person’s health needs. Therefore, option B is correct.

Correct answer: D. आयोडीन की हानि कम करने के लिए

Explanation: Iodized salt supplies iodine, which is needed for the production of thyroid hormones and normal growth and development. Prolonged exposure to high heat, especially during cooking and storage in open or humid conditions, may increase iodine losses. Keeping salt covered and adding it toward the end of cooking can help preserve more iodine. Thus, option D is correct; heating cannot increase fibre or protein.

Correct answer: A. Energy, protein, vitamins and minerals support the body's defence functions

Explanation: Repeated infections can increase the body's nutritional demands and may also reduce appetite and nutrient intake. Adequate energy and protein support immune-cell production, antibody formation and tissue repair. Vitamins and minerals such as vitamins A, C and D, iron and zinc are needed for normal immune functions, although food alone does not replace medical treatment. Thus, option A is correct.

Correct answer: A. Deficiency of protein, calcium and protective nutrients

Explanation: Normal body weight does not guarantee a balanced or adequate diet. Pulses provide protein and several minerals, milk is an important source of calcium and protein, and vegetables supply fibre, vitamins and protective phytochemicals. If these foods are consistently low, the patient may have hidden deficiencies despite acceptable weight. A nutrition expert should therefore assess diet quality and possible protein, calcium and micronutrient inadequacy. Option A is correct.

Correct answer: C. Vitamin and mineral deficiency can remain even when calories are adequate

Explanation: Hidden hunger refers mainly to deficiencies of vitamins and minerals that may occur even when a person consumes enough calories or has a normal body weight. A diet can provide adequate energy through refined or nutrient-poor foods while remaining low in iron, iodine, vitamin A, zinc, calcium or other micronutrients. Therefore, assessment must consider food variety, nutrient density and diet quality, not calories alone. Option C correctly explains hidden hunger.
